Often gardeners observe such a phenomenon as the twisting of leaves in tomatoes.
What could be the reason, find out in today's article.
Lack or excess of moisture
One of the reasons why the leaves curl up inside the tomatoes - lack or excess of moisture. Thirsty, the plant evaporates a smaller amount of moisture in order not to die, while the leaves are twisted inwards in 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 leaves curl in tomatoes. Plants can suffer even due to heavy natural precipitation, the leaves in this case are curled upwards. If the plant suffers because of the stagnation of moisture in the soil, it is necessary to carry out work on loosening the soil so that the moisture seeps faster.
High air temperature
To the often troubling gardeners the question of why tomatoes have leaves in a greenhouse curl, 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 airing the greenhouses.
If the leaves on the tomatoes began to curl in open ground, they are hampered by heat. This usually occurs when the temperature rises above 35 ° C. Such a heat provokes an accelerated decomposition of useful elements, the plant cannot fully absorb them, fasting occurs and, as a result, the leaves dry, coagulate, can even fly around 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.
Shoot errors
A fairly common reason why tomato leaves curl inward is wrong pasynkovanie. The procedure should be carried out once or twice a week, if carried out less frequently, waiting for thickets, the plant will receive stress due to the large number of remote shoots.
Important! It is desirable to carry out the grazing on sunny days: so the wounds heal faster. If the weather is cloudy all the time and you have to go without sun, after the procedure, cut the cuts with wood ash.
Proper staving involves removing the stepsons first in healthy bushes, leaving weak and suspicious looking for later, thus avoiding diseases of the tomatoes and twisting the leaves from them.
To cope with the stress transferred to the plant as a result of cracking will help foliar fertilizer biostimulant.
Did you know? A study of the composition of tomatoes showed the presence of lycopene in them. The human body is not able to produce this substance, which is bad, because this element, being an antioxidant, supports the cardiovascular system and is a means of cancer prevention. According to scientists, regular consumption of fresh tomatoes or sauces from them significantly reduces the risk of cancers.
Incorrect dressing
Watering is normal, stepson according to the rules, the temperature is kept acceptable - why do tomatoes still curl leaves? The whole thing can be in the dressings, an excess or deficiency of any element provokes painful reactions in tomatoes.
Excess rate of zinc is manifested in the purple color of the lower part of the leaf plate and twisting the edges. Too much manganese will cause too bright leaf color and a wrinkled surface.
Curling the leaves of tomato seedlings down indicates a lack of sulfur, copper or boron. If the leaves are bent upwards - they lack calcium, if there is a shortage of phosphorus, besides twisting, the leaves take on a gray tint. To avoid unpleasant consequences, make balanced complex compounds, for example, potassium monophosphate or "Dissolved".
Attention! It is not recommended that a large amount of slurry or rotted manure, they contain a lot of ammonia, which provokes burns of hardwood and fruit damage.
Root system damage
Why leaves curled around tomato seedlings and what to do about it? The reason may be that the seedlings have outgrown, and when transplanted, too-grown roots are damaged. You do not need to do anything about it, you should give the opportunity for the seedlings to recover, stop feeding. Now it is important for the plant to strengthen and heal the root system, and not to develop a deciduous mass, therefore, as soon as the roots are restored, the leaves will take on a normal appearance.
Interesting! Tomato juice is a great marinade for kebabs. The fruits of tomatoes contain acids that are safe for the human body and have a tendency to soften the tissue of the products.
Tomato pests
You should check the plant for the presence of insect parasites. Aphids, whiteflies and red spider mites are usually arranged on the lower part of the leaf plate, feeding on the sap of the plant - simply drinking vitality from it. At the same time the plant dries, becomes covered with spots, leaves are curled.
Immediately after detecting pests, spray the tomatoes. To do this, such drugs as "Alatar", "Biotlin", "Fufanon" are suitable. Anti-insect and effective folk methods: marigold infusion, infusion of onion gruel with husk and others.
Tomato diseases
The disease that causes leaves to twist in tomatoes - bacterial cancer. Ulcers appear on the leaf plates, and cracks on the stalks. The elevated parts of the tomatoes may become yellow and dry. The same symptoms can cause tobacco mosaic and tobacco necrosis. These viral diseases are caused by infected seeds or the remaining infection in the soil, and are also responsible for the folded leaves. Unfortunately, these diseases can not be treated, so the affected plants must be removed from the garden to protect healthy ones and burn them. It is easier to take preventive measures against these diseases: deep cleaning and digging the site after harvesting; choosing the right predecessor; seed and soil treatment before planting (Fitolavin-300).
Twisting the leaves of tomatoes does not always require treatment. Before sowing, planting, familiarize yourself with the varietal characteristics of the selected tomatoes: leaf curling may be the norm. For example, this feature is different tomatoes "cherry".
