Tomato seedlings are light green what to do. Diseases of adult plants in the greenhouse and open field

Growing, it is important to create as much as possible favorable conditions for its growth and development, since otherwise the gardener will inevitably face various kinds of troubles. So, for example, it often happens that the leaves of tomato seedlings seem to turn white for no reason. What can this condition indicate, what contributes to its appearance and how to restore a healthy appearance to seedlings?

Sunburn

Spots of white, localized on the leaves of tomato seedlings, as well as a whitish shade between the veins of the leaves, most often appear due to the plant receiving sunburn. Perhaps the seedlings were left under the direct rays of the sun, or the tomatoes were taken out onto the balcony, where they first got unsuccessfully acquainted with the sun.

There is also another type of sunburn, the cause of which is the splashing of water on the foliage of seedlings during irrigation. If you do not gradually accustom tomato seedlings to ultraviolet radiation, then it is possible that plants will get sunburn even after transplanting into a greenhouse. At the same time, at least the leaves will turn white and soon fall off, as a maximum, the seedlings will die.

Even if a part of a seedling leaf has received a burn, then this will not pass without a trace for the plant: the affected area will not take part in photosynthesis, and the plant itself will be forced to spend a lot of energy on a full recovery. At the same time, interestingly, the first symptoms of a sunburn will manifest themselves only after a couple of days. In order to avoid getting a sunburn, it is necessary to accustom the seedlings to the sun gradually, taking them out to the balcony for 10-15 minutes and gradually increasing this period of time.

Soil salinization

Another reason why on the leaves of tomato seedlings may appear white coating is increased soil salinity. This condition of the soil can be diagnosed visually.

To do this, you need to carefully look at the soil; when salinized, a yellowish coating in the form of grains can be found on its surface. In order to save seedlings, it is necessary to remove upper layer soil, replacing it with a new fertile soil, then water exclusively with filtered water, which should flush the soil.

What to do

If the tomato seedlings have turned white due to exposure to the sun, then you should not try to return the leaves to their former green color. However, there is a set of measures that allow tomato seedlings to recover and gain green mass.

So, for example, in the evening, at sunset, it is recommended to treat seedlings with Espin or another drug that has a similar effect. This manipulation should be carried out once a week for three weeks. It is also necessary to provide the plant with the proper amount nutrients. It should be borne in mind that tomato seedlings that have survived a sunburn will begin to bear fruit later than its healthy species.

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, we need to lower it, we 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. 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 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 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 off the lower part (long root) and plant it 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 did not grow seedlings correctly: the soil is very poor in nutrients, there is little light, and the room is excessively warm. 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. Can be in sunny days take out to the glazed balcony. 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 in the resulting solution mineral fertilizers do not contribute.​​Everyone who wants to enjoy the taste of self-picked 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

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.

Tomatoes still have a lot of time. they will increase theirs. I experimented this year too. I have half of the tomato seedlings that came out like this. I planted. but I was already mentally prepared to throw them out. they stayed for 10 days. and then they started chasing good seedlings. haven’t caught up yet, but I don’t call them slugs anymore

Good growth of tomato seedlings is observed when it is fed 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, etc., as well as wood ash. From organic dressings apply - chicken manure, mullein manure, liquid fertilizers"Ideal", "Chippolino", etc.

​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.

Elongated tomato seedlings lend themselves perfectly to picking! Since the tomatoes are planted during the picking process, which we do, we put the long stems of the tomatoes into the ground and a new powerful root system grows on them, which is very good for the subsequent growth of tomatoes.

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. Try to land - suddenly everything will work out for you. If they don’t take root, buy on the market.​

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. I don’t remember the name of the fertilizer, ask in stores where the seeds are sold, tell me what you need for seedlings so that they don’t stretch out. glazed balcony and it is warm enough to take out seedlings. a balcony door do not close the room. You still need not to chase early varieties and grow seedlings to suit your climate.​ ​Of course the best place for growing seedlings, these are windows to the south, because it is necessary for seedlings to provide maximum daylight hours, plus add lighting with a lamp after dark.

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:

Feride 333

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 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 happened, then there are several options to deal with this problem.

I think that you did not mean fertilizers, but retardants that inhibit plant growth, for example, "Athlete". - over a year ago

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.

4. If stretched out, immediately pour in the earth to hide the "long trunks", it is advisable to put it on the windowsill (in a bright place). it is better to grow seedlings at temperatures below room temperature (it also climbs from heat)
5. The first option involves drowning the stem into the ground, if the seedlings grow on the street, then the earth has not yet warmed up much, so it is better to plant the plant on a slope.

Sooosolnechnaya

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 most strong plants. Keep in a place where it is light, but not very warm. If necessary, illuminate with fluorescent lamps.​

Problems with tomato seedlings do not occur often. As a rule, young tomatoes cause the least trouble to the gardener: they grow well, take root easily, endure painlessly - it would seem, what more could you want?

But sometimes even with such an unpretentious culture as a tomato, trouble can happen. The seedlings are stretched, turn yellow, the tips of the leaves dry up, white spots appear.

Let's take a look at the most frequent problems tomato seedlings, learn how to avoid or eliminate them.

The most common reason for pulling tomatoes is a lack of light. The window sill is not rubber, but you always want to plant more varieties, and even with a margin. This is how tomatoes grow in cramped boxes, blocking each other's access to light. Here they are stretching. The solution to this problem is obvious - do not be greedy, do not plant too much, place the seedlings on the windowsill freely and, if possible, use the backlight.

Tomato seedlings are pulled out if the “tropical paradise” is also broken on the windowsill. In bright sunlight (or artificial) light, the temperature should be no higher than + 25-28 ° C. And on a cloudy day, even lower - + 18-20 ° С. Otherwise, the so-called "greenhouse syndrome" cannot be avoided - the effeminacy of seedlings, their sensitivity to temperature extremes. In seedlings spoiled with excess heat, the stems become thin and the leaves brittle.

Excessive watering and top dressing can also cause tomato seedlings to stretch, so tomato seedlings should be watered only when the soil is completely dry. With, too, do not need to be too zealous - fertilize only if necessary. For example, stunting, discoloration of leaves, etc.

Problem two: tomato seedlings turn pale, turn yellow, the leaves dry up and fall off

Basically, tomato seedlings turn yellow due to insufficient lighting and excessive soil dampness. Remember that the ground tomato seedlings does not need to be constantly kept moist. Water the seedlings sparingly, allowing the soil to dry out. Keep cups with seedlings on the brightest window sill, and if the weather allows, take them out to the balcony to "bask in the sun."

Is it possible to save already affected plants? You can, if you transplant them into fresh soil. The roots of each seedling must be freed from the old earth, make sure that they are white and healthy (if the roots are yellow, black or rotten, the seedlings can no longer be saved) and transplanted into light, slightly moist soil. Pour 20 ml under each plant. pink solution of potassium permanganate and put the cups on a sunny window. It may happen that during the transplantation the roots are damaged and the seedlings wither in the light. Then you should shade them for the first time. But after rooting, good lighting and infrequent watering are mandatory and the necessary conditions for the further development of seedlings.

If you follow the rules of watering, and there is enough light for your seedlings, but it still turns yellow or turns pale, you should pay attention to the nature of the change in leaf color. Perhaps the plant is experiencing, which needs to be replenished.

Problem three: the tips of the leaves dry up in tomato seedlings

The reasons for the drying of the edges of the sheet, as usual, are a whole list.

First, take a look at indoor plants or seedlings of other crops - do they have something similar? If the leaves are drying on everyone, the cause may be excessively dry indoor air (heating is doing its best). In this case, it is recommended to place wide containers with water next to the seedlings.

Secondly, check for white or yellowish spots on the surface of the soil - efflorescence. When the soil is “oversalted”, the roots of the plants begin to “work in reverse”, that is, they draw nutrients and water from the stems and leaves. As a result, the tips of the leaves become thinner and dry. The earth is salted due to excess fertilizer or due to watering with hard water. What to do? Carefully remove the top layer of earth and add fresh soil. It is good to shed the seedlings with soft water (rain, filtered, melted water) and forget about top dressing for at least two weeks.

Third possible reason drying of the tips of tomato leaves in a lack of potassium. This usually happens when hyperacidity soil. Potassium deficiency is well replenished with such top dressings as:

• Ash infusion. It is prepared as follows: a handful of ash per liter of boiling water is infused until completely cooled, and then diluted with water in a ratio of 1:5.
• infusion banana peel: 2 tbsp powder from dry banana skins insist in three liters of water during the day.

For a week you need to do three potash top dressing.

Problem four: spots on tomato seedlings

Often white, transparent spots on tomato seedlings occur due to sunburn. Seedlings need sunlight, but direct sunlight can easily burn the leaves. This sometimes happens when the seedlings are "unaccustomed" to the sun (during prolonged cloudy weather, for example). With an aggressive sun, you need to shade the plants with newspapers, and spray the affected leaves with Epin.

Dirty white spots with a dark border on the leaves of tomatoes mean that your seedlings are sick with septoria (white spotting). This is fungal disease, which is carried along with the soil and develops when high temperature or humidity. Affected plants are best removed.

Fungal diseases are difficult to cure, it is better not to allow them. To do this, warm (or freeze) seedling soil before planting seeds. Or carry out preventive treatment of the soil with antifungal drugs.

Problem five: black leg of tomato seedlings

black leg (or root rot) is also a fungal disease that affects young seedlings. It is characterized by a darkening of the stem in the lower part and the formation of a "peregrine". Diseased plants wither, lie down, their roots rot.

Again, the black leg is one of those diseases, from the occurrence of which it is better to make sure in advance. To do this, at the stage you need to add wood ash to the ground for seedlings, and when caring for seedlings, avoid waterlogging the soil and too high temperatures.

If trouble nevertheless happened and several young seedlings in the box suffered, you can try to save the rest by transplanting them into another soil with the addition of calcined sand and ash. After transplantation, it is recommended to spray the plants with "Fundazol" and stop watering until the earth is completely dry.

Read more about the prevention and protection of seedlings from the black leg.

When something is wrong with seedlings or adult plants of tomatoes (tomatoes), the summer resident is inclined to blame diseases and pests for all troubles. However, in some cases, a stunted appearance, unusual leaf color and dry edges are symptoms of a lack of certain nutrients in the soil.

Therefore, before starting a holy war for the crop with microbes and bugs, we suggest that you familiarize yourself with the reference table “Nutritional Deficiencies in Tomatoes”. For clarity, the table is provided with photographs, as well as detailed descriptions external signs plant starvation.

Reference table "Nutritional deficiencies in tomatoes"

It is important to know that the deficiency of elements such as nitrogen, phosphorus, magnesium, potassium and zinc first manifests itself on the formed lower leaves of the bush, and the lack of all other trace elements is most noticeable on young apical leaves and escapes.

If you do not want to use mineral fertilizers when growing tomatoes, then take note:

• as nitrogen supplements, you can use mullein infusion, infusion chicken manure, granulated biohumus and compost;
• to provide plants with potassium and phosphorus, root and foliar top dressing with wood ash, as well as fertilizers based on humates, can be carried out;
• to increase the amount of calcium in the soil, crushed eggshells must be added to the ground;
• if there is a shortage of copper, you can stick a piece of copper wire next to the tomato bush.

We wish you success and great harvests!
