There is nothing tastier than your own tomatoes grown with love. Such vegetables will be not only tasty, but also he althy. After all, if you grow vegetables for yourself, then, as a rule, you do not use harmful insecticides. Yes, and you are very careful with fertilizers, because their excess can begin to accumulate in fruits, changing the taste for the worse. All in all, home grown vegetables are the best.
Growing begins with a process such as planting tomato seeds. The 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 will be possible to harvest just about now, but the trouble is that the leaves of the tomatoes are curling. What to do in this case?
Let's try to figure out why this phenomenon can occur. If you know what caused it, then you can take some measures to prevent this process.
The first reason is rather banal: the plant simplyhot, 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 incorrect, excessive feeding. Excessive nitrogen content in the soil leads to the fact that the stem of the bush becomes thick and powerful, but at the same time the leaves of the tomatoes curl. This problem is fairly easy to fix. To do this, you need to water the soil abundantly several times: the water will wash away the excess fertilizer. The main thing is not to overdo it, since stagnant water is highly undesirable: it can cause the process of decay and infection with a 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 for curling the leaves of tomatoes is the black aphid. It is difficult to detect when she has just chosen a bush for herself. As a rule, this pest prefers to settle in the axils of the leaves, later moving to the leaves and stem themselves. The black aphid sucks all the juices out of the plant, instead injecting a substance that causes the leaves of tomatoes to 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 curl virus. This disease can affect not only tomatoes, but also other plants that are nearby. There is no way to cure a plant. A 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 curl virus? According to the appearance of the tomato: the upper leaves of the bush are twisted, the central shoot stops growing, young foliage acquires a painful light green or yellow tint, the plant begins to rapidly lag behind its counterparts in development.
So, these are all the main reasons why tomato leaves can curl. Take care of the plant carefully, follow all the rules of agricultural technology for this crop. Then this problem will bypass you.
