Amaryllis bulbs are a foolproof way to produce spectacular indoor blooms during winter. Each bulb produces three to four large flowers on a single stem. By starting an amaryllis bulb every two to three weeks from early fall through the end of the year, you will have a succession of blooms from mid-December through March. Amaryllis flowers come in classic bright red, but there are also white, pink and striped varieties.
Choose the proper pot. An amaryllis pot is a terra-cotta pot that is much deeper than a standard clay pot. This is to help balance the weight of the plant so the pot doesn't tip over. You can also use a standard clay pot, but make sure to put extra rocks in the bottom.
Prepare the pot. Put a piece of broken clay pot or a rock over the drainage hole in the bottom. Fill the pot one-third full with indoor potting soil.
Plant amaryllis bulbs one to a pot. Set the bulb on the soil on its flat side and with the pointed side up. Add more potting soil, tapping the bottom of the pot on the table to settle the soil. Continue to add more soil until three-quarters of the bulb is buried.
Water the potted amaryllis well. The water should drain out of the bottom of the pot.
Place the potted amaryllis bulb in a bright room, but not in a south-facing window. Water the plant when the soil feels dry to the touch. Don't overwater but don't allow the soil to dry out. Amaryllis bulbs bloom in 10 to 12 weeks after potting.
