Why do leaves dry up on tomato seedlings. Why do the leaves of tomato seedlings dry and then fall off? Causes of salinity of the land for seedlings

In any suburban area grows such a culture as a tomato. Tomatoes are usually grown in seedlings. And this process is very time-consuming, requiring knowledge and accuracy. After all, even a recently sprouted sprout is subject to a lot of diseases and, if certain rules are not followed, an improperly created microclimate, it can die. The question of why the leaves of tomato seedlings dry is of interest to many vegetable growers, especially beginners. This article will consider the main reasons for this phenomenon and give recommendations for improving the condition of the plant.

Each summer resident should understand why the leaves on tomato seedlings dry up in order to prevent such a situation, as well as to eliminate it in a timely manner. Otherwise, there is a chance to ruin the future crop. An attempt to re-sow the seeds may fail, because there simply is not enough time. Yes, and there is a risk of making a mistake again.

Causes of fall of all leaves

The main indicator of tomato health is green mass.

Usually, an experienced farmer immediately sees why tomato seedlings dry, and, having taken appropriate measures, quickly corrects the situation. But as for beginners, they rarely manage to improve the condition of seedlings. Therefore, before engaging in seed germination, it is worthwhile to carefully study the features of tomato cultivation, as well as the problems that may arise in the process.

That's why the leaves fall off the tomato seedlings grown on the windowsill:


Causes of drying of the lower leaves

Often, the tomato seedlings dry the leaves located at the bottom of the plant. This is typical for pale seedlings. Lower ones first. Then they dry up and fall off. This situation raises many questions. Inexperienced summer residents cannot understand the reason for this state of the plant. In fact, everything is simple.

Why the lower leaves of tomato seedlings dry out is described below:

  1. Lack of nitrogen. At the same time, the bush becomes sluggish, the foliage becomes faded. New leaves are inconspicuous and small.
  2. Potassium deficiency. The lower leaves with a lack of this element turn yellow and dry.
  3. Excess moisture as a result of improper irrigation.
  4. Lack of lighting.

Thus, the deficiency of certain elements is the main reason why the lower leaves of tomato seedlings fall most often. There is no need to worry too much here. The situation is quite fixable.

Causes of drying of the tips of the leaves

Sometimes gardeners observe the following situation: at the tomato seedlings, the tips of the leaves dry, turn yellow and curl. And there are many reasons for that. Consider the most common.

Why the tips of the leaves of tomato seedlings dry is described below:

  • Dry air in the house. To do this, pay attention to the condition of other plants. Perhaps they also dry out the tips of the leaves.
  • Salted soil.
  • Lack of an element such as potassium. This is usually characteristic of the soil, which is characterized by high acidity.

Thus, there are many reasons why the lower leaves of tomato seedlings dry out. And it is important to correctly determine why such a situation with seedlings occurred.

Other reasons for the poor condition of tomato seedlings

The temperature is too high - that's why the leaves of the tomato seedlings fall on the window. Probably the crate of sprouts is near a functioning battery. Then the container will need to be moved to another location. You can also try to isolate the container from the heat source with plywood sheets.

Sometimes, after picking, the farmer observes that the leaves begin to dry out. Most likely, the roots were damaged during the transplant procedure. What to do in this case, how to save tomato seedlings and bring them back to life? There is an exit. It is necessary to spray the plant with a weak solution of a mineral complex fertilizer.

How to save tomato seedlings?

When the leaves of tomato seedlings dry, every vegetable grower should know what to do. First, you need to determine the root cause of this condition. And already, proceeding from this, try to improve the situation.

Experts give such advice:


It is important to note that it is extremely difficult to fight fungal diseases, it is much easier to carry out prevention.

To do this, it is desirable to collect seeds for future seedlings from healthy, adult shrubs. It is even better to buy seed in a specialized store. Before sowing, it is good to pickle the seeds with a weak solution of potassium permanganate. The container for seedlings should be disinfected. All instruments too. The soil should be of high quality, in which there is no infection.

Potassium deficiency is easily replenished by irrigating the soil with banana peel infusion or ash infusion. Such top dressing is done three times a week. In order to avoid a problem with the fact that the lower leaves of the tomato seedlings dry, one must be able to apply fertilizers correctly and on time.

  1. With a shortage of sunlight, seedlings should be moved to a more lit place. You can also create artificial lighting by installing a fluorescent lamp.

When the leaves of tomato seedlings fall, inexperienced vegetable growers do not know what to do, which is why they often lose their crops, although it is quite possible to save the plant. For example, try transplanting sprouts into fresh soil. In any case, such a procedure will not harm. To perform this operation from the roots, you need to carefully remove the old earth. Roots should be carefully examined. If they turned yellow, turned black, rotted, you will have to throw out such seedlings.

If they are in good condition, continue transplanting. The soil should be light, with good aeration. It is advisable to pour a spoonful of manganese solution under each young growth.
Glasses with sprouts are placed in a sunny place. But, if tomato seedlings dry after transplantation, it must be placed in the shade for a while. Probably, the roots were damaged during the procedure. It is important to give them time to get stronger, take root. And then put it in a sunny place.

A situation often arises: a summer resident works tirelessly on seedlings, but even with sufficient watering, proper feeding, tomato seedlings still disappear - few people know what to do in this case. Why are the sprouts in such a state if all the rules for growing are followed? It is important to check that the soil is not infected with fungal infections, viruses and other pathogens. Probably needs a transplant into new soil. You can try to defeat the infection by spraying with special industrial solutions against pests and fungi.

Conclusions about the poor condition of seedlings

Thus, it is easy to judge the condition of the bushes by the green mass. Often summer residents are faced with the fact that the lower leaves of tomato seedlings fall off, the sprouts wither, wither, fade, the leaves become stained. All this suggests that the rules of cultivation are not followed, the microclimate necessary for the plant has not been created, or there is a fungal infection, a virus. Therefore, you need to be able to determine the root cause and know, be able to restore its vitality.

Tomato culture is very ancient. There is evidence that they were grown back in the 8th century AD, the ancient Aztecs did it. Only hundreds of years later, vegetables came to Europe, while the ancestors considered tomatoes to be a big berry.

What do tomato seedlings need to grow?

Beginners in country affairs often make many mistakes, which lead to a negative result. In order for seedlings to grow from year to year and not disappoint, you need to gain experience and knowledge. It is not enough to plant seeds in the ground from the garden to get seedlings. It is necessary to observe all the methods of agricultural technology from the first stages.

Things to consider:

  • soil nutrition - it gives strength and immunity to future seedlings, which means that it is less affected by diseases, that is, tomatoes will not turn yellow, wither, blacken;
  • light - since the school biology course, we all know that plants need light, otherwise they simply die. This is one of the main rules. There is not enough light - lamps are needed so that the lighting is at least 10-12 hours a day;
  • watering - even a child knows too. If flowers or garden crops are not watered, then the result will not be long in coming. Water must be settled so that the soil does not accumulate heavy elements. Also, it should not be icy so that the roots are not stressed;
  • top dressing - it’s not enough just to plant the seeds in nutrient soil, as the seedlings will soon take everything from the soil. Then there will be a nutritional deficiency, hence the immunity falls, and the seedlings will start to hurt.

What can be concluded from the above? If you do not know why the leaves of tomato seedlings turn yellow, then it is worth reviewing all agricultural technology and identifying shortcomings. If measures are taken in time, then the seedlings can be easily saved and get a good harvest in the future. Let's take a closer look at everything in the next section.

Causes of yellowing of the leaves of tomato seedlings

Feeding errors

As you already understood, any culture is very sensitive to the nutritional value of the soil. Tomatoes respond well to feeding, they love them. It is especially important to give regular fertilizers to those varieties that grow tall and have a powerful root system. Fertilizers must include a complex of elements in order to fully compensate for the entire deficiency. If some mineral is missing, then problems begin, including yellowing of the leaves of seedlings in tomatoes. But beginners will immediately ask the question, how to understand what exactly the seedlings lack? Everything is pretty simple.

Any problem is better to prevent than to deal with the consequences. Therefore, before the start of the summer season, buy not only elbows for seedlings, seeds, but also immediately different fertilizers, additional lighting.

The main elements that are necessary for tomatoes are potassium, nitrogen, zinc, manganese, iron, copper, phosphorus. They must be in the optimal combination - of course, it is difficult for you to make the perfect top dressing yourself. But a complex preparation is easy to buy at a gardening store. You can also solve the problem when you have already understood which mineral is currently in short supply - fill it with the appropriate fertilizer. There will be a separate section on them. So, how to determine why the leaves of tomato seedlings turn yellow.

Element deficiency:

  • if you notice that the foliage of the seedlings has begun to lose its green pigment, it turns yellow, falls off regularly, and new leaves form small, then most likely the reason is a lack of nitrogen in the soil;
  • if you see that the young leaves on the seedlings begin to curl, the old ones lose their color, yellow spots appear, then this is most often a lack of potassium in the soil;
  • magnesium deficiency may be indicated by yellow color along the veins on the leaves;
  • if the leaves turn yellow at first, then even become white, then this is an iron deficiency;
  • on seedlings you see two types of spots - brown and yellow, then this is a lack of zinc;
  • the following fact can suggest a deficiency of manganese - the leaves turn yellow here and there, often in a checkerboard pattern, moreover, the process starts from the base.

These signs, upon careful examination and observation for several days, can be seen even by a beginner. As soon as you understand which element is in short supply, you need to make up for it with top dressing. As a rule, the situation will quickly begin to change for the better, because we repeat once again that the tomato culture is very responsive to fertilizers. But is it only a lack of fertilizer that can cause a problem when the leaves of tomato seedlings dry. Of course not. Perhaps the reasons are much simpler.

Insufficient lighting

This problem is easy to identify and solve. We all know that where there is a lot of sun, places, moderately humid, all plants - whether cultivated or just weeds, are fragrant. And vice versa. Tomatoes are very photophilous, of course, they can also suffer from sunlight. It is optimal to put seedlings on the southeast window, the east one, or put it next to it, creating a light lacy penumbra.

If the window is south, there is a lot of sun on it, which starts to burn strongly in spring, besides, the region is warm, then the seedlings may begin to turn yellow, because they are hot. In addition, direct rays can burn tender seedlings, especially if they also lack moisture. The easiest way to solve this problem is to remove the boxes of tomatoes to another window or put them next to the table so that there is a light shadow from the curtains, also watch the watering, the soil should not dry out and even more so lag behind the walls of the pot.

But the situation is different - what to do when tomato seedlings turn yellow from lack of light? Make additional lighting.

Lighting lamps:

  • sodium - include an optimal spectrum for seedlings, they help seedlings grow very well. But such lamps require space and are not cheap;
  • phytolamps - ideal for plants in the spectrum, used both in greenhouses and at home, suitable for growing for sale. But this light is also not cheap, and also has a pink color that irritates the eyes. Optimal for those who grow seedlings in a separate room;
  • fluorescent lamps are cheap and quite well suited for small-scale seedling cultivation. The lamps are economical, but they emit little red spectrum, and are also dangerous if they break. Also a minus is a small coverage area;
  • diodes are a very good option, but not cheap. Diodes can be bought in any color, they are economical, safe and durable.

If you have now asked the question, is it not easier to put a simple incandescent lamp over the container, then do not rush to draw conclusions. No - incandescent lamps are extremely unsuitable for seedlings, they do not emit the spectrum it needs, they spend a lot of energy and, moreover, threaten to burn delicate seedlings. Which lamps to choose, you decide. If you plan to deal with seedlings all the time, then it’s better to spend money once, but buy high-quality lighting. If you are a beginner and just trying yourself, then take simple fluorescent lamps.

All lighting can be bought at gardening stores, hardware stores, online stores. In the latter case, make an order in advance, as delivery is often delayed.

Consequences of close planting seedlings

Well, everything here is simple and easy to solve. If you often sowed seedlings, dived after not into separate cups, then it is quite possible that the seedlings are suffering from their own brethren. Its roots are closely intertwined in the ground, which is important to take into account in the future when transplanting, so that there is no injury. A lot of seedlings in the tray also take a lot of food, but we have already told you about the lack of elements. In addition, seedlings shade themselves, and we also just mentioned this.

An excess of plants often leads to an excess of moisture in the soil, then diseases can begin to develop there, and the roots rot. The latter directly affects the leaves - they turn yellow, fall off, the seedlings wither and die. The solution is simple - plant the seedlings more freely, but rather in separate cups with new clean soil.

The soil

Of course, seedlings need very good soil. About the fact that it should be nutritious, you already understood. But that's not all. The earth must pass air well so that oxygen enters the root system, then it will develop well, nourish the entire above-ground part. If the earth is heavy, you can hardly loosen it, then it is better to replace the soil with a new one before it is too late. The mistake could be that you just took the soil from the garden, and it is not suitable for you. It is not enough to just add top dressing to the ground, you also need to add sand, peat or perlite to it for breathability. It also affects the content of excess water.

An important factor is the acidity of the soil. It is tested using litmus paper, which is sold in pharmacies, garden stores or on the Internet. Tomatoes do not like acidic soil, like many crops. Normal pH is 6-6.5. If the soil is acidic, that is, the indicators are much lower than 6, then lime, chalk, fluff, dolomite flour are added, mixed and the indicators are checked again with paper.

If you did not find litmus paper, then you can understand that your soil in the area is acidic by the vegetation that grows wildly on such soils - horsetail, hosts, heather, plantain.

But not only acidic soil has a bad effect on seedlings, but also salty. You can understand that you are using salty soil, and it has a bad effect on seedlings, by the fact that a white or yellow coating appears on the surface of the earth. Seedlings are best transplanted into new soil. If you can not pick up the soil yourself, then just buy ready-made.

Wrong watering

Another most common and easily solved reason. To understand that you are flooding the ground heavily, you can by the fact that your soil almost does not dry out, mold has appeared. Also a clear sign of the bay is the cotyledon leaves of the tomato seedlings turn yellow. From excess moisture, a pathogenic environment begins to develop, which leads to diseases, rotting of the roots. You need to water the seedlings as the soil dries out, every day it should be only slightly moist and well loosened. You can neither pour seedlings, nor, conversely, let it dry out when the soil moves away from the walls of the trays. Water must be defended for a day.

Diseases

Of course, one of the common causes of yellow leaves on fragile seedlings can be diseases.

  • Rot that occurs against the background of excess moisture. The solution is to reduce watering or transfer to new soil. Also keep an eye on room humidity and temperature.
  • Fusarium. It can also occur against the background of excess moisture and in the cold. Adjust watering, temperature. The seedlings are treated with "Fitosporin" twice in a row, after which they take a break of 14 days and repeat the treatment again.
  • Late blight. If the leaves begin to turn yellow and brown spots appear, then immediately spray them with a salt solution - 1/2 tablespoon of salt per liter of water. You can apply a solution of the drug "Trichopolum" in water. 10 tablets per bucket and pour 15 ml of brilliant green here. The same tool can be used to prevent diseases during flowering.

What to do if the leaves of tomato seedlings turn yellow

Let's summarize all of the above. You already know why tomato seedlings turn yellow, you could also understand what to do. We will talk about replenishing the deficiency of one or another element in the last section, but in all other cases everything is quite simple.

  • If you have flooded seedlings, then it is advisable to remove the seedlings from the ground and assess the damage on the roots. Then transplant into a new, well-drained and nutritious composition.
  • Keep the temperature in the room within 23-26 degrees.
  • If you notice yellowing, then you can immediately feed the seedlings with a complex preparation, if you know for sure that the reason is not in acidity, not in the bay.
  • If the earth is acidic, then you will have to transplant it into a new soil, having previously checked it with litmus.
  • If the seedlings began to turn yellow after picking, then shade it and only occasionally water it, let it get stronger.
  • If the seedlings are crowded, then rather divide them, and remember that the light needs to be thought out in advance.

Top dressing for tomato seedlings

Urea

This tool will help to form a good aerial part or simply green seedlings. The thing is that urea contains a lot of nitrogen - more than 45%. They begin to feed her seedlings after germination, then every 14-20 days. After picking, they stand for 10-14 days for seedlings to take root. Sold in stores in the form of white balls. Approximate consumption - 20-30 grams per bucket of warm water.

  • affordable price;
  • high concentration of nitrogen;
  • very fast effect;
  • simplicity and versatility in use;
  • disease prevention;
  • the possibility of using for foliar feeding.
  • nitrogen should not be given to plants during flowering and after, otherwise fruits will not be set;
  • it is important to observe concentration, as seedlings can get burned;
  • slightly acidifies the soil.

Manganese solution

They can make up for the deficiency of manganese in the soil. It is used as a foliar spraying - once every 7-10 days throughout the growing season. The solution should be slightly pinkish.

  • serves as an excellent preventive measure;
  • budget tool;
  • disinfects;
  • can always be used, and also for soil dressing.
  • high concentration can lead to the death of plants.

Ash

One of the oldest and most popular means. Wood ash includes several elements at once - potassium, calcium, magnesium, sodium, phosphorus and others in smaller quantities. The recipe may look like this - a glass of ash is dissolved in a bucket of water, kept for 2 days. You can shed the area and use for spraying.

  • cannot be used as a complete feed, it is better to combine ash with organic matter;
  • the effect of top dressing is quite short, you will have to make it often.

Potassium nitrate

This top dressing contains not only potassium, which is needed by both seedlings and future fruits, but also phosphorus and nitrogen. They feed with saltpeter and seedlings, and bushes in the beds. The norm is 1% solution, top dressing is combined with watering. Dilute 10 grams per bucket of water.

  • well helps to fill the deficiency of elements;
  • can be used throughout the growing season;
  • affordable price;
  • disease prevention.
  • you must strictly observe the concentration and precautions, as you can get poisoning.

Destroy plant debris; To avoid diseases, it is necessary to properly fertilize and water the tomatoes, to ensure the necessary temperature conditions. Proper dressing of seeds before sowing will also give positive results. If you collect the seeds yourself, then choose only healthy plants. Use soil mulching - this will help maintain optimal moisture.

Excessive watering can be another reason why tomato leaves curl. Curl from excess water starts from the lower leaves and gradually spreads to the tops of the plant. The leaf blades curl in a funnel-shaped fashion towards the upper surface along the central vein. The leaves become dense, hard to the touch and crumble easily. To prevent this from happening, tomatoes need to be watered correctly:

Tomatoes are one of the most capricious types of vegetables. And if you do at least something wrong in growing tomatoes, then they will immediately signal this. The most common whim is twisted leaves. Unfortunately, it is not always possible to establish why plants behave this way. But such behavior, in turn, can lead to the fact that the fruits of the plant become unusable. Therefore, today we will tell you why the leaves of tomatoes curl and what needs to be done to prevent this from happening.

Transplant the seedlings into another soil, slightly moist, light, breathable.

​First, make sure that the soil is not too dense, that the roots can breathe normally in it.​​until the soil dries out. When I started growing tomatoes, it seemed to me that I watered them sparingly.

Disinfect the soil in the greenhouse with a solution of copper sulfate: 60-80 g per 10 liters of water.

If the tomatoes are still sick, then buy fungicidal preparations in specialized stores. They will not only protect the plants, but will also nourish and feed them.

Another reason why tomato leaves curl is the wrong temperature regime. High temperatures - 35 ° C and above - will become a dangerous factor that can lead to twisting of the leaves of the tomato and the death of the plant. To avoid this, in hot weather it is necessary:
Water the tomatoes once a week, using 3-5 liters of water per bush. During the fruiting period - 2 times a week, using the same amount of water;
Due to the fact that many gardeners abuse the infusion of herbs, nitrogen and organic fertilizers, there is a lack of potassium, phosphorus and zinc in the soil. This may be the reason why the leaves of the tomato are curled. To ensure a balanced diet, it is necessary to fertilize the soil according to the following scheme:
Pour under the spine, literally 20 milliliters of water, you can make a slightly pink solution of potassium permanganate. Those. water so that the earth is moist in the place of the pot where the stem and root of the plant are located. Let the rest of the earth remain slightly moist.
In any case, you can try to save the plant in the following way.
So - the earth cannot be kept damp all the time. Water only when it is really dry. It is definitely time to water, even if the tomatoes are wilted even in the absence of sun. Except when they wither due to this very disease.

The reason why the leaves of tomatoes wither is Fusarium wilt. In the open field, the disease spreads to tomatoes in the southern regions, and in greenhouses everywhere. The first signs, in addition to wilting, is also the yellowing of the leaves. Then the whole shoots wither, and then all the plants.

How to properly feed tomatoes?

Strengthen ventilation and drafts, shade plants with lutrasil;

  • Use rainwater for irrigation - due to the presence of carbonic acid in it, it has a mild effect. Water should be warm - 24-26 ° C;
  • solute fertilizer at the rate of 2 tbsp. spoons per 10 liters of water;

Further, ideally, the plant is placed on a sunny window. If the roots are badly damaged, and the plant wilts in the sun, shade it, or move it to another window for a day or two. But then necessarily - a lot of sun, a lot of light. And little water. Most likely, following such simple recommendations, the seedlings will be saved. Although there is a lot of fuss.

To prevent this from happening, you need to carry out prevention. It must be carried out in dry and calm weather. If the summer is saturated with rains, then chemical treatment should be carried out as often as possible. But only when the tomatoes are still immature, ripe fruits cannot be processed. Carry out top dressing, which strengthens the immunity of plants, because the stronger it is, the more resistant the tomatoes will be to late blight. To combat late blight, you can use ash-based tincture and various products with the addition of copper.

Growing tomatoes in seedlings before transplanting to a permanent place is quite easy due to their unpretentiousness. However, even the seedling period can be accompanied by various problems: the leaves of the seedlings dry, the tomato turns yellow, and then leaf fall may begin altogether. To prevent such a phenomenon, it is necessary to determine the causes of the problem and try to prevent its occurrence.

seedling yellowing

Leaf color changes can occur at different intervals.

  • A gradual change in the color of the foliage of tomatoes indicates the presence of a cause that needs to be recognized in time and try to prevent negative consequences.
  • Sudden yellowing is evidence of the death of the root system. It is possible to normalize the condition of the plant only by timely feeding. However, most often such a sprout dies.


Causes of yellowing and their prevention

Why do tomato seedlings turn yellow? Nobody can give a definite answer. Yellowing of old leaves located near the ground is considered normal. There are many negative factors affecting the yellowing and subsequent drying of the leaves.

  • Change in air temperature.

Tomato is a heat-loving plant that does not tolerate sudden temperature fluctuations that retard the growth and development of sprouts. To prevent the leaves from drying out, it is necessary to regularly monitor the air temperature near tomato seedlings.

  • Lack of space.

Tomatoes need free space, therefore, with its lack, they turn yellow, and then the leaves dry out and fall off. To prevent this from happening, plants are transplanted as needed into more spacious dishes. When planting seedlings in one large box, you must observe the optimal distance between the bushes.

  • The formation of a lump of roots.

The wrong one contributes to its creation. The formed lump prevents the roots from transferring nutrients and water to the organs of the sprout, as a result of which the development of the entire plant slows down. To prevent yellowing of the foliage for this reason, it is necessary to do a proper bush transplant, trying not to damage the roots.

Tomatoes need to be transplanted into loose soil so that the tomato roots can breathe freely.

  • Lack of nutrients.

In this case, the lower leaves begin to turn yellow first. Most often this is due to a lack of nitrogen or potassium. This cause can be eliminated by timely application of the necessary fertilizers.

It is better to feed seedlings together with watering. To do this, the fertilizer is dissolved in water, and the resulting solution is poured into the hole in a certain amount.

  • Lots of nutrients in the soil.

Tomatoes also dry up and die from excessive feeding with urea or bird droppings. It is important to follow the rule: it is better to underfeed than to overfeed.

  • Excess moisture.

The tomato does not tolerate high humidity: with abundant watering, the foliage turns yellow and gradually dries out. Therefore, watering should be moderate after the soil has dried out. In hot weather, spraying can be done.

  • Lack of light.

So that the plant does not lack sunlight, experienced gardeners recommend placing dishes with seedlings in the brightest place, shading as needed. If daylight hours do not last long enough, then you need to organize additional highlighting in the mornings and evenings up to six hours a day.

  • Dry air.

When the tips of the leaves dry up, this indicates a small amount of humidity in the air. You can correct this mistake by placing a container of water next to the seedlings.

  • Salted soil.

In this case, the dry tips of the foliage appear along with white or yellowish spots. A large amount of salt in the soil draws water and nutrients from the plant. Those who are perplexed why the earth suddenly became salty and what needs to be done in this case should pay attention to the quality of the water used for irrigation: hard water contributes to soil salinization. It is necessary to change the top layer of the soil and free the plant from feeding for several weeks.

For it is better to use soft water: rain, melt or filtered.

  • Fusarium or late blight disease.

This is evidenced by the yellowness of the entire bush, which appeared as a result of a fungal infection. Most often, plants become infected with it at the seed stage or from infected parts of other tomatoes. Spores can enter the soil through the tools used to care for tomatoes. Infection is indicated by the gradual wilting of seedlings. You can suppress the development of the fungus with the help of special drugs.


yellowed seedlings

If the leaves have already turned yellow, then it is advisable to transplant the sprout into a new earth, warm and sufficiently moist. Before transplanting to a new place, it is worth examining the roots. If they are healthy, as evidenced by their white color without signs of rot, then the plant can be rehabilitated. If they are yellow or black, then such plants are likely to die.

Why the foliage may turn yellow as a result of a dive is easy to guess: either the root was injured, or the transplant was made too early. To save the tomato from wilting, it is recommended to do shading. After a couple of days, the sprouts will return to normal. You should not solve this problem by moving the seedling box to a room closed from sunlight, otherwise another problem will arise: the leaves will lose their brightness and stretch.


Disease Prevention

Fungal diseases are very difficult to fight. It is easier to take preventive measures.

  1. Collect seeds for future seedlings from adult bushes.
  2. Before planting, they must be etched in a 1% solution of potassium permanganate.
  3. Dishes for seedlings must be disinfected.
  4. Process all instruments.
  5. For seedlings, use soil in which there is no infection.

Before solving the problem of tomato wilting, it is necessary to determine why this happened, and only after that proceed to eliminate the cause. In order for the seedlings to develop normally and there were no difficulties with its cultivation, it is necessary to create optimal conditions for its development. Strong sprouts will delight you with quick adaptation when transplanted to a permanent place and a bountiful harvest, subject to all recommendations.

When growing tomato seedlings, you can encounter various problems. What measures should be taken if the leaves of tomato seedlings dry depends on the cause of the wilting. This process may be the result of improper care or disease. Before treatment, it is important to find out the cause, and only then proceed to eliminate it.

When growing tomato seedlings, you can face various problems.

Some gardeners cannot understand why the leaves of tomato seedlings dry. After all, a tomato is one of the unpretentious plants that grows in almost any conditions.

Some gardeners cannot understand why the leaves of tomato seedlings dry.

The main reason for the drying of seedlings is a violation of the agrotechnical conditions of cultivation.

  1. One of the banal reasons for the drying up of foliage is the lack of watering. Such a diagnosis can be made if small cracks appear on the surface of the soil. Even if visually the soil seems to be sufficiently moist, tomato seedlings need additional watering. However, there is another, completely opposite reason: often the leaves of seedlings begin to dry and fall off from excess moisture in the soil. Do not flood plants, it is better to limit yourself to moderate watering as the soil dries. With insufficient air humidity, the tips of the leaves dry up at the seedlings. To avoid this, you can place containers of water next to the tomatoes.
  2. Lighting. There are also two extremes here: lack of lighting and too bright rays. With a lack of sunlight, the lower and cotyledon leaves begin to dry. With an excess, there is a high probability of a sprout getting a sunburn, characterized by the appearance of whitish transparent spots that gradually dry out. To avoid drying out of the leaves for this reason, it is necessary to choose a well-lit place for the seedlings, shading them as needed on bright sunny days.
  3. If yellow or white spots appear on the soil and the tips of the leaves dry on the sprouts, then we can talk about an increased salt content in the soil. This most often occurs when using hard water for irrigation or applying a large amount of fertilizer. The roots in this case draw water and nutrients from the plant, contributing to its drying.
  4. Lack of heat. Drafts on the windowsill, cold soil, cool air contribute to the wilting of seedlings. Tomatoes need to be grown in a warm, but not hot room.
  5. Lack of nutrients. An indicator of zinc deficiency is the formation of gray-bronze spots on the foliage at first, which contribute to the drying of the foliage. If there is not enough potassium, then the sprouts first turn yellow, and then the lower leaves dry up.

Diseases and pests

If, with proper care, the foliage of tomato seedlings still dries, the cause may be fungal diseases or pests.

Among the diseases, the most common are the following:

  • - provokes the drying of the entire bush, which looks like it has not been watered for a very long time;
  • brown spotting - begins with the appearance of brown spots on the lower leaves, which gradually darken, spread over the entire area of ​​\u200b\u200bthe leaf and dry out;
  • septoria - characterized by the appearance of dirty white spots with a dark border;
  • with late blight disease, tomato leaves dry and curl.

Diseased plants are very difficult to cure, so it is best to simply prevent the development of the fungus. The fungus begins to develop at high humidity in conjunction with high temperatures, so one of the preventive measures to prevent the fungus is to maintain moderate humidity. The disease spreads through the soil, so special attention should be paid to preparing the soil in which tomato seedlings will be planted. If you do not take any measures to treat the tomato, then the whole plant will die.

The cause may be fungal diseases or pests.

To prevent late blight, you can spray with Hom or Oxyx preparations. In the absence of an ovary, the plant is treated in the same way at the first signs of the disease. For the treatment of tomatoes with formed ovaries, use better safe means, for example, Fitosporin.

seedling treatment

Having determined why the foliage dries up at the seedlings, it is necessary to immediately take measures to save the sprouts.

  1. If the reason for the drying of the seedlings is excessive watering, then it is transplanted into light, slightly moist soil. At the same time, it is important to free each root of the plant from the old earth and make sure that they are all healthy. If the color of the roots is yellowish or black, rot has appeared, then the plants cannot be saved. After transplanting, the sprouts are shed with a weak solution of potassium permanganate.
  2. Epin and timely shading will help restore the strength of seedlings burned by the sun.
  3. If the leaves of tomatoes dry due to lack of lighting, then in this case the seedlings are transferred to a more lit place. If possible, containers with seedlings are taken out into the street under the sun.
  4. To save a plant that is fading due to salting, you need to change the topsoil, use soft water for irrigation and refuse fertilizers for at least half a month.
  5. With a shortage of elements, the necessary fertilizers are applied to the soil. For example, an infusion of ash will help to make up for a potassium deficiency. To do this, pour a handful of ash into 1 liter of boiling water and insist. Water the seedlings with a solution of infusion, taken in an amount of 1 liter per 5 liters of water.

To save the seedlings from pests or at the first suspicion of the development of the fungus, you need to remove all the seedlings from the containers, rinse the roots well first with water and then with a solution of potassium permanganate, then dry them and plant them in another container in fresh soil.

If the leaves of tomato seedlings dry, then you must first determine the cause of the disease and only after that proceed with the treatment of seedlings. To get minimal losses, you should follow all the rules for growing tomatoes, one of which says: "More light, less humidity."
