Amaryllis is a large lily with flowers up to 6 inches across. Also known as Bella Donna lilies, amaryllis is available in red, white, pink, magenta and yellow. It originated in the Andes Mountains and is a tropical, frost-sensitive plant. The bulb will not survive freezing temperatures. Grow amaryllis in the garden in USDA Hardiness Zone 8 and store inside before the first frost.
Select a sunny location that gets afternoon shade. Dig the area and add compost and other necessary soil amendments depending on the soil type. Amaryllis prefers rich, well-drained soils. Add one part sand and one part organic matter to one part soil if the soil is clay-like.
Trim brown and dry roots off the bottom of the bulb.
Plant the bulb so that the bottom 2/3 is under ground and the rest is above ground. Space the bulbs 3 to 4 inches apart.
Water and feed as you would other flowers. Ensure that the bulb gets about 1 inch of water per week. Fertilize once a month with water soluble plant food per package directions.
Remove the flower stalk after it has bloomed, if desired. Allow the leaves to remain on the plant until they have completely yellowed.
Dig up the bulb several weeks before the last frost in Zone 8. Contact the closest university agricultural extension or talk a nursery staff member for the dates. Store the bulb in a cool, dark place until spring.
Replant the next spring when the days are warm and it's above 60 degrees F at night.
