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 seedlings tomatoes

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 cup 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 it appeared root system, 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 become pale green color, then it's time to feed 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 with a solution 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 beneficial 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, red- purple hue, on the lower leaves chlorosis - 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.

Problems when growing seedlings: seeds do not germinate, do not shed their shells, stretch out, the color of the leaves changes

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 base 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.

beneficial to 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. Shouldn't be stuffed a large number of tomato in one box. Better smaller bushes, but healthy and strong. 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, which 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 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.

poor drainage;

Elongated pale seedlings

When the first shoots from large seeds appear, gardeners often quickly move on to the next stage: remove the film, lower the temperature, increase watering. This inhibits the development of the remaining seeds, preventing them from germinating.

• Several reasons:
• Cold, oversaturated soil can cause seeds to rot, and as a result, seedlings will not appear. Therefore, drainage and holes in the tank for ventilation are necessary.​
• and are indispensable in the kitchen, they are recommended to be consumed as often as possible. From these vegetables you can cook a huge number of dishes, and all of them will be very tasty and healthy. Of course, it is better to grow tomatoes yourself than to buy vegetables of unknown origin in the market or in the store.​

Uneven seedlings

Before planting tomato seedlings in a greenhouse or open ground.

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 wrong temperature regime 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 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

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 the temperature 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 you should pour out one bag of rotten woody leaves and immediately loosen. 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

​Jacob Mittlider came up with an amazing solution to prevent seedlings from stretching out: regular leaf trimming. Tomato seedlings are thus introduced into a state of shock. As soon as the tomato leaves come into contact with a neighboring plant, you need to immediately trim one or two lower leaves. Having experienced a shock, a plant in a week

The temperature should be twenty-five degrees. Sometimes tomato seedlings change color and become pale green. This means that tomatoes

This may happen due to

When the tomato seedlings are stretched out, the stems weaken, become thin and appear bad smell from tomato. Most people immediately throw out tomato seedlings and buy another, however, do not rush, there is a way to save young plant. What needs to be done so that the seedlings do not stretch out?

Lodging of seeds

Very often on the leaves of tomatoes that grow in greenhouses and in the open field appear white, yellow or brown spots. They arise as a result improper care, errors in fertilizer if pests or diseases attacked. Why do tomatoes get sick and how to determine the causes of spots on tomato leaves, how to deal with this phenomenon?

Tomato seedlings can change color due to disease

White spots on tomato leaves

They can point to various reasons. Therefore, it is important to carefully examine the seedlings on the spot, to determine why and what factors contribute to the development of the disease. Small, round, white spots on tomato leaves quickly merge with each other and are accompanied by a white, powdery coating, indicating seedlings affected by powdery mildew. This fungal disease affects the leaves at the bottom of the plant, but quickly moves to the top. A white crumbly coating also appears on the stems, petioles. Powdery mildew is favored by high temperatures and high humidity.

powdery mildew

Powdery mildew is a fairly common but very serious plant disease. It can be easily recognized and difficult to confuse with other diseases. The disease is characterized by a symptom - a white powdery coating, which covers the stems, buds, flowers, the whole plant. Initially, the plaque is small and easy to remove by rubbing with your finger. It spreads rapidly, densely covering all parts of the plant. The plaque is very characteristic, it looks as if someone sprinkled the stem and the whole plant with flour. Affected parts turn brown, blacken, and then die off.

Powdery mildew - a fungal disease of tomatoes

How to deal with white mold

Having noticed the first signs, it is necessary to spray against the disease. For tomato seedlings growing on a personal plot, the use of chemical pesticides is usually avoided and Timorex Gold 24 EC based on a natural extract is used to control tomato powdery mildew. tea tree and approved for use in organic agriculture. Against powdery mildew, the drug is used in an amount of 5-10 ml per liter of water. Sprayed on 10 m² of seedlings. Spraying is carried out four times with an interval of 7-10 days. Good results obtained by alternating Timorex Gold with the fungicide Topsin M 500 SC.

Necrotic spots of white color

Whitish, necrotic spots can indicate a much more dangerous disease called bacterial tomato canker. Symptoms of the disease:

• leaf curling;
• drying of tomato leaves;
• partial wilting on one side.

Gradually, yellow-brown spots are added to the whitish spots, and the whole plant begins to weaken. The stem and petioles turn white and brown or almost black stripes appear on them. In the event of such a disease, infected seedlings must be completely removed, burned along with the roots. The remaining seedlings are treated with a preparation containing copper, such as Miedzian 50 WP.

Spraying is repeated every 7 days. If tomato seedlings are planted in a greenhouse, reduce humidity and disinfect all tools. And so that bacterial cancer does not hit the tomatoes again, it is better to refuse to grow tomatoes in this place for 3-5 years.

Tomato bacterial canker first manifests as leaf curl

food for pests

Very often white spots are the result of feeding pests. If on the upper surface of the leaf, clusters of small, white, round spots form along the edges: a tomato moth (miner fly) has settled here. It is her larvae that feed on juicy and soft greens. As a result, the leaves form narrow corridors, called moves (mines). As the larvae grow, the number and size of the whitish shafts increases. The leaves are severely damaged, die, and fall off the plant. Mospilan 20 SP is used to control tomato leaf miner. A package of 2.4 g is dissolved in 6 liters of water. Repeat spraying after 7-10 days. During the growing season, only 2 sprays are made.

voracious thrips

White spots on seedlings can be the result of feeding one of two types of thrips. Random uneven whitish spots that change color to beige as the seedlings grow and age, indicate the presence of a pest - western flower thrips. Around the spots, pest excrement is also visible in the form of black, shiny and slightly convex dots.

Quite similar silver-white spots along the main veins of tomato leaves, which eventually cover the entire surface of the leaf, are the result of greenhouse thrips.

This is why infected leaves eventually turn yellow and die. To control thrips, as in fly miners, Mospilan 20 SP is used. The natural preparation Agricola will help to avoid chemical pesticides in the fight against thrips. The concentrate is dissolved in a dose of 40 ml of the drug per 10 liters of water.

Thrips leave small white spots on tomatoes

Sunburn

If the temperature is too high and the sun's rays are very strong, young tomato seedlings may get sunburn. It appears as white spots that do not stain. There are no drugs for this disease, and it is difficult to help a diseased plant, burnt and whitened leaves are not restored. Even if the leaf turns white only by half, and the stem remains green, the seedlings will be pale and lag behind healthy plants in development.

Why are tomato seedlings sometimes covered with lutrasil in the greenhouse and in the open field? This measure helps not hardened young plants to survive during the hours of especially active sun.

That is why, when growing seedlings from the first days of life of tomato seedlings, it is recommended to harden them and regularly take them out to the sun so that they adapt and get used to ultraviolet rays and sunlight. Increase the time spent in the sun from day to day and then you will not have to resort to additional measures protection and worry about whitened seedling leaves.

Leaves turn white at tomato seedlings - what kind of misfortune? Experienced gardeners are convinced that you need to try hard to ruin tomato seedlings. They think it's strong hardy plant, not requiring special care. Tomatoes almost always please with a good harvest, but the question is, will beginners be able to achieve such a result?
As practice shows, not everyone undertakes to plant tomatoes. This means that in reality everything is not so simple. Seedlings are susceptible to diseases and pests. Adverse weather(rain or drought) can also kill the plant.
A lot of questions are caused by such a phenomenon as a change in the color and structure of the leaves of seedlings - they curl and. The appearance of white spots on the leaf plates may indicate the most different problems, and the sooner the cause is established, the greater the chance of saving tomatoes.

Sunburn on young tomatoes

Why do the leaves of tomatoes turn white and dry after planting in the ground? Most often this problem affects young plants. For example, all foliage turned white, and only the stem remained green. Some tops can also turn white - only the leaves of the seedlings that have appeared.
If these signs are present, it can be concluded that the seedlings are affected by sunburn.
Plants could get it under certain circumstances:

• unprepared seedlings were exposed to the open sun;
• tomatoes were transferred from the premises and immediately planted in the ground or in a greenhouse.

What to do?

• Seedlings need to be accustomed to the sun from the moment the young shoots appear. Containers with plants should be placed by the window to most during the day the sun was shining on them.
• If there is little sun (“northern” windows, cloudy spring), tomatoes are accustomed to the sun gradually. Before planting in the ground, seedlings should be exposed to the sun for several hours. Every day you need to increase the time spent on the street.
• If unaccustomed plants are planted in a greenhouse, then it is necessary to cover them with lutrasil, a non-woven fibrous material. Ordinary beds it is also recommended to cover with this material placed on the arcs.

If there is a greenhouse,. The plant will develop there quickly and without problems. Tomatoes will get used to the sun's rays and at the same time adapt to growing outdoors.

At first, the greenhouse must be kept covered. You can open it only for watering and airing tomatoes. As the temperature rises, the ventilation time should be increased.

If the foliage is already affected by a burn, there is no way to return the green color to the whitened leaves. However, you can still try to save the plant. In the evening, after sunset, the leaves are treated with "Epin" - a biostimulant. Thanks to this tool, the tomato will cope with stress. Processing is carried out three times with an interval of 7 days.

The affected plant will develop more slowly.

Problems in adult seedlings

Often the leaves turn white due to disease. The disease is evidenced not only by white spots, but also by other signs.

brown spot

Happens at the beginning of fruiting. Suffer from the disease, as a rule, tomatoes grown in a greenhouse.

Symptoms:

• the leaf plate from below was covered with a white "fluff";
• plaque gradually acquires a dark brown color;
• on top of the leaves appear yellow indistinct spots;
• if the plant is sick for a long time, the leaves curl and dry.

This is one of the reasons why tomato leaves turn white and dry.

The disease progresses rapidly and spreads with high humidity and air temperature. The best prevention is frequent ventilation of the greenhouse and a decrease in humidity.

At the first sign, tomatoes need to be processed Bordeaux mixture- solution blue vitriol in milk of lime. The procedure is repeated four times with an interval of 10 days.

white rot

This is fungal disease that affects stems and fruits.

Symptoms:

• plant tissues become soft and slimy;
• a white mycelium appears on the root neck, stem and at the base of the leaf plates;
• the tomato gradually withers and dies.

The disease spreads rapidly at low temperatures and high humidity.

What will help?

• Mode setting.
• Partial or complete elimination of diseased tomatoes.
• Treatment of the cut site with crushed chalk, coal, potassium permanganate solution or copper sulphate.
• Spraying with Bordeaux mixture.

powdery mildew

The causative agent of the disease is marsupial fungus.

Symptoms:

• grayish bloom and white spots on the lower part of the foliage;
• appear on top of the leaves;
• leaves burn out and dry

Why do tomato seedlings turn white leaves? If there is a gray-white coating from below, and yellowness from above, then the culprit of the disease is precisely powdery mildew. The disease progresses with sudden changes in humidity. Tomatoes are very difficult to treat. It is easier to prevent the problem - with frequent rains, spray the seedlings with "Tsineb" - an effective fungicide.

What will help?

• Cutting and burning diseased parts of a tomato.
• Treatment with a solution of "Tsineb" or "Trichodermin" (fungicide).

Septoria

Another name for the disease is white spotting. This is a fungal disease.

Symptoms:

• at the beginning of the disease - brown marks on the bottom of the leaves;
• growth of brown dots into white spots with a yellow frame;
• the appearance of dark dots on the spots;
• the spread of the disease to young tops.

What to do?

The affected parts must be cut off. The entire bush is treated with Fitosporin, a new generation biofungicide.

late blight

Another disease that threatens tomatoes. Usually, it first affects the potato, and then goes to the tomato.

Symptoms:

• foliage and branches become covered with brownish spots;
• from below sheet plate- white spots in the form of plaque;
• brown spots are found under the skin of the fetus;
• they grow rapidly and cover the entire fruit;
• the tomato becomes hard, and then quickly becomes sour.

What to do?

The affected parts of the bush must be removed, the plant itself must be treated with a Bordeaux mixture. Fruits taken from diseased bushes should be placed for a couple of minutes in hot water(from 60 degrees). This is necessary for disinfection, even if there are no visible stains.

So, why do tomatoes turn white leaves? This can happen for several reasons. The culprit of the problem is often a banal sunburn. This happens after or primer.

Various threats are fungal diseases, the most dangerous of which is powdery mildew. To prevent disease, it is necessary to maintain optimal humidity in a greenhouse or greenhouse, regularly ventilate and periodically treat the bushes with fungicides. If infection has occurred, the affected parts are cut off, and the bushes themselves are sprayed with the same fungicide.

Why tomatoes grow poorly, why tomato seedlings are pale and thin, what to do in such a case - such questions are often of interest to novice gardeners. To save the crop, you must first determine the reason why the stems stretched out and the leaves turned pale green.

After changing color, the plant is put in its original place. To prevent nitrogen deficiency, do not forget to feed the tomatoes in time with special fertilizers.

If tomato seedlings have become elongated, thin and pale green, the reasons for this may be the following:

1. Lack of nitrogen compounds in the soil. In this case, you need to feed the tomatoes with a solution of urea. The solution is prepared in the ratio of 1 tbsp. l. for 10 liters of water. After abundant watering, the seedlings are placed in a cool place where the temperature is kept at + 8-10 ° C. Do not water until the soil is completely dry. This will slow down the growth of the plants a little, but after a few days the tomatoes will become brighter and greener. After changing color, the plant is put in its original place. To prevent nitrogen deficiency, do not forget to feed the tomatoes in time with special fertilizers.
2. Insufficient illumination. The sprouts receive little light when they are densely planted in a container and there is not enough daylight due to a short sunny day, cloudy weather or an overabundance of shade. To avoid this problem, it is enough to move the plants to a brighter place. Additionally, for lighting in the dark, you can use fluorescent lamps, which must be hung not only from above, but also on the sides, so that the lighting of the sprouts is more comprehensive. It is also advisable to put the plants to the windows that face the south side: the amount of sunlight will increase. To avoid dense planting, plant seeds must be placed at a distance of 4-5 cm from each other.
3. Too active care. Too frequent and abundant watering, as well as an excess of fertilizers, lead to seedlings stretching. If there is a large amount of nitrogen in the soil, the leaves of the seedlings begin to curl inward. In such a situation, it is necessary to balance top dressing and water less frequently.
4. Temperature violation. If the temperature fluctuates constantly, the sprouts begin to stretch and brighten. In this case, it is necessary to approach optimal temperature for sprouts; after a while it is worth lowering it by + 4-5 ° C, so that the seedlings stop reaching for the light, and direct their forces to strengthen the root system.

To avoid this problem, it is necessary to provide the sprouts with a temperature of + 15 ... + 18 ° С. To stimulate development, you can increase the temperature to + 25 ° C. As soon as the sprouts have reached the desired height, the temperature must be lowered again. If this condition is observed, then the seedlings will become lush, with a slightly purple thick stem and dark green foliage.

Too long and thin stem

Long seedlings can be planted in a deeper container. If before landing on permanent place there is still a lot of time left, the long stem can be reduced in another way. The sprout is slightly dried so that it fades a little, then it is laid in a spiral, sprinkling each row with soil. After that, lightly compact the earth and shed well with water.

To avoid this problem, it is necessary to provide the sprouts with a temperature of + 15 ... + 18 ° С

If by the time of transplanting the sprouts have become too elongated, then seedlings can be planted in the following ways:

1. Bury the plants in the soil.
2. A few weeks before planting, the elongated seedlings should be cut just above 5 or 6 leaves.

Long seedlings can be planted in a deeper container

If you strictly observe the correct temperature and light conditions, feed the tomatoes with fertilizers in time, then the plants will not have problems with growth and you will certainly get good harvest tomatoes.
