Two of the most popular holiday cactus varieties are Thanksgiving cactus and Christmas cactus. They are both easy to grow, and will rebloom year after year during the cold winter months! In this post, I show you how to tell the difference between these two popular plants, and share my holiday cactus care tips.
Once the summer is over, most of my houseplants are done with their active growing period and will rest during the winter. But, there are a few that are just beginning to come into their active growing season in the fall. Mainly the holiday cactus.
One of my favorite and easiest to care for houseplants are my holiday cactus plants. I love that they flower at an opposite time as most other plants. They add so much cheer and color into my house during the darkest, coldest months of the year! That’s why they made my list of the best indoor flowering plants!
Holiday Cactus Varieties
There are three main types of cactus plants that fall under the “holiday cactus” umbrella: Christmas cactus, Thanksgiving cactus, and Easter cactus.

Many people don’t know that there are two types of cactus houseplants that will start to bloom during fall and winter: Thanksgiving cactus and Christmas cactus.
People get Christmas and Thanksgiving cacti confused all the time because they look very similar.
However, there are subtle differences between these two common varieties. Once you know what to look for, it’s easy to tell them apart.

What’s The Difference Between Christmas Cactus and Thanksgiving Cactus?
Once you learn how to tell the difference between these two holiday cactus plants, you might be surprised to discover that the plant you’ve always referred to as your Christmas cactus is actually a Thanksgiving cactus (or visa versa).
One main difference between them is the shape of the leaf segments. Christmas cactus leaf segments are rounded, and Thanksgiving cactus leaf segments have sharper points.

Another difference between them is the timing of when they flower (which is how they get their common names!).
Thanksgiving cacti bloom in November, right around Thanksgiving time. Christmas cactus plants bloom sometime in December, close to Christmas time.

How To Care For Holiday Cactus Plants
Winter cactus plants have an opposite growing season than most houseplants do. They like to rest during the summer, and they flower in the fall or winter.
Usually, I will move my holiday cacti to a south facing window and start watering it more often in late August or early September in order to trigger the blooms.

After a few weeks, I will fertilize my winter cacti and leave them in the sunny location until after they’re done blooming. I recommend using an organic plant fertilizer for potted cactus plants, rather than a harsh chemical one. A general purpose indoor liquid fertilizer works great, or you could use compost fertilizer tea.
Once my plants are done blooming, I will slowly reduce the amount of water I give them and keep the soil on the dry side for the rest of the year.
In the early spring, I move my holiday cacti away from the sunny window so they can rest all summer.

How To Rebloom A Holiday Cactus
Cool nights and shorter days in the fall induce the blooming process to start for both Thanksgiving and Christmas cactus plants.
They should start flowering around the holiday they are named for, but sometimes they’ll bloom earlier or later if the timing is off. This is common, but don’t worry, it won’t hurt your plant.
Here are a few extra steps you can take when fall comes to help ensure that your holiday cactus will bloom beautifully…
- Keep the plant in an area where it gets bright, indirect light during the day, and complete darkness for at least 12 hours at night.
- Ideally, the temperature should remain around 50F degrees. But it’s more important that the evening temperature is cooler than it is during the day (aim for a 10F degrees or more lower at night).
- Reduce watering during this time, and allow the soil to dry out slightly (but never let it dry out completely).
- When flower buds begin to form, go back to watering the plant as you normally would.
- If your holiday cactus plant is outside, be sure to protect it from frost, or the flower buds could get zapped.
More Holiday Cactus Care Tips
- Keep your plants out of the sun in the summer, hot sun could damage the leaves.
- The best time to take cuttings for propagation is after your plant is done blooming.
- All types of holiday cacti like to be root bound, and will produce more flowers that way. If yours needs to be repotted, it’s best to do it in early spring. You can use a general purpose potting soil, or a succulent soil mix.
- Never overwater your plant. Keep the soil on the dry side when its not actively growing. During their active growth period (fall-winter), the soil should be kept evenly moist. If you struggle watering correctly, I recommend buying a soil moisture gauge to make it easy.
- These tough plants thrive on neglect most of the year.

I have some yellow, white and purple cactus however the leaves are pale and almost see thru. I’m trying lower light but they look the same. I live in zone 9/10 in Florida. I have my red and shrimp color high plants almost can’t put my arms around. I need help with my pale babies, any suggestions?

It sounds like your holiday cactus is getting too much sun. I recommend moving it to a spot where it doesn’t get any direct sunlight, especially if you have it growing outside. It can take some time for it to recover after moving it out of the sun. If the leaves have gotten sunburned, they will never go back to normal. They’ll likely eventually drop from the plant, but the new growth should be nice and green.

My thanksgiving cactus has been flowering for years but this year the leaves are shriveling up and dying. What can I do yo save it?
Amy Andrychowicz says
Shriveling leaves on your holiday cactus usually means the plant has been overwatered, but it can be caused by underwatering too. Check the soil to make sure it’s not wet. If it’s moist, then be sure to allow it to dry out completely before watering it again, and be sure the pot has plenty of drainage to prevent root rot. Also check the base of the stem to make sure it’s not rotting or mushy. Another thing that can cause holiday cactus plants to drop their leaves is when the air temperature is either too hot or too cold, or a if they experience a sudden change in temperature. So make sure the plant isn’t being exposed to cold drafts from a door or window, or that it’s getting too hot sitting near a fireplace or heat vent.

Hello! I’m trying to save a co-worker’s Thanksgiving cactus that hasn’t been tended to, other than over-watering. I’m going to take it home, inspect the roots, and re-pot it. What type of pot is best? One that drains well? The container it’s in now is a ceramic square with zero drainage.
Amy Andrychowicz says
Yes, put the Thanksgiving cactus into a pot that has drainage holes in the bottom for sure.
Marla says
Not sure which type we have as it is at work and we got a couple of propagated ones. They seemed severely root bound last year so I repotted them. They have never bloomed. Our work space stays around 67 degrees year around and sporadic light I g. Do you think they will do better with more direct lighting
Amy Andrychowicz says
Yes, consistent lighting would be better for it in order to trigger blooming. They need bright light during the day… but, they also need darkness at night in order to bloom. So, if the lights never go off in the office, then this may be the problem. If you want your holiday cactus to bloom, I would bring it home so that you can control the environment better.

I have a Christmas cactus I’ve had for several years it doesn’t grow it’s still the same size when I bought it it does bloom but doesn’t grow what should I do
Amy Andrychowicz says
As long as your Christmas cactus is healthy and blooming, then I wouldn’t worry that it’s not growing very fast. But you could try repotting it into fresh potting soil to see if that will help to trigger new growth.
Vivian says
I have a Christmas Cactus (I’ve had it for many years). Some years it doesn’t bloom at all, sometimes it blooms in August. It is starting to bloom right now. Should I put any fertilizer on it? I usually do once a month in spring & summer, but I’m not sure since it’s blooming!
Amy Andrychowicz says
It’s not uncommon for Christmas and Thanksgiving cactus plants to bloom during different times of the year than their named holiday. But, are you sure your plant isn’t an Easter cactus? They are another common type of holiday cactus that bloom in the spring, and their leaves look similar to a Christmas cactus. If you’re sure your plant is a Christmas cactus, I would not fertilize it right now. They have the opposite growing season than most houseplants, so your plant is probably confused. Move it to a spot where it gets indirect sunlight during the summer, slow down on watering, don’t fertilize, and allow it to rest. Then in the late summer/early fall, give it more light, start watering it more often, and slowly start fertilizing. If you do that every year, your plant should start behaving like a Christmas cactus again. LOL
Vivian says
Thanks so much for your advice. I’ve never seen an Easter cactus, so I’m not sure. It looks exactly like the Christmas cactus pictured.
