2 Secrets to Getting Christmas Cactus to Bloom + Care Tips

Some of the links in this post may be affiliate links.

Wondering why your Christmas cactus or Thanksgiving cactus isn’t blooming for you?  I will give you the secrets in this blog post that will make you successful.  It will work like magic!  And it’s so EASY that it is ridiculous!


I will also give you tips on growing and propagating your Christmas cactus as well. The care tips apply for both Christmas Cactus and Thanksgiving Cactus.

The care is the same and I will show you what the difference is too. Most places mistakenly sell Christmas Cactus as Thanksgiving Cactus.

Occasionally, you’ll just see both of these plants labeled as holiday cacti, but I show you later in this post how you can determine if your plant is a Christmas cactus vs. a Thanksgiving Cactus.

If you follow my tips in this post, you will have a beautiful, long-lived houseplant that will bloom for you every year. These are actually wonderful heirloom plants that you can pass along to future generations.

Before I get into the care, I have a little story about this plant.

While growing up in my parent’s house, I received cuttings of a Christmas cactus from my great aunt’s house and used those to make a new plant.  

I took care of it for over 15 years while I still lived in that house, and it grew into the largest Christmas cactus I had ever seen.  In fact, it grew so huge that part of the plant collapsed under its own weight!  

The plant had trailed probably 3 feet long. I should have taken it with me 🙁 But I left it with my parents.

It hung in front of a large sliding door, facing a Northern exposure, so it received plenty of bright indirect light.  

It was so huge that it remained in bloom for a solid 3-4 months!  Although I can’t promise you the same until your plant grows to mammoth proportions.

You’ll know if they are getting a little too much sun because their leaf segments will start to turn reddish.  If this occurs, your Christmas cactus is likely getting too much sun.


You can easily visually tell the difference between Christmas cactus and Thanksgiving cactus by looking at the stem segments.  The leaves are technical modified stems.

But we will call them leaf segments here…

The Thanksgiving cactus will have small pointy tips as you can see in the photo below. These belong to the species Schlumbergera truncata.

Christmas cactus segments will not have the tips and the segments will be rounder, and they tend to bloom a bit later than Thanksgiving cactus. 

They also tend to have a more pendulous growing habit than the Thanksgiving cactus.  Especially as the plant grows old.

Take a look at the rounder leaf segments with no points on the Christmas cactus below.

Christmas Cactus Care

Although they look a little different, the care is identical!  Many times though, they’re both labeled as Christmas Cactus when they are sold!


Christmas cactus (genus Schlumbergera), despite the name cactus, actually grow in tropical forests of Brazil.

They are actually epiphytes, similar to many orchids, so they’ll grow on tree branches instead of in the soil. And they actually ARE cactus! Except they are the jungle version of their desert cousins.

Christmas cacti, and the very closely related Thanksgiving cacti,  generally prefer bright indirect light, although some sun indoors is beneficial, especially morning sun.  Sufficiently bright light is important for blooming and overall health.

A northern window will do fine (especially if it is a larger northern window) and they can grow and bloom well even if you just have indirect sunlight, as I mentioned in my case earlier in this post.

An eastern facing window would work beautifully as well.

A west or south window would work as well as long as you can protect your plant from too much direct sun by using sheer curtains or slightly closed blinds if needed.

(I live in the northern hemisphere, so northern windows will get no direct sun and southern windows are sunny. If you live in the southern hemisphere, this will be reversed.)

Remember that leaf segments will turn reddish when they are getting too much sun and sitting in full sun all day.

Below is my Thanksgiving cactus that I propagated from my grandmother’s plant and that I’ve had for a few years now. It started as just small cuttings.

It is hanging in a south window however it doesn’t get a lot of direct sun because of an outdoor wall that is blocking the sun for part of the day, but it is a nice, bright window and it is thriving.

Water & Fertilizer Requirements

Ensure that your Christmas or Thanksgiving cactus has excellent drainage and is not sitting in excess water for long periods of time.  

Drainage holes are a must so make sure your pot as at least one, otherwise your risk of root rot will increase.

Since it is an epiphyte and grows on trees in nature, they demand excellent drainage.

I can’t recommend a frequency to water your plant, since it depends on your individual lighting and temperature conditions.  

Allow the top inch of soil to dry out before watering again, but at the same time, you should avoid letting the entire pot dry out.

Overly dry conditions will cause your plant to shrivel and wilt so try not to allow your potting mix to stay completely dry for too long.

As far as fertilizing, you can use any balanced water-soluable fertilizer for your Christmas cactus. I’ll continue to fertilize until about October or so.  Then I’ll refrain from fertilizing until new leaves start growing in the Spring.

My favorite all-purpose houseplant fertilizer is Dyna-Gro Grow which I purchase on Amazon.

It’s an amazing, complete, premium fertilizer that contains all the micro and macro nutrients that your plants need and I’ve achieved wonderful success using it!

Growing Medium

Any freely draining soil will work. My preferred soil mix is to use 2 part of an all purpose potting mix (you can even use cactus soil) with 1 part of pumice.


These plants grow in humid environments in nature, so naturally, it would be ideal to recreate this in the home.

If you have a small plant, you can place your plant on a tray of moist pebbles. You can also run a humidifier. Check out my detailed blog post on how you can increase humidity for your plants.

2 Secrets to Getting your Plant to Re-bloom

This is the million dollar question!  There are two main tricks to get your Christmas cactus or Thanksgiving cactus to rebloom in December or November or so (as the names imply).  


1. Plants Need a Certain Number of Hours of Darkness

The first is uninterrupted hours of total darkness at night.  If you have your plant in an area where you have lamps or any other lights on at night, this will deter your plant from blooming!

These plants need a dark period, and even if you have lights on for short periods of time.  They need evenings of complete darkness in late summer and Fall in order to set flower buds. This is probably the most important factor.  

You can also place your plant in a dark closet for 13-15 hours each night. At the end of each night, place it back in front of its window. If you want your plant to bloom during the holiday season or at Christmas time, count back about 8 weeks from the time you want blooming to start, and begin the darkness treatment until flower buds form.

Once buds start to form, you can leave your plant in front of its window and resume normal care.

2. Cool Temperatures at Night

The other factor that helps the plant set buds is cooler nighttime temperatures.  

Any drop in temperature at night would be helpful, with night temperatures in the 55F-65F range probably being ideal.

One way to achieve this is simply by placing your plant outdoors so that they are exposed to these lower night time temperatures for a few weeks.

Or if you have a cool room, that will work as well.

If you can have both the uninterrupted darkness and cooler temperatures, you should get quite a show from your plant.

It’s always fun to have my readers get back to me when their plants suddenly start blooming after I tell them what they need!  You’ll be surprised how quickly plants respond to proper care!


Christmas Cactus Propagation

Early spring to late spring is an ideal time for propagation. If your plant is blooming, you can wait until the summer months.

Propagating this plant is easy.  Just take a few cuttings and then place them in a jar of water.  Before you place them in water, allow them to air dry for a few days.

This will allow the cuts to dry and callous over so that the segments don’t rot. These plant are true cacti (although they are the jungle cousins and not from a desert!)

Roots will grow fairly quickly, and then potted them up in a good all-purpose potting soil.  You can add some perlite or pumice to the soil to improve drainage.

You could also put the cuttings directly into soil (after you let the cuttings air dry for a couple days). It is helpful to increase humidity while cuttings are rooting, and one easy method is to place a clear plastic bag over the cuttings.

Looking to purchase a special Christmas cactus? One of my favorite and most convenient one-stop-shops to buy practically any plant is Etsy. Check out the Christmas cactus selection (link to Etsy) today!

Why are my flower buds falling off?

One common complaint with these plants is bud drop. This can be caused by inconsistent conditions such as extremes in temperature or soil moisture levels.

I'm 74 years old and have both Xmas and Thanksgiving cacti. Mine summer on a roofed deck and get only early morning sun. I leave them out til the first of Oct (usda zone 6B -Pgh, Pa). At this point they have covered themselves with tiny buds smaller than a bb. I move them inside and place them in the windows. I don't wait til the buds are too large or the move may cause bud drop! I have quite a show every year and I look forward to it. Of course I have lots of other plants too. I collect geraniums that were popular in the Victorian Era - late 1800's.

Are these tips the same for "easter" cactus as well? I have a Thanksgiving cactus that puts on a lot of blooms every year but the easter cactus hasn't bloomed since I brought it home. They live in the same conditions.

My Christmas cactus leaves are looking shriveled!! Do you know why that might be. It's about 15yrs old and quite big. It's was my mother in law's. I'm reporting it as it needs it but any tips for the leafs would be lovely. Thank you

Hi Nicole! Did you feel the potting mix? That normally happens when it goes too dry or stays too wet.

I purchased my “Thanksgiving” cactus in December of 2019. Fast forward to April 2021. My “Easter” cactus has decided to bloom again for the first time since then and I am absolutely delighted. Go figure!!

I love unexpected surprises! Ha! :-)

I recently acquired a yellow thanksgiving cactus and was wondering what kind of soil you recommend for these? Something similar to the type of soil used for other tropical epiphytic cacti perhaps? Do these guys care what time of year they get repotted? I assume that their water needs might be higher then that of a desert cactus. Is that correct? Thank you!
