What if the pepper leaves are curled in the greenhouse?

When growing bell peppers in polycarbonate greenhouses, the problem of leaf curling often arises. Why this is happening and what needs to be done, read on.

When greenhouse peppers curl their leaves, they try to identify the primary symptoms. This may be due to uneven development of seedlings, incorrect care.

Leaf deformation can be different. In one case, they curl along the main vein. Often, along with twisting, a change in shade or shape is noted. The plate is bent inward, outward, downward, upward.

In closed rooms, there is a lack of air. They are often dry and stuffy. Due to the dry air, the foliage curls inward like a boat and a spiral. Moisture evaporates rapidly from the surface of the deciduous mass. Leaves lose their firmness and density, which is especially detrimental to newly transplanted seedlings.

Plants can be saved by lowering the temperature. For prevention purposes, it is necessary to provide comfortable humidity in the greenhouse. To do this, place containers with water in several places.

Greenhouse plants suffer from hot indoor air. Often the problem is not solved by constant spraying and irrigation. The main reason is intense sunlight.

The plant experiences stress, signaling it by wilting and curling of foliage. In the evening, the temperature drops slightly, subject to the watering regime, the leaves unwind slightly. In such conditions, the root system is not able to independently compensate for the lack of evaporated moisture.

Leaf curling is characteristic when there is a lack of moisture. They wither and wither, drying out at the edges. Pepper belongs to moisture-loving crops, which is why it can react to even the slightest changes in conditions.

The solution to the problem will be to normalize the watering schedule. It is important to keep the soil moist indoors. If it is too hot in the greenhouse, watering should be done daily.

In small rooms, plants can be planted on a hydrogel. This polymer has the ability to accumulate liquid and release it as the soil dries out. It is introduced into the soil during planting, avoiding contact with the root of the seedling.

If the pepper leaves do not just curl up, but also darken, the greenhouse is too damp and an environment for infection has been created. The plant also suffers from excess moisture. Darkening indicates the development of fungus and root decay.

Rolling leaves is the first sign of a problem. When it spreads, neighboring bushes may suffer. In this case, you need to urgently take action. The disease affects weakened seedlings that lack calcium.

Plants often get sick and die without proper care. After transplanting into a greenhouse, you need to constantly look after them, not forgetting about the garter and the formation of bushes.

Often, the leaves are curled in a "boat" inward at the top, due to the uneven growth of the central vein of the leaf and the leaf plate. If you follow the rules of care, the leaves can take the correct shape.

It happens that the greenhouse is too rarely ventilated, they forget about watering at all and do not feed the soil. As a result, it is depleted, plants lack potassium, magnesium, phosphorus.

They solve the problem by introducing complex organic fertilizers. It can be wood ash, which is poured under each bush in the amount of 1 tablespoon, after which loosening and watering are performed.

Wood ash is also used for liquid feeding. In this case, it is stirred in water (1 glass per 10 liters), insisted for a day, poured half a liter under each bush.

It is important to provide the culture with an optimal microclimate and the necessary conditions for keeping. The leaf plates can be deformed due to the soil, which provokes diseases of the seedlings.

The soil in the greenhouse should not have an increased acidity level. This prevents the roots from absorbing nutrients. It is necessary to monitor the balance of trace elements. With their excess or deficiency, the leaves of the plants are folded.

• When the plates curl upward and the edges dry out and crumble, the pepper doesn't have enough potassium.

• With a phosphorus deficiency, the color turns purple, the shape resembles a "boat", pressing against the stem.

• In foliage with an excess of potassium and a lack of magnesium, the spaces between the veins turn yellow and darken.

• Lack of calcium is expressed in the rise of the edges and tuberosity of the plates, the gradual appearance of yellowish-brown spots.

The lighting should be adequate. And also a mistake is the lack of soil treatment. Because of this, pest larvae accumulate in the soil, which in the future will settle on plants and cause significant harm to them.

Moreover, considering that pepper is a capricious crop in terms of growing, you need to monitor temperature changes. With a sharp change in temperature, the leaves of the plant not only curl, but also fall off.

For root dressing, you can use saltpeter and potassium carbonate. Fertilizers are diluted with water (2 tbsp. L per 10 l) and applied to moistened soil.

The ground part of the pepper suffers from attacks of harmful insects, signaling the curling and wilting of the foliage. You can visually determine the cause of the lesion. Signs are cobweb, whitish bloom, yellowness of the leaf plates.

All this suggests that the culture was attacked by aphids, thrips, spider mites or whiteflies. You need to get rid of parasites with special means.

It can be chemicals, biologics, folk remedies. Effective drugs are Inta-Vir, Iskra, Kleschevit, Aktellik, Fitoverm.

If the lesion is large, it is advisable to remove the bush and cultivate the soil. Manually removing aphids or other pests is useless. This measure is ineffective and gives no results.

In order to increase the immunity of plants, they resort to the use of stimulants. Someone uses soapy water, onion peels, wormwood for this. Other gardeners use Corvitol, Immunocytofit.

Often the plant is attacked by apical rot and columnar. With phytoplasmosis, which occurs due to intense heat, the edge of the plate begins to corrugate. Then it bends up and turns yellow. In this case, you have to get rid of the affected bushes.

If the cause of foliage curling is associated with infectious diseases, use "Fitosporin". On its basis, you can make solutions for spraying bushes.

In difficult cases, it is better to use copper-containing substances. Suitable "Kuprozan", "Hom", copper oxychloride. For the treatment of powdery mildew, use "Fundazol", "Previkur", "Acrobat Ordon".

As folk remedies, you can use onions, garlic, whey. They are effective in the early stages of the disease.
