Thanksgiving cactus, holiday cactus, and crab cactus are all names for the Christmas cactus (Schlumbergera truncata). The leaf-shaped stem segments with curled, pointy teeth or claws around the margins are known as crabs. The leaf segments of the Easter cactus (Schlumbergera buckleyi) have rounded edges. They all came from wet, dark forests around the southeast coast of Brazil. Because they reside above ground in trees, where branches meet and decaying leaves and moss amass, they are categorized as epiphytes.
Although this plant has the moniker “cactus,” the maintenance it needs has nothing to do with its relatives in the desert. It is regarded as a type of woodland cactus. Its needs can be traced back to its beginnings. It is recommended for Christmas cactus to grow in “Potty trained That entails storing it in a small container for as long as possible before transferring it to a pot that is only marginally larger. They should not be allowed to dry out and like a thick organic potting mix. When the plant is blossoming, increase the watering. They favor direct, bright light. As the plants start to burn in full light, the leaf segments might turn a dark red color.
The “The two factors of light and temperature are the key to getting Christmas cacti to bloom in the years after purchase. These two hold the secret to the realm of flowers. Flowers are produced by Christmas cacti during a chilly, brief day cycle. It takes at least eight days of 16 hours of darkness and 8 hours of light every day for flower buds to begin to form. No matter where the plant is located, avoid using the lights at night, even for a little time. That ends the necessary dark cycle. Around 61 degrees should be the ambient temperature. Place the plant away from drafts of either cold or hot air.
All that is required is to set the Christmas cactus on the window sill in a chilly area without turning on the lights. In a brightly lit space, a plant’s side towards the window will frequently sprout buds, but not the other way around. It usually has to do with either receiving too much or not enough water or with there being insufficient humidity in the air if the plant sets flower buds and then they fall off. The good news is that if their temperature and light needs are met, Christmas cacti are thought to be rather simple to induce to bloom once more.
Why isn’t my Christmas cactus flowering?
Due to its short day length, the Christmas cactus cannot blossom due to drought stress or excessive light exposure. Christmas cacti are adapted to wet, frequently rainy jungles. If the conditions are dry or there are too many hours of sunshine during bloom production, it does not flower.
I’ve listed here a few other reasons that can stop the Christmas cactus (Schlumbergera) from flowering:

How can a cactus be made to bloom?
How do I get my houseplant cactus to bloom? When I bought it, it was in bloom, but it hasn’t since. -Beth
Because we can’t supply as much light as a sun-drenched desert, it can be difficult to encourage desert cacti (the spiky sort) to bloom indoors. Two more critical elements for blooming are light and:
Age: Some plants mature over several years. Purchasing an already-blooming plant is the greatest method to verify this, as you did.
Dormancy: In response to a chilly, dry, dormant phase, many desert cacti blossom. You should transfer your cactus to a cooler location with plenty of sunlight during the winter, around 50 degrees Fahrenheit, and restrict watering to just once a month—enough to prevent the plant from shriveling up.
Additionally, bear in mind these pointers for year-round cactus maintenance:
Cacti thrive indoors best on a south-facing windowsill or in a sunroom. They will receive the most sunlight, and in the winter, the air around windows is typically colder than that inside a room.
Your cactus need the most light and warmth throughout the growing season (spring and summer). Put your plant in full sun and rotate it so that it receives even illumination.
During the growing season, more water will be required. Before giving the plant a good watering till the water flows out the bottom, let the top two inches of soil dry off (empty the drainage tray). Never leave your plant in moist soil; instead, picture a brief desert downpour that quickly dries in the sun.
Use a cactus-specific fertilizer or a very diluted fertilizer that is lower in nitrogen and higher in phosphate and potassium to fertilize cacti only in the spring and early summer. Your cactus won’t blossom if you feed it too much!
Use a potting mixture made for cacti and succulents to repot your cactus. After repotting, give your cactus a week without watering.
How often does a Christmas cactus bloom each year?
Whichever one you have, it’s possible for them to bloom more than once a year. For Your Reference, Here Are A Few Of Our General Houseplant Guides: Watering Indoor Plants: A Guide.
Will a Christmas cactus naturally bloom?
Give your loved ones a gift they will cherish for years to come, season after season. This lovely zygocactus, sometimes known as a Christmas cactus, is available in cheery hues and sizes. Watters Christmas Cactus is a lovely flowering plant for the holiday season with a swirl of hues in shades of golden, pink, red, and white. Just in time for the Christmas celebrations, our head grower has a keen sense of color. The vibrant colors that these blossoms offer will delight you.
You might believe that a cactus would make a unique Christmas plant. In the middle of winter, the Christmas cactus (Schlumbergera bridgessii) is a most welcome sight when it is covered in blossoms.
Your Christmas cactus will bloom on its own with very little maintenance. It might not, though, bloom in time for the holidays. You must force your plant into dormancy around 8 weeks before you want flowers if you want it to be fully displayed throughout the holiday season. Although it seems difficult, it really doesn’t take much work. Remembering to do it is the most difficult part.
GETTING YOUR CHRISTMAS CACTUS TO BLOOM
You’ll probably need to encourage your Christmas cactus out of dormancy and force it to bloom in order to have it blossom at Christmas.
Reduce watering by mid-October. Just water when the ground feels dry, which is usually about an inch below the surface. When forcing, avoid fertilizing.
Maximum Light
Reduce the quantity of light the plant receives gradually. The plant can continue to get indirect sunlight throughout the day, but at least 12 to 14 hours of complete darkness are required for the flower buds to open at night. (If the temperature in the room is higher than the recommended 50 to 55 F, add a few more hours of darkness each day.) Your Christmas cactus should be placed in a closet or room with a door that is kept closed at night. You will also need to take the extra precaution of covering the plant with a dark cloth or bag if light leaks in from under the door. Keep doing this treatment for six to eight weeks. You ought to then notice flower buds forming on the stems.
Once you spot blossom buds, take your Christmas cactus out of the shadows and place it close to a bright window. Make sure it is not near any drafts or it will lose its buds due to the cold.
Within a few weeks, the flowers ought to begin to open. The plant should continue to bloom for four to six weeks, and each blossom should remain open for at least six days, if not longer.
GROWING TIPS
The Christmas cactus is a native of tropical rainforests, in contrast to the desert-loving cacti that many of us are accustomed to, and it need frequent water to stay healthy.
Grow your Christmas cactus as a hanging plant or set it somewhere with space for it to dangle to stimulate new stems. Don’t be concerned about bumping into it. The plants of the Christmas cactus lack thorns.
- Although Christmas cacti have been known to bloom lavishly when placed in a bright, frosty window, they prefer diffused light. They can easily adjust to changing growing environments.
- Water the plant well, letting the extra liquid drain through the drainage hole. Between waterings, let the soil almost fully dry out. Never allow moist soil to stand. When the leaves begin to pucker and shrivel, the soil is too dry.
- The Christmas cactus also requires humidity, especially in the dry conditions of warm dwellings. Either spray the plant or set a tray of stones in water underneath it. The water should not come in contact with the pot’s bottom.
- Feed Watters Root & Grow at half the suggested strength once a month as fertilizer. When the buds form, withhold this cactus feeding; continue it after flowering.
- The Christmas cactus doesn’t care too much about the temperature. They prefer temperatures between 70 and 80 F. 55 to 65 F during the growing season and during setting buds.
OTHER TIPS
- Avoid opening doors frequently and drafty windows. They dislike rapid drafts and, if exposed to them, will shed their buds or flowers.
- After flowering, minor pruning gives the plant new life.
- If Christmas cacti are maintained slightly pot confined, they tend to bloom better.
- If your Christmas cactus blooms occasionally throughout the year, don’t be shocked. That’s what a joyful Christmas cactus does.
- This plant has an incredibly long lifespan and is simple to grow from cuttings.
- Older plants bloom even more frequently than young Christmas Cacti do.
- Neglect seems to be beneficial for Christmas cacti. Avoid the urge to fuss over them.
When should you put a Christmas cactus in the dark?
Put your Christmas cactus in complete darkness for at least 12 hours every day, beginning in October, to start blooming. In time for the holidays, the plant will have around eight weeks to develop buds and blossom as a result. To encourage your Christmas cactus to bloom again in February after the holiday flowering time, keep up this same pattern.
How long can a Christmas cactus live?
Christmas cacti can survive up to 100 years or longer if given the right care. Even news stories of families passing on their Christmas cacti to future generations as living heirlooms have been documented, such as this one about a particularly resilient plant that dates back to the 1860s. Wow!
The majority of Christmas cacti, however, only live for 20 to 30 years with proper care, despite the fact that they can last for decades and brighten your home every holiday season. By that time, the plants typically perish from widespread problems including overwatering, underwatering, freezing weather (if they spend part of the year outside), pests, illnesses, loss of interest, or simple neglect.
Help, my Christmas cactus is yellowing!
Yikes! Your watering routine is typically to blame if your Christmas cactus doesn’t seem to be growing well. These creatures require more water than desert cacti, but they also don’t want their soil to be wet.
You’re probably not watering your Christmas cactus enough if the leaves are becoming wrinkled and appear withered. You possibly overdid it if they’re more mushy and yellow-black in color. To get rid of any rotten roots and repot your plant in dry soil, you might need to uproot it.
Why are the leaves on my Christmas cactus limp?
Wilted leaves are frequently caused by improper watering because it is simple to provide too much water (rather than not enough). A Christmas cactus’ weak or drooping leaves are typically the result of either damp soil or root rot. If you have one issue, it will almost certainly lead to another.
Make sure that any extra water you give your Christmas cactus drains slowly but steadily through the drainage holes. If not, your potting soil may be too dense and may not be working. To promote aeration, you can repot the plant in bromeliad soil or fluff it up with perlite.
During the spring through winter growing season, keep the soil lightly moist; only water when the top inch of soil feels dry to the touch. After the flowering season is over, it’s good to allow the soil get a little bit dry in the middle of winter between waterings, but don’t let it get completely parched.
Is a Christmas cactus toxic to cats and dogs?
I’ll keep this short: no. The ASPCA states that Christmas cacti are not dangerous, despite the fact that ingesting any plant may cause some mild vomiting or diarrhea.
Should my Christmas cactus be misted?
Contrary to what its name might imply, Christmas cacti can survive well into the following year. In fact, with a little care and our guidance, they can live for up to 20 years.
Christmas Cacti need cooler temperatures.
Leaving Christmas cacti in a space that is between 60 and 70 degrees Fahrenheit will cause them to bloom more fully and sooner. Keep them away from radiators, fireplaces, and warm windowsills, especially during the winter.
While they don’t need the heat of the sun, they do need its light.
The hard part comes at this point. A Christmas cactus needs lots of sunlight but cannot be kept in direct sunlight as it will dry out. So what should a cactus aficionado do? Your best option is to leave it in a part of your home that is shaded (or outdoors once summer arrives) and rotate it occasionally.
Just like you and I, Christmas cacti need their rest.
Your cactus needs between 1215 hours of uninterrupted darkness per day if its buds haven’t yet set. Cacti only require lots of light once their buds have fully developed.
You should be misting, not watering, every day.
Your cactus will die if you overwater it. But that doesn’t mean they never experience thirst. You should mist your cactus every day rather than watering it like you would a regular plant. You only need a few sprays from a spray bottle to maintain your cactus’ happiness. Only when the soil at the base of the plant feels entirely dry to the touch should you water it.
Christmas cacti need nutrient-rich soil.
Christmas cacti are strong plants that can endure harsher environments, although well-drained soil that has some organic matter is preferable for them. While organic soil is always available to purchase, you can also use your cacti as a little compost and add organic waste that you would typically discard.
