[header] How to care for bulbs [title] Water the bulbs. [step] You should water bulbs after planting them. This will help the plant develop roots and also set the soil around the bulb, eliminating air pockets. 
[substeps] Don't water shallowly as the bulb may be planted pretty deep and the water needs to soak the roots thoroughly. Add about one inch of water every week after the plant starts flowering if the rainfall is not adequate in your area.
