If you’ve been giving your Christmas cactus all the love in the world only for it to reward you with a whole lot of green and absolutely no flowers, you’re definitely not alone.
These plants can be a little dramatic when it comes to blooming. They don’t just need decent light and the occasional drink of water. They respond to a few very specific cues, and if even one of them is off, those buds may never show up!
The good news? Most of those factors are completely within your control, and once you know what your Christmas cactus is actually waiting for, getting it to bloom becomes a whole lot easier.
So, Why Is Your Christmas Cactus Being So Stubborn?
If you’re one of the lucky people who does absolutely nothing special and still gets a Christmas cactus covered in flowers every year, congratulations. We’re not all blessed with such a cooperative plant.
For the rest of us, blooming usually comes down to a few specific things like night length, cooler temperatures, and the right care before buds form.
If yours looks healthy but refuses to flower, start with these seven things.
Tip 1: Don’t Wait Until December to Panic
December is around the corner, Christmas cactus photos suddenly start popping up all over your Facebook feed, and then it hits you. “Wait… what about mine?” You look over and there it is. Green, healthy, and showing absolutely no sign that Christmas is coming.
Unfortunately, this is where a lot of people start too late. If you want blooms around the holidays, you should begin setting the right conditions in late September or early October.
So start early. A Christmas cactus usually needs about six weeks of long nights and cooler temperatures to start forming buds. It does not respond well to last-minute holiday planning, and honestly, neither do I.
If you prefer having the whole season mapped out, we also wrote a month-by-month Christmas cactus care guide that explains what to do leading up to the holidays.
Tip 2: Give It a Proper Bedtime
If there’s one thing that can make the difference between a Christmas cactus that blooms and one that just sits there looking green, it’s what happens after the sun goes down.
Christmas cactus use long nights as a signal to start forming buds. Think of it as mimicking nature, where nobody is switching on a lamp or watching Friends at 2 a.m.
For the most reliable results, give it 14 to 16 hours of uninterrupted darkness each night for about six weeks in the fall. And when I say uninterrupted, I mean it! Even a lamp or hallway light can interrupt that dark period, so a spare room that stays dark at night works perfectly.
Just remember: long nights do not mean darkness 24/7! Your Christmas cactus still needs plenty of bright light during the day, which brings us to Tip 3.
Tip 3: Don’t Put It in Plant Jail
Before you take Tip 1 too literally and send your Christmas cactus into solitary confinement, remember that the darkness is only for nighttime.
During the day, it still needs bright, indirect light. An east-facing window is usually a great spot, or anywhere it gets plenty of light without being blasted by harsh afternoon sun.
If yours spends summer outdoors, keep it in partial shade or filtered light. Too much intense sun can scorch the green segments, but too little daytime light won’t help those future blooms either.
And if yours is starting to look pale or washed out, we also wrote an article explaining whether light is actually the problem or if something else is going on.
Tip 4: Give It the Cold Shoulder
Your Christmas cactus actually likes things a little chilly when it’s getting ready to bloom.
Night temperatures around 55 to 65°F can help encourage bud formation. And no, this does not mean squeezing it between the milk and leftovers in the fridge!
A cooler room or corner of the house works perfectly, as long as it still gets bright light during the day. If nighttime temperatures stay above about 70°F, bud formation can become much more difficult.
If you’re like me and your feet turn to ice the second the house drops below 70°F, I feel you… Unfortunately, your Christmas cactus has other plans. For a few weeks, one of you is going to have to be uncomfortable. And unless you’re planning to bloom in December, I’m afraid it’s you.
Finding that sweet spot can be tricky, so we also put together a guide on exactly where to place a Christmas cactus for the best chance of blooms.
Tip 5: Don’t Drown It or Forget It Exists
Don’t let the word “cactus” fool you. Christmas cactus is not a desert cactus at all. In fact, it naturally grows in the humid forests of Brazil, which is about as far from a hot, dry desert as you can get.
That means it likes more moisture than you might expect. While buds are forming, water when the top inch of soil feels dry, then let the excess drain completely.
I like to water mine from the bottom. I let the pot sit in a shallow tray of water for about 10 to 15 minutes, then take it out and let it drain thoroughly. It gives the potting mix time to soak up what it needs without leaving the roots sitting in water.
Quick tip: The trick is consistency. Let it get bone-dry and developing buds may drop. Keep it soggy and the roots can suffer. Basically, don’t drown it and don’t ghost it either.
If watering these plants still feels like a guessing game, we have a full guide on how to water a Christmas cactus without ending up with root rot.
Tip 6: Once Buds Show Up, Leave It Alone
This is the point where doing less can actually help more. Once those tiny buds appear, DON’T START MOVING IT AROUND! Trust me, I know that urge, but you need to resist it.
No moving it to a prettier window. No rotating it because “this side needs more light.” No carrying it into another room because you suddenly decided the temperature feels better there.
Christmas cactus can be surprisingly dramatic about sudden changes in light, temperature, drafts, or humidity, and the punishment can be dropping the buds you waited weeks to get.
So once it starts budding, find a good spot and leave it there. You’ve done your part. Now back away slowly and go get yourself a cup of coffee.
Tip 7: Give It a Haircut After the Party
Christmas cactus actually benefits from a little pruning, but timing matters. The best time is after it finishes flowering, not when you’re trying to get it to set buds in fall.
Simply pinch or cut off one or two segments from the ends of longer stems. This encourages the plant to branch, and more branches mean more stem tips where future flowers can develop.
Just don’t get carried away. You’re giving it a haircut, not preparing it for the military. A light trim is usually all it needs.
If you’re staring at yours wondering whether it actually needs a trim, we also wrote a guide on the signs that tell you it’s time to prune your Christmas cactus.
What If Your Christmas Cactus Still Won’t Bloom?
So you started early, gave it long nights, kept it cool, watched the watering… and your Christmas cactus is still sitting there completely green and completely unbothered.
These plants can be stubborn. Sometimes it feels like no matter how nicely you ask, bribe, or negotiate with them, they simply have other plans. Mine has also skipped a year before, just to keep me humble, and that’s okay. I may or may not have threatened it with the compost pile, but we worked through it…
One last thing: many plants sold as Christmas cactus are actually Thanksgiving cactus or hybrids, which can naturally flower earlier. So if yours bloomed beautifully in November and has nothing left to prove by Christmas, it may not be misbehaving at all.
That doesn’t mean fertilizer never matters, though. We wrote a month-by-month Christmas cactus fertilizer guide if you want to know when feeding actually helps and when it’s better to leave the plant alone.
May the Buds Be With You
At the end of the day, Christmas cactus are a little dramatic. You can do everything right and they may still decide this is the year they need to keep you humble.
One last tip… Give it your best shot, and if it refuses to bloom, don’t let it see you panic. Plants can sense weakness.
When is it the right time to bag Christmas cactus to help humidity? How long is plant bagged for?
Hi!
The best time to bag a Christmas cactus to help with humidity is when you notice the environment is too dry, especially during winter when indoor heating can lower humidity levels. You can bag it when the soil is slightly dry, but make sure the plant is healthy and not too wet, as excessive moisture can lead to rot.
Typically, you can bag the plant for a few days to up to a week. Just make sure to check on it regularly, and once the air feels more humid or the plant perks up, you can remove the bag. Be sure to keep the bag loosely covered to allow some air circulation. This little boost in humidity can help your Christmas cactus thrive! 🌵💧
I put mine in the closet for 30 to 40 days, then put in daylight.
Hi Pat! 😊 That’s a great method, that dark rest period really helps trigger buds. I do something similar every fall, and it never fails to get blooms!
You don’t water it? You actually ignore it then? I have a bedroom in the basement im thinking would work. Its never used. Its not cold but dark in there unless I go in and turn on the light? What do you think? Thx
Hi Sandra 🙂 You should still water it during the bloom-prep period, just less often. Check the soil and water when the top inch feels dry. That basement bedroom could work for the 14 to 16 hours of darkness at night, but the cactus still needs bright indirect light during the day, and cooler nights around 55 to 65°F will make blooming much more reliable.
Did you water it when you have it in the closet?
I am happy to say my cactus is 3. This month. Last year it had 3 blooms. This year I fed it Miracle Grow in July and Sept. Due to renovation in my house, since the first of the month, it has been in direct sunlight. It also has 23 buds and is starting to bloom. I have been spritzing it every mid morning for 2 weeks not knowing it needed humidity. When is the best time to transfer/repot it into a bigger pot?
Hi Marilyn! 😊 That’s fantastic, sounds like it’s thriving! I’d wait until it’s completely done blooming before repotting, usually in late winter or early spring. That gives it time to rest and adjust without losing any buds.
I have mine in the bathroom no light only when someone’s in there showering, loves the humidity and darkness
Hi! 😊 It might enjoy the humidity, but it still need bright, indirect light to stay healthy and bloom. Maybe move it near a bright window and it’ll do even better!
Hello
I bought a beautiful I believe Christmas cactus I believe there’s two types. It had a few flowers, but it never bloom for me. It’s bushy and green and doing good but I have no idea what to give it to bloom or what to do. Will it bloom in the spring and what is the best fertilizer that might help it bloom? Easy stuff, please I’m not good with plants.
Hi Shelley 🙂 Easy version: give it bright indirect light, let the top of the soil dry a bit before watering, and give it long dark nights for several weeks to trigger buds. A balanced houseplant fertilizer is fine during active growth, but don’t overdo it.
I would like an answer to that question I’ve sprayed my cactus in the summer and it’s finally growing
Hi! 😊 That’s great to hear it’s growing again! Spraying during summer is perfect, it keeps humidity up when the air’s dry. Bagging is more for winter if your home gets very dry from heating, so you’re doing just fine with misting right now.
Mine had little dry brown patches on the leaves and I am not sure what I did wrong.
Hi Monica! 😊 Dry brown patches are usually from inconsistent watering, either it dried out too much between waterings or it’s getting too much direct sun. Make sure you’re keeping the soil lightly moist (not soggy) and check that it’s not sitting in harsh direct light. Should bounce back once you find the right balance!
II have all my cactus on my breeze way by windows the light is indirect. This year it’s been very humid and mushrooms are growing in my plants. What should I do.
Hi Tami 🙂 The mushrooms themselves usually aren’t hurting the cactus, but they’re a sign that the potting mix is staying quite moist. I’d remove them, improve the airflow, and let the top of the mix dry before watering again. Also make sure the pots drain freely and aren’t sitting in water.
What do you spray it with? Do you just spray it with water?
I do not spray my cactus. I run water through the soil and let all the water drain out. I water around 1 1/2 weeks apart
I have recently repotted a 15 year old Thanksgiving cactus. Should care for this plant be the same or different than your normal recommendations. Should I expect it to bloom this year or will it likely take time to recover & not bloom.
Hi Lana! 😊 After repotting, give it a little recovery time, keep watering light and light bright but indirect. It might skip blooming this year while it settles, but it should bounce back beautifully next season.
1/2 of my Christmas cactus turned very limp and the fell off. The other 1/2 is still standing upright. What did I do and what do I do to stop it from happening again?
Hi Dianna!
It sounds like your Christmas cactus may have experienced stress, possibly from overwatering or a sudden temperature change. Check the roots—if they’re mushy, it could be root rot. Trim any damaged roots and repot in fresh, well-draining soil. Water when the top inch feels dry, and keep it in a stable environment with indirect light. This should help the healthy part thrive! 🌵
I have an old Christmas Cactus that my Mother in law gave me when we first got married over 60 years ago. It is big but only 2 stems are left and it hasn’t blossomed for several years, it needs help.
Hi Frances!
How special to have a 60-year-old Christmas Cactus! Try repotting it in fresh fresh cactus or orchid mix to give the roots a boost. Give it bright, indirect light, and let the soil dry between waterings. For blooms, give it cooler temperatures (around 50-55°F) with 12-14 hours of darkness each night for 6 weeks in fall. It may bloom again with a little care! 🌵🌸
I guess my Christmas Cactus will never bloom. We don’t have anywhere in our house where it’s that cold. We can’t live in a house like that, even though it would be nice for the heating bill. We live in northern Ohio, the garage is way too cold.
Hi Jim! 😊 You can still get it to bloom! Just give it about 12–14 hours of darkness each night for a few weeks, even in a warm house that helps trigger buds. A cool room or closet works great for that.
Have you thought about taking a clad(leaf) and let it root in water or you can also put in dirt to root and you will have another plant from MIL❤️
Hi Terrie! 😊 That’s actually a great idea. Propagating a few segments is perfect if she wants to keep her mother-in-law’s plant going strong. I’ve done that with cuttings from family plants, nice way to refresh them while keeping the legacy alive!
Maybe too much water?
I loved this info. I’m trying to get my two to bloom. Southern Calif. I now have them in a dark bedroom with one window and no sun exposure!
Hi Linda!
I’m so glad you found the info helpful! Keeping your Christmas cactus in a dark room with minimal light is a great start. Just be sure they get a cool temperature (around 50-55°F) and limited water for about 6 weeks. That should help trigger blooming! 🌵🌸
I have a Christmas cactus,and want to get it to bloom. I.have no sun light so I bought a light on a stick that lights up,It is used for plants how long should I leave the light on each day??? I really want to get it tobloom. Read about putting g a bag over it_ ,so I just did that, how long do I leave the bag on??
Hi Carol!
To get your Christmas cactus to bloom using a grow light, leave the light on for about 8-10 hours a day. The plant also needs a period of complete darkness for 12-14 hours each night, which mimics its natural blooming cycle. You can remove the bag during the light period and put it back on at night if you’re using it to ensure darkness. Keep this routine for 6-8 weeks, and you should start seeing buds forming. Best of luck—it sounds like you’re giving it great care! 🌵🌸
When should I put my cactus in the closet at night during the day and how long to help it bloom I’ve never heard of putting it in the closet, but I’ll try it if it’ll help it bloom it’s bushy and green. Had two pink flowers when I bought it at Christmas time and no more flowers after that.
Hi Shelley 🙂 You can put it in a dark closet overnight for about 12 to 14 hours, then bring it back out to bright indirect light during the day. Do that for several weeks, and keep it away from lamps or room lights at night.
My Christmas cactus are getting buds. It’s mid October, what can I do to make them bloom later?
Hi Diane!
To delay your Christmas cactus blooms, you can try reducing the amount of light they receive. Move them to a darker area or cover them for 12-14 hours a day for a couple of weeks. Keep them in cooler temperatures, around 50-55°F, and reduce watering slightly. This will help slow down the blooming process, so they flower closer to the holiday season! 🌵🎄
It is probably a Thanksgiving cactus, not a Christmas cactus. The leaves are different.
Hi Carol!
You might be right, thanks for pointing that out! Diane, you could also have a Thanksgiving cactus, not a Christmas cactus. The leaves are a bit different—Thanksgiving cactus have pointed, claw-like edges, while Christmas cactus have smoother, rounded edges. They also bloom earlier, which could explain the October flowers. 😊
Yes I have a Thanksgiving cactus. It has double blooms.
This is great information. I am trying to keep mine alive. Half died from root rot. It is about thirty years old. How do I start a new plant from it? Also, do you have any tips for growing a money tree plant? I have killed two. Working on the third one. Maybe too hot in Florida. Same with my Christmas cactus.
Hi!
First of all, taking care of a Christmas cactus for 30 years is amazing! 😊 To start a new plant from it, you can take a healthy cutting, about 2-3 segments long, and let it dry for a day or two. Then, you can either place it in water to root (just make sure the water stays fresh) or plant it directly in well-draining cactus soil. Both methods work, but if root rot has been an issue, you might prefer starting it in soil to avoid overwatering.
As for your money tree, they can be finicky in hot climates like Florida. Keep it in bright, indirect light, avoid direct sun, and ensure the soil stays moist but not soggy.It might help to increase humidity around the plant or move it to a cooler spot. It sounds like you’re on the right track, so don’t give up! 🌵🌱
I just wanted you to know I have my great great great grandmothers Christmas cactus so its got to be over 100 years old and it blooms at Christmas and at Easter pretty cool huh!
Hi Darla! Wow, that’s absolutely amazing!!!! 😲 A Christmas cactus that’s over 100 years old, passed down through so many generations—that’s a true treasure! And the fact that it blooms at both Christmas and Easter makes it even more special. What an incredible piece of family history to have in your home! 🌵🌸
wow!!!!! thats history!!!
Hi Julie!
Buds falling off before blooming is usually a sign of stress, often due to changes in light, temperature, or watering. Try keeping the cactus in a stable environment with consistent care—bright, indirect light, and avoid overwatering. Also, make sure it’s not exposed to drafts or sudden temperature shifts. A little extra care should help those buds hold on and bloom! 🌵🌸
When you say place in a bag, is it a paper or plastic bag?
Hi Terri! You can use either a paper or plastic bag. If using plastic, make sure it’s not sealed too tightly to allow some airflow and prevent moisture buildup. Both work to help your Christmas cactus bloom! 🌵🌸
I have 2 Christmas cactus about 40 yrs old and they bloom every year and have 2 piece lollies that are 27 yrs old that are great .
Hi Loretta! 😊 Wow, 40 years is amazing! My mom still has one from my grandma that’s decades old too, and it just keeps blooming. They really do reward you if you treat them right year after year!
I would like to know how you repot a fairly large Christmas cactus without breaking the leaves
Hi Darlene! 😊 For a large Christmas cactus, I’d wait until after it finishes blooming, then carefully tip the pot on its side and gently work it out. The leaves are more flexible than they look, but go slow. You can also prune it back a bit before repotting to make it easier to handle, just take a few stem sections off and you can propagate those too!
I placed my outdoors cactus in a portable greenhouse during a day of heavy rains. The next day it was droopy and had turned brown. What did I do wrong?
Hi Linda! 😊 Sounds like it got too humid inside the greenhouse, cactus don’t like trapped moisture. Let the soil dry completely and move it back to a bright, airy spot.
I have the hardest time deciding when to water and fertilize my Thanksgiving cactus.
Hi cma1166! 😊 I totally get that, they can be fussy! I only water mine when the top inch of soil feels dry, and I feed it lightly after flowering ends, not while it’s blooming.
Love your information. I have a cactus that has stems about 2 feet long. Is that too long and should I cut it back? It does bloom every year but only on the window side. East facing. I would love to repot it but it is too long. How long should I let the stems be?
Hi! 😊 Sounds like it’s doing really well! You can trim those stems back a bit after it finishes blooming, that helps it branch out and bloom more evenly. I usually keep mine around 12 to 18 inches so it’s easier to manage and repot.
My Christmas cactus is covered with buds…but it’s outside on the porch and I have to bring it in. It has suddenly turned quite cold at night. I live in Massachusetts. What can I do to keep it from dropping the buds??
Hi Lynne! 😊 Bring it in before the nights drop too low, the sudden chill can shock it and make it drop buds. Try to move it somewhere bright and cool indoors, and keep the light and watering steady so it adjusts slowly.
I have what I think is a Thanksgiving cactus because the leaves spikes. It has always had plenty of blooms from mid November until mid January. This year the plant looks different…almost like it is 3 plants It has never been repotted simply because everything I have ever repotted has died a slow death afterwards. I welcome any advice or suggestions you may have.
Hi! 😊 It does sound like a Thanksgiving cactus! If it’s never been repotted, it might just be a bit crowded, I’d move it to a pot only one size bigger in fresh soil after it finishes blooming. Don’t worry, they usually bounce back quickly with gentle handling.
I kill all my plants but my christmas cactus is blooming so beautiful after just looking at it for a year. I just watered it, root bound in a little pot and its grown so good n beautiful.
Hi Marcie! 😊 That’s awesome! They really do love being a little root-bound, sounds like you’ve found the perfect balance for it. Keep doing exactly what you’re doing! 🫶
Good practical advice!
Hi Don 😊 I’m glad you liked it!
My cactus has a bad odor but it’s green. I took it to the local flower shop last summer and had them repot it. The soil is like a brick but I water it every 2-3 weeks. They put it in a container with no drainage. Not sure what to do with it. It is in an east window so just gets light in the am and shaded the rest of the day. Thanks for any advice.
Hi Sue 🙂 A bad odor plus no drainage is a concern, even if the plant is still green. I’d move it to a pot with drainage and fresh, well-draining cactus mix, then check the roots for any mushy or rotted parts before replanting.
I love the information you supplied. My question is I thought I bought a Thanksgiving cactus. It bloomed the next year. I started to water it in March and within a few days buds came on it to be in bloom for Easter. Is this normal or is the plant confused?
Hi Sylvia 🙂 That can happen, and your plant isn’t necessarily confused. Thanksgiving cactus can bloom more than once when they’re happy and get the right light and temperature signals. They’re also often mislabeled, so comparing the leaf shape and flowers online can help you tell whether you have a Thanksgiving, Christmas, or Easter cactus.
I have little knots flying around my cactus is this a concern how can I get rid of them
Hi 🙂 Those sound like fungus gnats. They’re usually a sign the soil is staying too wet. Let the top of the soil dry more between waterings, remove any soggy debris, and try yellow sticky traps near the plant.
My friend gave me a Christmas Cactus last year, one she had repotted.. it bloomed at Christmas, really pretty. It has continued growing, but has gotten really leggy, not sure if I should trim it or let it be. I occasionally fertilized and try to keep it lightly watered in an East window in my sun room. When should I start taking in to a dark area at night?
Hi Joan 🙂 That east window sounds like a good spot. Since it’s already late summer, I’d leave the leggy growth alone for now and trim it after flowering, which will encourage more branching. For Christmas blooms, start around late September or early October and give it at least 12 hours of uninterrupted darkness each night for about 6 weeks.
Trying my luck for my first Christmas cactus this year.
Hi Diane 🙂 I hope you have lots of blooms this year! The biggest thing is giving it those long, uninterrupted nights in fall, so you’re starting at just the right time to learn its routine. Hope you get tons of blooms 🤞
I have a Christmas Cactus that was my grandmother’s. I’m 86 years old, so it’s pretty ancient too. If i start covering it with black plastic and it sets buds, do I continue covering it at night?
Hi Ruth 🙂 Once you can clearly see buds forming, you can stop the nightly dark treatment and keep the cactus in bright indirect light. I’d avoid black plastic because it can trap heat and moisture. A dark room, closet, or breathable cover is safer, and once buds appear try not to keep moving the plant around.
My plants (5) of them are doing good. I have them outside, where they get morning sun. I live in Puerto Rico and it’s hot all the time. In the beginning of October I move them to a small guest room all night. My question is should I open the window or put the a/c on. Last year they bloomed beautifully.
Hi Lucy 🙂 Since you’re in Puerto Rico and your nights stay warm, opening the window may not cool the room enough to encourage buds. I’d use the A/C if needed to keep the room around 60-65°F at night, but don’t have cold air blowing directly on the plants. Keep giving them uninterrupted darkness at night, and since they bloomed beautifully with this routine last year, I’d stick pretty close to what worked. Once you see buds forming, stop moving them back and forth and keep their conditions as steady as possible.
