Growing Hints: Amaryllis couldn't be easier to grow. Most garden and home centers offer them for sale during the winter season when they are commonly grown to bloom for the holidays. Although not necessary, soaking the root end of the bulb in water the night before planting will give it a faster start. Place the potted bulbs in a sunny window sill and keep soil moist (not wet) until blooming. Tall plants may need staking. Continue to water until the leaves start to turn yellow and die back. Cut them down and cease watering for 12 weeks. The plant can be brought out of dormancy again after this rest period, but cheaper bulbs may fail to flower a second time or flower less successfully. High quality amaryllis bulbs can produce many flowers at a time for as long as 75 years. good luck.
The secret to getting amaryllis bulbs to rebloom year after year lies largely in summer care after flowering. Remove the faded flowers and stalks as soon as they are finished blooming, but do not cut off the leaves. Set the pot on a sunny windowsill and water as needed. When warm weather arrives and all danger of frost is passed, set the bulb, container, and all in the flower garden. Choose a location that is somewhat protected and receives morning light. You can set the pot in the ground so that the rim is at ground level.
During the summer, continue to water the plant as needed and feed it every two weeks with a soluble houseplant fertilizer. Gradually withhold water before freezing weather in the fall. When the foliage has died down, trim it off and take the pot to a cool, dark basement (40 to 50 degrees F if possible) and place it on its side. The bulb needs to sit and rest for six weeks before you try to rebloom. Because it takes approximately six weeks from planting to bloom time, you can decide when you want the bloom to occur and then count backward to determine the planting time. During the rest period, do not water the plant. As the leaves dry, cut them off.
