Amaryllis ((Hippeastrum) is an attractive perennial with minimal foliage and bold flowers that is most often seen around the holiday season. It is common practice to toss the plant after its blooms have faded, but if stored properly amaryllis bulbs will continue to flower for several years. Storing the bulbs can also force them to produce a new wave of foliage and blooms, as long as you are careful to provide the right conditions.
Move the container to a dark and dry location with temperatures that range between 40 and 50 degrees F. This should be done after the blooms have faded.
Reduce watering gradually over the next three to four weeks until you are no longer offering any water at all.
Clip off the foliage within 2 inches of the top of the bulb after it has turned brown. Be cautious not to damage the bulb.
Place the container on its side in the same cool, dry location and allow it to remain there for six to eight weeks. After the rest period is over, the amaryllis can be moved back to a sunny windowsill and watered regularly again.
