Cultivation of tomatoes brings a lot of trouble upon gardeners. Their leaves can blacken, become covered by dark stains, dry or twist. The last problem is noted at violation of the modes of humidity or temperature, excess of fertilizers, some diseases. To return tomatoes to life, it is necessary to establish the reason of twisting of leaves.
Most often twisting of leaves at tomatoes can be observed in the first weeks after landing of seedling when the plant takes root. Over time, in process of growth, leaves become straight. Twisting for this reason does not pose threat for plants.
Water mode
One of the reasons of twisting of leaves of tomatoes - shortage or surplus of water. In this case foliage twists along the axis, forming peculiar boat. The correct watering will help to solve problem. In hot weather the tomatoes need to be watered every evening, and in cool will do it every other day enough. At water shortage the leaves are restored long enough - about two weeks.
Temperature condition
At air rise of temperature to the level of +30-35 degrees and above tomatoes begin to consume more oxygen. For this reason the disintegration of nutrients goes quicker. Along with it at such temperature condition necessary substances begin to be acquired and collect much more slowly. Because of it leaves starve, as leads to their twisting. For solution at this reason the leaves of tomatoes can be sprayed with urea. For this purpose it is necessary to part 2 tablespoons of urea on water bucket, and then to oprysnut plants. Two days later it is possible to use weak solution of potassium permanganate. As a rule, in two days the leaves of tomatoes become straight. If on the street too hot, plants need to create artificial shadow, using lutrastit and also to air greenhouses if tomatoes grow in the protected soil.
Excess of fertilizers
Tomato leaves can twist at the excess content of fertilizers in the soil. At this problem the leaves become similar to mutton horn. If twisting of leaves is complemented with development enough powerful stepsons and stalk thickening, it demonstrates excess of nitrogen that harms plodoobrazovaniye. As a result tomatoes strongly increase green material. For reduction of amount of nitrogen it will be rather once abundant to water tomatoes to wash up top layer of soil. At the same time it is important that water has left the site, but did not stand on it. Otherwise tomatoes will suffer also from excess of moisture. Ashes introduction will help to reduce amount of nitrogen in soil. It is possible to scatter it directly under bushes of tomatoes.
Diseases of tomatoes
If leaves at tomatoes twist down, it can indicate defeat by bacterial cancer. At the same time, as a rule, the lower leaves grow brown and wither, and then dry up at all. On the lower part of scapes of leaves and stalks sores and cracks are visible. If to cut stalk, it is possible to see brown ring of sosudik that indicates bacteriosis. In this case plants cannot be cured, they should be uprooted and burned.
