When tomato leaves turn yellow and dry out, this means that the rules for growing the plant have been violated. Explanations for this can be different - these are pests, any diseases, microclimate disturbances or a lack of nutrients. Now in more detail about each reason and what to do to prevent the leaves on tomatoes from turning yellow.

Microclimate disturbances

For normal growth it is necessary that there be certain conditions. Often, yellowing of leaves occurs due to the fact that the temperature or watering conditions are not suitable for the tomatoes. Accordingly, it is necessary to correctly identify the causes in order to get rid of the problem.

Temperature

For tomatoes to grow fully, they need a certain temperature: 20-25 degrees during the day and 18-20 at night. Tomatoes perceive temperature changes, especially sudden ones, extremely negatively.

Wilting and yellowing of the leaves of the plant is the first sign that the temperature is above normal. If this continues in the future, the inflorescences will begin to fall.

Important! To reduce the temperature in a tomato greenhouse, it needs to be ventilated. Therefore, it is necessary to have windows in the greenhouse; this should be taken into account when designing the structure.

To reduce exposure to ultraviolet radiation on tomato seedlings, you need to cover the glass in greenhouses with lime or use containers with cold water placed between the bushes.

In open ground, a canopy will help save the shoots from excessive temperatures. An excellent and simple option would be a piece of white fabric.

Watering tomatoes

One of the reasons that Tomato leaves turn yellow and dry out - improper watering. The vegetable crop prefers abundant watering, but not frequent. The tomato root system is well developed; they can receive moisture and beneficial elements from a depth of up to one meter.

Important! The optimal regime for watering tomatoes is twice a week at the rate of 3 liters of water for each bush.

If there is enough rainfall, you can water less often. It is necessary to water at the root, avoiding water getting on the leaves and stems, so as not to cause a burn.

Water tomatoes with warm water. An excellent option would be rainwater collected in a container and heated in the sun. The best time for watering is morning or evening, when there is no direct sunlight. When the tomatoes begin to bloom, you can slightly increase the frequency of watering.

Mulching with compost or straw will be a good help to ensure that the humidity level is maintained at the desired level. Another useful property of mulch is the amount of weed growth, without the need to loosen the soil.

Yellowed tomato leaves may be a signal to adjust the watering scheme.

Fertilizer shortage

It happens that tomato leaves begin to turn yellow, if there is an insufficient amount of nutrients in the soil. This often happens in greenhouses over a large area or in open areas, in other words, where it is more difficult to control the quality of the soil.

Nitrogen

When a plant lacks this substance, it is immediately noticeable. The main signs are yellowing and falling off of dried tops. If this problem is not corrected urgently, the bushes begin to stretch out and the shoots become pale.

Important! It is necessary to apply fertilizers with nitrogen when transplanting tomatoes to a permanent place and when the fruits begin to set.

The benefit of nitrogenous fertilizers is the growth of green mass. Urea can be used for feeding. To do this, you need to dissolve 40 g of the substance in a bucket of water and spray the plantings.

The main thing is not to forget to dose fertilizers correctly. If there is too much nitrogen, the tomato tops will grow vigorously. The crop needs to be fed only until its condition improves.

Potassium

With a lack of this substance, the leaves turn yellow and dry, and the young shoots curl into a boat. Small spots appear along the edges, which subsequently merge with each other, causing the leaves to dry out.

Plants are fertilized with potassium during the growing season, at any stage. But you should pay attention when the fruits begin to ripen.

Advice! Fertilizers containing potassium must be chosen without chlorine.

You can choose potassium sulfate for such feeding. Thanks to it, the amount of vitamins and sugars in vegetables will increase, which allows the plant to acquire resistance to diseases.

To feed the tomatoes, take 40g of potassium sulfate, which must be dissolved in a bucket of water. Water the crop at the root or spray it on the leaf.

Magnesium

If its quantity is insufficient, the leaves first turn yellow along the veins and then curl.

Magnesium sulfate will help restore the normal level of this substance. For watering at the root, take 40 g per 10 liters of water, and for spraying - 20 g per the same amount of water.

The beneficial properties of magnesium include helping in the absorption of other substances such as nitrogen, phosphorus and calcium. This has a positive effect on the yield, the taste of the fruit, and the speed of development.

Sulfur

By the appearance of red veins on the leaves, which acquire a light green tint and subsequently turn yellow, a sulfur deficiency can be diagnosed. If this deficiency is not corrected, the stems become weak and brittle.

Ammoniated sulfate is well suited to restore sulfur deficiency. It can simply be dissolved in water for watering tomatoes. This will provide vegetables with sufficient amounts of sulfur and potassium.

Iron

Chlorosis occurs due to iron deficiency. In such cases, yellow leaves appear, but the veins remain green. With a long-term deficiency, the color at the top of the bush loses brightness and saturation, and the bush stops developing.

To compensate for iron deficiency, use a solution of iron sulfate. To prepare, take 5g per bucket of water and spray tomato bushes. To consolidate the result, you should repeat the procedure after 7 days.

Diseases that affect culture

Diseases are also one of the causes of yellowing leaves. They occur in several cases: with excess moisture or improper care of plants. It is necessary to fight diseases with special drugs.

Fusarium

This disease is caused by fungal spores. The disease affects roots, stems, tops and fruits. Although the plant is affected at any period of its growth, it is especially common during the formation of fruits.

Symptoms of the disease include yellow leaves that curl and wilt. When cut through the stem, brown vessels will be visible. The disease affects the bottom of the plant, smoothly moving to the top.

If fusarium has already appeared on a plant, it must be destroyed so that the infection does not spread further. Preventive methods include treating seeds with fungicides before planting, as well as tilling the soil. Plants must be planted at a distance of 30 cm from one another, weeds must be controlled in a timely manner and the soil must be loosened.

Late blight

A fungal disease that manifests itself by the formation of brown spots on yellowing leaves.

If this disease is detected, the infected parts should be destroyed and the greenhouse should be ventilated to reduce humidity.

After this, healthy plants must be treated with biological preparations, for example, using Fitosporin or Trichophyte. After spraying, it is necessary to rinse the tomatoes that will be eaten especially thoroughly.

Chemicals “Quadris”, “Hom” and “Ridomil” can be used only if the crop begins to ripen in a month. They are also used after harvest to disinfect the greenhouse and soil.

For prevention purposes, you can use a solution of 15 drops of iodine, a liter of milk and 9 liters of water. Spraying with this product helps to form a film on the surface, thanks to which harmful bacteria cannot penetrate inside.

The appearance of pests

Tomatoes suffer from aphids, spider mites and whiteflies. These pests suck sap and vitality from plants. Their spread leads to yellowing of foliage and wilting.

Insects can be controlled by spraying. The preparations “Inta-vir” and “Iskra” are used if there is a month before the tomatoes begin to ripen. They will not harm the crop and soil, but will have a paralytic effect on the nervous system of pests.

"Biotlin" is used if the crop ripens in less than a month. This drug works faster.

Other reasons

At the stage of growing seedlings tomatoes in greenhouses may turn yellow due to insufficient lighting. This problem can be solved by installing a white fluorescent lamp. The culture should be in the light for 8-10 hours.

Yellowing below may indicate mechanical damage to the roots. This happens when loosening the soil or when planting plants in open ground. The plant will regain its color when fully established.

Conclusion

The yellowness of tomato leaves often depends on the environment and the presence of nutrients in the soil. Inconsistency in temperature conditions or watering schemes can have a detrimental effect on the condition of the plant and the crop as a whole.

If the cause is disease or the planting is suffering from pests, the tomatoes are sprayed with special solutions. Sometimes folk remedies that are safe for plants and fruits are used for this.

Hello, dear readers! Tomatoes are a demanding crop, but not capricious. With proper care, tomatoes do not claim any special treatment, but often even the most pedantic summer resident is let down by the weather forecast or the ordinary busyness of a modern person. One week and the moment is gone.

Accidental overfeeding, drought, infection, and now we have some symptoms of malaise, and it is important to take the right measures. If you understand what signs plants give you, you can eliminate the problem in time and save the harvest.

Symptoms of tomato malaise

One of the common symptoms of illness in tomatoes is drying leaves, and the most obvious reason for this is the well-known late blight. Incorrect, untimely, and too frequent watering of tomatoes can lead to...

Precipitation awaits tomatoes grown in open ground, condensation is dangerous for greenhouse tomatoes, and cold dew on the foliage of this crop that is not covered in time is a fertile ground for the growth of fungus.

Drying leaves are not so bad. Late blight affects the entire plant from the trunk to the fruit, and the fruits often die, not least of all. That is why it is important to notice and prevent the occurrence of this sore in time. This infection is fungal, the fungus spreads with lightning speed, so you need to act very quickly.

Moreover, plants need to be treated with powerful and proven means, but there is one universal one, and it is the most effective. This is prevention! Let's prevent the disease, and it won't come close to our greenhouses!

What to do against late blight?

Preventive measures in the form of spraying plants against late blight should be carried out in cloudy and dry weather and on still unripe fruits. And in rainy summers, process tomatoes as often as possible. Plant nutrition should be comprehensive, strengthening the immune system, so that the plants can independently cope with any infection.

Experienced summer residents approve of preventive treatment of foliage with the addition of any product containing copper. It is this method that is used when the first dry leaves of tomatoes are detected.

But what if there is no late blight on tomatoes, and you are sure of this in the absence of other signs of the disease and the presence of preventive treatment? If the weather outside is beautiful without hot days and the nights are warm, then the reason lies elsewhere. To quickly identify the culprit, I propose to consider other cases of the problem and understand why the leaves of tomatoes dry out.

For what reason can leaves still dry out?

Problems of a very different nature can arise for summer residents from the very beginning of the season and continue until its end. Sometimes, even in infancy, tomatoes can become sick, and the seedlings will dry out the tips of the leaves and stunt growth.

The first thought that any gardener should have is insufficient nutrition in the soil or its excessive acidity, since tomatoes need low soil acidity. In this case, we feed the plants with a complex microfertilizer containing alkalizing substances.

Another factor influencing the dryness of foliage in seedlings is a weak root system. The pots may be too small for the tomatoes and there is no room for the roots to develop, so they begin to get rid of what they think are extra leaves so as not to waste energy.

Sudden temperature changes have a negative impact on plants at any age and, even with normal moisture balance, they can become stressed and lose their leaves. Before this, the lower leaves first wither, curl, then turn yellow and finally dry.

The lack of sunlight has no less effect on the condition of the greenery; try adding more lighting if you notice that the tips of the leaves have turned black.

Fungi that are dangerous for tomatoes are not only called late blight; there is also another infection that causes leaf death - fusarium.

Fusarium wilt occurs when a tomato ridge is infected with a fungus that penetrates the soil. The roots become infected, and the fungus infects the plant higher up the stem, cutting off access to nutrition and causing rapid death.

Fusarium fungus spores are carried by the wind, so it is important to treat tomatoes in gardens collectively so as not to throw bacteria to each other one by one through a fence, like a tennis ball through a net.

How to prevent fusarium?

The main methods of combating the disease are reducing factors favorable to it, such as moisture and heat, as well as preventive measures even when sowing seeds for seedlings.

The soil for seeds must be properly prepared and supplied with the necessary microelements for proper nutrition. Use certified seeds and disease-resistant tomato varieties.

It is advisable to disinfect the boxes for seedlings, but it is better to use new ones every year. If the seedlings have begun to grow, but have not gained strength, it is necessary to carry out unscheduled foliar feeding by spraying the shoots with 1% universal fertilizer for seedlings.

You can’t remember all the nuances, you can’t prevent all diseases, so it’s more important to always be on the alert!
But how can you accurately determine which fertilizer is best if there is so much choice, how can you understand what watering temperature is optimal if the climate is so unpredictable. Nowadays, there is an abundance of information for this, it is unrealistic to test all of it in practice and systematize your work, and it is incredibly difficult to understand and comprehend.

Surely some of the most meticulous summer residents have developed this amazing simulator "A bountiful harvest", which allows you to bring to life the most daring ideas and conduct an experiment that hardly any gardener would dare to do without fear of spoiling the harvest.

The virtual dacha will help you edit errors online and go out to your “plantations” confident in your actions.

A grateful blogger in my person will always find a minute for his readers and answer any questions and will not ignore your comments. Follow new releases, invite your friends with you.

Happy harvest and see you soon!

Why do tomato leaves curl?

​Tomato leaves can also curl due to strong pinching or pinching, as well as frequent watering. As a rule, plants experience such a situation when the second half of the growing season begins. The lower leaves are the first to react to this, after which the higher leaves begin to curl up to the very top. When curled, the leaves have the shape of a funnel, where the axis is the central vein, and the leaf itself, when curled, is directed towards the upper surface. These changes compact their plates, make them hard to the touch and brittle. If the flowers of such plants are excessively twisted, then, as a rule, this is followed by their falling off.

6. Along with this, curling of tomato leaves can be caused by the application of large quantities of organic fertilizers, herbal infusions, as well as nitrogen-containing fertilizers against the background of a sharp deficiency of phosphorus, potassium, copper and calcium. The situation can be corrected only by including the necessary microelements in the diet. To do this, fertilize with complex fertilizers, for example, mortar (a couple of tablespoons per bucket of water) or potassium monophosphate (a teaspoon per bucket of water).​ ​destroy plant residues;​

Tomato leaves curl down

​The second reason is incorrect, excessive feeding. Excessive nitrogen content in the soil leads to the fact that the stem of the bush becomes thick and powerful, but at the same time the leaves of the tomatoes curl. This problem is fairly easy to fix. To do this, you need to water the soil generously several times: the water will wash away the excess fertilizer. The main thing is not to overdo it, since stagnation of water is extremely undesirable: it can cause rotting and fungal infection. If you are afraid to overdo it with “water procedures”, simply balance the excess nitrogen with potassium. You can feed the plant with potassium sulfate, or you can fertilize the soil with ash, which also contains this substance.

Why do the leaves of tomato seedlings curl downwards?

​Lack of essential nutrients in the soil.​

​Gardeners are very sensitive to growing seedlings, so even a slight deviation from the norm in their condition causes them concern. Their fears are not always confirmed. For example: if the leaves of a tomato seedling curl downwards and at the same time resemble the shape of a chicken foot, then this is not a sign of a disease. This change occurs because the vein grows faster than the leaf plate itself, and therefore curls. Also, the curling of the leaf ends may be a species feature of the variety, which is more visible in young plants than in adults.​

​. If your greenhouse is too hot and the thermometer readings exceed 35 degrees, then the leaves may not have enough moisture, which they need for natural cooling. At this temperature, nutrients are less absorbed and the leaves begin to starve. As a result, you can observe curled leaves on tomatoes. And in especially severe cases, they can even dry out. To save tomatoes, it is enough to water the plant well once, and also additionally spray its leaves with urea (you need two tablespoons of liquid per bucket of water). After two days, instead of urea, use a weak solution of potassium permanganate.

Why do tomato leaves wither?

To prevent this from happening, prevention must be carried out. It must be carried out in dry and calm weather. If the summer is full of rain, then chemical treatment should be carried out as often as possible. But only when the tomatoes are still unripe, ripe fruits cannot be processed. Apply fertilizing that strengthens the plant’s immunity, 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.​

​By taking the necessary preventive measures, you will stop wondering why tomatoes are drying up. And your harvest will be tasty and healthy!​

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

​use mulching of the soil - this will help maintain optimal moisture.​

Due to the fact that many gardeners abuse infusions of herbs, nitrogen and organic fertilizers, there is a lack of potassium, phosphorus and zinc in the soil. This may be the reason why tomato leaves curl. To ensure balanced nutrition, it is necessary to fertilize the soil according to the following scheme:

​Cultivation begins with a process such as planting tomato seeds. The seedlings are then transplanted into a greenhouse or open ground (depending on climatic conditions). After some time, the bushes grow, flowers appear on them, and then small green tomatoes. It would seem that it will be possible to harvest the crop any moment now, but the problem is that the leaves of the tomatoes are curling. What to do in this case?​

​Excess of boron and zinc in the soil. Too many of these elements are accompanied by the following symptoms:​

​It is necessary to maintain a certain level of soil moisture, avoiding drying out or excessive moisture. Adding complex fertilizers to the soil, which include microelements such as potassium, calcium, phosphorus and copper, will promote the active growth of tomatoes and keep its leaves fresh and green. It is also necessary to carefully inspect the plant for the presence of pests such as spider mites, tobacco thrips, whiteflies and Colorado potato beetles. If you find that the tops of the leaves of your tomatoes have curled, then do not be upset: adequate treatment will help restore them to their original appearance. If you initially strictly follow the agricultural technology of growing tomatoes, then you will never recognize such a problem as leaf curling.

Gardeners often observe the phenomenon of leaves curling in tomatoes.

We'll find out what the reason might be in today's article.

Lack or excess of moisture

One of the reasons why tomato leaves curl inward is lack or excess of moisture. When experiencing thirst, the plant evaporates less moisture in order not to die, and the leaves curl inward. To help the plant, it is enough to water the plant often, but little by little.

It's a paradox, but overflow– the second reason why tomato leaves curl. Plants can be damaged even due to heavy natural precipitation; in this case, the leaves curl up with their edges. If the plant suffers due to stagnant moisture in the soil, work must be done to loosen the soil so that the moisture seeps out faster.

High air temperature

To the question that often worries gardeners, why tomatoes' leaves curl 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 begin 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 decomposition of useful elements, the plant cannot fully absorb them, starvation sets in and, as a result, the leaves dry out, curl up, and the color may even fly off. To protect 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.

Stepping errors

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

Important! It is advisable to carry out pinching on sunny days: this way the wounds heal faster. If the weather is always cloudy and you have to cut without the sun, after the procedure, treat the cuts with wood ash.

Correct stepsoning involves removing the stepsons first from healthy bushes, leaving weak and suspicious-looking ones for later, in this way you can avoid diseases of tomatoes and curling of leaves because of them.
It will help the plant cope with the stress suffered as a result of pinching. foliar fertilizer with a biostimulant.

Did you know? A study of the composition of tomatoes showed the presence of the substance lycopene in them. The human body is not able to produce this substance, which is bad, since this element, being an antioxidant, supports the functioning of the cardiovascular system and is a means of preventing cancer. According to scientists, regular consumption of fresh tomatoes or sauces made from them significantly reduces the risk of cancer.

Incorrect feeding

Watering is normal, we plant according to the rules, the temperature is acceptable - why do the leaves of tomatoes still curl? It could all be a matter of feeding, an excess or deficiency of any element will provoke painful reactions in tomatoes.

An excess of zinc is manifested in a purple color of the lower part of the leaf blade and curling of the edges. Too much manganese will cause leaves to become too brightly colored and have a wrinkled surface.

Curling of the leaves of tomato seedlings downwards indicates a lack of sulfur, copper or boron. If the leaves are bent with their edges up, they lack calcium; if there is a lack of phosphorus, in addition to curling, the leaves take on a gray tint. To avoid unpleasant consequences, add balanced complex formulations, for example, monopotassium phosphate or “Solution”.

Damage to the root system

Why do the leaves of tomato seedlings curl and what to do about it? The reason may be that The seedlings were overgrown, and during transplantation the overgrown roots were damaged. There is no need to do anything about this; you should give the seedlings the opportunity to recover and stop feeding. Now it is important for the plant to strengthen and heal the root system, and not to develop leaf mass, so as soon as the roots are restored, the leaves will take on a normal appearance.

Interesting! Tomato juice is an excellent marinade for barbecue. Tomato fruits contain acids that are safe for the human body and tend to soften food tissue.

Tomato pests

Immediately when pests are detected, treat the tomatoes by spraying. Such drugs as “Alatar”, “Biotlin”, “Fufanon” are suitable for this. Traditional methods are also effective against insects: infusion of marigolds, infusion of onion pulp with peels, and others.
