Why do cucumber leaves wither in a greenhouse: how to identify the cause
It would seem that a greenhouse is a wonderful place with a favorable environment for growing plants, but growing cucumbers, on the contrary, the plants disappear in the greenhouse.
Leaves can wilt in cucumbers for the following reasons:
- Drought or insufficient watering;
- Fungal and viral diseases of plants;
- Improper care and nutrition of crops.
The most common reason for the wilting of cucumber leaves in a greenhouse, as in an enclosed space, is excessive hot weather and insufficient watering of the plants. Plants do not get enough moisture and begin to wilt and dry out.
Improper cucumber care, such as watering directly onto the leaves, fertilizing with harsh chemicals and improper weaving, can all destroy the plant, starting from the leaves.
The most dangerous enemy for cucumber leaves are fungal diseases and viral diseases, which can multiply throughout the garden and enter greenhouses through sand on shoes, dry plants, which often moisten the soil. Sometimes the cucumber leaves themselves do not just wither, but also dry up, forming a dry and yellow leaf.
How to find out why cucumber leaves wither in a greenhouse and dry up
The leaves of cucumbers can wither from the heat, in this case they can be revived with ordinary watering, but if the leaves still wither and begin to dry, the plant must be processed.
Why cucumbers wilt and then dry:

After detecting unfavorable factors, they must be eliminated, and the plants and soil must be treated with a special solution.
Why do cucumber ovaries wither in a greenhouse?
Cucumber is a very delicate plant from root to ovary, therefore cucumber ovaries often suffer. This part of the plant is very rarely damaged by pests, mainly the ovaries suffer from improper plant care.
If absent, the reasons for the wilting of the ovaries are as follows:
- Dense planting;
- Stopping growth;
- Incorrect plant feeding technology;
- Weak pollination.
With a dense planting, cucumber ovaries weaken, the flow of oxygen to them deteriorates, moisture and flowers evaporate poorly. Without blooming, they begin to dry, as a result, the fruit does not grow. The growth of a cucumber grown in a greenhouse stops growing after a strong drop and on the street, when herbicides get on the plant when cultivating the land.
Fertilizing the rhizomes of cucumbers, which is carried out with chemical preparations, if carelessly leads to wilting of the leaves, if the drug gets on the leaves and lashes of the plant.
Growing cucumbers in a greenhouse, very often the ovaries wither from insufficient pollination. The flowers seem to have started, but they cannot open. Improving the pollination of cucumbers will help their correct sowing from several varieties or planting with dense planting.

If cucumber ovaries dry up in a greenhouse, the plant must first of all be saturated with moisture and dry ovaries removed. You need to closely monitor the temperature in the greenhouse. If the reason for the wilting of cucumber ovaries is insufficient pollination, insects must be urgently admitted into the greenhouse.
When the whips have withered on the cucumbers, only spraying the plants with special preparations will help. Fungicides such as Topsin, Previkur, Bayleron.
