Growing a Christmas Cactus: How to Get a Flood of Blooms for the Holidays?
The Christmas cactus (Schlumbergera) is, right after the poinsettia, the second most popular plant of the Czech holiday season. Its exotic blooms in shades of pink, red, purple, or white can brighten any interior right when it's darkest outside.
Unlike a classic cactus, it doesn't come from the desert but from Brazilian rainforests. That means it needs slightly different care. Once you know how, it will reward you with blooms every year.

A Tip From Florist Monika (Quality and Transport)
"The biggest enemy of a Christmas cactus is cold during transport. It's a tropical plant! If you buy one at a supermarket and carry it even just 5 minutes through freezing cold to your car unprotected, it'll go into shock and drop all its buds once you get home. That's why our Christmas cacti travel by courier in heated vehicles, carefully wrapped, all the way to your door."
5 Rules for Successful Growing
To keep your Schlumbergera bringing you joy for years (it's a long-lived plant), follow these principles:
1. Light and Placement (Watch Out for Sunburn)
As a rainforest plant, it prefers bright, indirect light.
-
Ideal: An east- or north-facing window.
-
Watch out: Direct midday sun (especially in summer) would scorch its segmented leaf-pads, turning them red.
2. Temperature and Drafts
The ideal temperature for blooming is 15–20°C.
-
The cactus can't stand drafts (watch out for airing out the room in winter!) or radiant heat straight from a radiator. If it sits right above a hot heater, the buds will dry out and drop.
3. Watering (It's Not a Desert Cactus!)
Water it regularly, but with a light hand. The substrate should be slightly moist, but never soaked.
-
Rule of thumb: Let the top layer of soil dry out a little between waterings. If the roots sit in water, they'll rot.
4. Air Humidity
It loves humidity. In dry apartment air during winter, it benefits from misting the leaves (try not to spray directly onto open flowers) or placing the pot on a saucer of moist pebbles (expanded clay).
5. The Golden Rule: DON'T MOVE IT!
This is the most important piece of advice. Once the cactus sets buds, you must not change its location, or even turn it around.
-
The flowers orient themselves toward the light. If you turn the plant, it will try to reorient its flowers, which exhausts it so much that it drops the buds in shock.
The Secret: What to Do So It Blooms Again Next Year?
Many people complain that after Christmas their cactus never bloomed again. That's because it never had a rest period. For a Schlumbergera to set buds, it needs, starting in autumn (roughly from October):
-
Cool temperatures: Around 12–15°C.
-
Darkness (short days): It needs at least 12 hours of complete darkness a day.
-
Dryness: Cut watering to a minimum. Once small buds appear, you can gradually increase both temperature and watering, and look forward to a bloom by Christmas.
This regime of darkness and cold should last roughly 6 to 8 weeks, ideally from October to the end of November.
Frequently asked questions about the Christmas cactus
How do I get a Christmas cactus to bloom for Christmas?
It needs a rest period: cool temperatures around 12–15 °C, at least 12 hours of complete darkness a day and minimal watering. The regime of darkness and cold should last roughly 6 to 8 weeks, ideally from October to the end of November.
Why does a Christmas cactus drop its buds?
Most often because the plant was moved or turned after setting buds, because of a draft, radiant heat from a radiator or a chill on the way home.
How often should I water a Christmas cactus?
With care. The substrate should be slightly moist, never soggy, and the top layer may dry out a little between waterings. During the dark and cool period, keep watering to a minimum.
Where should I put a Christmas cactus?
In a bright place with indirect light, ideally by an east or north window. Protect it from midday sun, drafts and heat from a radiator. For flowering it likes 15–20 °C.
Why did my Christmas cactus not bloom again after Christmas?
It probably did not have a rest period. To set buds, it needs cool temperatures, darkness and little water in autumn for roughly 6 to 8 weeks.
