Florist cyclamen brightens a winter windowsill with swept-back blooms in red, pink, white and purple, set over silver-marked, heart-shaped leaves. Many people treat it as a short-lived gift plant.
If you learn how to care for cyclamen, though, it can bloom for months and come back for another season.
The basics are simple: keep it cool, give it bright indirect light, water it from below and let it rest in summer.
In this guide I’ll cover choosing a plant, watering, feeding, deadheading and dormancy, plus the problems to watch for and why pet owners need to be careful.
Choosing a Healthy Florist Cyclamen
Pick a plant with firm, unblemished leaves and plenty of unopened buds tucked under the foliage. A healthy start is the easiest way to get a long bloom season.
Florist cyclamen (Cyclamen persicum) grows from a flattened, round tuber that sits at the soil surface.
It blooms from fall through spring, often for 2 to 3 months or more, so a plant with lots of buds still has most of its show ahead of it.
What to Look for at the Store
Lift the leaves gently and look underneath. You want to see many tight buds on short stems below the open flowers. A plant with only open blooms is already past its peak.
Check these points before you buy:
- Leaves are firm, upright and evenly colored, with no yellowing
- No gray fuzz on leaves, stems or the tuber
- Flower stems stand up straight rather than flopping over
- The tuber feels firm, not soft or mushy, where it meets the soil
- No distorted, curled or speckled new leaves, which can point to mites
Avoid Plants Kept in Warm Spots
Cyclamen sold near store entrances or by heaters may already be stressed. Heat shortens bloom and brings on yellow leaves. If you have a choice, buy from a cool display and take it straight home.
On cold days, wrap the plant loosely for the trip. A short blast of freezing air can damage the flowers and leaves.
Supplies to Have on Hand
You don’t need much to keep a cyclamen happy. My advice is to have two basic products ready before the plant needs them.
- Potting mix: A well-drained potting mix for when you repot later in the year
- Liquid fertilizer: A balanced liquid fertilizer you can dilute to half strength while the plant blooms
A saucer or shallow tray for bottom watering is also handy. A plain kitchen bowl works fine.
| Feature | Healthy Plant | Plant to Skip |
|---|---|---|
| Buds | Many unopened buds under leaves | Mostly open or fading flowers |
| Leaves | Firm, green, patterned | Yellow, limp or spotted |
| Tuber | Firm and dry on top | Soft, dark or moldy |
| New growth | Flat and even | Curled or distorted |
The Best Light for Indoor Cyclamen
Cyclamen wants bright, indirect light, such as you’d find in an east-facing window. Avoid hot direct sun, which heats the plant and cuts the bloom season short.
Good light keeps leaves compact and flowers coming. Too little light makes stems stretch and lean, while too much sun scorches leaves and warms the soil.
East Windows and Other Good Spots
An east-facing window gives gentle morning sun and bright light the rest of the day. That’s my top pick for cyclamen.
A north window can work if it’s bright and unobstructed. South or west windows are fine in deep winter if you set the plant a few feet back or behind a sheer curtain.
Signs of Too Much or Too Little Light
Cyclamen tells you quickly if the light is wrong. Learn these signals so you can move it before damage builds.
- Too little light: Long, weak stems, leaves leaning toward the window, fewer buds
- Too much sun: Pale or bleached patches, crispy leaf edges, flowers fading fast
- Too much heat from the window: Yellowing leaves and drooping, even with damp soil
Rotating and Seasonal Adjustments
Turn the pot a quarter turn every week. This keeps the plant growing evenly instead of reaching to one side.
As spring days get longer and stronger, the sun through a window can heat up the plant. Pull it back from the glass in March and April to keep it cool.
Keeping Cyclamen Cool: Ideal Temperatures
Cyclamen does best at 50 to 65°F during the day and 40 to 50°F at night. Cool rooms are the single biggest secret to a long bloom season.
This is where most indoor cyclamen go wrong. Our homes are built for people, and a typical 70°F living room is too warm for this plant.
Why Heat Shortens Bloom
Cyclamen is native to cool, mild-winter regions where it grows and flowers during the cooler months. Warmth signals the end of its season.
Temperatures above 70°F shorten bloom and trigger yellowing leaves. They can also push the plant into early dormancy, long before spring ends.
Finding the Coolest Spot in Your Home
Look for rooms you don’t heat much. A cool bedroom, an enclosed porch that stays above freezing, or a bright entryway often works well.
Window sills are often cooler than the rest of the room in winter. Just make sure leaves don’t touch freezing glass on very cold nights.
| Condition | Temperature | Effect on Cyclamen |
|---|---|---|
| Ideal day | 50 to 65°F | Steady blooms, healthy leaves |
| Ideal night | 40 to 50°F | Longer bloom life |
| Too warm | Above 70°F | Yellow leaves, short bloom, early dormancy |
| Near freezing | Below 35°F | Risk of cold damage |
Keep It Away From Heat Sources
Keep plants away from heat vents, radiators and fireplaces. Dry, warm air blowing on a cyclamen wilts flowers in days.
How to Water Cyclamen From the Bottom
Water when the top 1 inch of soil is dry by setting the pot in water for 15 to 20 minutes, then draining it fully. Bottom watering keeps water off the tuber, which is where rot starts.
Step-by-Step Bottom Watering
Bottom watering is easy once you’ve done it a couple of times. Here’s how I recommend doing it:
- Push a finger into the soil. If the top inch feels dry, it’s time to water.
- Fill a bowl, sink or tray with a few inches of room-temperature water.
- Set the pot in the water so the drainage holes sit below the surface.
- Leave it for 15 to 20 minutes while the soil soaks up water from below.
- Lift the pot out and let it drain completely before setting it back in its saucer.
The soil surface should look darker and feel damp when it’s done. If it still feels dry on top, give it a few more minutes.
Keep Water Off the Tuber Crown
The top of the tuber, where leaf and flower stems emerge, is called the crown. Water sitting there invites rot, and a rotting crown is hard to save.
If you must water from the top, pour gently around the edge of the pot. Tuck the leaves aside so the water lands on soil, not on the tuber.
How to Tell If You’re Over or Underwatering
Both mistakes cause drooping, so check the soil before reacting. A wilted cyclamen in dry soil perks up within hours of a good soak.
- Underwatered: Leaves and flowers droop, soil is dry and the pot feels light
- Overwatered: Stems collapse, leaves yellow, soil stays wet and the tuber may feel soft
- Just right: Firm, upright stems and soil that’s lightly moist below the surface

Humidity, Soil and Feeding While in Bloom
Cyclamen likes about 50 percent humidity, a well-drained potting mix and light feeding every 2 to 4 weeks while it blooms. These three things keep flowers coming steadily.
Good basic care for cyclamen in bloom is mostly about balance. You want moist air without wet leaves, and nutrients without overfeeding.
Raising Humidity the Safe Way
Winter heating often drops indoor humidity well below 50 percent. Dry air makes flowers fade faster and can invite spider mites.
A pebble tray works well. Fill a shallow tray with pebbles, add water to just below the top of the stones, and set the pot on top so the pot never sits in water.
Grouping plants together also helps a little. I’d skip misting cyclamen, because water on leaves and the crown can lead to gray mold and rot.
Choosing the Right Soil and Pot
Use a well-drained potting mix and a pot with drainage holes. Cyclamen roots need air, and heavy, soggy soil leads straight to crown rot.
A standard indoor mix with some added perlite drains well. For more detail on mixes, see my guide to the best soil for indoor plants.
Skip decorative pots without holes unless you slip the plant’s nursery pot inside and empty any water that collects.
Feeding Cyclamen During Bloom
Feed every 2 to 4 weeks with a half-strength liquid fertilizer while the plant is blooming. Mix it into the water you use for bottom watering.
Stop feeding once leaves begin to yellow in late spring. A resting tuber doesn’t need nutrients, and extra fertilizer can build up in the soil. My guide on how often to fertilize indoor plan
