One of the most frequent questions we hear this time of year is: what do I do with my amaryllis bulb when it’s finished blooming and how can I get it to re-bloom next year?
The answer: It’s not that hard, and given how gorgeous these bulbs can be as they grow larger and larger year by year, it’s certainly worth the effort.
Once the flower is finished, cut off the stem just above the bulb nose. Place the amaryllis in bright light on a sunny windowsill or under plant lights. Feed and water regularly. Apply a standard water-soluble houseplant fertilizer at half the recommended strength every two weeks.
Keep bulb in a pot sized “just right”. As the bulb grows and the pot fills with roots, move it up to a bigger pot that’s just slightly larger than the bulb.
In summer, move the pot outdoors into a sunny spot and treat it like a container plant. Continue fertilizing until the middle of August. Don’t allow the soil to dry out, but avoid keeping it soggy.
In fall, before there’s a chance of frost, bring the plant inside and place in a sunny window or under plant lights. The leaves may yellow and die off by late December. During this time, keep the plant moist, not wet; but most importantly, don’t let the pot dry out. The buds for the new flowers should appear in January or February, but sometimes they bloom as late as March.
After flowering, resume feeding and keep the pot in a sunny window or under plant lights until it can go outdoors again. Big vigorously growing bulbs will produce offsets – little baby bulbs – which you can pot up to grow to flowering size in a couple of seasons.
