Diseases and pests which may affect cucumber
You can grow your young plants indoors for no more than 2 weeks before you are ready to plant them in soil. Be sure that the temperature is stable and there is no danger of frosts. You can also plant seeds directly in the garden, if the soil is well warmed. Separate your seeds by about 3-4 fee, or ground your future cucumbers in rows. And do not forget that some cucumbers varieties can be grown in container gardens.
Unfortunately these heat-loving plants suffer from many different pests and diseases. Aphids, pickle worms, mites, and cucumber beetles are the most common pests you may face with in your bed. Your plants may also suffer from such diseases as anthracnose, powdery mildew, downy mildew, bacterial wilt, and angular leaf spot.
With the appearance of seedlings, look for cucumber beetle, which attacks young plants. If your cucumber is infected with bacterial wilt, it will droop and die eventually.
But remember that chemical pesticides in your garden may be harmful for the bees that fertilize your plants. Chemical pesticides can also be harmful for the other beneficial insects and soil organisms in your garden.
