Pruning is an essential element of plant care. Many people think they can simply plant Christmas cactuses whenever they like and leave them to grow on their own.
However, over time, these same people often find their plants becoming wild and unkempt, growing a lot slower than they did initially.
The truth is: pruning not only helps maintain the shape and appearance of your plants but also encourages healthier growth and more blossoms.
Let’s go over some of the common and uncommon signs that suggest your Christmas cactus may need pruning!
7 Signs That You Need To Prune Your Christmas Cactus
7. Overgrown Or Leggy Appearance
If your Christmas cactus appears to be running wild and has long, thin stems with leaves barely hanging on around the top, it’s definitely in need of some pruning.
The dullness of the plant will be apparent to you and it usually doesn’t take a trained eye to notice that.
Ask yourself, “Does my Christmas cactus look thinner, weaker, or somewhat untidy?” If you find yourself answering yes, it’s time to trim it back.
6. No Blooms? It’s A Sign!
If you notice flower buds on your Christmas cactus but no blooms whatsoever, that’s definitely a sign you should bring out your pruning shears and get to work.
Poor blooming could mean your plant has unproductive stems and weak foliage that needs to be removed in order to reduce unnecessary stress and help the plant thrive.
5. Yellowing Stems? You Must Prune!
Yellowing Christmas cactus stems means they are weakening or perhaps already dead. In most cases, the underlying cause happens to be a fungal disease that was silently spreading throughout the plant and has now started to affect the stems.
To limit spreading and keep this fungal infection from affecting other stems and areas of the plant, it’s best to trim down all affected stems as soon as possible.
4. Crowded Or Tangled Growth
If your Christmas cactus has become overwhelmingly dense and seeing the tangled mess causes you stress, it’s time to prune and thin it out.
Tangled stems and foliage limit air circulation throughout the plant and substantially raise the chances of attracting a fungal disease. Your Christmas cactus also won’t be able to absorb as much light due to the crowded foliage, likely resulting in weaker blooms.
3. Stunted Growth? That’s A Bad Sign!
Is your Christmas cactus growth very weak and slow? Some trimming might help.
Though it may seem counterintuitive to trim down a plant with weaker growth, pruning can actually promote rejuvenation and vigor, leading to healthier, long-term growth.
But, it’s very important to prune carefully and only remove stems or leaves that appear discolored or weak. Trimming down too much can stress your plant, limiting growth even further.
2. Unbalanced Shape
This is probably the easiest sign to recognize when it’s time to prune. You don’t need a trained eye or be an expert to notice an unbalanced plant shape.
If your Christmas cactus is moving farther away from the ideal shape you had in mind for it, pruning is necessary to bring it under control and give it a tidier, more presentable look.
In some cases, only certain areas of the plant may be producing uneven growth, causing the entire plant to look unbalanced. This is another clear sign that your cactus needs pruning.
1. Pest Or Disease Issues
If you’ve been experiencing pest and disease issues for some time now, you may need to prune your Christmas cactus if you’re serious about getting rid of them.
Thinning down your plant will make it harder for these little garden monsters to establish themselves and infest, indirectly driving them away from the plant.
How To Prune Your Christmas Cactus Safely?
Step 1: Prune Your at the Right Time
Generally, it’s a good idea to prune Christmas cactus around springtime or right after it completes a blooming cycle.
Step 2: Spot Dead or Weak Areas for Trimming
Carefully assess your plant and spot dead or weak areas that will need trimming.
Step 3: Make Precise Cuts
Using clean and sharp pruning shears, make cuts on the selected stems and leaves, ideally where the segments meet.
Step 4: Remove Stems and Leaves
Gently pull off the stems and leaves, making sure not to damage the healthy surrounding foliage.
Step 5: Monitor Your Plant
Closely monitor your plant for the next few days. After pruning, it will need lots of care and attention. Ensure proper hydration and that all other needs are being met.
Conclusion
These days, people on the internet tend to overcomplicate everything. In my view, and in the eyes of any wise gardener, pruning Christmas cactus is a simple task.
Yet, the online world makes it seem complex and confusing. Just watch for the signs that your plant needs pruning, and with a gentle touch, get the job done.
My Thanksgiving cactus is only blooming on one side. There are short clades in the middle that never bloom or get new growth. What’s wrong with it?
Hi Linda!
It sounds like your Thanksgiving cactus might need more even light exposure or a bit of pruning to encourage growth in the center. Rotate the plant regularly to ensure all sides get bright, indirect light. You can also prune a few of the longer clades to stimulate new growth in the middle. A little balanced fertilizer during the growing season can help, too. 🌵🌸
Pictures would be very helpful and much appreciated. It would help folks understand what you mean by leggy or brown at least I know I’d appreciate it.
Hi Renee!
Thanks for your feedback! We’ve updated the article to include pictures for each issue, like leggy growth, to make it easier to understand. Hope it’s helpful! 😊
The leaves are purple 😢
Hi Renée ! 😊 Purple leaves on a Christmas cactus usually mean it’s getting too much direct sun or it’s stressed from cold temps. Try moving it to a spot with bright but indirect light, and make sure it’s not near a cold window or draft. The purple should fade back to green once it’s in a better spot!
So, we should not cut them like your first picture shows and not like the Facebook post picture?
It’s a little confusing.
Hi Maryann!
Great question! The pruning method depends on the specific issue your Christmas cactus is facing. You likely won’t need to prune it as shown in the pictures unless your plant has a significant problem. Check out the list of common issues below to identify what your cactus might be experiencing. At the end of the article, we guide you through “How To Prune Your Christmas Cactus Safely?”. Hope this helps clarify things! 🌵🌸
-Yes it is confusing. I think a video of someone pruning would help
Hi Maryann!
Does all this info include the Easter cactus?
Hi! Great question! 😊 While Easter cactus are similar, they have slightly different care needs. But, if you’re wondering about pruning, the same rules generally apply! Let me know if you need more details! 🌿✨
I have my great grandmother’s cactus but it doesn’t bloom I don’t know what to do
Hi Ranae! That’s so special! 🌿✨
Christmas cactus need cool nights, shorter daylight hours, and a little neglect to bloom. Try keeping it in a cool (50-60°F), dark spot for 12-14 hours a day for about 6 weeks. Water sparingly and avoid moving it once buds form. I also have a helpful article on caring for Christmas cactus check it out here: How To Water & Fertilize Your Christmas Cactus For Lasting Blooms!😊🌸
I have several thanksgiving cactus with multiple seed pods from this year. Should some of them be removed
Hi Debbie!
Seed pods take a lot of energy from the plant, so if you want to encourage more blooms and healthy growth, it’s best to remove most of them. You can leave a few if you’re interested in collecting seeds, but otherwise, pruning them off will help your cactus thrive! 😊🌿✨
My Christmas Cactus look wilted. I only water when dry.
Hi Donna! 😊 That happened to mine too! It turned out the soil wasn’t draining well (even though it felt dry on top). I repotted it in cactus mix and gave it a good drink, bounced back in a week or two. Check if it’s rootbound or if the soil’s gone compact!
Like to start one from a friends how can I do it?
Hi Ed! 😊 It’s super easy! Just ask your friend for a few stem segments (2-3 sections each), let the cut ends dry for a day or two, then stick them in some slightly moist potting soil. They root pretty quickly. I’ve started tons of plants this way from friends and family!
I’ve actually got a whole step-by-step guide on it here: How to Propagate a Christmas Cactus: A Step-by-Step Guide!
Mine bloomed like crazy this year. After it finished I noticed it was really sagging. I touched it and huge pieces started dropping off. I’m trying to root them in water now and I’ve repotted it. It’s still not looking as healthy as it did before it bloomed. I’m so disappointed.
Hi Deb! 😊 Aww I totally get that, mine did the same after a big bloom one year. It’s like they give it their all and then need a recovery break 😅 Rooting the pieces in water is a great move! I’d let the main plant rest in bright, indirect light and go easy on watering for a bit. Fingers crossed it bounces back soon! 🤞
Same thing happened to me. My plant was thriving one minute and the next many segments have dropped off. I repotted and it still looks bad. I’m crushed.
Hi Jeanne! 😊 I’m sorry you’re going through this too, it’s so frustrating! Don’t give up yet. Sometimes after repotting they need a few weeks to settle in and can look rough for a bit. Make sure it’s not getting too much water (overwatering after repotting is common) and keep it in bright indirect light. Give it some time to recover, they can be surprisingly resilient. Hang in there!
Why is my cactus leaves turning purple? It just started doing this.
Hi Sherry! 😊 Purple leaves usually mean it’s a bit stressed, often from too much sun, cold temps, or needing a little fertilizer. I’d move it to bright indirect light and make sure it’s not getting too cold or too dry.
Do you have an article on how to deal with a root bound Christmas cactus?
Hi! 😊 Not a full article just on that yet, but I do cover repotting tips in my Christmas cactus posts! I go over how to handle a root-bound Christmas cactus in this post: 7 Reasons Your Christmas Cactus Won’t Bloom (And How to Fix Them). It explains when and how to repot without stressing the plant.
Also I am having trouble with my 2 split leaf philodendron- one is very old and 5 ft high and this summer started to get brown tips on the lower leaves and has now spread up the plant and many of the lower leaves have turned yellow. I suspect it is root bound. Should I cutoff the top green part and try to root in water and then replant and throw the bottom part away? If I cut off the top off where should I cut and how should I try to root it?
My second plant is the part I cut off last Spring as the plant was getting too tall- I tried to root it in water but this one didn’t seem to want to root- I finally got desperate as I was going away so stuck it in earth anyways. Now 6 months later the leaves are curling and it is not growing. Should I take it out of the soil and put it back in water to root? It is 3 ft tall.
What are those root like stringy projections that the plant grows and what should I do with them. Sometimes I cut them off- is that okay and sometimes they grow into the soil.
Hi Charlotte! 😊 For your split-leaf philodendron, yes, it’s likely root-bound. You can cut the top just below a node (where a leaf and those aerial roots meet) and root that piece in water or moist soil. Those stringy roots are normal aerial roots, I usually leave them unless they get unruly, since they help the plant absorb moisture and anchor when repotted.
My cactus has the yellow leaves in quite a few areas. Very old cactus that is much smaller now than years ago. The yellow is mostly on the outer tip leaves. You noted a fungal infection is the cause. Any tips on a cure beyond trimming.
Can this spread to other close by cactus? Both my other Christmas cactus show the same issues?
Hi David! 😊 Yes, fungal issues can definitely spread between plants, especially if they’re close together. Beyond trimming the yellow parts, make sure you’re not overwatering and that there’s good air circulation around your plants. You might want to separate them a bit and hold off on watering for a while. If it keeps spreading, a fungicide might help, but usually adjusting watering does the trick!
Based on online photos, the shape of the greenery indicates I have a Thanksgiving cactus. It never blooms, but the foliage is dark green. It is “spread out” looking though, with not much plant in the middle of the pot at all. All of the stems are around the outside of the pot. I tried giving it full darkness for 12 hours a day and cutting back on watering for the recommended 6 weeks, but still no blooms. I’m nervous about pruning/repotting, but I’d love for it to be healthy and bloom! What do you recommend? How do I know which action to take, and what should I do first? Thank you!
Hi Angi 😊 With a Thanksgiving cactus that’s dark green but never blooms, the most common issue is light or temperature during bud set. Even a little lamp light at night can stop buds. In early fall, try cool nights and true darkness every night for a few weeks. Since yours is spread out and bare in the middle, a light prune in spring can help it branch so you get more tip growth, which is where blooms form.
One quick question: is it near a TV, lamp, or kitchen light at night in fall?
I have 2 cactus that have stems coming out of the soil and they look and feel like wood. What is this all about.?
Hi Sandra 😊 Woody looking stems right at the soil line are usually normal “corking” as the plant matures. The only time I worry is if that area is soft, black, or mushy, which can mean rot. If it feels firm and the plant is growing fine, you can leave it alone and just focus on good drainage.
My cactus belonged to my mom. It has not been repotted in at least 20 years. It did flower this year and previous years. It has woody stems and is overgrown. I know tonrepot in late spring. Should I cut off woody branches? Should I take it to a nursery to repot? It’s quite large.
Hi Martha 😊 If it flowered and is healthy, I would not cut off the thick woody base stems. On older holiday cactus, that “woody” look is normal with age. Instead, prune the long floppy sections by twisting off a few segments at the joints to reshape it and encourage fuller growth.
Repotting in late spring is a good idea after 20 years, but go one pot size up and use a very fast draining mix. If it’s super heavy, a nursery can absolutely help you lift and repot it safely.
