Summer residents often do not pay attention to this symptom, and when they realize the problem, it is already too late.
In open ground, cucumber leaves turn yellow. Many attribute this to a lack of moisture, so they begin to water intensively.
However, there may be a more serious problem behind the change in the color of the green mass of the plant. But the exact cause is determined by the gardeners based on the age of the plantings.
Nitrogen deficiency
At an early stage of development, cucumbers may lack nitrogen. The macronutrient is responsible for the health and proper development of green mass.
This can be corrected by adding mineral fertilizers. Organic matter is also an excellent source of nitrogen, but the fertilizer will not be absorbed in a short period of time.
Disease
Powdery mildew can ruin the entire crop. If the plant is mature and more than 50% of the bush is affected, then it is unlikely that you will be able to help the plant.
First, you need to remove all damaged shoots. Second, add mineral fertilizer. There are no guarantees for recovery, but there is a chance.
Cold snap
The weather also makes adjustments to the fate of the cucumber harvest. At low temperatures, the plant stops absorbing nitrogen, the leaves turn yellow, photosynthesis stops and the bushes die.
