If you're hoping to have your Amaryllis in full flower around holiday time, you need to plan ahead because Amaryllis bulbs need a rest period before they’ll bloom again.
- Around mid-August, begin withholding water and fertilizer and move the pot into a cool room (55° to 60°F is ideal, but no colder than 50°F).
- The leaves will begin to yellow, then wither and die back. At this point, you can cut them back to within about a half-inch of the top of the bulb.
- Let the pot stay in this cool, dry storage for about two months. Check the bulb occasionally, looking for any signs of new growth.
- After ten weeks or when you see a shoot emerging (whichever comes first), it's time to bring the pot back into the warmth and light.
Cut your Amaryllis back to encourage new growth, and a new bloom.
- For best results, repot the bulb in a container that's about twice the diameter of the bulb, using fresh, moist potting soil. Set the bulb in the pot so that the top third of the bulb is above the soil line.
- Keep the pot in a sunny window. Water the soil thoroughly, then let the soil surface dry out before watering again. Keep the plant in a sunny window, rotating the pot occasionally to keep the flower stalk growing straight (otherwise it will lean toward the light). In a few weeks, you'll have a reblooming Amaryllis!
You can repeat this process indefinitely, and provided you give it the required conditions the bulb should continue producing flowers each year.
