Pot amaryllis in a container that is 6 to 8 inches in diameter and use loose, well-draining soil, and place the plant in an area with bright, indirect sunlight. Provide the plant with water when the soil is dry, and add a liquid fertilizer on a regular basis. After flowering, cut the flower stalk off 2 to 3 inches above the bulb, and allow the bulb to become dormant for at least eight weeks to encourage new blooms.Continue Reading
To pot an amaryllis bulb, place the bulb with the pointed end up in a heavy container, and add enough potting soil to cover two-thirds of the bulb. Lightly water the bulb until the new growth is 2 inches tall, and cut the flower stalk off 2 to 3 inches above the bulb after it turns yellow. Water the plant thoroughly when the top 2 inches of soil is dry.
Stop watering the plant, and allow the soil to dry out to force the plant into a dormant stage. Place the dormant bulb in a cool, dry place.
To promote flowering after dormancy, begin watering the plant lightly until new growth appears. When new growth appears, water the plant normally and use a recommended fertilizer. Repot the plant every three to four years directly after a dormant period.Learn more about Outdoor Plants & Flowers
