Christmas Cactus Care: Simple Steps for Success
Published: September 8, 2025 | Updated: September 18, 2026
If there’s one plant that knows how to make an entrance, it’s the Christmas cactus. Just when the days are short, the skies are gray, and you’re running dangerously low on holiday cookies, this cheerful houseplant bursts into bloom like it’s throwing its own winter party.
But as with any good guest, a little thoughtful hosting goes a long way. Fortunately, Christmas cactus care is fairly simple once you understand what the plant needs.
One quick note before we get started: Many plants sold as Christmas cacti are actually Thanksgiving cacti. I own both, and the good news is that their everyday care is nearly identical. So even if you aren’t sure which one is sitting on your windowsill, you can follow the care advice in this guide.
I’ll also show you how to recognize a true Christmas cactus and how to encourage your plant to bloom year after year.

Do You Have a True Christmas Cactus?
First, let’s figure out if you have a true Christmas cactus or its close cousin, the Thanksgiving cactus. Don’t worry if you aren’t certain.
Both are easy to care for, welcome additions to any houseplant collection, and their care requirements are very similar. Keep scrolling for helpful pictures that make the differences easier to see.
I grow both types myself because, if you’ve spent much time on this blog, you already know I’m a little plant obsessed! 😉
Thanksgiving cactus is much more common in retail shops because its stem segments are sturdier and less prone to breaking than those of a true Christmas cactus. Here’s how to tell them apart:
Stem segments: Look closely at the flattened green stems. Christmas cactus (Schlumbergera × buckleyi) has rounded segments with smooth, scalloped edges. Thanksgiving cactus (Schlumbergera truncata) has pointed, claw-like edges that give it a spikier appearance.
Bloom time: Thanksgiving cactus typically begins flowering earlier, often in November, while Christmas cactus tends to bloom closer to Christmas or later.
Flower form: Thanksgiving cactus flowers have a more upright or outward-facing appearance, while Christmas cactus flowers hang more gracefully from the stems, almost like ornaments on a tree.

Christmas Cactus Care
A Christmas cactus is wonderfully easy to live with, making it a favorite indoor houseplant for beginners and seasoned plant lovers alike.
Despite its name, it isn’t a desert plant at all. Christmas cactus hails from the tropical forests of southeastern Brazil, where it grows as an epiphyte on trees or tucked into rock crevices. Instead of baking in dry soil under intense sun, it receives filtered light and regular moisture, while its roots remain exposed to plenty of air.
That background gives us a helpful clue about Christmas cactus care. It prefers more water than a typical desert cactus, but its roots still need excellent drainage and should never remain soggy.
It thrives in bright, indirect light, but be sure to keep it out of harsh direct sun or the pretty stems can “sunburn” and turn a sickly purple color.
The stems also tend to be quite delicate. Unlike its sturdier Thanksgiving cactus cousin, the Christmas cactus has fragile stem segments that break easily. Avoid placing it in a high-traffic spot where people or pets might brush against it.
Watering: Water when the top inch of potting mix feels dry. Depending on the conditions in your home, this may be about every 1 to 2 weeks. Don’t allow the potting mix to dry out completely, and always use a container with drainage holes. Soggy roots make for a grumpy cactus!
Pruning: Pruning isn’t required, but it can encourage a fuller, bushier plant. Prune after flowering by pinching off stem segments with your fingers or cutting.
Repotting: Christmas cactus does well when slightly root-bound and does not need frequent repotting. Repot every 3 to 5 years, or sooner if the plant has outgrown its container or the potting mix has become compacted and drains poorly.
With the right care, a Christmas cactus can live for decades, sometimes even a century, and become a cherished family heirloom.

Christmas Cactus Soil Mix
In their native habitat, Christmas cacti are epiphytes, growing on trees and among rocks rather than rooted in the ground. They collect moisture and nutrients from rain and organic debris around their roots.
To recreate those airy conditions indoors, use a loose, well-draining potting mix. I use a simple blend of about 80% cactus potting mix and 20% perlite. The added perlite prevents the mix from becoming too dense and allows excess water to drain away from the roots.
Always choose a container with drainage holes, and allow the top inch of potting mix to dry before watering again. Avoid heavy soil or a pot that holds standing water, since constantly wet roots will quickly lead to root rot.

Important tip: If your Christmas cactus is sold in a plastic nursery pot covered with decorative foil, lift the plastic pot completely out of the foil before watering. Otherwise, water can collect inside the wrapper and leave the roots soaking wet.
Water the plant at the sink and let it drain completely before returning it to the foil. Follow the same routine with a decorative cachepot that doesn’t have drainage holes, and empty any water that’s collected inside of it.
Christmas Cactus Fertilizer
Feed your Christmas cactus during spring and summer, when the plant is actively growing. I use an all-purpose, water-soluble houseplant fertilizer such as Jack’s Classic All Purpose 20-20-20. It provides a balanced mix of the nutrients needed for healthy stems, roots, and future flowers.
Dilute the fertilizer according to the package directions and apply it about once a month. Stop fertilizing as fall approaches, and begin feeding again in spring when you see new growth.

Common Christmas Cactus Problems
Even an easygoing Christmas cactus can show signs of stress when something in its environment isn’t quite right. Watering, drainage, light, and sudden temperature changes are the most common causes.
Why Is My Christmas Cactus Wilting or Drooping?
Both overwatering and underwatering cause a Christmas cactus to wilt. Check the potting mix before reaching for the watering can. If it feels very dry and the stems look shriveled, water the plant thoroughly. If the soil feels wet and the stems are soft or limp, poor drainage or root rot may be the problem.
Why Is My Christmas Cactus Turning Purple or Red?
Reddish or purple stems are often a sign of stress. Too much direct sunlight is a common cause, but inconsistent watering, temperature extremes, or a lack of nutrients also contribute. Move the plant away from harsh sunlight and review its watering and fertilizing routine.
Why Is My Christmas Cactus Dropping Buds?
Flower buds sometimes drop when the plant experiences sudden changes in temperature, light, or moisture. Keep a budding Christmas cactus away from heating vents and cold drafts, water it consistently, and avoid moving it unnecessarily.
Why Is My Christmas Cactus Turning Yellow?
Yellow or soft stem segments often indicate that the roots are staying too wet. Make sure the container has drainage holes and allow the top inch of potting mix to dry before watering again. If the soil smells foul or the roots appear dark and mushy, the plant may have root rot.
How To Make a Christmas Cactus Bloom
With the right Christmas cactus care, you will be rewarded with gorgeous flowers year after year. Many people find that their Christmas cactus reblooms without any special effort at all.
Some lucky folks simply keep their cactus in the right spot without realizing it, and voila, blooms appear! But if your plant seems stubborn, don’t worry. There are tried-and-true methods to help coax buds into forming.
A little intervention might be in order, though some of the techniques sound more like an elaborate prank on your poor cactus!
The key is giving your plant 6 to 8 weeks of cooler temperatures, ideally between 55 and 65°F, combined with 14 hours or more of continuous darkness each night.
To create these conditions, you could move your Christmas cactus to a cool, dark closet or garage, or go the DIY route by placing a box over it every afternoon. Yes, it might feel a little ridiculous, but it works!
After this “neglectful" treatment, buds should start to form, and you can bring the plant back to its usual sunny spot just in time to show off its blooms for Christmas.
