Here's some tips on keeping it healthy and happy.
Amaryllis
The Amaryllis is a tropical, originating in South America, and is grown for its large, 8 to 10 inch blooms. It comes in shades of red, pink, orange, coral, white and bicolor.
Plant the amaryllis bulb in a pot with adequate drainage, just barely larger than the bulb. Amaryllis like to be pot-bound. Use sterile potting soil, adding about an inch to the bottom of the pot. Place the bulb in the pot making sure to spread the roots carefully. Add more soil, leaving about 2/3 of the bulb above the soil-level. Water thoroughly. When it begins to grow, move the amaryllis to a sunny window. Water whenever the soil feels dry to the touch. Fertilize monthly.
After the plant has finished blooming, cut back the flower stalk but not the leaves. Continue to grow the plant as you would any other houseplant, watering and fertilizing at regular intervals.
In the spring, place the amaryllis plant in a window where is can get bright sun or move it outside to a sunny location.
In September, bring the plant indoors. Place in a cool area (preferably about 55 degrees) and do not water for 6 to 8 weeks. In November, remove all of the old foliage and water thoroughly. Place in a sunny location. When the plant starts growing, resume fertilizing. Water sparingly at first, increasing the amount of water as the plant grows in size. New blooms should appear in 3 to 8 weeks.
