Amaryllis flowers are native to tropical regions and so have the ability to grow year-round in warm environments. While amaryllis flowers do not require a standard dormancy period to continue to grow and thrive, they may go through a short period where they are not growing actively. When this occurs, allow the amaryllis plant to dry out between waterings and place the plant in a dark location for approximately two months. After this period, you will be ready to break the amaryllis plant's dormancy and prepare it to bloom again.
Check the dormant amaryllis to determine whether it needs a larger planting container. If the bulb is crowded in the current container or you see new smaller bulbs attached to the main bulb, repot the bulb into a larger planting container.
Repot the amaryllis by filling the planting container approximately half-full with potting soil. Take the bulb from its current container and remove any excess soil from around the bulb. If there are new, small bulbs attached to the main bulb, remove these carefully and plant them in individual pots using the same method. Place the amaryllis bulb into the new container and cover it with soil so it is at the same depth as it was in its previous container.
Provide enough water to saturate the soil thoroughly. Do this if you repot the amaryllis plant or if you opt to leave it in its current container.
Move the amaryllis plant out of its dark location and back into a warm and bright location. A sunny windowsill with temperatures over 70 degrees Fahrenheit would be ideal.
Water the soil around the amaryllis plant to keep it evenly moist. You should soon see the plant begin to grow foliage actively again. Within four to six weeks, it should be blooming.
