Include some flowering herbs or annuals in your vegetable garden to attract beneficial insects to your garden. Some vegetables such as cucumbers and zucchini have both male and female flowers and require a visit from a bee or other pollinator to move the pollen from the male to the female flower so that fruit can develop.
Seedlings started indoors need good air circulation. Use a small fan on a low setting to simulate the outdoor breezes. You may need to water more frequently. If you don’t have a small fan, gently brush your seedlings with your hand every day – you should have seedlings that are stockier and sturdier.
