There is nothing tastier than your tomatoes grown with love. Such vegetables will be not only tasty, but also healthy. After all, if you grow vegetables for yourself, then, as a rule, do not use harmful insecticides. And fertilizers are handled with extreme caution, because their excess can begin to accumulate in the fruits, changing the taste not for the better. In general, home-grown, home-grown vegetables are the best.
Growing begins with a process such as planting tomato seeds. 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 would be possible to harvest soon, but the trouble is that the leaves of the tomatoes are twisting. What to do in this case?
Let's try to understand the reasons for this phenomenon. If you know why it happened, you can take some measures to prevent this process.
The first reason is quite commonplace: the plant is just hot, it lacks water. As a rule, in such tomatoes, the lower leaves do not curl, as they are shaded by the upper ones.
The second reason is improper, over-feeding. Excessive nitrogen content in the soil causes the bush stalk to become thick and powerful, but the leaves of the tomatoes are curled. This problem is easy enough to fix. To do this, you need to water the soil abundantly several times: water will wash off the excess fertilizer. The main thing is not to overdo it, since stagnation of water is extremely undesirable: it can cause the process of decay and infection with the fungus. If you are afraid to go too far with "water procedures", just 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.
The third reason that leaves in tomatoes twist is black aphid. It is difficult to find when she just took a fancy to a bush. As a rule, this pest prefers to settle in the axils of the leaves, later moving to the leaves themselves and the stem. Black aphids suck out all the juices from the plant, instead injecting a substance, due to which the leaves of the tomatoes curl. Due to the fact that the pest settles in the sinuses, it is quite difficult to destroy it with insecticides: you will have to carefully spray the entire bush, paying special attention to all the folds.
And finally, the most unpleasant reason is the curly virus. This disease can affect not only tomatoes, but also other plants in the vicinity. There is no way to cure the plant. The diseased bush must be immediately removed from the garden, as it serves as a source of the spread of the virus.
How to recognize the curly virus? In appearance of the tomato: the upper leaves of the bush are curled, the central shoot stops growing, the young foliage acquires a painful light green or yellow hue, the plant begins to rapidly lag behind its counterparts in development.
So, these are all the main reasons why tomato leaves can curl. Care for the plant carefully, follow all the rules of agricultural technology for this crop. Then this problem will bypass you.
