Growing cucumbers indoors allows you to get an early crop. After all, how pleasant it is to enjoy a salad of fresh cucumbers when there is still snow on the street. It is not easy to grow an early cucumber. It often happens this way: a healthy plant begins to hurt sharply, and the main symptom of this phenomenon is yellowing of leaves and fruits. Why do cucumbers turn yellow in the greenhouse and what should be done to prevent this process? Let's try to figure this out.
What can cause yellowing of the leaves and fruits of the cucumber?
Violation of growing technology is the main reason that cucumbers turn yellow. A favorable microclimate should be created in the greenhouse for the growth and development of bushes: sufficient lighting, stable temperature of air and soil, average air humidity, regular ventilation of the greenhouse. The water regime should also be strictly observed: drying of the soil instantly leads to wilting and yellowing of the plant.
If the soil in which the bush grows is poor in phosphorus, potash and nitrogen trace elements, then this also leads to the fact that the fruits of cucumbers turn yellow. To prevent this problem, at the beginning of each season, a number of fertilizers must be applied to the soil. Modern industry produces complex preparations for feeding cucumber, which include all the necessary useful trace elements. When applying fertilizers, you need to strictly adhere to the norms, since their excess can also adversely affect the vital activity of plants.
On hybrid varieties of greenhouse cucumbers, up to 150 ovaries can be tied. This leads to overloading the plant - this may also be the reason that the cucumbers turn yellow. In a greenhouse, to obtain high-quality fruits on one bush, it is enough to leave 23-25 ovaries, and the rest must be removed.
To obtain healthy cucumber bushes, it is recommended to change their growth places annually. Constant plant growth in the same greenhouse leads to soil depletion, infection by its infections, which causes cucumbers to turn yellow. Fruits under such growing conditions are less tied every season, bushes get sick more often, and productivity is minimized.
Pest insects - provocateurs of cucumber bush disease
Aphids, spider mites, sprout flies, cucumber mosquitoes are those insects that feed on the juice, shoots and fruits of the cucumber. The vital activity of these pests on the bushes leads to the fact that cucumbers turn yellow in the greenhouse, dry out and die. These species of insects breed very quickly. Appearing on one plant, in just a few days they hit all the bushes in the greenhouse. To avoid this problem, it is necessary to conduct regular inspection of the bushes and at the first detection of harmful insects treat the plants and topsoil with special preparations.
