Unlike some other bulbs, amaryllis do not require a rest or dormant period. They will bloom again if allowed to continue to grow. But bloom time can be controlled by allowing the bulb go dormant (stop growing) for a period of time. During this resting period (dormancy), plants use very little of their energy reserves.

How do you know if amaryllis is dormant?

Amaryllis Dormant Period

For winter or early spring bloom, gradually reduce watering the bulb less in late summer and allow the soil to dry almost completely. The bulb is fully dormant when the leaves yellow and die back completely, usually in late summer or early fall.
