The leaves of the tomatoes have curled up and are drying up. Why do the leaves of tomato seedlings dry and then fall off? Why do tomato leaves curl?

Tomatoes are one of the most common crops in dachas and household plots. In general, with proper care, tomatoes delight with high yields. However, in some cases, problems cannot be avoided, for example, drying out of the leaves.

Causes

There can be many reasons for the drying of leaves in tomato seedlings, but all of them can be classified into one of the following groups:

• improper care;
• disease damage;
• insect pest attack.

Practice shows that the main reason is still improper care. And even if the plant is affected by a fungus (that is, there is a disease), then the root cause of its development is usually still improper care.

Treatment

Treatment of tomatoes should begin with the diagnosis and search for the reasons for the drying of the leaves. Otherwise, you can aggravate the situation and achieve not only the death of the bush, but also the infection of the remaining seedlings.

Most diseases can be avoided by disinfecting the seeds and strengthening the immunity of the seedlings. As scientific studies show, up to 80% of diseases of adult plants can be avoided with proper preparation of seeds and soil for planting them.

Despite the fact that many modern varieties, primarily hybrid ones, are relatively non-capricious in nature, there is no “magic” method of treating tomatoes for all ailments. This once again confirms the idea that you first need to find the cause of the drying of the leaves, and then proceed to treatment.

Regardless of the cause of the disease, if it is impossible to cope with it, it is much more rational to remove the damaged bush. This will prevent infection of the remaining seedlings.

The hole of the affected bush should be disinfected, and for the remaining bushes, preventive treatment with a suitable agent should be carried out.

Diseases

Tomatoes are more susceptible to the development of fungal diseases. The most characteristic diseases of tomatoes, in which there is their complete or partial drying up are several ailments.

• Fusarium wilt, in which the entire bush dries quickly and dies. It looks like the plant has not been watered for a long time.
• Septoria, which is characterized by the appearance of gray-brown spots on the leaves with a dark drying edge.

• Late blight, the "clinical picture" of which is drying and folding of the leaves.
• Brown spotting begins with the appearance of brown spots on the lower leaves. The spots gradually increase in size, covering the entire leaf. The spots darken and dry out.
• Tobacco mosaic, in which the top of the bush first dries, and then turns brown and dries up, the leaves fall off.

Fungal diseases are not easy to treat, but they are easy to prevent. Usually the fungus appears at elevated temperatures and humidity. It follows that moderate watering and ventilation is one of the keys to preventing the development of the fungus.

It is important to follow the rules for planting seedlings. For 1 m2 when planting in a greenhouse or soil, no more than 4-6 bushes can be accommodated. Moreover, sprawling plants are planted at a greater distance from each other (at least 60-70 cm between the holes), and determinant varieties can be planted more closely.

In the pursuit of saving space when planting too closely, the humidity between the bushes increases, which leads to the appearance of fungus. In addition, the light in such "thickets" comes unevenly, which affects the fruiting and ripening time of the crop. Finally, caring for bushes planted in a heap is inconvenient.

If signs of phytophthora appear, the bushes are recommended to be treated with Oxyhom or Hom before the formation of ovaries. The same drugs are suitable for prophylactic treatment. If late blight affected the bushes during the flowering period, it is better to use the less effective, but safer Fitosporin remedy.

Pests

Among the most common pests are aphids and mites, which draw nutrients from the plant. The lack of the latter leads to the fact that the tips, and then the leaves completely dry out, the bush dies.

As a preventive measure, tomatoes can be sprayed with a 2% lime mixture, and when grown in a greenhouse, fumigated with a sulfur checker. For the treatment of affected bushes, it is better to use suitable insecticides.

Wrong growing conditions

One of the reasons for the appearance of dry leaves in tomatoes is excessively dry indoor air. This is a common problem when seedlings are grown on a windowsill or when using climate devices (heaters, air conditioners).

A hygrometer helps to determine how relevant this situation is. If the device shows that the air humidity is 40% or less, urgent measures must be taken to increase this value.

This can be done in several ways.

• Irrigation of air around seedlings. For these purposes, a spray bottle and water at room temperature are suitable. Direct spray should not be on the bush itself, but around it. It is recommended to repeat these manipulations several times throughout the day.

• If the main cause of dry air is working radiators, you can put water containers near them. In this way, you will contribute to the evaporation of moist air. It is recommended to choose a container of large volume with a wide neck.
• Installing a humidifier is one of the easiest and most reliable ways to adjust humidity levels. The advantage of this method is that it will definitely prove to be effective and will make it possible to independently choose the required moisture indicator. An important point - you should not install the device in close proximity to tomato seedlings.

Improper care can be associated with a lack of moisture, which also causes yellow leaves in the seedlings. First of all, you should make sure that there is a moisture deficit. To do this, you need to analyze the condition of the soil - if the top layer is dry, the soil is lumpy, crusted or cracked, it is likely that there really is not enough moisture.

Now you need to make sure that it is not enough in the lower layers. To do this, a dry wooden stick must be lowered to a depth of 10 cm, trying not to damage the roots of the tomatoes. If the stick is dry, then there is a shortage of water. If it is contaminated, then it makes sense to replace the topsoil.

To cope with the problem of yellow leaves on tomatoes, the appearance of which is caused by a lack of moisture, there are several methods.

• Establish a watering schedule - this crop requires abundant, but rather rare watering, while 1-2 times a week will be enough. On hot sunny days, you can make it more frequent, in cloudy and wet weather - rare.
• Young fragile bushes, on the contrary, are watered daily, in small portions. Their underdeveloped root system is not ready for a large volume of liquid, they will not absorb it, which will cause moisture stagnation. Frequent and gentle watering can be maintained until the formation of the first buds.
• When watering, you need to keep the container of water close to the roots, preventing the liquid from getting on the stems and leaves and flowing away from the roots.
• The root system of tomatoes practically does not absorb cold water. If you water the seedlings with such water, it first warms up in the ground, while the tomatoes suffer from a lack of moisture. If the situation repeats often, moisture stagnation in the soil cannot be avoided, which can cause plant diseases.

Another characteristic picture with improper watering is drying leaves combined with rotting roots. This happens just with an excess of moisture, which the plant for some reason is not able to absorb. One of the reasons has already been indicated - too cold water for irrigation. The optimum temperature of the liquid should be at least + 20 ... 22C.

However, in this case, adjusting the irrigation regime is not enough, you need to treat the plant. It is recommended to remove it from the ground and inspect the roots. If some of them are rotten, it must be cut off to healthy rhizomes. Otherwise, the plant will continue to wither and eventually die.

After these procedures are done, you need to learn how to properly water the plant.

Excessive application of mineral dressings is also fraught with yellowing and withering of the leaves. As a rule, a large amount of minerals is indicated by the appearance of white and yellow inclusions on the surface of the soil.

If you do not overdo it with fertilizers, remember what water you water your tomatoes with. If liquid from a water tap, then there is also a high probability of excessive soil mineralization. In tap water, the content of magnesium, chlorine, iron is exceeded. Tomatoes need to be watered with filtered or settled water.

You can save the seedlings by removing the top layer of earth by about 1 cm. Instead, you need to lay a new soil, after disinfecting it with a solution of potassium permanganate. In addition, it is important to establish an irrigation scheme, for 2-2.5 weeks to abandon the application of fertilizers.

If the leaves not only dry and crumble, but also brighten significantly, and the emerging new leaves are too small - most likely, the tomatoes lack minerals. As a rule, such a picture is typical with a lack of nitrogenous supplements.

In order to prepare the latter, it is necessary to pour one part of the litter with two parts of water and leave the resulting solution for 3 days. After this time, mix and filter the composition, dilute with clean water in a ratio of 1: 20. Pour top dressing, observing the proportions, because with a strong concentration of substances, the plant will get burned.

Nitrogenous fertilizers allow the roots to grow, as well as the green mass. They are not needed by seedlings during flowering and fruiting.

If the leaves not only turn yellow and dry, but also wrap inside, this may indicate a potassium deficiency. Correcting the situation will allow the introduction of special fertilizers or solutions based on ash. To do this, pour a tablespoon of ash with a glass of boiling water and insist for a day. The mixture is diluted with water in a ratio of 1: 5 and used for irrigation.

When growing tomatoes, it is also important to provide a suitable light regime. The lack of light causes the cotyledon and lower leaves to dry out, while the appearance of whitish spots on the leaves that gradually dry out indicates overly aggressive solar exposure. Such spots are nothing but sunburn.

This can be avoided by choosing a sunny place for seedlings, but not open to direct UV rays. On hot days, it is recommended to organize a blackout for the bushes. A burn can also be caused by watering or spraying seedlings in the heat. You shouldn't do this.

Castings dry, the plant withers with a lack of heat. We must not forget that tomatoes are southern plants, and even frost-resistant varieties die at a temperature of 0 ... + 5C. When the temperature drops to + 10C, the color is shed and biochemical processes are disturbed. The optimum temperature for growing a crop is considered to be + 22 ... 25C.

It is important that the temperature of the soil is also quite high. If you plant seedlings in cold soil, then it can begin to wither and dry, wither. But even if this does not happen, planting in cold soil is fraught with a decrease in yield, a belated fruiting period. The optimum soil temperature is considered to be within + 14 ... + 16C.

Prevention

Prevent infection of seedlings and, as a result, drying out of leaves, allow simple preventive measures.

• The soil before planting, as well as the growing containers, should be disinfected. The easiest way to do this is with a solution of potassium permanganate. The soil can also be calcined at a temperature of 200C in an oven for 15-20 minutes.

• You should not use the same soil for seedlings on which potatoes, peppers, eggplants grew in the past 1-3 years. In this case, there is a high probability of the preservation of spores of pathogens characteristic of nightshade in the soil.
• It is important to ensure proper care of tomatoes - abundant, but infrequent watering, loosening the soil after each watering.

If nightshade crops in your area are quite often infected with late blight, it is recommended to choose early-ripening varieties for planting. As a rule, by the time an “epidemic” of phytophthora occurs, a crop has time to form on such tomatoes.

Burnt seedlings can be restored by shading, as well as by treatment with Epin.

While the seedlings are small, it is recommended to water it with a drip method. At home, this technology is easy to implement using a medical pear. It is enough to draw water into it and lower the spout of the pear between the wall of the pot or box and the earthen clod, and then release the water. With this method, it will be possible to avoid waterlogging of the earth, most importantly, a tender seedling will not be washed away by a stream of water.

When growing seedlings in a greenhouse, it is important to remember that already in the morning in hot sunny weather, the temperature here reaches above + 30 ... 35C, which can lead to drying of the seedlings and burns of the leaves.

You can reduce the temperature by organizing ventilation and, if the time of day allows, abundant watering of the plants. In this way, you can reduce the temperature by 8-12C.

Experienced gardeners advise building greenhouses with a height of at least 1.5-2 m, as well as making them more spacious. In such structures, overheating of the air is less likely. Preferred materials are glass or polycarbonate. But polyethylene contributes to the formation of an unprofitable greenhouse effect (high temperature and humidity), and is also easily damaged.

• tomato virus
• - the plant was struck by a fungus
• Tomato seedlings are capricious, and require constant attention. If there is no constant bright light, water a lot or a little, then the leaves will dry. The seedlings also do not like drafts and cold, from this not only the leaves but also the seedlings themselves can die.

high temperature stress

If suddenly such a problem appeared with tomato seedlings and her leaves began to turn yellow, then it is necessary to adjust the frequency of watering. A lot of water when watering, or a small amount of it, are the main causes of yellowness; the roots may begin to rot or dry, well, keep it out of the shade.

bacterial infection

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.

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:

Also, do not fertilize tomatoes with manure or slurry: due to the release of ammonia, the leaves can get burned.

Why do tomato leaves wither?

Lack of moistureTomato, like any other plant, needs the right watering regimen. Its violation leads to the withering of the plant, and in the end to the rotting of the root system, which is the cause of the death of the tomato. To avoid this, water the seedlings daily, but little by little, preferably in the morning. After picking the plants, watering should take place once a week, while the water should be warm. Make sure the soil is completely wet. Before the next watering, the soil should be slightly dry. After planting the tomatoes in the greenhouse, water the plants once a week. Two hours after watering, reduce air humidity by opening the window and door in the greenhouse. Lack of light

• Seedlings can dry out due to infected soil, tomato seedlings dry out due to a fungal disease. The cause may be a lack of nutrients and insufficient watering, but more often a virus or fungus is the culprit.
• At its core, tomatoes are very fond of high soil moisture, as well as dry air. And if the soil is suddenly dry, this will immediately cause the leaves of the seedlings to begin to wither.
• Too dry air in the room
• If it's cold to the roots of tomatoes. For example, if the seedlings are standing on a cold window. In the same way, cold soil can affect seedlings.
• Phytophthora is the reason why the leaves of tomatoes dry. Phytophthora occurs due to frequent watering or incorrect temperature in the greenhouse. In addition to leaves, phytophthora also affects the fruit itself and in the shortest possible time is able to destroy the entire crop.

Why do tomato leaves dry?

Fusarium spreads especially quickly with high soil moisture and an excess of nitrogen fertilizers. The disease itself is transmitted by transplanting seedlings, watering and loosening the soil. Fusarium is also the reason why tomatoes wither.

Strengthen ventilation and drafts, shade plants with lutrasil;

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 I'm watering abundantly, but in 7-10 days 1 time! and I also add chicken manure diluted with water!​

The first point is the most common reason. Namely, the "aphid" struck the plants. And at the same time, you will never see the insects themselves. Recipe for seedling treatment: water with saltpeter, urea and spray plants with INTA-VIR. Watch this entertaining video on the topic of drying leaves from tomato seedlings: And a disease develops in tomatoes, which is called a fungus. And when there is the beginning of such a disease, the leaves lose their elasticity and even when they are watered, they will be withered.

And, of course, the leaves of tomato seedlings can dry from lack of light.

• 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.
• To avoid Fusarium wilt, you must:
• Treat tomato leaves with urea - 1.5 tbsp. spoons per 10 liters of water, and after 1-2 days with raspberry-colored potassium permanganate.
• 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;
• - a very light-loving culture. Light day should not be less than 12-14 hours a day, and the light intensity should be high enough. To do this, use daytime lighting. At a height of one meter above the young plants, install a lamp with an energy-saving lamp with a power of 18 watts. Place boxes with seedlings on the windows of the southwestern exposure. Sunlight reflectors (foil, white paper) can be placed at soil level. Lack of mineral fertilizersTomatoes, like any other plant, love top dressing, and it should be fertilized both during planting and during flowering. During the growing season, make three to four root dressings. The first should take place 20 days after planting. For 10 liters of water, put 1 tablespoon of nitrophoska and a 1.5-liter jar of mushy mullein. Based on 0.5 liters per plant. The second - at the beginning of the blooming of the second flower brush. For 10 liters of water, put a 1.5-liter jar of diluted chicken manure, 2 teaspoons of superphosphate, 1 teaspoon of potassium sulfate. The third - during the blooming of the third flower brush. For 10 liters of water, add 1 tablespoon of complex mineral fertilizer. The fourth - 10 days after the third. For 10 liters of water, put 1 tablespoon of nitrophoska. During the flowering of the second and third flower brushes, spray the plants with a solution of boric acid (1 teaspoon per 10 liters of water). Plant disease The disease most often occurs in protected ground. Withering begins with the leaves, then the whole bush withers. Precautions depend on the type of injury. For example, with bacterial cancer, it is impossible to treat affected tomatoes. Destroy diseased plants as soon as possible. Planting tomatoes in the same place leads to the accumulation of diseases, which is the cause of wilting. Therefore, return the plants to their original place in at least 3-4 years.

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.

Tomatoes are watered less often. I heard such a thing as "dry watering", i.e. loosening. and the fact that you have watering 2-3 times a week is not watering, but a mockery. you need to water once a week, so that the earth absorbs moisture to a depth of 25 cm, and does not nail dust. and not along the leaf, but under the root. there will be no diseases.

The leaves of tomato seedlings can dry out and fall off more often due to lack of lighting. These are the lower and cotyledon leaves. They become pale, turn yellow, and then fall off. I would not say that they dried up, they just fell off - that's all. The problem is solved simply: you need to spread the cups with seedlings as wide as possible and take them out into the wild as soon as possible: a balcony or a greenhouse.

Some gardeners are faced with such an unpleasant phenomenon as drying leaves on tomatoes. Often this phenomenon is associated with a lack of moisture in the soil, but more often the leaves of seedlings dry out from its overabundance. In such cases, it is recommended to take watering under strict control and water the tomatoes in small portions of water, but more often. It is also necessary to pay attention to the leaves themselves - are there any traces of pests on them, and also to exclude the possibility of sunburn.

Nadezhda Kotsareva

And the leaves can dry out from overflow. Since the swamp does not allow the roots to eat as needed, and the plant is starving. Accordingly, sheds foliage.

What should a gardener pay attention to if a tomato leaves curl in a greenhouse? First, for watering. The first reason why tomato leaves wither in a greenhouse is excessive or insufficient watering.

• Young, newly transplanted seedlings need to be watered a little every morning.
• Adult plants are watered much less often - once a week during the period of growth and flowering, and twice when the plant bears fruit. Watering should be plentiful, as the roots of plants go deep into the ground. Under each bush it is worth pouring 3-5 liters of water.

All leaves should remain dry when watering. The ingress of moisture on the green part of the plant leads to the appearance of mold and fungus, the development of diseases and the death of the entire crop.

The second reason why the leaves wither is the high temperature in the greenhouse. Despite the fact that tomatoes love heat, an increase in the temperature in the greenhouse of more than 35 degrees Celsius is detrimental to them, and leads to the fact that the leaves of tomatoes curl and turn yellow. Still high temperature contributes to the development of harmful microflora and the appearance of pests. To avoid unpleasant consequences, the greenhouse must be ventilated in a timely manner, and in the very heat it is generally better to remove the film. But in this case, it is better to cover the tomato plants with foil or a light-colored cloth that will reflect the light.

But even the high temperature in the greenhouse is not as detrimental to plants as the lack of light. This problem is especially relevant in polycarbonate greenhouses: condensation accumulates on their walls, which poorly transmits sunlight. To avoid this cause of leaf wrapping, you need to ventilate the greenhouse more often. In addition, in the northern latitudes, summer ends early and the daylight hours are short, so many gardeners install panels that capture and reflect light, and hang lamps in the greenhouse that supply the plants with the ultraviolet they need.

Is overnutrition or undernutrition more dangerous?

• For example, an excess of nitrogen in the soil leads to intensive growth of greenery and abscission of flowers. To cope with excess nitrogen in the soil, plants should be watered and sprayed with ash or potassium fertilizers. The lack of nitrogen in the soil is also dangerous: from this, in the greenhouse, the tomato leaves curl and wither, and the plant dies.
• Potassium deficiency is common, especially in seedlings in pots and shrubs that have just been transplanted into the greenhouse. At the same time, the tomato leaf looks yellow and withered from the edge, at the very tip, and if the soil is not fertilized in time, the entire leaf will turn yellow.
• Magnesium deficiency can cause leaf wilt. In this case, the bushes may first turn yellow, and then acquire a reddish tint.

And a deficiency, like an excess of any mineral substance, can be detrimental to a plant.

Often the reason why the leaves of a tomato dry is damage to the plant. This can be improper pinching and pinching, when an inexperienced gardener cuts too many leaves at a time or leaves an uneven cut that gets infected. As a rule, tomatoes deprived of leaves are more easily infected with unpleasant diseases like late blight. Damage to the root system leads to the fact that the plant cannot absorb water and nutrients from the soil, and begins to bear fruit later than others.

Often gardeners, looking at half-dead beds, wonder why the leaves wither. And the answer is simple - tomatoes are sick.

• For example, plants are often affected by the tobacco mosaic virus, which first infects the leaves and then the fruits.
• An equally serious disease is late blight, from which the leaves of tomatoes in the greenhouse begin to turn yellow and wither.
• Fusarium wilt tends to cover greens in a light bloom, and can cause curling.
• Curly virus. One of the most unpleasant diseases, which, moreover, is not treated. All that can be done is to remove and burn diseased bushes, and disinfect tools. The virus is carried by insects and persists on tools.



To get rid of diseases, it is necessary to observe the temperature regime, properly water and pinch the plants, and feed the tomatoes in a timely manner. And in case of illness, use proven medicines. Sick plants are immediately removed from the greenhouse and destroyed to prevent infection of healthy bushes.

The first cause of all diseases is the weakened immunity of the tomato plant. Healthy tomatoes usually fight off viruses and bacteria successfully, and gardeners have no question why tomato leaves curl in a greenhouse or outdoors.

Equally unpleasant causes of twisting are damage to the greenhouse by insects. To determine which pests attacked the seedlings, you need to carefully examine the leaves, especially from the back.

• Aphids are small black insects that hide in folds. They not only suck the juice from the bush, but also inject a substance that causes deformation of the plant. When dealing with aphids, it is best to spray the entire greenhouse with insecticide.
• Whiteflies are small white insects that live in huge colonies. An adult develops from an egg in 15-20 days, and their larvae not only eat the greens of almost any crop, but also very quickly become invulnerable to insecticides. In addition, their waste products are perfect for the reproduction of the fungus. For the winter, these insects burrow into the ground, therefore, for prevention, it is recommended either to change the soil, or to dig it deep and loosen it before the onset of cold weather.
• Spider mites are very fond of dry grass. Often inaccurate mulching leads to the fact that tomato bushes are also affected by this pest. These insects live on the lower leaves, and I hit a healthy plant in just 1-2 weeks. The pest is very tenacious and folk remedies do not help in the fight against it, so you need to purchase a special insecticide in the store, which sprays the entire greenhouse.

There are many answers to the question why the leaves wither. Before doing anything, you need to analyze the causes of leaf deformation, check how often watering, fertilizing is done, whether there is enough light for the tomatoes and whether it is too hot in the greenhouse. Often at this stage it is possible to make the necessary changes and save the crop.

Often gardeners observe such a phenomenon as twisting the leaves of tomatoes.

What could be the reason, we will find out in today's article.

Too little or too much moisture

One of the reasons why tomato leaves curl inward is lack or excess of moisture. When thirsty, the plant, in order not to die, evaporates a smaller amount of moisture, while the leaves are twisted inward with a boat. To help the plant, it is enough to water the plant often, but little by little.

paradox, but overflow- the second reason why the leaves of tomatoes are twisted. Plants can suffer even due to heavy natural rainfall, in this case the leaves curl up. If the plant suffers from stagnant moisture in the soil, it is necessary to work on loosening the soil so that moisture seeps out faster.

high air temperature

To the question that often worries gardeners, why do tomatoes curl leaves in a greenhouse, the answer is quite simple. The most basic reason is unsatisfactory temperature conditions. The lower layers of the soil are usually always much colder than the heated surfaces, so it is necessary to balance the temperature by ventilating the greenhouses.

If the leaves on the tomatoes began to curl in open ground conditions, the heat bothers them. This usually occurs when the temperature rises above 35 °C. Such heat provokes an accelerated decay of useful elements, the plant cannot fully assimilate them, starvation sets in and, as a result, the leaves dry, curl, and may even fly around the color. To save tomatoes from such stress, spray them with urea: one and a half tablespoons per 10 liters of water. After three to four days, treat with potassium permanganate.

Pinching errors

A fairly common reason why tomato leaves curl inward is incorrectly carried out pasynkovanie. The procedure should be carried out once or twice a week, if done less frequently, waiting for thickets, the plant will get stressed due to the large number of removed shoots.

Important! It is desirable to carry out pinching on sunny days: so the wounds heal faster. If the weather is cloudy all the time and you have to stepchild without the sun, treat the sections with wood ash after the procedure.

Proper pinching involves removing stepsons first from healthy bushes, leaving weak and suspicious-looking ones for later, thus avoiding tomato diseases and twisting leaves due to them.
