Even the most experienced gardeners knowing everything about the correct cultivation of vegetables face problems from time to time. For example, sometimes they should observe that leaves at tomato are twisted. The experienced vegetable grower starts identification of the reason and only then in the beginning – its elimination. Treatment of tomato bush depends on the reason, and them can be a little.
Surplus of fertilizers
From the best motives, i.e. for the purpose of increase in future harvest, amateur gardeners introduce to the soil under tomatoes nitrogen fertilizers. They in the majority define high productivity. Meanwhile at excess of nitrogen in the soil there comes the return result – the plodoobrazovaniya does not occur. And process begins with twisting of leaves in tubules which soon dry up and fall down.
As a rule, along with the twisted leaves the excess of nitrogen is shown also in thickening of sectional stalk and abundant appearance and development of stepsons.
For the purpose of reduction of concentration of nitrogen in the soil you can once, but is abundant to water bushes of tomatoes with large amount of water. Thus you will wash out top soil. But at the same time it is necessary to meet one condition – water has to leave the site, without standing near plants (just dig stock groove). Otherwise your tomatoes will suffer also from moisture surplus.
Wrong watering
Leaves at tomato begin to be twisted both from excess of moisture, and from its shortcoming. To improve situation, to you it is necessary to stop temporarily in the first case watering of plants, periodically loosening the soil under stalk and mulching it in order to avoid formation of crust which will not pass air to roots. In the second case (at lack of moisture) increase frequency of watering or volume of water under each bush. At the same time it is also desirable to mulch the surface of the soil under bushes needles, large sawdust or cones.
Wreckers and viral infection
If you have noticed that leaves at tomato bushes were twisted, but at the same time you were not zealous with nitrogen fertilizers and correctly watered plants, break several twisted leaves, unroll them and try to consider whether you are not present in wreckers. If those are, address for consultation the expert in shop. He will advise what medicine to process bushes to get rid of wreckers. Usually recommend the insecticidal medicines Tanrek, Alatar, etc. If you nothing and nobody find in the twisted tomato leaves, most likely, you have faced viral disease of plants which, alas, cannot be cured. Exit in this case one: removal of sick bushes.
After manipulations with sick plants wash hands thoroughly before passing to healthy. And do not work with healthy bushes of tomatoes at all in the same gloves with which you touched sick bushes.
Attention! If at you big plantation of tomatoes, you can see the first symptoms of viral infection at plants (these are just the twisted leaves). The following manifestations of disease – abundant falling off of flowers, small ugly fruits (kind of wooden). Get rid of these plants without regret and never take from them seeds even if the viral infection was formed after emergence of fruits, in appearance quite healthy.
Trimming of leaves and pasynkovaniye
Prishchipyvaniye of separate branches at tomato bush and removal of unreasonably large number of the stepsons who have especially outgrown can cause twisting of leaves in tomatoes. Normal within week it is possible to cut off no more than 2 leaflets on plant. At more intensive cutting and pasynkovaniye the natural balance between roots and elevated part is broken therefore leaves are twisted.
