You’ve seen them in every grocery store the moment the temperature drops. Those shock-pink or snowy white petals that look like they’re trying to fly away from the pot. It's the florist’s cyclamen, or Cyclamen persicum. Most people buy one, enjoy it for three weeks, and then toss it when the leaves turn yellow and the stems go mushy. It’s a tragedy, honestly. Care of cyclamen plants indoors shouldn't be a death sentence for the tuber, but we treat these plants like disposable bouquets rather than the long-lived perennials they actually are.
The problem is that cyclamens are basically the "anti-houseplant." Most of what we’ve learned about keeping monsteras or pothos alive will actively kill a cyclamen. They don't want your cozy 72-degree living room. They hate your misting bottle. If you treat them like a tropical jungle inhabitant, they’ll rot before the first snowfall hits.
The Cold Hard Truth About Temperature
If you're comfortable in a t-shirt, your cyclamen is probably miserable. These plants are native to the Mediterranean and parts of North Africa, but they specifically thrive in the cool, rainy winters of those regions. They are built for the chill. To succeed with care of cyclamen plants indoors, you have to find the draftiest, unheated room in your house.
Think 50°F to 60°F at night. Maybe 65°F during the day.
If you put your pot on top of a radiator or near a heating vent, it’s game over. The plant will think it’s summer. In the world of a cyclamen, summer means "time to die back and hide underground." The leaves will yellow, the flowers will drop, and you'll think you killed it. You didn't—you just accidentally sent it into a premature coma. Professional growers, like those at the University of Vermont Extension, emphasize that heat is the number one killer of indoor cyclamens. Keep them cool. Keep them shivering, almost.
Water: The Fine Line Between Life and Rot
Watering a cyclamen is a bit of a high-wire act. You can't just pour water into the center of the plant. If you get the "crown"—that chunky tuber sitting at the soil line—wet, it will develop a fungal rot faster than you can say "botrytis."

I’ve found the best way is the bottom-soak method. Basically, you set the pot in a saucer of water for about 15 minutes. Let it drink from the bottom up. Once the top of the soil feels slightly damp, take it out. Never let it sit in a puddle for hours. They hate wet feet. But they also hate being bone dry. It’s a lot, I know. You're looking for that "wrung-out sponge" consistency.
Why Drainage is Non-Negotiable
Most decorative pots don't have holes. That’s a trap. If your cyclamen came in a plastic nursery pot tucked inside a pretty ceramic one, take the plastic one out to water it. Let it drain completely in the sink before putting it back. If water pools at the bottom of that ceramic decorative pot, the roots will suffocate. Oxygen is just as important as water for these guys.
Light Needs and the "Winter Sun" Paradox
We often think "indirect light" means a dark corner. For a cyclamen, it doesn't. During their blooming phase in the winter, they need high-quality light. A north-facing window might be too dark. An east or west window is usually the "Goldilocks" zone.
But here’s the kicker: the sun shouldn't be "hot" on the leaves. If you feel the sun warming your skin through the glass, it's too much for the cyclamen. It’s a delicate balance. They want the brightness of a winter day without the heat of a greenhouse. If the stems start getting long, leggy, and floppy, it's begging for more light. If the leaves look scorched or bleached, back it off.
Deadheading and Maintenance (The "Tug" Technique)

When a flower fades or a leaf turns yellow, don't just snip the top off. If you leave a stump of a stem, that stump will rot and potentially infect the tuber. Instead, reach down deep into the base of the plant, grab the stem firmly, and give it a sharp, quick tug. It should "pop" right off the tuber. This clean break allows the plant to heal quickly. It's oddly satisfying once you get the hang of it.
Feeding for Longevity
You don't need to fertilize a cyclamen while it's in full, glorious bloom. It's already using the energy it stored up in the tuber from the previous year. Wait until the flowers start to thin out, then use a balanced, water-soluble fertilizer at half strength every two weeks. Avoid high-nitrogen blends. You want flowers, not just a bush of leaves. Nitrogen gives you the latter; phosphorus and potassium give you the former.
The Dormancy Phase: Don't Throw It Away!
This is where everyone fails at care of cyclamen plants indoors. Usually around April or May, the plant starts looking like it’s dying. It isn't. It’s going to sleep. In the wild, the Mediterranean summer is too hot and dry for the delicate leaves, so the plant retreats into its tuber.
When the leaves start to yellow, stop watering. Completely.
Let the foliage die back naturally. Once it's all shriveled, pull it off and put the pot in a cool, dark place. The basement is perfect. A dark closet works too. Leave it there for two or three months. Don't touch it. No water. No light. No nothing.

Around mid-summer or early fall, you might see a tiny nub of green peeking out from the tuber. That’s your signal. Bring it back into the light, give it a good soak, and start the cycle all over again. Most people find this too much work and buy a new one for $10, but there's a real pride in getting a cyclamen to rebloom for a second or third year.
Common Pests and Problems
Cyclamen mites are the stuff of nightmares. They are microscopic, so you won't see them, but you’ll see the damage. The leaves will look stunted, twisted, and "fuzzy" or gray. Honestly? If you get a bad infestation of mites, it’s often better to discard the plant. They are incredibly difficult to get rid of without heavy-duty chemicals that you probably don't want in your kitchen.
Aphids and fungus gnats are more common and easier to handle. Neem oil or insecticidal soap works, but again, be careful not to soak the crown of the plant. If you see tiny little flies buzzing around, you're likely overwatering. The soil is staying too wet, creating a playground for gnat larvae.
The Mystery of the Drooping Stem
If your plant is suddenly drooping but the soil is wet, it’s not thirsty. It’s rotting. This is the "silent killer" of indoor cyclamens. Check the base of the stems. If they feel mushy or slimy, you’ve likely overwatered or kept the room too warm. At this point, it’s hard to save, but you can try letting it dry out completely and hope the tuber hasn't turned to mush yet.
Selecting the Right Variety
Not all cyclamens are created equal. The ones you find at the florist are "Florist’s Cyclamen." They have large, showy flowers. However, there are also "Miniature" varieties that are often a bit hardier and sometimes even have a faint, sweet scent that the big ones lack. If you have a choice, the miniatures often adapt slightly better to indoor environments because they handle temperature fluctuations with a bit more grace.
Essential Action Steps for Your Cyclamen
To ensure your plant thrives rather than just survives, follow these immediate steps:
- Relocate immediately: Move the pot to the coolest spot in your home—ideally a window that stays between 50°F and 60°F.
- The "Finger Test": Only water when the top inch of soil feels dry to the touch, and always water from the bottom.
- Clean the Crown: Ensure no dead leaves or spent flower stems are sitting on top of the tuber; "pop" them off at the base to prevent fungal growth.
- Monitor Light: If the plant leans heavily toward the window, rotate it a quarter turn every few days to keep growth even.
- Plan for the Nap: Mark your calendar for April to begin reducing water and preparing the plant for its mandatory summer dormancy.
Properly managed, a cyclamen isn't just a winter decoration. It’s a legacy plant that can return year after year, providing color when the rest of the world is gray and frozen.
