With its lovely pink, red or white blooms that appear late Fall or early Winter, the gorgeous Christmas cactus (Schlumbergera) might tempt you to brighten up your home a little this holiday season. Luckily, Christmas cacti aren’t difficult to care for and with a little effort you can enjoy yours (and its flowers!) for years to come.

Christmas cactus care
Unlike many of the other cactus species we keep as houseplants, Christmas cacti are not naturally found in dry desert habitats. They are forest cacti originating from Brazil, where they grow on trees and rocks instead of in the ground.
Their humid jungle habitat gives us some good care indications: these cacti need more water and humidity than their desert cousins but no direct sunlight, as this is naturally blocked out by taller trees.
Christmas cactus light, location & temperature
In order to succesfully grow Christmas cacti, it’s a good idea to keep their natural habitat in mind.
- This means that bright indirect light is preferred and direct sunlight is a bad idea for the most part (though some early morning, late afternoon or Winter sun shouldn’t be too much of an issue).
- Like other succulents, a Christmas cactus exposed to too much light will turn a pinkish red, which is an indication you might want to move it to a more shaded spot.
- Christmas cactus bloom is triggered by changes in light and temperature. Once the days get shorter buds will start to form, so make sure the plant is not exposed to (artificial) light in the evenings/nights during the blooming period.
- Room temperature is just fine for Christmas cacti, though they can also withstand much lower and higher temps; just try to avoid anything below 50 °F/10 °C.
- Slightly lower temperatures are one factor that triggers bud formation in Christmas cacti, although it doesn’t seem to be an absolute must for flowers.
- Keep in mind that these cacti don’t like to be moved around during the blooming period. They might drop their buds or flowers when disturbed too much!
Christmas cactus soil & planting
Christmas cacti are quite undemanding when it comes to soil, though the ideal mixture is said to be a bit acidic (many use peat moss for this, though there is still a lot of discussion about its sustainability) and holds water relatively well while some added perlite helps ensure proper drainage.
A relatively wide planter with a drainage hole is preferable. Christmas cacti don’t have to be repotted often and should still flower just fine even when when root bound as long as the soil is refreshed every few years. If you do choose to repot, go one size up at a time.
Watering Christmas cactus
Although they are succulents that can store water in their leaves for dry periods, Christmas cacti don’t respond well to being left to dry too often or too long, nor do they appreciate very dry air.
Because they naturally grow in relatively moist areas they require a different watering schedule than their desert cousins: they like to be kept moist (though never wet) from the start of the growing season in early Spring until the end of the blooming period when all the flowers have dropped. As with most other houseplants, when no growing or blooming is going on less moisture is needed, so reduce waterings and let the soil dry out a bit more during this period.
Although natural Christmas cactus habitat is quite humid, normal home humidity levels should be fine for this plant unless the air is very dry. A humidity tray or some extra misting are probably appreciated, though not necessary in most cases.
Christmas cactus fertilizer
Which type of fertilizer works best for Christmas cacti is not entirely clear. Some sources recommend using a balanced, regular houseplant fertilizer while others mention a fertilizer with higher potassium content works better.
Regardless of what you end up going for, you can fertilize with a diluted solution around once a month during the growing season. Stop fertilizing between early Fall and early Spring.
Christmas cactus vs Thanksgiving cactus
There is quite a bit of confusion out there about Christmas cactus taxonomy. The “true” Christmas cactus is Schlumbergera x buckleyi, with slightly rounded leaf points. Schlumbergera truncata has pointier leaves and blooms a little earlier; it is sold as both “Christmas cactus” and “Thanksgiving cactus”. If you buy a plant labeled as Christmas cactus, it is usually Schlumbergera truncata.
If youre unsure whether you own a “true” or “false” Christmas cactus, just have a look at the leaves!
Buying Christmas cactus
Christmas cacti can be found in most garden centres and plant stores during the holiday season and might also be sold in supermarkets and other shops. Keep in mind that the stress of transport might unfortunately cause them to lose their lovely flowers.
You can also buy a wide variety of Christmas cactus colors and cultivars online on Amazon.
Propagating Christmas cactus
Propagating a Christmas cactus is not a difficult task and can be done by taking cuttings. Just twist off a segment containing a few leaves, let it dry for a few days and stick it into a new pot (or the old pot if your aim is to give your plant a “fuller” look). It should root and start producing new growth within a few weeks.
