Growing nightshades doesn't require much effort. But even professional gardeners are faced with the problem of leaves curling on tomato bushes. Let's look at the main reasons and ways to solve this problem.
Violation of agrotechnical care
Sometimes, due to deficiency or lack of moisture, tomato leaves curl into a tube. Tomatoes are not a particularly moisture-loving plant, so you need to approach watering the plant with special care.
First of all, you need to adjust the frequency of watering. It is recommended to water tomato crops no more than 2 times a week. In this case, weather conditions must be taken into account. Water for irrigation should be settled and warm. It is not recommended to get water on the leaves of the plant. The best option is drip irrigation.
Temperature also affects the condition of leaves on tomato bushes. Due to the high air temperature, not only the leaves curl, but also the ovaries of the future harvest fall off.
This problem is solved by mulching the soil near the root system and constructing shading. You can use any dry grass for mulching. To create additional shading, a special green or brown mesh is sold, which is stretched over high poles.
Lack of microelements negatively affects green mass.Typically, the phenomenon of leaf curling occurs due to a lack of nitrogen. To solve this problem, it is necessary to use an infusion of wood ash for watering. It is diluted in the following proportions: 500 grams of dry matter per bucket of water. The solution must be left for 2 hours and can be used.
Infection of tomatoes with diseases
Infectious diseases can appear due to improper agrotechnical care. Most often, plants get sick due to high density.
When infected with bacterial canker, the leaves begin to wither, turn yellow and curl. To get rid of the disease, it is necessary to remove all infected leaves and spray the bushes with a solution of copper oxychloride. It must be aimed in accordance with the manufacturer's recommendations on the packaging.
When tomato bushes are infected with fusarium, the leaves that are located at the bottom of the bush curl and fall off, and the veins of the plant become discolored. You can get rid of this dangerous infection only by removing infected bushes so that the disease does not spread to healthy bushes. In this case, the place where diseased plants grow must be carefully treated with special antifungal professional preparations.
To prevent infectious diseases, it is recommended to take all measures, since many viral infections are practically incurable.
Insect pests
Particularly dangerous pests of tomatoes that cause leaves to curl include red spider mites, whiteflies and aphids. They suck the juice from the leaves, causing the leaves to curl and the plant to wilt.
To prevent the appearance of insects, it is necessary to carry out preventive spraying.You can use both specialized insecticides and folk recipes for this.
Of the folk recipes, the most effective are infusions of strongly smelling plants, which repel pests with their unpleasant aroma. For example, take 1.5 kg of wormwood and infuse it for 24 hours in 10 liters of water. Then the tomato bushes are sprayed.
Before starting any activities with plants, it is necessary to determine the cause of the problem. And only after that take active action.
