Amaryllis Not Blooming? 5 Mistakes That Stop It Reblooming (and How to Fix Them)
Is your amaryllis not blooming, or just growing a fan of long green leaves and no flower stalk? Well, you're not alone.
Quick answer: An amaryllis not blooming usually skipped its cool rest or didn't store enough energy. Keep the leaves growing in bright light after it flowers, then rest the bulb 8 to 10 weeks at 50 to 55°F (10 to 13°C). Pot it with the top half of the bulb above the soil, and it usually blooms 6 to 8 weeks later.
My amaryllis blooms for me every year. She spends the warm months outside, and as I'm writing this at the end of October she's still out there, with no flower yet this year. That's completely normal, and it's exactly the stage where most amaryllis problems begin, so let's go through it together.
An amaryllis is not a plant that flowers whenever she likes. She works in a yearly rhythm: bloom, grow leaves, rest, wake up, bloom again. Break one step of that rhythm and you get leaves without flowers. Here are the five mistakes that break it most often, and how to fix each one.
Amaryllis Not Blooming? What Each Sign Means
| What you see | Most likely cause |
|---|---|
| Only leaves, no flower stalk | No proper cool rest, or the bulb didn't store enough energy after the last bloom. |
| Bulb getting smaller each year | Leaves were cut off too early, too little light, or no feeding while the leaves were growing. |
| Soft, mushy bulb | Too much water, especially while the bulb is resting or just potted. |
| Tall, floppy flower stalk that falls over | Not enough light while the stalk was growing. |
| No sign of life after rest | The bulb needs water and warmth to wake up, or it is still resting. |
| Blooms in spring or summer instead of winter | Normal. The timing follows when the bulb rested and woke up. |
Mistake #1: Skipping the Rest Period
This is the number one reason for an amaryllis not blooming and growing only leaves. To form a new flower stalk, the bulb needs a cool rest after a season of growing.
Toward the end of summer or early autumn, move her to a cool, dim spot and slowly stop watering. The leaves will turn yellow and then brown. Once they're dry, cut them off just above the bulb. Then let the bulb rest at about 50 to 55°F (10 to 13°C) for at least 8 to 10 weeks. A cool basement, a frost-free garage, or an unheated room works well. The cool temperature during this rest is what Iowa State University Extension names as the key to reblooming.
If you'd rather not let her go fully dormant, there's a gentler option: keep her green in a bright, cool spot at that same 50 to 55°F for those weeks, then move her somewhere warm. The cool spell is what matters most.
Want flowers for Christmas? Count back. After the rest, she usually blooms 6 to 8 weeks after you wake her up, so start the rest in late summer and wake her in late October or early November.
Mistake #2: Cutting Off the Leaves After She Blooms
When the flowers fade, it's tempting to tidy everything away. But those long green leaves are what feeds next year's flowers. All spring and summer they make energy and store it in the bulb.
So, cut only the old flower stalk, about 1 to 2 inches above the bulb, and keep every healthy leaf. Give her a sunny spot, water when the top of the soil is nearly dry, and feed her with a diluted liquid fertilizer every 2 to 4 weeks while the leaves are growing. A big, firm bulb in autumn is the best promise of flowers in winter, and a small, tired bulb is a common reason for an amaryllis not blooming the next year.
Keeping track of all this is easier when you write it down. I note when each plant flowered, when I started the rest and when I woke it up, so I know exactly what worked the next year.
Mistake #3: Not Giving Her Enough Light
An amaryllis loves light. While she's growing leaves, a sunny window or a bright spot outside in summer helps her fill the bulb with energy. In too little light, the bulb shrinks and the next flower stalk may never come.
Light matters while the flower stalk grows too. In a dim room, the stalk stretches toward the window, gets tall and weak, and can fall over under the weight of the flowers. Give the pot a quarter turn every couple of days so the stalk grows straight. Once the flowers open, a slightly cooler spot out of direct sun helps them last longer. If you're not sure your window is bright enough, my guide to light requirements for houseplants will help.
Mistake #4: Overwatering a Resting or Newly Potted Bulb
A bulb without leaves doesn't use much water. If the soil stays wet while she's resting, or right after you pot her, the bulb can turn soft and start to rot.
When you wake her up, water once thoroughly and let the excess drain away. Then wait. Check the soil every few days so it doesn't dry out completely, but don't water again until you see new growth. Once the stalk and leaves are growing, water when the top of the soil starts to feel dry.
Gently squeeze the bulb now and then. A healthy bulb feels firm, like an onion. If it feels soft or smells bad, check it straight away. My guide on how to fix root rot walks you through what to do.
Mistake #5: Planting the Bulb Too Deep or in a Pot That's Too Big
An amaryllis likes a snug pot. Choose one only about 1 to 2 inches wider than the bulb, with drainage holes, and a heavy pot helps because she gets top heavy in flower. In a big pot, the extra soil stays wet for too long.
Don't bury her. Plant the bulb so the top half sits above the soil, with the neck clearly showing. Leave about an inch between the soil and the rim of the pot so you can water easily.
Can Amaryllis Stay Outside in Autumn?
Mine is still outside as I write this, so this is a question I think about every autumn. An amaryllis is happy outside in summer, in a spot with some sun and some shade, as long as you water her in dry weather. Cooler autumn nights are actually part of how she starts slowing down for her rest.
But she is not frost hardy. Bring her in before the first frost, then give her the rest she needs. If you're moving other plants inside too, my guide on when to bring houseplants indoors and my fall checklist to prepare houseplants for winter cover the rest.
Can a Waxed Amaryllis Bloom Again?
Waxed amaryllis bulbs are everywhere around Christmas. They bloom without soil or water because the bulb already holds the energy for one flower. After that, it's very hard to bring one back. Without soil and roots, the bulb can't refill its stores and usually shrinks a lot.
If you'd like to try, carefully peel off the wax without damaging the small roots at the base, throw away the bulb if it has soft or dark sunken spots, and pot it with the top half above the soil. Then give it lots of light and regular feeding through spring and summer. It may bloom again after its next rest, but it may need a full extra season first, so treat it as a bonus rather than a promise. Iowa State University Extension gives the same honest advice.
Amaryllis or Lily? How to Tell Them Apart
The two are easy to mix up in photos, especially the orange ones. The amaryllis we grow at home (Hippeastrum) sends up a thick, hollow stalk with no leaves on it, topped with 2 to 6 huge trumpet flowers. Her leaves are long and strappy and come straight from the bulb.
A lily (Lilium) has a stem covered in narrow leaves all the way up, and its petals often curl back and can be spotted. And the plant sold as "belladonna lily" is the true Amaryllis belladonna, a different outdoor plant that flowers in late summer on bare stems.
Is Amaryllis Safe for Cats and Dogs?
No. The ASPCA lists amaryllis as toxic to cats and dogs. Chewing it can cause vomiting, drooling, diarrhea and tremors. If you have pets, keep her well out of reach, and take a look at my list of pet-friendly houseplants for safer choices.
Amaryllis keeps good company over the holidays. If you also have a Christmas cactus, a poinsettia or a cyclamen, I have guides for those too. And while you wait for her stalk to appear, you're welcome to relax with some of my calming music for plants.

Frequently Asked Questions
Why is my amaryllis only growing leaves?
Leaves without a flower stalk usually mean the bulb did not get a proper cool rest, or it did not store enough energy after its last bloom. Let the leaves grow in bright light through summer, then give the bulb 8 to 10 weeks of rest at 50 to 55°F (10 to 13°C).
How do I get my amaryllis to rebloom?
After it flowers, cut only the flower stalk and keep the leaves growing in a sunny spot with regular, diluted feeding. In late summer or early autumn, let it rest in a cool, dim place for 8 to 10 weeks, then pot it in fresh soil, water once and move it somewhere warm and bright.
How long does it take an amaryllis to bloom after waking up?
Usually 6 to 8 weeks after you water it and move it to a warm, bright spot. Bulbs grown in different regions can be a little faster or slower.
How do I get my amaryllis to bloom for Christmas?
Count back from the date you want flowers. Start the rest in late summer and wake the bulb in late October or early November, and it will usually flower 6 to 8 weeks later.
Can amaryllis stay outside in winter?
No. Amaryllis enjoys a summer outside, but it is not frost hardy. Bring it in before the first frost and give it its rest period indoors.
Should I cut the leaves off my amaryllis after it blooms?
No. Cut only the old flower stalk, about 1 to 2 inches above the bulb. The leaves refill the bulb with energy for next year, so let them grow until they yellow and dry naturally before the rest period.
Can a waxed amaryllis bloom again?
It is possible but difficult. Without soil and roots, a waxed bulb uses up its stored energy. Remove the wax carefully, pot it with the top half above the soil, and give it plenty of light and feeding. It may bloom after its next rest, or it may need an extra season.
Is amaryllis toxic to cats and dogs?
Yes. The ASPCA lists amaryllis as toxic to cats and dogs. It can cause vomiting, drooling, diarrhea and tremors, so keep it out of reach of pets.
