In central Georgia, you can overwinter the bed with a heavy layer of mulch for winter protection. When growing amaryllis as a pot plant in the home, a southern window exposure provides ideal conditions for sun-loving amaryllis. An eastern or western facing window is second best, while plants grown in a northern window may require supplemental light. Light from a 100-watt bulb provided for a few hours each evening should be sufficient. You can expect plants to bloom six to eight weeks after planting indoors, depending on temperature, light and variety.
More time is required for plants to bloom outdoors.
Fertilization Fertilization determines the size and quality of the flowers and foliage. Any soluble or liquid fertilizer is satisfactory for pot plants, but use it at half the recommended rate. Apply liquid fertilizers at five to six-week intervals. A bulb booster type fertilizer can also be used. Avoid applying excess nitrogen because it promotes vegetative growth and reduces flowering.
