Watering Onion Plants
Watering is essential to all plants in your garden, and onions are no exception. Onions require regular watering, but too much water can cause issues. Even watering is the goal! The better care your onions receive during the growing season, the more likely you’ll have a bountiful harvest.

Water thoroughly after planting, and regularly thereafter, about once a week if there is no rain. Onions have shallow roots, so don’t let the soil at the base of the plants dry out and crack.
Overwatering is equally problematic. If leaves develop a yellow tinge, cut back on watering. The closer to harvest time, the greater the need for water, but watch the plants carefully—when the onion tops start falling over, stop watering and let the soil dry out before harvesting.
Note that sandy soils will require more water than loamy soils; onions will not grow well in clay soils because it will be too wet much of the time.
