Dwarf amaryllis are flowering bulbs that produce flower stalks of up to 18 inches in height and produce four to six blooms atop each stalk. Their full size counterparts have larger bulbs that produce stalks up to 20 inches or more in height and up to eight flowers per bloom stalk. Dwarf amaryllis can be grown exactly like the larger form and are shown to best effect when they are planted en masse in garden beds or containers, or used as decorative indoor plants. Amaryllis are hardy in USDA Zones 8 through 10 and are grown as indoor plants beyond this range.
Plant dwarf amaryllis bulbs in the soil so that the tip of the bulb protrudes above the soil between one-quarter to one-half an inch. Bury the bulbs in nutrient rich soil that will drain easily, using fresh potting mix when you plant amaryllis in containers. Allow six to eight weeks for container grown indoor amaryllis to mature and reach bloom and up to three months or more for those grown outdoors in the garden soil.
Grow your dwarf amaryllis in direct sunlight or slightly filtered shade when it is not flowering. When in bloom, move potted amaryllis out of direct sunlight to preserve the bloom life.
Water your dwarf amaryllis to keep the soil lightly moist but not soaking wet at all times. Do not let potted amaryllis sit in a saucer full of water; always allow the pot to drain completely after watering to avoid rot.
Feed your dwarf amaryllis planted in the garden soil with a good quality granular bulb fertilizer twice per year in the spring and early fall according to the label dosing directions. Water in well. Feed potted amaryllis with a balanced water soluble fertilizer such as a 10-10-10 once a month diluted with water at 25 percent of the recommended dose.
Prune away individual blooms as they fade to make room for the fresh blooms. Cut down the flower stalk after all of the flowers on the top have bloomed and faded to make room for a second stalk. Cut 2 inches above the top of the bulb to ensure you do not cut into the bulb tissues.
