Tomato seedlings have light green leaves. Leaf color change

Tomato seedlings: how to grow them correctly? Tomatoes are very heat-loving plants.

The temperature at which other vegetables feel great can be fatal for tomatoes. This applies to both cold temperatures and too hot temperatures. Also, tomatoes, like seedlings of peppers, are very demanding on air and soil moisture. They need moist soil and dry air. This is especially important during the formation of the root system. If the air humidity is very high, then it is likely that the plant will get sick and die. The light in the place where the tomatoes grow is also of great importance. Tomatoes love light, so even at night they need additional lighting for full growth and development. Tomatoes do not form the first leaf for a long time. After sowing seeds, it takes about 2-3 weeks to form a leaf, and only after 8 weeks a flower brush forms on the plant. All these factors make planting seeds in open ground and their germination on the street is impossible. In this case, grown tomato seedlings at home or in greenhouses come to the rescue.

Growing tomato seedlings from seed selection to picking

Having decided that it is necessary to plant tomato seedlings or pepper seedlings, another question arises about how to grow tomato seedlings so that they are completely ready for transplanting into open ground and full fruiting. First of all, it is necessary to prepare the seeds for sowing. To do this, they are placed in a container with water at a temperature of 20 to 25 degrees. In order for tomato seedlings to be healthy and strong, you can add a few drops of fertilizer to stimulate growth in the water. After that, the seeds are laid out between two layers of wet gauze. After about two days, the seeds will hatch and they can be planted in trays. Another important factor is the choice of the seedling planting date. The question of when to plant tomatoes for seedlings should be decided based on when you plan to plant them in open ground. The best option- 60 days between sowing seeds and planting. In order for the cultivation of tomato seedlings to give the desired results, it is necessary to use right soil with peat added to it and special fertilizers that can be purchased at any store for summer residents. You need to plant seeds at a distance of 4-5 cm from each other. After the tomato seedlings or cucumber seedlings have given the first shoots, you need to provide them with good lighting. When the sprouts are formed, the stem will stretch, and the beginnings of the leaves will appear; the seedlings must be transferred to a cooler place. So, the tomatoes will harden and will be ready for sudden changes in temperature in the future.

Growing tomato seedlings from picking to planting in the ground

In order for tomato seedlings to develop further, it must be dived about 2 weeks after sowing the seeds. For this, ready-made plastic pots are suitable, the size of which must correspond to the size of the plant in order to root system had the opportunity to develop. Picking should be carried out very carefully, trying not to touch the roots with your hands. To do this, the plant is removed from the tray along with a small amount earth and transferred to an already prepared recess in a new pot. Correct fit tomato seedlings after picking should be carried out to a depth just below the first leaves. After 1-2 weeks after picking, it is necessary to repeat the hardening of the seedlings, while watering it as needed. It is better if the tomato seedlings do not bloom before planting in the ground. The plant should bloom already in a permanent place after transplantation, then the fruits will be large and dense. The temperature regime when growing seedlings of tomatoes, after germination for 7 days, is maintained at 16 - 18 ° C during the day, and at night 13 - 15 ° C. Then it can be increased to 18 - 20°C during the day and 15 - 16°C at night. This regimen is observed until the seedlings grow in the box (up to the second or third true leaf), which is approximately 30-35 days after germination. During this period, the seedlings are watered 2-3 times. This mode of watering during the period of low light (March) does not allow seedlings to stretch. In order to grow tomato seedlings, the first time they water a little, when all the seedlings appear, and then after 1 - 2 weeks. The last time they are watered on the day of picking seedlings, 3 hours before picking. Water should have a temperature of 20 ° C. A few more tips for caring for seedlings in boxes. Boxes or drawers need to be turned almost every day the other side to window glass so that the seedlings do not stretch to one side. The main thing - do not get carried away frequent watering, when watering, try not to let water fall on top of the leaves, it is better to water under the roots. Water must be settled. Do not forget to spray the plants with skim milk. To do this, take half a glass of skimmed milk, dilute it in 1 liter of water and spray the plants in the morning so that the leaves are moistened. Spraying seedlings is done after the appearance of two true leaves. Processing with skim milk will help get rid of viral diseases that cause leaf curl. In a box, seedlings grow without top dressing. It is impossible to put the box directly on the windowsill, it is better on some kind of stand, so that air access to the root system is not limited.

picking

Seedlings with two or three true leaves are dived (transplanted) into pots 8 × 8 cm in size, in which they will grow for only 20 - 22 days. To do this, the pots are filled with one of the soil mixtures recommended above and watered with the following solution: 0.5 g of potassium permanganate (pharmaceutical manganese) is diluted in 10 liters of water (22 - 24 ° C). When picking seedlings, sick and weak plants are culled. If the seedlings are slightly stretched out, then the stem can be half-buried when picking into pots, but without deepening (not falling asleep) the cotyledon leaves, and if the seedlings are not stretched out, then the stem is not buried in the soil. - 22°С, at night 16 - 18°С. As soon as the seedlings take root, the temperature is reduced during the day to 18 - 20 ° C, at night to 15 - 16 ° C. Water the seedlings in pots 1-2 times a week until the soil is completely wet. Before the next watering, the soil should be a little dry, but at the same time, it is necessary to ensure that there are no long interruptions in watering. 12 days after picking, the seedlings are fed: 1 tablespoon of nitrophoska or nitroammophoska is taken for 10 liters of water. Spend about a glass of solution per pot. After 20 - 22 days, the seedlings are transplanted from small pots to large ones (12x12 or 15x15 cm in size). When transplanting, try not to bury the plants. After planting, the seedlings are watered with warm (22 ° C) water, trying to moisten the soil well. Then do not water. In the future, moderate watering is needed (1 time per week). Each plant is watered individually as the soil dries up. This restrains the growth and stretching of seedlings. Many gardeners will probably ask the question: why do you need to dive seedlings first into small pots, and then plant them in large ones? Firstly, each transplant slows down the growth of the plant, and the seedlings do not stretch. Secondly, when the plants are in small pots, they develop a good root system with normal watering, since water does not linger in them and there is more air access. If the seedlings are immediately dived into large pots, then it is difficult to regulate watering, the water stagnates there. Overwatering often occurs, and the root system stops growing due to lack of air, which in turn negatively affects the development of seedlings (it stretches). 15 days after transplanting into large pots, seedlings are fed: for 10 liters of water, take 1 tablespoon of superphosphate and 2 tablespoons of wood ash, spending one glass of the solution for each pot. After 10 days, a second top dressing is done: 2 tablespoons of nitrophoska or nitroammophoska are taken for 10 liters of water, spending 1 glass per plant. Watering is combined with top dressing. During the period of growing seedlings, no bedding soil mixture do not do.

If the seedling has a pale green color

If the tomato seedlings are pale green in color when pulled out, it is necessary to feed (1 tablespoon of urea is taken per 10 liters of water), spending half a glass for each pot, and put the pots for 5-6 days in a place where the air temperature is like during the day, so at night it stays at 8 - 10 ° C, and do not water for several days. It will be noticeable how the plant stops growing, turns green and even acquires purple hue. After that, the plants are again transferred to normal conditions.

If the seedlings stretched out

In rare cases, if the seedlings are very elongated, the stems of the plants can be cut into two parts at the level of 5 or 6 leaves. The upper cut parts of the plants are placed in a jar of water, where after 8–10 days roots up to 1–1.5 cm in size will grow on the lower stems. Then these plants are planted in nutrient pots 10–10 cm in size or directly in a box with a distance from each another 10x10 or 12x12 cm. Planted plants will continue to grow like ordinary seedlings, which are formed into one stem. New shoots (stepchildren) will soon appear from the axils of the 5 lower leaves of the cut plant that remained to grow in a pot. When they reach a length of 5 cm, the two upper shoots (stepsons) of them must be left, and the lower ones removed. The left upper stepchildren will gradually grow and develop. The result is a good standard seedling. This operation can be done 20 - 25 days before landing on permanent place. When planting these seedlings in a permanent place in the greenhouse, they continue to form it in two shoots. Each shoot is tied separately with twine to the trellis (wire). Up to 3-4 fruit clusters are formed on each shoot. Much attention should be paid to the planting time of the tomato. If, say, a cold snap is expected in the afternoon and a frost at night, then the plantation where the tomatoes are planted should be watered. Moist soil better transfers heat from the lower layers to the surface, so the temperature of the watered soil is set 2-3 ° C higher than dry soil. When hardened seedlings are planted in abundantly watered soil, it is able to tolerate frosts down to -2 ° C. http://nachaloes.ru

If the seedling grows slowly

Many gardeners complain about the slow growth of seedlings, in which case they are fed with a growth stimulator - sodium humate. The watering solution should be the color of beer or tea. Pour 1 cup per plant.

Seedling hardening

15 days before planting, tomato seedlings are hardened, that is, they open the window both day and night. On warm days (from 12 ° C and above), the seedlings are taken out to the balcony for 2 - 3 hours for 2 - 3 days, leaving it open, and then taken out for the whole day, you can leave it overnight, but it is necessary to cover the top with a film . In the event of a decrease in temperature (below 8 ° C), it is better to bring the seedlings into the room. Well hardened seedlings have a bluish-purple tint. When hardening, the soil must be watered, otherwise the plants will wither.

If the seedlings are fattening

If the seedlings are developing rapidly, getting fat, they do root top dressing: 3 tablespoons of superphosphate are taken for 10 liters of water, spending a glass of this solution for each pot. A day after feeding, the seedlings should be placed in a warm place where the air temperature is kept at 26 ° C during the day and 20 - 22 ° C at night, and do not water for several days, slightly drying the soil. Under such conditions, the seedlings are normalized, and after a week they are transferred to normal conditions. In sunny weather during the day, the temperature is kept at 22 - 23 ° C, at night 16 - 17 ° C, and in cloudy weather it is reduced during the day to 17 - 18 ° C, and at night to 15 - 16 ° C.

How to determine the quality of seedlings?

Seedlings should be 25 - 35 cm high, have 8 - 12 well-developed leaves and well-formed inflorescences (one or two). Often, gardeners buy seedlings on the market, grown without observing the rules of agricultural technology, and without knowing the variety. The main disadvantage is that the seeds are sown in late dates. This can be determined by the type of plant, they are pale green in color, with large internodes, thin, elongated and without signs flower buds. Such thin, loose, easily breaking seedlings always give a late and meager harvest, they are mainly affected by fungal diseases, especially late blight, so I advise you to grow seedlings only by yourself. 2-3 days before planting seedlings in a permanent place, it is recommended to cut 2-3 lower real leaves . This operation is done in order to reduce the possibility of diseases, better ventilation, lighting, which in turn will contribute to better development first flower brush. Cut so that there are stumps 1.5 - 2 cm long, which then dry out and fall off on their own, and this will not damage the main stem.

Tomato seedlings for open ground

It is planted in pots 10x10 cm, and tall species are planted in pots 14x14 cm in size. Before planting, the seedlings should be watered, so that later they can be dug up normally and carefully pulled out of the ground without damaging the roots of the plant. Seedlings are also sorted, discarding weak or diseased plants. Soil is poured into the pot, slightly compacted and a small depression is made in the middle. The seedling is lowered there so that its root is straight. After about two weeks, you can pour a mixture of peat and sand into the pots. Quality care consists in proper feeding tomatoes, watering and temperature control. Plants should be watered once a week only. warm water. As the plant develops, watering is increased so that the soil does not dry out. It is best to water in the morning. During the growth period, the plant can be sprayed with skim milk once a week. This is done so that the plant does not have viral diseases. Every two weeks they are fed with a solution of nitrophoska. The last top dressing of the plant is carried out a week before planting in open ground. There are also quite a few importance has hardening seedlings. To do this, you need to take the seedlings outside for a short period of time.

To preserve the flower buds on the first flower brush, it is necessary to spray the seedlings with a boron solution 4-5 days before planting in the garden or in the greenhouse (1 g per 1 liter of water). boric acid) in the morning on a cloudy day. In sunny weather, this cannot be done, otherwise burns will appear on the leaves.

Keep in mind! Before planting in open ground, be sure to harden the seedlings. You need to start hardening in cloudy weather, gradually accustoming the seedlings to direct sunlight.

The pale dull color of the leaves indicates a lack of light or nitrogen fertilizers.

To protect the sprouts of new plants, steam the soil before sowing. At the initial signs of the disease, diseased seedlings with a lump of soil near them should be removed, watering should be stopped and calcined sand should be poured under the stems. After that, pour a solution of potassium permanganate or preparations "Fundazol", "Topsin". But the most reliable way- transplant young sprouts into new, disinfected soil.

What to do if tomato seedlings stretched out?

Elongated tomato seedlings

You did it! Shoots have appeared, but they do not shed the outer shell. What is the reason? Usually this happens with weakened, completely unformed seeds, it is better not to dive into such specimens, but to throw them away. There are several reasons for the phenomenon: If tomato seedlings do not grow well, then it is worth taking action, otherwise it can lead to poor growth tomato in general and poor yields. To make seedlings grow more actively, it is worth using a growth stimulator, for example, sodium glumate. A solution that fertilizes in color should resemble tea or beer. Watered with the calculation of 1 glass per plant. Stops growing in height

not enough nitrogen

Stretch prevention

not enough good lighting If the tomato seedlings stretched out very much, you need Tomato seedlings stretched out - it doesn't matter! And this one, it would seem, at first glance bad moment can be turned into a positive result. Namely, from one plant you can grow two at once. Cut the tomato into two parts at the level of 5-6 leaves. The trimmed top plants should be placed in a container of water. And in about a week they will give roots measuring 1.5 - 2 cm. Then they must be planted in pots or in a box at a distance of 10 cm from each other. They will grow like seedlings that will need to be formed into one stem.

What are the seedlings missing? Seedlings are moved to a lighted place or backlight is used (40-watt Fluorescent Lamp, installed at a distance of 14-25 cm above the plants). The quality of seedlings from seeds sown later and growing at natural light, better than early sowing under the lamp. In addition, the reasons for the unexpected lodging of seedlings are:

Seeds sprout together when the material for sowing is of the appropriate quality. But the reason for sparse shoots sometimes lies elsewhere.

Why are tomato seedlings stretched?

excessively superficial sowing;

An uneven layer of substrate is poured onto the seeds. As a result, seeds located at a considerable depth give inferior seedlings or they do not have enough strength to get through the thickness of the soil and they do not germinate at all. They hastened to remove the film or glass from the container with crops. This led to the drying of the seed coat. The main reason is the unviable old seed. To make sure otherwise, do a quick germination test. To do this, first soak the seeds in the stimulator, and then place them in a damp paper towel and dip them in a plastic bag for a while. Keep the sachet in a warm place until small sprouts appear.​

The stem thickens when the plant stops growing in height, which is exactly what is needed in order to grow powerful, stocky seedlings. You need to understand that this operation is carried out when at least one leaf has formed at the points of growth. Repeated pruning will improve the result and tomato seedlings with strong and thick stems will surprise everyone. Even cotyledon leaves are often cut off and this always leads to an exclusively positive result.

    Methods for preparing top dressing for tomatoes:

each stalk of a tomato. The cut should be done after the fifth leaflet. top plants need to be put in a jar of water, for the formation of roots, this happens within one week. After the root system has appeared, the upper parts of the tomato must be placed in pots for seedlings. The result is another tomato seedling and it can also be grown outdoors. If the tomato seedlings have stretched out and turned pale green, then it's time to feed them with useful trace elements. Make a nutrient solution for 10 liters of water, add 1 tablespoon of urea. Water each plant with half a glass and remove the seedlings to a place where the temperature is constant 8 - 10 degrees and do not water for a couple of days. You will notice that the seedlings have stunted and may have changed color, either dark green or purple. After such changes, it is necessary to put the seedlings under normal conditions. After all, this is often caused simply by a lack of some kind of nutrient, excess moisture in the soil, cold soil in pots, pests that have settled on the underside of the leaves, a disease that begins. If the plants lack nitrogen, they look stunted: the stalk is thin, the leaves are small, pale green, turn yellow from below and die. And, conversely, with an excess of nitrogen, they fatten: the stem and petioles are thick, the leaves are large, dark green.

Innovative solution

In case of nitrogen deficiency, fertilizing is carried out with a solution of ammonium nitrate or urea (not exceeding the proportion of 7-11 g per 10 liters of water). Blue-red spots on the foliage indicate hypothermia of the soil and the inaccessibility of phosphorus to the roots of plants. Dry border is a sign of potassium starvation. In both cases, the plants are fed complex fertilizer, and create favorable conditions for them.​ Excessive moisture, from which seedlings can suffocate in the soil; Use of a clay weighted substrate for planting seeds. The “crust” created after watering does not give the seedlings a chance for full development. They are unable to break through it.

To eliminate the error, periodically moisten the “hats” so that the sprouts can shed the shell on their own, or gently, trying not to injure the delicate greens, pry them with a needle. Do not touch with your hands, because the risk of death of seedlings in this state is very high.

​If you don't see any change after a week or so, it's probably bad seeds. You need to purchase fresh seed and start the process over. Many types of seeds are useful after a couple of years of proper storage.Tomatoes are the most common vegetable plants in the world. There is very little information about their origin, many scientists believe that the birthplace of this fruit is Peru and the mountainous regions of Ecuador. Tomatoes are very Nitrogen-containing top dressing can be prepared in a bucket of water, dissolving one tablespoon of urea there and watering each bush in half a glass.

If tomato seedlings grow poorly

After a while, small stepchildren and shoots begin to appear near the axils of the leaves. It is necessary to wait until the upper shoots reach five centimeters in length, after which it is necessary to remove the lower stems. This must be done

If the seedling grows and develops very quickly, then it is necessary to supply it useful substances. Prepare a solution, add 3 tablespoons of superphosphate to 10 liters of water. Water each plant with one glass of solution and put it in a warm place where the temperature is 26 degrees during the day and 22 at night. As in the previous example, do not water for several days. In a week, the seedlings will return to normal and create the usual conditions.

With a lack of phosphorus, a red-violet hue appears on the leaves (more often on the underside), and chlorosis on the lower leaves is discoloration of the tissue between the veins. If the ends and edges of the old (lower) leaves turn yellow, then this clear sign lack of potassium. At the same time, the leaves of tomato seedlings can twist down.

Why don't seeds germinate

  • low soil temperature, contributing to the decay of the roots;

​Please note! An exceptionally light substrate should be used, it is better if the basis is neutral peat or crushed vermiculite. The height of the mulching layer should be equal to the diameter of the seeds to be planted.​

  • Germination of seeds
  • Also, the cause of failure is excessively deep sowing. Be sure to consider when planting the specifics of sowing various plants. Some prefer surface placement in moist soil under polyethylene, such as celery, other seeds are planted under a thin layer of substrate, etc.

The seedlings will then give large quantity fruits than frail sprouts that have grown in cramped conditions. It is more convenient to take care of twenty bushes than fifty, giving the same amount of harvest.

  • One of the most important problems in growing tomatoes is pulling seedlings. Seedlings grow, leaves touch neighboring plants and a struggle for living space and light begins to take place. This is a natural reaction of seedlings going through all stages of growth to produce seeds. To complete life cycle the plant reaches for the streams of light, because the process of photosynthesis depends on it. The stems do not become thicker, quickly turn yellow and old leaves begin to fall off at the bottom.
  • How much fertilizer to give each plant?

Dive errors are a common cause. For example, long roots of seedlings are not pinched, and when planted in a substrate, they bend and intertwine. This leads to rotting and inhibition of plant growth or to its death from fungal diseases, the pathogens of which penetrate through the damaged root system.

  1. Such pictures can be observed in most lovers of self-growing seedlings. What to do so that the seedlings do not stretch? What is the way out, and is there any at all? Why is this happening? Of course, there is a way out. Required
  2. Young tomato seedlings need phosphorus. This plant does not absorb it well from the soil. If the situation is not controlled in time and fertilized with phosphorus, the seedlings will slow down growth, and their leaves will turn dark purple.

If an air cavity has been created around the roots during planting. As a result, the root hairs dry out and do not fully function.

  1. Excessively acidic or alkaline soil;
  2. Maintaining the wrong temperature and soil moisture.
  3. Lack of light. Not getting enough light, the seedlings begin to reach for the nearest source. Place them directly under the lamp or purchase special lamps for indoor plants which provide the wide spectrum of light required by the plant. Seedlings grow better with 15 hours of light per day.

Stages of seed development

Lodging of seedlings and their death

Anyone who wants to enjoy the taste of self-harvested tomatoes in their own garden faces many difficulties, because growing tomatoes at home requires a lot of effort and patience. To receive good harvest tomato, it is necessary to grow very capricious and constantly requiring care and attention seedlings. If you do not take into account all the rules, it is unlikely that she will live to the moment when you need to plant her in the ground.

move to a cool place

watered and fertilized abundantly

  • When planting tomato seedlings in the ground, it is imperative to deepen the stems. There is no need to make the holes very deep, because after the winter, the earth does not have time to warm up, it is enough to be able to plant on a slope. First you need to form grooves, they should be eight or ten centimeters deep, pour water and wait until complete absorption occurs. After that, you need to spread the tomatoes along the grooves, the tops of the bush should not be closer than fifty centimeters to each other. It is better to lay the roots to the south so that the plant straightens up, reaching for the sun.
  • create good conditions
  • Fertilizing the soil with nitrogen, you need to be extremely careful. With an abundant supply of these elements, the seedlings are drawn out, and this leads to a delay in flowering and fruit set.
  • Low temperature and lack of nutrition.
  • an overabundance of trace elements;
  • Oversaturation of seeds with initial treatments to "improve germination."
  • Remember! Seeds do not need light to germinate heat, and for seedlings, light and a decrease in temperature are essential. Therefore, three days before germination, lower temperature regime and create maximum illumination. Use a fan to circulate the air.​

Also one of the reasons is the steaming of seeds. It is impossible to place a container with planted moistened crops in an overly warm place (for example, a battery). To avoid steaming, place a stack of magazines or books under the bowl, or purchase special thermal mats.​

Leaf color change

Growing a tomato takes a lot of time, but the result is worth it. Unfortunately, things don't always go smoothly. Sometimes tomato seedlings grow poorly or the seedlings stretch out, and it happens when the seedlings become pale green. It is quite possible to deal with these problems, the main thing is to know exactly how.

Where the temperature will be about ten degrees and wait until the color returns to normal, then return the seedlings to their original place. As a result, not only the color is restored, but growth also stops a little.

they begin to grow rapidly and stretch upward. Seedlings need to be watered only when the ground becomes dry.

Main reasons:

for seedlings. You need to treat this very responsibly.

Growth halt after picking

  • Growing tomatoes in a greenhouse, the soil must be prepared in the fall. For each square meter, one bag of rotten woody leaves should be poured and immediately loosened. And in mid-April, it is enough to apply 10 g of nitrophoska to the same place, then dig again. This procedure makes the soil moist enough and the tomatoes will not suffer from drying out.
  • Some types of plants perceive picking negatively. These include all varieties with a taproot and weak root system - cucumbers, peppers, etc. Such plants are planted in open ground, and peppers and cucumbers are sown in separate pots, several pieces.
  • Cat urine affects the color of seedlings and may cause lodging.

Uneven seedlings of tomatoes

Close location. To eliminate, move the pots apart or carry out an extraordinary picking of plants into a larger container. But keep in mind that each pick slows down the development of plants for 11-15 days. Often in this way they delay the planting of seedlings in the ground under unsuitable weather conditions.

​Please note! Hard coated seeds (spinach, radishes, beets, etc.) prefer cool temperatures when germinating. It is better to plant them directly in open ground.

Sometimes there are situations when seedlings are very stretched. In this case, it is worth cutting the stems of plants into 2 parts, focusing on 5 or 6 leaves. The cut pieces are placed in water. Roots will grow on these stems in 10 days, the size of which will be 1-1.5 cm. These stems should be planted in pots or directly in a box, while the distance between plants should be at least 10 cm. These stems will continue to grow as usual seedlings

» Tomatoes (tomatoes)

Experienced gardeners claim that tomatoes are a strong and sustainable crop. Caring for them is quite simple, and the harvest almost always pleases the owner of the site. However, not every newcomer achieves good yields. Either pests spoil seedlings, then diseases appear, then the leaves of plants turn white. In order to save a vegetable crop in time, you need to have basic skills in caring for an annual plant.

There are several reasons why the leaves of seedlings may turn white and then dry out. Very often the problem occurs due to sunburn on young plants. The first step to confirm the cause is to inspect the greenery. Sunburn affects partially or everywhere the leaves and they can become covered with white spots, begin to thin. White dots can appear not only from exposure to the sun when transplanted into open ground, but also while on the windowsill, living in cups, and even in a greenhouse.

What can you do to avoid sunburn? Is it possible to reanimate landings? Compliance simple rules will allow gardeners to prevent the occurrence of this trouble:


Close-up of tomato seedling
  • In no case should you immediately plant seedlings from a shaded place under the open sun. It is necessary to gradually accustom the green shoots to the sun's rays, otherwise the tomatoes will dry even more. To do this, cups with seedlings should be taken out daily for 20-30 minutes. Gradually, the time spent in the air increases and as soon as the time is right, the tomatoes can be transplanted into open ground.
  • Not less often, chemical burns become the cause of the appearance of white spots on the foliage of tomatoes. They appear due to an increase in the recommended dosage. chemical fertilizer during the preparation of the solution. Excessive density of the solution, hitting the plants, provokes the appearance of white spots on the foliage. Gradually, the affected greens die off.
  • There are times when green leaves are covered with white spots due to the manifestation of various diseases.

Some chemical preparations can be used only in cloudy weather, so as not to provoke a decrease in the degree of natural protection of plants from sunlight. Very often, ignoring these rules leads to the death of seedlings.

Diseases of adult plants in the greenhouse and open field

Low yields are provided to gardeners who believe that tomatoes do not require care and fertilization. Only proper care of the vegetable crop will make it possible to form weighty fruits that will delight the owner of the tomatoes. When there are white spots on the green growth, it is necessary to identify the cause of their appearance. Not only pests, but also unpleasant diseases, such as:

  • brown spotting;
  • white rot;
  • powdery mildew;
  • septoria;
  • late blight.

brown spot

With the appearance of brown spotting, tomato leaves turn white. In addition, seedlings are subject to a number of concomitant diseases. Basically, this disease affects greenhouse annual plants.


With brown spotting, spots from white become dark

The main signs of brown spotting include:

  • the appearance of a white fluff on internal parts leaf plates of tomatoes;
  • gradual modification colors plaque, a smooth transition from white to dark brown;
  • the appearance of yellowness on the outer part of the foliage.

The development of the disease can be stopped at the initial stages. If you ignore the symptoms, then the foliage of tomatoes will gradually curl, and the plant will soon die. To prevent brown spotting, seedlings should be provided with regular ventilation and a decrease in the degree of humidity. Such methods will help prevent the consequences of a devastating scourge.

The occurrence of white rot negatively affects the leaves and stems vegetable crop. The vegetative part of the seedlings is covered with white spots, the stems become soft and a plaque forms on them, resembling a mucous membrane.


To prevent the death of the bushes, urgent therapy is necessary. To do this, you need to strictly adhere to the advice of experts:

  • First of all, we eliminate the infected part of the seedlings.
  • We treat the cut points with a solution blue vitriol.

As a preventive measure against white rot, you can use a universal remedy called Bordeaux liquid. Spraying seedlings will save tomatoes from an unpleasant disease.

Powdery mildew of tomatoes

Light foliage of tomatoes can signal the appearance powdery mildew.The main signs of misfortune are:

  • a grayish-white coating on the lower part of the foliage;
  • yellowness from the upper side of the foliage.

The disease develops quite rapidly. Leaves dry out quickly annual plant dies. It is very important to pay attention to the affected tomatoes in a timely manner and carry out proper treatment. Defeating powdery mildew is incredibly difficult.

It is best to take preventive measures in advance. High level air humidity and frequent fluctuations in the degree of moisture become ideal conditions for the appearance of an unpleasant disease.


During periods of high humidity, experts recommend treating the bushes with special means, namely:

  • Fundazol;
  • Topaz;
  • Previcur;
  • Vitaros.

Septoria no less than other diseases destroys tomato seedlings. fungal infection spreads quickly enough through the greenery of tomatoes and forms many yellow-brown spots.

Elimination of manifestations this fungus possible in two stages:

  • cutting off the affected vegetation of the bush;
  • treatment of plantings with fungicidal agents like Bordeaux liquid, Baktofit.

The appearance of late blight

Almost every experienced gardener has encountered late blight, which destroys not only tomatoes, but also potatoes. The primary signs of phytophthora are:

  • the appearance of spots of brown-brown shades with a white edging along the extreme parts sheet plate;
  • rapid increase in spots;
  • the appearance of a light coating resembling a cobweb on the lower part of the foliage;
  • yellowing of the leaves, their further folding and drying.

The stems of the plant gradually turn into dust, break and the seedlings die. Only timely processing will prevent the death of the bushes.


How to deal with white spots on tomato leaves

Carrying out the treatment of leaves affected by white bloom is not always effective. That is why it is better to take care of preventive measures, which will save the bushes from pests and various infections. Experienced gardeners believe that it is important to plant seedlings correctly, which also affects the stability of a vegetable crop.

To prevent the appearance of white spots on the foliage, it is necessary to reasonably select a site for planting seedlings. Plants should receive a sufficient amount of sunlight, which will not make it possible to provoke excessive effeminacy of the shoots.

In the case when the seedlings were in the shade for a long time, and then were planted in open ground on sunny side, most of the bushes soon became covered with white spots from sunburn and died. Even when the seedlings are barely visible from the ground in a cup, they must be systematically taken out into sunlight so that they get used to such an environment.


Do not abruptly transfer tomatoes from the shade to the sun. The transition must be gradual

It is equally important to take care in advance of protecting the bushes from the occurrence of various diseases. For this you need:

  • pre-select and prepare the soil for planting tomatoes;
  • to introduce fertilizers recommended by specialists into the soil, which will increase the ability of plants to counteract diseases of various types.

During the spraying of seedlings using chemicals instructions must be followed exactly. This will avoid chemical burns and further death of plants.


Proper care for seedlings of tomatoes will help to avoid problems in the future

In cases where white spots from sunburn appeared on the foliage of tomatoes, it is no longer possible to return the green color. However, using special means you can help the bushes recover, and grow with a new green mass.

After sunset, you can process tomatoes using Espin. Similar procedures should be carried out every 6-7 days for 3 weeks. These activities will provide the plants with a sufficient amount of nutrients.

If the seedlings still received sunburn, then its fruiting will be delayed by 7-14 days, unlike healthy bushes.

If the seedlings immediately stretched out without having time to grow normally, then you can save it. There can be several reasons for pulling seedlings. This is, firstly, a very high temperature, which happens in our apartments, more than 20 degrees, it is necessary to lower it, you can remove the second frames, cover the batteries central heating, open the window. The second reason is the lack of lighting, you can put a fluorescent lamp on the window and illuminate the seedlings in the morning and evening. Do not sow seeds early when there is not enough light, stick to optimal timing sowing. To save the seedlings, we need to thread them, we often grow more seedlings than necessary, then add earth. The second option is to cut the stem, the incision is made above the fifth leaf. The top needs to be put in water and when roots appear in a week, you can plant them like ordinary seedlings in the ground. On the second part of the seedlings, shoots will appear, we leave only a couple of the top ones, and cut off the rest, you need to do this 20-25 days before planting.

Plant in the OG, they will quickly catch up with their own, and in pots they will suffer. Cover with jars, film, covering, if you are so afraid.

Stretch prevention

Good luck to you. For the first time, seedlings should be fed 10 days after germination with a solution of nitrophoska (a pinch per 1 liter of water). Useful for the human body

Dilute one tablespoon of urea into ten liters of water and the liquid that turned out to be poured over the tomatoes on the windowsill. No need to be greedy when planting tomatoes in boxes. Do not stuff a large number of tomatoes in one box. Better smaller bushes, but healthy and strong. The seedlings will then bear more fruit than the feeble sprouts that have grown in crowded conditions. It is more convenient to take care of twenty bushes than fifty bushes that give the same amount of harvest.In 3 weeks

One of the most important problems in growing tomatoes is pulling seedlings. Seedlings grow, leaves touch neighboring plants and a struggle for living space and light begins to take place. This is a natural reaction of seedlings going through all stages of growth to produce seeds. To complete the life cycle, the plant reaches for the streams of light, because the process of photosynthesis depends on it. The stems do not become thicker, quickly turn yellow and old leaves begin to fall off at the bottom.

Why are tomato seedlings stretched?

If the tomato seedlings are very stretched, then you need:

Such pictures can be observed in most lovers of self-growing seedlings. What to do so that the seedlings do not stretch? What is the way out, and is there any at all? Why is this happening? Of course, there is a way out. Required dive it, that is, tear it off lower part(long root) and plant again); To slow down the growth of seedlings upwards and vice versa, to strengthen the growth of roots and strengthen the trunk, you need:

although this is not a problem at all. So the solution

    Apparently you grew seedlings incorrectly: the soil is very poor on nutrients, little light, excessively warm room. Accordingly, it is necessary to correct it - to feed (Athlete was correctly advised, but you can use mineral water or organic diluted in water), more light (lateral), cooler ambient temperature. And they plant elongated seedlings at an angle of 45 degrees. - and new roots are formed and the height of the seedlings will not affect its stability. Choose the right soil next time.​

    I do not agree with the Dachnitsa that top dressing should be started 10 days after germination (!?). The root system is just being formed, top dressing is not needed, in worst case just dangerous. Then a pick, the soil is usually filled with fertilizers. And 10-14 days after picking, it is already necessary to look at the state of the seedlings. If the leaves turn pale (become light green), you can feed with saltpeter or urea (half a teaspoon per 1 liter of water) and increase the lighting. It can be taken out on a glazed balcony on sunny days. If there is an effect of nitrogen fertilization, then the seedlings really do not have enough nutrition; then after two weeks feed her with Kemira or any ud-eat for seedlings.

​If available bird droppings 15 parts of water are taken for one part of it and mineral fertilizers are not added to the resulting solution. Everyone who wants to enjoy the taste of tomatoes picked on their own in their own garden faces many difficulties, because growing tomatoes at home requires a lot of effort and patience. To get a good tomato crop, it is necessary to grow seedlings that are very capricious and constantly require care and attention. If you do not take into account all the rules, it is unlikely that she will live to the moment when you need to plant her in the ground. Move to a cool place

Innovative solution

Watered and fertilized abundantly When planting tomato seedlings in the ground, it is imperative to deepen the stems. There is no need to make the holes very deep, because after the winter, the earth does not have time to warm up, it is enough to be able to plant on a slope. First you need to form grooves, they should be eight or ten centimeters deep, pour water and wait until complete absorption occurs. After that, you need to spread the tomatoes along the grooves, the tops of the bush should not be closer than fifty centimeters to each other. It is better to lay the roots to the south so that the plant straightens up, reaching for the sun.Create good conditions

Move to a more lit and cool place;

1) rearrange the seedlings to a more lit place, even better on a balcony. This is a pick Elena Smirnova answered very reasonably, seedlings - into the ground and cover for the first time with improvised materials: where with a film, where with lutrasil, where with a newspaper or a can. If you live in a country house, you can just close it with leaky buckets at night, as our grandmothers did.

Good growth of tomato seedlings is observed when it is fed with wood ash, which contains a lot of potassium, phosphorus and various trace elements. For 1 liter of water, take 6-8 g of ash and add 1.5-2 g of ammonium nitrate. Such top dressing of tomato seedlings is usually done 10-12 days after the first.
Top dressings are root - when the solution flows into the soil under the plants and foliar - the plants are sprayed with a solution over the leaves. Also, top dressing is divided into mineral and organic. Mineral fertilizers - ammonium nitrate, urea, Kemira-lux, Aelita, Polifid, Agricola, Zdraven and others, as well as wood ash. From organic dressings apply - chicken manure, mullein manure, liquid fertilizers"Ideal", "Chippolino", etc.

For the second time in my life I grew tomato seedlings. Nothing came up that year. This time I sowed often, and they all, damn it, took and rose. There was nothing to dive into, it’s a pity to tear out the extra ones. In general, they grew dead-dead. My husband said - throw it out, buy normal seedlings from the collective farmers, but I did not succumb to provocations. We decided that if they die, we will buy normal ones and plant them - after all, they sell seedlings until mid-June. I brought it to the dacha, planted this dead meat, covered it with spunbond, three weeks passed - they are so strong, large, buds have already appeared on early varieties.

In winter, daylight hours are reduced, respectively, plants need additional lighting. cut into two pieces Your seedlings are stretched out because they do not have enough light, you need to illuminate them with a fluorescent lamp. If it is stretched out too much, throw it away, it will no longer be of any use. When you plant the next one, feed it with special fertilizer for seedlings, it does not allow it to stretch.

plant immediately. But I would not water with an athlete, a tomato is like a weed, if you plant it lying down, it will quickly give lateral roots and catch up with its own. Just fertilize the bed, not sparing, with humus.

Well, if there is enough sun, let them harden! I live in Vladimir, 170 km east of Moscow. For a month now, tomatoes have been standing on the street under a car shed, slowly transporting them to the dacha, burying my neck there. Even the weak are so strong! They stand gray with emerald leaves and gain color! Eh! it was necessary to listen to the Legend and even then landed on the dacha! Simply stupid! He probably cracks salads in St. Petersburg!))) So plant a couple of bushes of your tomato lying down (I dug the first flower brush) and they will gain strength from you, releasing a new root system. And if the cold comes, so what? We live in a zone of risky agriculture! Moreover, something incomprehensible is happening with the climate and ecology! Good luck!)))​

To make the seedlings stretch less, add soil and pinch a couple of lower leaves.

The stem thickens when the plant stops growing in height, which is exactly what is needed in order to grow powerful, stocky seedlings. You need to understand that this operation is carried out when at least one leaf has formed at the points of growth. Repeated pruning will improve the result and tomato seedlings with strong and thick stems will surprise everyone. Even cotyledon leaves are often cut off and this always leads to an exclusively positive result.

Methods for preparing top dressing for tomatoes:

each stalk of a tomato. The cut should be done after the fifth leaflet. The upper part of the plant must be placed in a jar of water, for the formation of roots, this happens within one week. After the root system has appeared, the upper parts of the tomato must be placed in pots for seedlings. The result is another seedling of tomato and it can also be grown outdoors.

In such cases, I do not throw away the seedlings, I let it grow further. When planting in the ground on the street, I break off the lower leaves, let them dry for about 10 minutes, then plant them lying down, sprinkling the stem with the torn leaves off the ground. A tomato planted in this way acquires new roots and becomes stronger.

Seedlings are stretched out due to lack of light. If stretched out, sprinkle and illuminate. Additional lighting it is better to carry out with LED lamps. They have an efficiency of up to 90%. it slows down growth and contributes to the thickening of the stem.

Of course, in the best case, you need to prevent pulling seedlings, but if it really happened, then there are several options to deal with this problem.

Illumination is of no small importance for the development of seedlings. The farther your seedlings are from the light source, the more they stretch. And the closer your seedlings stand on the windowsill, the more it stretches. Do not worry if the neighbors have seedlings of 10-15 cm, and your tomatoes have just sprouted. There's still a month and a half to go. During this time, you can grow a healthy strong seedlings. After all, you probably planted early ripe varieties.

There may be the following reasons: little light and a lot of heat. Most likely your seedlings are standing in warm room on the windowsill. And under the windowsill there is a radiator battery, from which it's warm. With an excess of heat, the seedlings will grow faster upwards, and with a lack of light, this growth will be unhealthy - the sprouts will be thin, pale and weak. This can also happen if the plants are planted very close to each other. Therefore, seedlings must either be planted less often, or thinned out on time, leaving the strongest plants. Keep in a place where it is light, but not very warm. If necessary, illuminate with fluorescent lamps.​

Tomato is a fairly resistant crop, and domestic gardeners grow it almost everywhere in the country. One of the key stages of growing a tomato in a garden or greenhouse is the need to know and understand the diseases that can befall them. In addition, not only tomato leaves will suffer, but the whole plant, and later the entire tomato plantation.

What to do if your tomatoes are exposed to direct sunlight? First of all, make sure that you are dealing with sunburn, it is possible when examining plants, if white spots are visible on the leaves in some places or everywhere, these are certainly traces of a burn. This can happen if, for example, you put seedlings in a container on a windowsill that is illuminated by direct sunlight. Another one alternative cause- the seedlings were transplanted into the open ground, and the plant received stress (from a slightly shaded place to a well-lit open area).

What to do in the situation when the leaves turn white on the tomatoes?

Try to gradually "accustom" tomato seedlings to bright light. To do this, place a container with rooted shoots of this crop in a sunny place for a short time. When the time for planting tomatoes in open ground is approaching, it is recommended to expose the container with seedlings to the street every day. A few hours a day is enough for the greens to begin to get used to the bright sunlight. Only after the implementation of such procedures can you safely engage in planting seedlings in the garden.

Video “Tomato seedling problems”

From the video you will learn about the most common problems of tomato seedlings.

The misfortune of adult plants

Very often, a lack of fertilizer or improper care of a vegetable crop can lead to a low yield of your tomatoes. But if you notice that their leaves turn white, it is advisable to immediately try to find out the cause. Most likely, such a problem arose not because of the provision of illiterate care for tomato seedlings, but because of the invasion dangerous pests or the occurrence of serious illnesses. Before buying store-bought insecticides, you need to find out what is the reason for the whiteness of the leaves on tomato seedlings.

brown spot

If most tomato diseases have whitened leaves in a tomato among the key symptoms, then brown spot suggests a number of problems. Moreover, tomatoes grown in greenhouses are most susceptible to this disease.

What are the symptoms of a disease called brown spotting:

  • the inside of the leaf plate is covered with white fluff;
  • over time, the plaque changes its color, characteristic dark brown shades appear;
  • on the front of the tomato leaf, you can see slight yellow spots;
  • as a rule, the development of the disease can be stopped in the early stages, but if nothing is done, the leaves of the tomatoes curl over time, and the plant itself dies sooner or later.

What tomatoes lack when it comes to prevention is regular ventilation, as well as lowering the level of humidity. Thus, you can prevent serious consequences from this kind of disease.

white rot

This disease affects not only the leaves of the tomato, but also the stems of the plant. Gradually, white spots appear on the vegetative part of tomato seedlings, and the stems soften, a kind of mucous membrane appears on them. It is necessary to treat the plant urgently, otherwise it will simply wither. What is specifically recommended?

First of all, it is desirable to eliminate the infected parts of the plants. Then it is recommended to treat the places of cuts with chalk, coal, potassium permanganate or a solution of copper sulphate. Bordeaux liquid can be used as a universal remedy for such problems. Experienced farmers spray tomato seedlings with it.

powdery mildew

If the tomatoes have light leaves, it is quite possible that the reason lies in powdery mildew, that is, in the invasion of marsupials. How to recognize this kind of disease? On the lower part of the leaf plate, a gray coating appears and white shades. At the same time, characteristic yellow spots can be seen on the upper side. As a result, the leaves simply begin to dry out if the plant is not cured in advance.

It is noteworthy that it is quite difficult to defeat him, it is much easier to resort to basic preventive measures. So, high humidity and generally differences in moisture levels - optimal microclimate for powdery mildew, it is recommended to treat plants with a special preparation during such periods.

Septoria

This is fungal disease, dangerous enough for tomato seedlings. Yellowish-brown spots spread along the leaves of a vegetable crop.
