If on your beds suddenly twisted tomato leaves, which recently were healthy and strong, then this indicates that the plant is uncomfortable. First of all, you need to understand what factors could lead to such a result.
Possible causes and solutions
1. Typically, tomatoes respond to temperature and humidity disturbances. Bad effect of high temperature (above 35 degrees). With such heat, the rapid decomposition of nutrients occurs. The plant absorbs many times less nutrients and hardly assimilates them. There is a starvation of leaves, and, as a result, the plant dries up, loses leaves and flowers. Due to too frequent and abundant watering, the plant develops a weak root system, which also entails twisting of the leaves.
2. Are the leaves of tomatoes that grow in greenhouses curled? In such cases, you need to ventilate the room to create a uniform temperature. Since the underground temperature is quite low compared to the surface heated by the sun, the plant begins to hurt.
3. Another reason why leaves are folded in tomatoes may be a defeat of bacterial cancer. You can distinguish such a disease by manifesting sores and cracks in the stems. If the leaves of the tomatoes turn yellow, wilt and dry, this can also be the result of the disease.
4. Too much zinc. Beneficial substances in unlimited quantities can be detrimental to such a plant. Signs of the appearance of such a problem are the color of the lower part of the leaves in purple and the edges are bent.
5. Excess manganese. Many gardeners use this fertilizer too often because of its availability and relative cheapness. In this case, the young leaves are wrinkled and have a brighter color than a healthy plant.
6. Lack of fertilizer is as fatal as its excess. If tomato leaves curl up, then this is a sign of calcium deficiency. Growth slows down, leaves are deformed, and fruits are affected by apical rot. Vertex rot speaks for itself. At first, light watery spots appear on the fruits, which gradually darken. When the fruit ripens, a dead tissue forms under the stain.
7. Phosphorus starvation leads to staining of tomato leaves in gray-green color, and also causes folding of leaves.
8. If the first thing young leaves suffer (curl down), then this indicates a lack of copper, boron or sulfur.
9. Aphids or whiteflies. If, upon a more detailed examination of twisted leaves, you find these pests, then it is worth processing the tomatoes with a special solution as soon as possible.
In any case, all kinds of fertilizers should be used in optimal proportions.
All of the above reasons allow us to give a detailed answer to the question of why tomato leaves twisted. Pay attention to the signals that the plant gives, try to decipher them correctly, then you can boast the richest harvest.
