Amaryllis plants can rebloom year after year, but there are a few steps you’ll need to take to get them to flower again reliably.
You can easily trigger it by controlling the light, water, and temperature. It’s also important to get the timing right to ensure the biggest and most robust display for the holidays.
In this post I’m going to show you exactly how to make your amaryllis bloom again, with detailed step-by-step instructions, and I’ll also tell you when you need to start the process.
What Triggers Amaryllis To Rebloom?
There are 3 main environmental changes that trigger an amaryllis to bloom: drought, darkness, and cool temperatures.
These three things will force the bulb to go dormant, or rest. They need 6-8 weeks of rest so they can build up enough energy to flower.

When Will Mine Flower Again?
If you follow the correct steps, your amaryllis will bloom about 4-6 weeks after you bring it out of the dark, or once it breaks dormancy.
It’s easy to control the timing for Christmas. But if you let it happen naturally, they can flower anywhere from mid-winter through spring, depending on the environment.
How Do I Get My Amaryllis To Bloom Again?
To get your amaryllis to rebloom, you need to control the amount of water and light you give it, as well as the temperature.
If you’re trying to time it for Christmas, you should start the process sometime between September 17 and October 15. Here are the 4 main steps to take.
1. Stop Watering & Fertilizing
You should stop watering and feeding your plant in the fall about 10-14 weeks before you want it to flower again.
This is the first trigger to the bulb that it’s time to rest. At this time, allow the soil to dry out completely, and don’t water it at all.
2. Put It In The Dark
The bulb needs complete darkness for 6-8 weeks. So move it inside to a dark and dry location, like a closet, windowless garage, basement, or a storage area.
You can leave the bulb right in the pot, or dig it up and store it bare-root. The leaves will eventually die back on their own, or you could cut them off if you prefer.
3. Keep It Cool
Though it’s not as important to get the temperature exactly right for reblooming, it’s best to keep your amaryllis bulb cool so it doesn’t break dormancy early.
So try to find a spot where the temperature stays between 45-60°F, but make sure it never drops below freezing.

4. Wake It Up
After 4-6 weeks, bring your amaryllis out of the dark and give it a deep drink to moisten the soil. If yours is bare-root, pot it up using a fresh growing mix.
Then move it to a warm area where it will get lots of bright light. The best spot is a sunny location, like a south-facing window.
How Long Does It Take Amaryllis To Bloom Again?
It takes anywhere from 10 to 14 weeks for an amaryllis to rebloom once it enters dormancy.
After you bring it out of the dark, it could start to sprout right away, or it can take a few weeks, depending on the environment.
But it will usually take 6 to 8 weeks for your plant to come into full bloom after its rest period.
Why Won’t My Amaryllis rebloom?
Your amaryllis won’t rebloom if it hasn’t regenerated enough energy, or if it doesn’t get a proper rest period.
They need 4-6 weeks of dormancy to flower again, which doesn’t always happen naturally, so you’ll need to force it.
But if you follow all the steps to give it a rest, and it still won’t bloom, then make sure you’re giving it the right care during the active growth season.
To build up the energy, they need lots of sunlight and fertilizer in the spring and summer months. The easiest way to provide that is to put your plant outside in a full sun location during the summer, and feed it monthly with a flowering fertilizer or compost tea.

Why Is My Amaryllis Only Growing Leaves?
Don’t panic if your amaryllis only has leaves at first. Sometimes the foliage will start to grow before the flower stalk, and that’s perfectly normal.
This doesn’t mean it won’t bloom again, just be patient and give it more time. You can tell the difference right away because the leaves are flat and thin, and the bud is thick and fat.
What To Do Once It Starts Blooming
For the biggest and best display, it’s very important to give your amaryllis the proper care when it starts to rebloom. Otherwise the spikes can get tall and leggy and fall over, or the flowers may not be very large. Here’s how to treat your plant once it starts sprouting.
- Increase watering – Keep the soil evenly moist, but do not overwater. Let the top 1” dry between drinks. Use a moisture gauge probe to get it right.
- Give it plenty of light – Once they start budding, the flower stems grow very quickly. So give it as much sunlight as possible to prevent legginess. If your home is dark, add a grow light.
- Keep it warm – If the room is cold it will take much longer for the flower buds to open. For the quickest results, keep the temperature between 65-80°F. You can place the potted bulb on a heat mat to speed things up.

Typically each bulb will only bloom one time per year, but some will flower twice. They will rebloom again reliably every year for decades when you take the proper steps.
Yes, a waxed amaryllis can rebloom. Simply remove the wax and plant your bulb into soil after it’s done flowering so it can regenerate enough energy for next year.
To get timing right for Christmas, you need to start the rest period sometime in late-September to mid-October. Then bring them out of storage in mid to late November, or 6-8 weeks after you put them in the dark.

How To Rebloom Amaryllis Bulbs
It's easy to trigger your amaryllis to bloom every year. Follow these simple instructions for the biggest and most beautiful flowers.
Materials
- Amaryllis plant
- Potting soil (optional)
Instructions
- Stop watering and fertilizing - Beginning somewhere between 10-14 weeks before you want your plant to rebloom, stop fertilizing and watering it.
- Force dormancy - Put it in a cool, dark location, like an unheated basement or garage, where the temperature will stay between 45-60°F. You can leave it in the pot or store it bare-root.
- Wait for 6-8 weeks - 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. The leaves will die back, so you can remove them as they dry up or use sharp pruners to cut them off while they’re still green.
- Wake up the bulb - If you stored your bulb bare-root, plant it in a container with drainage holes using fresh potting soil. Give it a deep drink, allowing the excess to drain off completely. Then move it to a warm, sunny window or use a grow light.
- Watch for new growth - Some amaryllis bulbs will start blooming within a few days, while others could take 4-6 weeks - so be patient. Try placing the pot on a heat mat to help break dormancy faster.
Notes
- Amaryllis flower bulbs must rest for 6-8 weeks, and it can take another 4-6 weeks for them to rebloom. So for a Christmas display, put them into storage sometime in mid-September to mid-October.
- Don’t worry if yours starts getting leaves before flowers, sometimes that happens. It's normal, so just be patient and give it more time.
- Amaryllis bulbs need to be fully mature to bloom. So, smaller ones may not flower, even if you follow all of these steps perfectly. It could take several years before they’re large enough.

What if you live in FL? I have many bulbs in the ground all year, but they have not rebloomed.
Amy Andrychowicz says
If your amaryllis bulbs don’t go dormant on their own in your garden, then you’ll probably need to dig them up and force dormancy to get them to bloom. Here’s more information about amaryllis dormancy.

I bought an amaryllis bulb at the Keukenhof Gardens about 12 years ago. It bloomed once after that and never again…just shoots up leaves. I’ve done the steps you recommend but nothing happens. I recently bought 2 bulbs after Christmas for a couple of dollars and they just finished blooming beautifully.
Amy Andrychowicz says
Make sure you give your amaryllis full sun and lots of fertilizer during the summer months, and that the bulb gets a long enough period of dormancy. Here are more tips for how to properly care for an amaryllis plant for the best results.
Marie Jorland says
My plant is root bound. When I brought it out of dormancy, I replanted it in a little bit larger pot and watered it. Should I have loosened the roots and should I fertilize it at this point
Amy Andrychowicz says
It’s always a good idea to break up the roots on an extremely pot-bound plant. But at this point, I would leave your amaryllis in the pot and wait for it to rebloom. Next time you repot it you can break up the roots. And no, don’t fertilize it at this point. Start feeding it in the spring and all through summer. Here’s my complete care guide for more info.
