Cucumbers whose leaves turn yellow require thorough analysis and quick action. At the beginning you should find the cause of this phenomenon and make any changes in cultivation and use spraying. You don’t have to run to the garden store. You will find everything you need in the first aid kit.
The yellowing cucumber leaves not only look unsightly, but also negatively affect the quality of crops. This problem applies to plants grown in the ground, greenhouses, plastic tunnels and can occur at any stage of development.
To start with, it is worth considering why yellow discoloration occurs on cucumbers. Well, chlorophyll is responsible for the green color. If it is not enough, then yellowing occurs. What are the reasons for this?
They should be seen in incorrect cultivation. For example, a small amount of light causes the loss of the color of the leaves. The same happens when plants grow on heavy soils or do not have enough minerals, i.e. nitrogen, potassium, magnesium.
Cucumbers do not like drought nor excess water. Incorrect irrigation also negatively affects their condition.
Yellow spots between the nerves of leaves and the coating from below can be a measuring powdery mildew. In turn, yellowing, dry, withered leaves are a symptom characteristic of fusariosis, while the cucumber mosaic virus is manifested by their deformation and a yellow -green mosaic.
It is also possible whether spider mites for yellowing parts of these plants. In this case, specialized spraying must be used.

Cucumbers are included in photophilic plants, so they should be provided with 6-8 hours of exposure to sunlight. This is very important, especially during their growth.
Cucumber leaves will not yellow if we plant them on fertile, permeable, slightly acidic soil with a pH of 6.0 to 6.8. In the case of heavy soil, we recommend the use of compost or peat substrate to improve its structure and water retention.
Let’s also take care of regular, but moderate watering. Let’s irrigate the plants in the morning, watching in the list. By soaking, fungal diseases may develop. A good solution is the use of drip irrigation or Seking hoses.
Fertilization is also extremely important in maintaining the green color of the leaves. It is worth using multi -component fertilizers with low chloride content or special products for pumpkin vegetables. Biohumus and nettle extract are natural nutrients.
Yellow cucumber leaves, it is worth spraying with the agent from hydrogen peroxide. This aseptic product from the first aid kit oxygenates the roots and fights fungal diseases. How to do it?
Just dilute 50 ml of hydrogen peroxide in 150 ml of boiled water. Pour this mixture into a bottle with an atomizer and spray it with yellow cucumber leaves. Thanks to it, these parts of plants will quickly regain a healthy appearance, and the specimen itself will have better conditions for development and regeneration.
Remember, however, to use this spraying together with the above care rules. Only then will we see good quality crops.
