When buds form, resume regular watering and feeding again. If the plant does not stay moist, there may be bud drop. The Christmas cactus is available in pink, white, red and violet. 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. When it begins to grow, move the amaryllis to a sunny window. Water whenever the soil feels dry to the touch. After the plant has finished blooming, cut back the flower stalk but not the leaves.
