The Christmas cactus brings cheerful winter blooms just when we need them most. With its dazzling pink and lilac flowers, this tropical beauty thrives indoors during the chill of winter. 

Whether you’re looking to keep yours blooming bright or share its charm by propagating new plants, this festive succulent is a gift that keeps on giving!

About Christmas Cacti

The Christmas cactus (Schlumbergera x buckleyi) is a popular houseplant that blooms indoors in the winter, so it’s popular at holiday time and makes a great gift, too. Unlike regular cacti, however, this is not a plant from a dry, hot desert location. Instead, this is a succulent native to tropical rainforests, where they grow on tree branches and soak up the high humidity, dappled sunlight, and warm temperatures.

The bottom line: Don’t treat a Christmas cactus like a run-of-the-mill cactus! It’s important to water these cacti regularly, but also to be cautious of keeping them too wet. (See detailed care instructions below.)

Holiday Cactus Types

There are three main types of “holiday” cacti out there: the Easter cactus (S. gaertneri), the Thanksgiving cactus (S. truncata), and the Christmas cactus (S. x buckleyi). For simplicity’s sake, we refer to all three species as “Christmas cactus” on this page since the care is the same. See our article on the different types of holiday cacti and how to tell them apart.

Planting

Potting Christmas Cacti

  • When selecting a pot for a Christmas cactus, be sure to choose one that has a drainage hole in the bottom. This helps to keep the soil from getting too wet.
  • Christmas cacti grow well in most potting mixes formulated for succulents. The important thing is that your potting soil drains well.

Where to Put a Christmas Cactus

  • Plants should be kept in bright, indirect light. An east-facing window or a bright bathroom is ideal. Too much direct sunlight can bleach the sensitive leaves.
  • A daytime temperature of 70°F (21°C) and an evening temperature of 60°–65°F (15°–18°C) is preferred.
  • Christmas cacti prefer a more humid environment, which makes a bright bathroom or kitchen a good spot to keep them.
  • In the summer, Christmas cacti can be placed in a shady spot in the garden or on an unheated porch until temperatures get below 50°F (10°C). Keep them out of direct outdoor sunlight.

Growing

How to Care for Christmas Cacti

  • Prune plants in late spring to encourage branching and more flowers. Simply cut off a few sections of each stem; the plant will branch from the wound.
    • If you wish, place the cut pieces in a lightly moist potting soil—they root easily after a few weeks and make for excellent Christmas presents!

How to Get Your Christmas Cactus to Bloom

The blooms of Christmas cacti and its relatives are triggered by the cooler temperatures and longer fall nights. The three main types of holiday cacti generally bloom according to this schedule:

  • Thanksgiving cacti are the earliest and longest bloomers, typically producing flowers from late fall through midwinter.
  • Christmas cacti tend to bloom from early to midwinter.
  • Easter cacti bloom from late winter to mid-spring.

If your cactus is NOT blooming, it may be receiving too much light or living in conditions where the temperatures are too high. Here are some tips to encourage yours to produce flowers!

  • To trigger blooming, nights need to be at least 14 hours long and days between 8 and 10 hours for at least 6 weeks. If you have strong indoor lighting that’s on at night, you may need to cover your cactus or move it to an area that’s exposed to the natural light cycle.
  • Flower buds form best when the plant is kept in temperatures between 50° and 60°F (10° and 15°C).
    • You can kickstart the budding process by exposing the plant to temperatures of about 45°F (7°C) for several nights in a row.
  • Make sure that you are consistent with watering while the plant is in flower. If the plant dries out too much, it may drop its buds.
  • If the cactus sheds its buds one winter, don’t worry—it should bloom the following year!

Pests and Problems

Blossom drop: If your Christmas cactus is exposed to any stress, it will likely drop its blossoms. This could be related to the amount of light or a sudden temperature change, as discussed in the above plant care section. Also, ensure your soil doesn’t get too dry while buds form.

The plant may be susceptible to mealybugs and, if overwatered, root rot. If you have problems, remove infected areas and repot in clean soil.

Water
Plan to water every 2 to 3 weeks, but only water when the top one-third of the potting mix feels dry to the touch. For example, if the plant is in 6 inches of growing medium, water when the top 2 inches feels dry. (Use your finger to check!) When the potting mix is sufficiently dry, soak it until water runs through the pot’s drainage holes. Place a tray underneath the pot to catch the water. After 10–15 minutes, discard any excess water in the tray so that the pot doesn't sit in water.

It's especially important to water well while the plant is flowering.
Fertilizer
From spring through early fall, feed every 2 weeks with a balanced houseplant fertilizer. Feed the cactus monthly in the fall and winter to encourage successful blooming.

Types

There are three main types of “holiday cacti” available:

  • Thanksgiving cacti (Schlumbergera truncata) bloom from late fall to midwinter and are often mislabeled as Christmas cacti.
  • Christmas cacti (S. x buckleyi) bloom from early to midwinter.
  • Easter cacti (S. gaertneri) bloom from later winter to mid-spring.

Wit and Wisdom

  • When the buds of a Christmas cactus look like they’re about to open, ensure you water the plant regularly and keep it cool.
  • Late spring is the best time to propagate cuttings because that’s when most holiday cacti emerge from their winter rest and initiate new growth.

My Christmas cactus bloomed early November this year. I kept on a covered porch here in sunny South Carolina and watered it well. Even split it up for present and it was gorgeous in doors as temps dropped. Now it looks overwatered and wilted blooms. ? I think I need to repot? Maybe set it outside again? Fertilize?

The plant is likely a bit too wet! Indoors with less light, it needs a lot less water than it does outdoors. It may also just need some time to adjust to indoors and bounce back on its own.

I jus received a Christmas Cactus - my first ever - so this page was extremely informative I love this plant and do not want to kill it!

I have a cactus that is at least 100 years old I acquired it in the 80s repotted it then because pot was cracked. Do they get root bound or do I not worry .. looks a little droopy now and leaves just don’t look right. My house is cold. Staring to bloom . So going to make sure it’s watered Any suggestion
<span>Cynthia</span> Mon, 09/04/2023 - 19:16
If you haven’t repotted it in 40 years it may be ready. I’m sure it takes C cacti long time to get root bound but 40 years might cover it.

I have had a Thanksgiving cactus for 5 or more years. It has never bloomed. What can I do to get it to bloom?
<span>Dawn Barone</span> Mon, 07/10/2023 - 08:24
My Christmas Cactus has never bloomed. It is in a small pot. Should I repot into what kind of a pot? Thank you for your help. Dawn

I have a Christmas cactus in my office and work 8am-5pm. To encourage it to bloom, I've started putting it in a box before I leave every day, and putting it back by the (east) window when I get back to work in the morning. What do I do about the weekends? I can't get into my building on weekends, so I either need to leave it in the box all weekend, or leave it out of the box. Suggestions?
<span>Millie</span> Sat, 12/03/2022 - 16:12
You should probably leave it in the box if you can't take it home due to boxes holding water longer

It would be best to leave it out of the box on the weekends!
