Do you know why yellow leaves of cucumbers?

Often, owners of household plots are forced to save their own crop, which can "die" due to various circumstances, such as changing weather conditions, pests of plants and so on. Very often truck farmers have to observe how yellowish leaves appear on the leaves of cucumbers. Of course, this is a sign that the vegetable is "sick" and needs help.

However, not everyone knows why cucumber leaves turn yellow. Experts explain this phenomenon for a variety of reasons. Indeed, why do yellow leaves of cucumber? First, because of the lack of moisture at high temperature. Secondly, because of excessively low temperatures at night, which are often accompanied by frost. Third, the "false berry" may lack minerals and trace elements. Fourth, cucumbers can be affected by fungal diseases and other parasitic organisms.

Consider some of the reasons why the leaves of cucumbers turn yellow, in more detail.

Experienced gardener perfectly understands that the above vegetable loves moisture, and the slightest deficit can lead to the formation of yellowness on the ovaries and fruits. The wrong choice of the water temperature for irrigation can lead to the same consequences.

Therefore, experts recommend using exclusively cushions for watering cucumbers . Frosts, which often occur in early spring, can also cause a discoloration on the ovaries.

Why do cucumber leaves turn yellow in other cases? The above plant is quite susceptible to various diseases, for example, such as powdery mildew. First, small spots of light shade are formed on the leaves, subsequently they increase in size and are transformed into a white coating. After a certain time, it acquires a yellow "ornament", after which the leaf withers. This is a clear sign that cucumbers are affected by a fungal disease. The problem is exacerbated by the fact that the microorganism is extremely prolific, so the likelihood that it will reappear next year is extremely high. To minimize such risks, experts advise to carry out the procedure of crop rotation and choose varieties with increased immunity to fungal diseases.

Very often even the cucumber seedlings turn yellow leaves. What does this show? The fact that the plant lacks trace elements, in particular, nitrogen. To solve this problem experts advise to carry out fertilizing. As a rule, it is done four times a season. During the flowering period (1 time) and during fruiting (3 times), the plant is further enriched with urea, potassium sulfate solution, superphosphate and mullein composition.

Another dangerous bacteriological disease for "false berries" is fusarium wilt. In this case, the toxins produced by the fungus penetrate so deeply into the capillaries that the cucumbers immediately turn yellow leaves and fruits. In the end, a plant grown in a greenhouse, dies.

This vegetable is often affected by root rot. The above-mentioned "ailment" is a serious threat to him: first the cucumbers turn yellow, and then the rest.

Experts in the fight against fungal diseases recommend the use of chemicals.
