Yes, amaryllis can rebloom year after year, but there are steps you need to follow to get them to flower again reliably.
It takes anywhere from 10-14 weeks for an amaryllis to bloom again once it enters dormancy.
The process to get them to rebloom starts as soon as the flowers fade. Follow these steps for blooms every year…
Once the flowers fade and die back, use precision pruners to cut off the stem all the way down to the base.
Place your amaryllis plant in a sunny window to give it as much light as you can, or use a grow light if your home is dark.
Move your amaryllis outside for summer and feed it regularly. I recommend using a flower fertilizer, compost tea, or fish emulsion.
When it’s time to trigger dormancy (10-14 weeks before you want it to rebloom), stop fertilizing, and bring your plant back inside.
Put it in a cool, dark location, like an unheated basement or garage, where the temperature stays above freezing, 45-55°F is ideal.
Keep your amaryllis in the dark for 6-8 weeks. Allow the soil and the bulb to dry out completely, and don't water it at all.
If you stored your bulbs bare-root, pot them with fresh soil. Then, give them a deep drink, allowing the excess to drain off completely. Move them to a warm, sunny window.
Some bulbs will wake up within days of moving them to a sunny spot, others could take 4-6 weeks. Enjoy your blooming amaryllis through the holiday season!
