Why leaves are twisted in tomatoes: the main reasons

There is nothing more delicious than its tomatoes grown with love. Such vegetables will not only be tasty, but also useful. After all, if you grow vegetables for yourself, then, as a rule, do not use harmful insecticides. Yes, and with fertilizers apply very carefully, because their excess can begin to accumulate in the fruit, changing the taste is not for the better. In general, home-grown vegetables grown by own hands are the best.

Cultivation begins with the process of planting tomato seeds. The seedlings are then transplanted into a greenhouse or open ground (depending on climatic conditions). After a while bushes grow, flowers appear on them, and then small green tomatoes. It would seem that it is about to be able to harvest, but the trouble is that the tomato leaves are twisted. What should I do in this case?

Let's try to understand the reasons for this phenomenon. If you know what caused it, you can take some measures to prevent this process.

The first reason is rather banal: the plant is just hot, it lacks water. As a rule, in such tomatoes, the lower leaves do not twist, since they are shaded by the upper leaves.

The second reason is improper, excessive top dressing. Excessive nitrogen content in the soil leads to the fact that the stem of the bush becomes thick and powerful, but the leaves of tomatoes are twisted. This problem can be easily eliminated. To do this, several times the soil must be watered abundantly: water will wash away excess fertilizer. The main thing is not to overdo it, because stagnant water is highly undesirable: it can cause the process of putrefaction and infection with a fungus. If you are afraid to overdo with the "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, which leads to the fact that the leaves are twisted in tomatoes, is a black aphid. It's hard to find out when she just took a bush to herself. As a rule, this pest prefers to settle in the axils of the leaves, later moving to the leaves and stem themselves. Black aphids suck out all the juices from the plant, in exchange injecting a substance, because of which the leaves are twisted in tomatoes. Due to the fact that the pest settles in the sinuses, it is quite difficult to destroy it with insecticides: it will be necessary to carefully spray the entire bush, paying special attention to all the folds.

And finally, the most unpleasant reason - the virus is curly. This disease can affect not only tomatoes, but also other plants that are near. Cure the plant does not. The sick bush must be immediately removed from the bed, as it serves as the source of the virus.

How to recognize a virus of curl? According to the appearance of the tomato: the upper leaves of the bush twist, the central shoot stops in growth, the young foliage acquires a painful light green or yellow tint, the plant begins to lag rapidly in development from its brethren.

So, these are all the main reasons why tomato leaves can curl. Care for the plant carefully, observe all the rules of agricultural technology for this culture. Then this problem will bypass you.
