Amaryllis flowers typically bloom 6 to 8 weeks after they are potted, so if you want your bulb to flower for Christmas or New Year’s, plant it in early to mid-November.
Choose a pot that is about 2 inches wider than the diameter of the bulb. Amaryllis bulbs prefer to feel crowded.
You can use loose soil or decorative potting material, such as glass or stone pebbles. Whatever you choose, it should be quick draining.
Bury the bulb so that its top half remains above the surface. Place a stake in the pot at planting time. The flowers can get top heavy and staking your bulb now will protect the bulb and roots later. Water the bulb well and put the pot in a cool place. Keep it just barely moist until the amaryllis bulb begins to show growth. Place your plant in bright, indirect light and keep the soil moist, but not wet.
A thick flower stalk should shoot up within a few weeks. The flat leaves will follow as the flower stalk matures.
