Lack of light.

But if even in the conditions of an ideal summer the tops of cucumbers turn yellow, what should I do? Examine the beds - do they look like dense thickets? It is difficult for the rays of the sun to get through the thick of the plants, so some of the leaves will turn yellow. Just remember to remove them in time.

Too much sunlight.

The tops dry up and from the scorching sun. Grow cucumbers in a greenhouse or in the partial shade of other plants, following the rules of regular watering with warm water. So, you save the bushes and get a generous harvest.

Make a bed for cucumbers in the shade, cover with covering material, or plant in a greenhouse.

Lack of pollination.

In the greenhouse, plants often suffer from insufficient pollination, which leads to a deterioration in the formation of ovaries. Bushes are also affected by harmful insects and diseases.

Beginners often water cucumbers with cold water, which negatively affects their growth and development. and irrigate this crop in a greenhouse should only be warm water at least 2 times a week or more often.

Aphids and fungal infection.

One of the reasons may be aphids and various insects.

• Effective against insects decoction of onion peel, which should be infused during the day. Dilute it with water and spray the leaves.

Cucumber leaves turn brown and wither in the greenhouse due to aphids. These pests feed on plant sap, located on the back of the leaf. The bush begins to suffer from a lack of moisture and dries, which leads to the death of the fruit. How to protect your crop?

• Helps well with aphids hot pepper infusion and garlic, as well as industrial preparations, for example, Fitoverm.

The main thing is to notice in time the cause of the withering of the green mass.

Lack of minerals.

Why does cucumber tops turn yellow if the plants receive enough moisture and light? In addition to various pests, there may be several more reasons.

For a good harvest of cucumbers, you need to do it, but this is not enough. The reason lies in the earth, more precisely, in the lack of minerals in it. As a rule, vegetables are sensitive to low nitrogen content in the soil.

Both the leaves and all the lashes of the bush turn yellow. The shape of the fruit becomes twisted.

• In order to prevent deformation of cucumbers, seedlings are recommended a few days before planting in the garden feed with complex fertilizer.

• Urea with the addition of humus.

• Good effect on cucumbers also infusion on broken hay, which must be kept in a bucket for about 2 days. Spray them with bushes should be 1 time per week for a month.

Natural aging.

In July, the tops turn yellow for natural reasons, since in the process of life the plants age, photosynthesis gradually stops and the greens die off. By the end of the month, as a rule, gardeners harvest most of the crop, and yellowness does not bother them.

How to properly water cucumbers.

Cucumber is a juicy vegetable, so the lack or excess of moisture adversely affects its quality. When grown outdoors, it is subject to adverse environmental factors, including rainfall.

It is unreasonable to water the bushes in the sun, so prepare buckets of warm water for the evening when the sun disappears.

In the event of drought, the root system of plants will make its way to the surface of the soil in search of liquid, which will lead to the death of leaves and ovaries. But the rainy summer harms the cucumbers no less - because of the washing out of the earth, the roots die, which is why the leaves turn yellow.

Do not water cucumbers with cold water, irrigate only with warm water.

1. Experienced gardeners advise to soak loaf of black bread in water overnight.
2. In the morning, knead the product and pour a little ordinary iodine.
3. Take 1 liter of the mixture and dilute it with water, then spray the cucumbers. Such a simple and effective dressing rejuvenates the bushes.

2. Close the lid and leave for a few days in the sun.
3. Add a little to the finished infusion ash and stir.
