The ground is covered with snow and winter is officially here. But wait! A glimmer of hope and sunshine are sure to appear amongst your houseplants. It’s time for your Christmas cactus to bloom!
But what happens when it doesn’t? How do you get a Christmas cactus to bloom? And how do you care for your Christmas Cactus afterwards?
Here are 5 common solutions you can try before you give up on your poor Christmas cactus.
P.S. the “Christmas Cactus” in the pictures is actually a Thanksgiving Cactus. I’ll explain more about that in point number five.
It’s Too Warm
Christmas cactuses need to experience a drop in temperature to tell the plant that it’s time to start blooming. If your plant is placed in a south facing window in the warmest spot in your house, try moving it to a north facing window or near a door. The cool air from the door being open and shut should send it the signals that winter is coming.
You Gave it Too Much Love Over the Summer (aka Stop Overwatering!!)
I never understood how much people love to overwater their plants until I started a gardening blog. While your Christmas cactus would like a drink every week or two, over the summer it can survive on neglect. It sounds counter-intuitive, but the plant actually needs a period of almost-drought to signal it to start blooming in the winter.
Lazy waterers, rejoice! Finally a plant that won’t die if you forget about it for a month.
However, you can’t forget about it completely. Once the fall hits, begin watering your cactus again at more regular intervals. After the blooms are done, you can ease back on watering again.

It Didn’t Need to be Re-Potted
Christmas cactuses actually like to be root-bound. Who knew?
Wait until the plant is 3-4 years old, or the roots start to grow through the drainage hole before you re-pot it. Select a pot that is only slightly bigger than your current pot. Finally, make sure you use a good quality potting soil that is made for succulents.
Never re-pot a Christmas cactus that is still blooming. It is best to wait until it is finished blooming, or until early Spring.
It’s Getting Too Much Light
Starting in October, the plant needs at least 12 hours of darkness to bloom. Unfortunately, artificial lights can mess with the 12 hours of darkness that are needed. The easiest way to solve this problem is to move your plant to a room in your home that is not often used during the evening.
It’s not Actually a Christmas Cactus
Did you know that there are actually three different types of cacti that look like a Christmas cactus? There is a Thanksgiving cactus, Christmas cactus, and an Easter Cactus. If you’ve tried everything in this post and still no blooms, you might just have a different cactus than you originally thought. To see the difference between the three, check out the picture on this pin. Also, sorry to the original poster, the link is dead or I don’t have access to it. If by chance you see this, I’d love to give you proper credit!!
