Amaryllis have become increasingly popular holiday gift plants, undoubtedly because the bulbs bloom very freely indoors and they are affordable. Amaryllis are not difficult to grow and may be brought into bloom every year if the plants are treated correctly. To understand the process, it may help to understand the plant and its native environment.
Saving the Amaryllis!
Thoughts from the Cottage…
Amaryllis are bulbs of the genus Hippeastrum that are native to tropical and subtropical areas of the Americas. Some species grow in rock crevices in savannas that have distinct dry and wet seasons; others grow in high plateau regions that have cool weather for most of the year. One species from Brazil is epiphytic and grows in trees in mountain forests with no soil around the roots. Many species have been hybridized to produce today's hybrids, and most of these species experience warm, humid conditions with abundant rainfall for most of the year and a short, cooler dry season. To make your amaryllis bloom again, you simply have to mimic the conditions that nature provides.
Keep it cool through the holidays
Enjoy your amaryllis for the maximum time possible by placing it in a location with diffuse light and cool indoor temperatures in the 60°F range. Keep it barely moist. When you water, be careful not to get the portion of the bulb that sticks above the soil wet. If you have a large bulb, you may get two or three flowering stalks that bloom over a period of several weeks.
When the last flower has faded on each of the flower stalks, cut the flower stalk near the top of the bulb. Be careful not to injure the leaves or any emerging flower stalks. Don't be alarmed if a large amount of sap runs out of the hollow flower stalk when you cut it. This is normal if the plant has been well watered.
It's now late winter, and your amaryllis is now in its growth phase. The main objective is to encourage leaf production that will help the bulb bulk up for next year's flowers. It's hard to give your amaryllis too much sunlight at this time of the year. Move it to the sunniest location that you can manage. A sunroom or greenhouse space is best, but a south-facing window will work until spring comes. Fertilize it monthly with a liquid fertilizer, and never allow the soil to dry out completely.
Cut the flower stalks
As soon as the weather all threat of frost is gone, move your amaryllis outdoors. Don't be alarmed if many of the leaves wither and die in the adjustment period. Older leaves will die and new ones will grow. Choose a sunny area where you can water the plants daily. A deck or patio works fine, and the glossy strap-shaped leaves are a good textural foil for many other plants. Fertilize the plants every two weeks with a liquid fertilizer or apply a slow release fertilizer.
If you want flowers for the holidays, you'll need to begin its dormant period by mid August. Withhold water, and move the pots to a location where they can be kept around 55°F. Most people don't have a space that they can keep this cool at the height of summer, so you might have to let the seasons determine bloom time for you. You can leave your amaryllis outdoors well into autumn. If you do, stop fertilizing it in late September and bring it indoors before the end of October or earlier if a heavy frost is forecast. You can bring it indoors in the pot or remove the bulb from the pot and wash the soil off the roots if you like at this time.
Amaryllis usually lose all or most of their leaves during their dormant period, although it is not necessary for all the leaves to wither for the bulb to reach complete dormancy. Keep the bulb on the dry side. Check the bulb every week; after eight to ten weeks of cool storage, you should notice the tip of the new flower stalk emerging from the bulb. If you shift the bulb to a warm spot (70-80°F) for three weeks, you will encourage leaves to emerge at the same time the flower stalk is developing, but a warm treatment is not needed for floral development. You can repot the bulb in fresh soil at this point. Be careful not to bury the bulb too deeply. At least one third of the bulb should be visible above the soil surface. Don't plant the bulb in a pot that is any more than two times the diameter of the bulb. When you repot it, you may notice smaller side bulbs that can be broken away from the main bulb. These can also be potted and grown on in a sunny spot. They will not bloom this year, but may bloom after two or three years of growth.
Water your amaryllis thoroughly right after you repot it, and allow the soil surface to dry a bit before watering it again. Place it in a warm sunny spot to stimulate root growth. If you try to re-bloom your amaryllis in dim light conditions, the flower stalk will grow long and your amaryllis will be more prone to breakage or tipping. Wait until the first flower has opened to move the plant to a location with subdued light and cool temperatures to preserve the flower as long as possible.
You can keep your amaryllis indefinitely, and if you can provide the right conditions for growth and dormancy, your bulb will get larger and multiply itself over the years. Large bulbs may produce as many as three flower stalks and some bulbs may bloom during the summer as well as during the winter, depending on temperature and other growing conditions.
Repeat the process
Keep it warm and water tentatively
. Keep it in cool storage
Decide when you'd like your amaryllis to bloom
Move it outdoors in spring
Increase light, water, and fertilizer
Amaryllis bulbs are forced indoors for their large, spectacular flowers. Some individuals discard the amaryllis after flowering. However, it is possible to save the amaryllis and force it to flower on an annual basis. The key to successful re-flowering is proper care.
