Proper practices can get an amarayllis bulb to bloom on an annual basis. According to horticulturists with Iowa State University Extension and Outreach, after the amaryllis bulb has been potted up and flowered, cut off the flower stalk with a sharp knife, about two inches above the bulb without damaging the foliage. In order for the bulb to bloom again next season, it needs to replenish its depleted food reserves. Place the plant in a sunny window and water when the soil surface is nearly dry. Fertilize every two to four weeks.

The plant can be moved outdoors in late May and will need to be back inside in mid-September. Also, in order to bloom, amaryllis bulbs must be exposted to temperatures of 50 to 55 degrees Fahrenheit for at least eight weeks. An amaryllis ususally blooms six to eight weeks.
