Cucumbers can turn bitter and radishes get hotter when they don’t receive enough water. Sweet corn and lettuce have more shallow root systems, so they are more sensitive to drought or lack of watering. Celery, artichokes, and asparagus are a few crops that need a lot of water. Beets, peppers, squash, tomatoes and melons all appreciate moderate watering. Then there’s herbs like garlic, marjoram, oregano, and thyme which all can survive on very little water. In general, regular and consistent watering for all vegetable crops is most important from the set of blossoms through harvest time. Although some fruits and vegetables thrive with frequent watering, there is such a thing as too much water. This can produce bland, more tasteless fruits.
