Water the spring-flowering bulbs immediately after planting them. This encourages them to grow roots. The sooner the roots develop, the better the flower bulb can tolerate cold and even freezing temperatures. Flower bulbs in pots will also need water during the period following planting because the soil in the pots dries out quicker at that time.

Summer-flowering bulbs need even more water just after planting. Keep the soil in the garden or in the pots/plant containers moist after planting the bulbs.
