Amaryllis plants can be grown outdoors in Zone 9 to 11, but they are more commonly grown as houseplants. They are popular gifts for Christmas and Valentine’s Day because of their cheerful red, pink or white flowers. The trumpet-shaped blooms are 8 to 12 inches across and stand above the foliage on stiff upright stems. If you receive an amaryllis as a gift, you can make it bloom again by following a few easy steps.
Use hand pruners to remove the flower stems after your amaryllis stops blooming. Do not remove the leaves because the plant needs them to produce food for the next season.
Continue watering the plant regularly. Use liquid fertilizer every 4 weeks following the manufacturer’s directions.
Move the amaryllis in its container outside after the danger of frost is past. Set in a shady area for a week to harden off and then move it a sunny area.
Leave the amaryllis in its container in the sun, and continue watering and fertilizing through the summer and fall.
Move the amaryllis in its container inside before the first frost of the winter. Set it in a cool dry location for 8 to 12 weeks so the plant will go dormant.
Cut off the dead leaves and repot the amaryllis bulb in fresh potting soil. Use a larger pot if necessary. The pot should not be more than 2 inches deeper than the bulb is tall, and not more than 2 inches wider than the bulb.
Place 2 inches of potting soil in the bottom of the pot. Set the bulb in the pot and fill around the bulb with potting soil, leaving the shoulders of the bulb above soil level.
Water lightly until the plant begins to sprout, then resume regular watering and fertilizing. The plant should bloom again in 4 to 6 weeks.
