Water ornamental onions once a week during spring and summer. Ensure that the soil is kept moist, but not soggy. During fall and winter, reduce the water amount to once every 2 weeks. Make sure that the soil is always slightly damp but never dry. It is important to note that ornamental onions may need more water during times of extreme heat.
