Each amaryllis bulb will become a breathtaking bouquet of blooms within four to eight weeks after planting. Expect one to three stems per bulb, each with three or more flowers.
If not pre-planted, plant your bulb in a 6" to 8" pot with drainage holes, using a houseplant potting mix. Leave the neck of the bulb above the soil surface. Water thoroughly. Avoid getting water in the neck.
Place the pot in a sunny location at room temperature. Water sparingly until about 2" of leaf or flower stem has emerged from the bulb, then water regularly to keep soil moist. Use a stake, if needed, to support the stalks. Cool, 55 to 65 degrees F temperatures and indirect light will prolong flowering.
Snip off faded flowers, but leave the stalk and foliage intact. Remove the stalk when it yellows. Continue to water. Fertilize monthly. The pot can be moved outdoors once danger of frost has passed. In late summer, stop watering and let the foliage die back. Store the bulb at 50 to 65 degrees F in a dark and dry place for at least eight weeks. Repot and resume watering about four to eight weeks before you want flowers again.For more details, read the article, Amaryllis Care.
