Make sure that you plant the bulbs in a pot that is about 5 to 7 inches wide. An Amaryllis Lily will bloom when it feels crowded! Also, when planting the bulb, plant it partially with the top part of the bulb sticking out. Water your Amaryllis Lily well but don’t make the mud soaking wet. Bright, indirect sun will benefit the plant. You should cut the stem after the flower fades.
