Problems in cucumber growing
Consider that you can avoid many diseases if you buy resistant varieties. Some of them are resistant to cucumber mosaic, downy mildew, powdery mildew, anthracnose, angular leaf spot, scab, etc.
One more way to avoid such troubles, as disease and pest is to rotate crop with herbs, annuals, and other vegetables. If your cucumbers have already suffered from pests or diseases, the best thing you can do is to identify and treat the problem as quickly as possible.
If your cucumbers look healthy but do not produce fruit, the plants may be suffering from a lack of pollinators in your garden. Try no to use chemicals in the garden, especially insecticides.
Cucumber bitterness is very common trouble. This bitterness is caused early in the plant’s development by terpenoid compounds that give a bitter flower to the entire plant. Typically, the bitterness accumulates at the stem and below the surface of the cucumber’s skin. But unfortunately, this is a genetic problem. The latest hybrids seem to have less problems with bitterness. Additionally, remember to grow your vines in the proper area, with plenty of sun. Avoid over watering and use organic compost.
