If the leaves of tomatoes that were he althy and strong just recently curled up on your beds, this indicates that the plant is experiencing discomfort. The first step is to figure out what factors could have led to such a result.
Possible causes and solutions
1. Usually, this is how tomatoes react to violations of temperature and humidity. High temperature (above 35 degrees) is bad. With such heat, a rapid breakdown of nutrients occurs. The plant absorbs many times less nutrients and absorbs them with difficulty. Starvation of the leaves sets in, 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. Curled leaves of tomatoes that grow in greenhouses? In such cases, you need to ventilate the room to create a uniform temperature. Since the temperature underground is quite low compared to the surface heated by the sun, the plant begins to get sick.
3. Another reason why the leaves of tomatoes curl up may be due to bacterial cancer. Such a disease can be distinguished by the manifested sores and cracks on the stems. If the leaves of tomatoes turn yellow, wither and dry, then this can also be the result of a disease.
4. Too much zinc. Useful substances in unlimited quantities can be detrimental to such a plant. Signs of this problem include purple undersides of the leaves and curling edges.
5. excess manganese. Many gardeners use this fertilizer too often due to its availability and relative cheapness. In this case, the young leaves are wrinkled and have a brighter color than a he althy plant.
6. Too little fertilizer is just as bad as too much. If the tomato leaves are curled up, then this is a sign of calcium deficiency. Growth slows down, the leaves are deformed, and the fruits are affected by blossom end rot. Blossom rot speaks for itself. At first, light watery spots appear on the fruits, which gradually darken. When the fruit ripens, dead tissue forms under the stain.
7. Phosphorus starvation causes tomato leaves to turn gray-green, and also causes leaves to curl.
8. If young leaves are the first to suffer (roll down), then this indicates a lack of copper, boron or sulfur.
9. Aphid or whitefly. If, upon closer examination of the twisted leaves, you find thesepests, it is worth treating 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 curled up. Pay attention to the signals that the plant gives, try to decipher them correctly, then you can boast of the richest harvest.
