The amaryllis (Hippeastrum x hybridum) blooms in large, trumpet-shaped flowers on 3-foot stalks, in shades of pink, orange, white and red. Some varieties are striped or have multiple colors. Amaryllis is easy to both propagate and care for and thrives in light shade in USDA Hardiness Zones 8 through 10, although the plants can be grown indoors in cooler areas. Plant amaryllis bulbs anytime between September and January.
Til the planting area to a depth of 6 inches. Add a 3-inch layer of compost to the soil and mix it in well using a long-handled gardening fork.
Add 2 to 3 lbs. of complete fertilizer (such as 6-6-6) per 100 square feet of planting area to the soil and mix it in well. Level the soil and water it until it is moist but not saturated.
Plant the amaryllis bulbs deep enough so that just the neck of the bulb is above the soil. Plant bulbs 15 inches apart. Water them again and keep the soil moist, but not soggy.
Spread a 3-inch layer of mulch over the planting bed. This will keep the soil moist and discourage weeds.
Fertilize the amaryllis plants twice during the growing season with a low-nitrogen fertilizer according to the rate suggested on the label.
Deadhead the amaryllis plant frequently. This involves merely cutting off dead and dying flowers prior to them setting seeds. As soon as a flower is fading, cut it off.
Dig up the bulbs in the fall after the leaves of the plant have turned brown.
Cut or break the small bulbs off the mother bulb and plant them in pots filled with potting soil or into the planting bed.
Cut the leaves back to 1 inch on the mother bulb. Cut the roots to within 2 inches of the bulb and replant it.
