How to Make Amaryllis Bloom


Temperature and light are the keys to getting amaryllis plants to bloom year after year. Though they are often sold with striking blossoms during the holiday season, the natural flowering season for amaryllis plants is the spring. Little has to be done to get them to flower during March, April and May. But if you want your plants to provide holiday splendor, you have to start grooming them for next year just after they finish blooming this year.

Step 1

Keep your blooming amaryllis in a location with a temperature of about 60 degrees F in an area out of direct sunlight. Keep the soil slightly moist and when you do water it, don't get the tip of the bulb wet.

Step 2

Cut off flower stalks near the base of the plant, near the bulb, when your amaryllis is done blooming. Do not cut the foliage, just the flower stems.

Step 3

Move your amaryllis to a sunny location, such as a south-facing window, greenhouse or sun room. Keep the soil moist at all times and fertilize it monthly with a liquid fertilizer designed for bulbs. Follow manufacturer dosing and application methods.

Step 4

Move your amaryllis outdoors when the danger of frost has passed. It should be in full sun, and the soil should remain moist at all times. Water your plant every day if necessary. Fertilize every two weeks with a slow-releasing fertilizer designed for bulbs and follow manufacturer dosing and application methods.

Step 5

Move the plant to cool storage about four months before you want it to bloom. An area that is about 55 degrees F is ideal. This process is called forcing.

Step 6

Keep the amaryllis dry during storage. It will lose all its leaves. Check on your plant once a week to check for a new tip emerging from the bulb. This can take eight to 10 weeks.

Step 7

Repot your amaryllis in high-quality, all-purpose potting soil once the stem has emerged. The top third of the bulb should not be covered with dirt. Water slowly until the water seeps out of the bottom of the pot. If smaller bulbs are growing on the main bulb, remove them with your hand and repot them. They may bloom in a couple of years.

Step 8

Move the pot to a warm and sunny location around 70 to 80 degrees F. Keep the soil moist and remember don't get the tip of the bulb wet. Your amaryllis will continue to grow and will soon begin to bloom.
