Thanksgiving cactus, holiday cactus, and crab cactus are all names for the Christmas cactus (Schlumbergera truncata).
A Christmas cactus blooms just once, right?
In November or December, your Christmas cactus plant blossomed profusely, and now you’re wondering if you’ll have to wait a whole year for it to bloom once more. The unexpected response is: Nope! The appropriate (and somewhat severe) conditions can cause holiday cactus to bloom once more after the season has passed. What must be done to ensure a repeat blossoming in February?
Are Christmas cacti seasonal bloomers?
Christmas cacti are highly common indoor plants, and for good reason too! They produce vibrant, tubular flowers that are pink or purple in hue when they bloom. They are a superb plant because of their lovely blossoms, lengthy bloom period, and simple maintenance needs. Someone in your family most likely owns a Christmas cactus!
About Christmas Cacti
The Christmas cactus (Schlumbergera x buckleyi) and its cousins don’t exist in hot, arid conditions like deserts or plains, in contrast to other cacti. These epiphytic succulents, which grow on tree branches and take in the high humidity, dappled sunlight, and moderate temperatures, are actually endemic to the tropical rainforests of southern Brazil.
Bottom line: Don’t handle a Christmas cactus like a typical succulent or cactus. They are unable to withstand the same kind of hot, dry weather that other cactus can. These cacti require more frequent watering than most succulents, but you also need to be careful not to overwater them. (See the care guidelines in more detail below.)
Thanksgiving, Easter, or Christmas Cactus?
The Easter cactus (S. gaertneri), Thanksgiving cactus (S. truncata), and Christmas cactus are the three main varieties of “holiday cacti” that are available (S. x buckleyi). The holiday that each cactus is named after often sees the most blooming. Thanksgiving cacti, which often bloom from November to February and hence go unrecognized as Christmas cacti, make up the majority of “Christmas cacti” sold nowadays. See our post on the several Christmas cacti species and how to distinguish them for more information.
Note: Because it’s the most widely used term and it applies to all three of these species, we’ll refer to all three of them on this page as “Christmas cactus” for simplicity’s sake.
Potting Christmas Cacti
- Choose a pot with a drainage hole on the bottom if you’re choosing one for a Christmas cactus. This prevents the soil from getting overly saturated.
- Most succulent-specific potting mixtures work well for Christmas cacti growth. It’s crucial that your potting soil drains properly.
Where to Put a Christmas Cactus
- Plants should be kept in indirect light that is bright. The best location has an east-facing window or a well-lit bathroom. The delicate leaves might be bleached by too much direct sunshine.
- It is preferable to have a daytime temperature of 70F (21C) and an evening temperature of 60–65F (15–18C).
- Christmas cacti do well in a more humid climate, so keeping them in a well-lit bathroom or kitchen is a smart idea.
- Christmas cacti can be kept in a shady area of the garden or on an unheated porch during the summer until the temperature drops below 50F. (10C). Keep them away from the sun’s rays outside.
How to Care for Christmas Cacti
- Water your plants every two to three weeks, but only when the top third of the soil feels dry to the touch. If the plant is in 6 inches of soil, for instance, water when the top 2 inches of soil feel dry. (Check with your finger!)
- When the soil is completely dry, wet it until water seeps through the drainage holes in the pot. To collect the water, put a tray underneath the pot. To prevent the pot from sitting in water, remove any extra water on the tray after 10 to 15 minutes.
- While the plant is in bloom, it’s very crucial to water thoroughly.
- Feed your indoor plants with a balanced houseplant fertilizer every two weeks from spring through early fall. Feed the cactus once a month in the fall and winter to promote fruitful blooming.
- To promote branching and more flowers, prune plants in the late spring. Simply cut a portion of each stem off; the plant will grow new branches from the incision.
- If desired, plant the cut pieces in potting soil that is only gently damp; they will easily root after a few weeks and make wonderful Christmas gifts!
How to Get Your Christmas Cactus to Bloom
The longer evenings and chilly weather of fall are what cause Christmas cacti and its relatives to bloom. The three major varieties of holiday cacti typically bloom on the following schedule:
- Thanksgiving cactus typically produce flowers from late October through mid-winter, making them the earliest and longest bloomers.
- Christmas cacti often bloom in the early to midwinter months.
- Easter cacti flower around the middle of spring through late winter.
If your cactus isn’t flowering, it can be getting too much light or being exposed to too much heat. Here are some suggestions to help you get blooms from yours!
- For a minimum of six weeks, the nights must be at least 14 hours long and the days between 8 and 10 hours. You might need to cover your cactus or relocate it to an area that is exposed to the natural light cycle if you have powerful interior lighting that is on at night.
- When the plant is kept at temps between 50 and 60F, flower buds form best (10 and 15C).
- By subjecting the plant to temps around 45F (7C) for a number of nights in a succession, you can jumpstart the budding process.
- While the plant is in bloom, be sure to water it consistently. The plant may lose its buds if it dries out too much.
- Don’t worry if the cactus loses its buds one winter; the following year it should bloom.
The three primary varieties of “holiday cacti” are as follows:
- Often mistaken for Christmas cacti, Thanksgiving cacti (Schlumbergera truncata) bloom from late October to mid-winter.
- Christmas cacti (S. x buckleyi) flower in the early to midwinter months.
- Late winter to mid-spring is the blooming period for Easter cacti (S. gaertneri).
- Make sure to water your Christmas cactus frequently and keep it cool when the buds on the plant appear ready to open.
- The optimum time to propagate cuttings is late spring when most holiday cacti start to grow after their winter hibernation.
Blossom loss: Your Christmas cactus will probably lose its blossoms if it experiences any kind of stress. As mentioned in the plant care section above, this could be caused by the amount of light or a sudden shift in temperature. Make sure your soil doesn’t become overly dry while buds are developing.
The plant could be vulnerable to mealy bugs and root rot if overwatered. If you experience issues, remove the affected sections and repot the plant in fresh soil.
How frequently do Christmas cacti bloom?
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. Beginner’s Guide To Plant Repotting.
What is a Christmas cactus called?
Christmas cactus, or hybrid Schlumbergera buckleyi, is a well-known cactus in the Cactaceae family that is grown for its eye-catching cerise flowers, which bloom inside around the time of Christmas in the Northern Hemisphere. The majority of Christmas cacti that are currently grown are thought to be hybrids between S. russelliana and the Thanksgiving, or crab, cactus (Schlumbergera truncata, originally Epiphyllum truncatum). It is native to Brazil, where it grows as an epiphyte in rainforests, primarily on trees or bushes but also in shaded areas among rocks. It is a member of the Schlumbergera genus. Zygocactus, the alternate name for the genus, is commonly used.
The Thanksgiving cactus and the Christmas cactus are sometimes confused, although the former has crenated (rounded) stem joint margins, and the latter has strongly saw-toothed stem joint margins. Thanksgiving cacti are frequently mistakenly marketed as Christmas cacti since they bloom in the late fall.
Is there a distinction between an Easter and a Christmas cactus?
The holiday season has here, which not only calls for decorations but also festive plants! At this time of year, there are many lovely holiday plants to pick from, whether they are bought from a florist, nursery, or are grown at home. The Christmas cactus is one of the most popular plants to give or receive at this time of year. Or is it a Thanksgiving or Easter cactus?
The three cacti differ from one another in terms of how their leaves are shaped. The edges of the leaves of the Thanksgiving cactus (Schlumgera truncata) are very sharply pointed and shaped like claws. The leaf projections of the Christmas cactus (Schlumgera bridgesti) are more scalloped or teardrop shaped. The edges of the leaves of the Easter cactus (Rhipsalidopsis gaertnerrii) are extremely rounded and centered.
These three cacti are all classified as short-day plants. Therefore, the plant needs low temperatures and 12–24 hours of darkness in order to bloom. If you overwintered your plant outside or bought it from a florist or nursery, you should keep it in a cold, dark place until the buds appear. The optimum location is an infrequently used bedroom or lower level. The Easter cactus gets its name from the fact that it takes 8–12 weeks of short days to bloom as opposed to the Christmas and Thanksgiving cacti’s roughly six weeks. It can be brought into a warmer environment once the buds start to form for your enjoyment. At this stage, a plant may occasionally start to lose its buds. That might be caused by air currents, warm temperatures, an abundance of water, or direct sunlight. Bright light is good for the plants, but not direct sunlight. Before watering, the soil should be completely dry to one inch below the surface. Fertilizing or repotting shouldn’t be done when the plant is in bloom. The plants appear to thrive when they are root-bound.
You might see the Christmas and Thanksgiving cactus bloom once more in the spring, though perhaps not as lavishly as over the holiday season. Simply restore the plant to its short day settings to promote springtime blooming.
Unless they are overwatered, these plants are generally disease-free. If the plant turns crimson, there is either too much sun, not enough phosphorus, or not enough water. There are rumors of plants that have been passed down from generation to generation for more than a century. Take advantage of these easygoing holiday plants and establish a new gardening custom.

Is it normal for my Christmas cactus to bloom in January?
“What went wrong when my grandmother’s Christmas cactus was about to bloom?
Martha
Hello Martha In addition, I “Right now, the Christmas cactus is flowering, so I’m loving the flowers and referring to it as my Winter cactus. In Missouri, these tough tropical plants require a little assistance in order to bloom on schedule. They have meteorological triggers in their native Brazil that cause them to blossom in December, the start of the South American summer.
If it was a gift from your grandma, your cactus might be the more mature, authentic Christmas cactus. Today’s market’s majority of cacti are actually Thanksgiving cacti, which explains why they often bloom at the end of November.
Look at the green fronds to identify the type of cactus you have. Thanksgiving cacti (Schlumbergera truncata) have sharp, jagged edges while the original Christmas cacti (Schlumbergera bridgesii) have smooth, round edges.
Since I put it outside on my back porch in the fall, mine has begun to blossom. Thanksgiving and Christmas cactus are “short day plants,” which means they need fewer daylight hours and/or cool nighttime temperatures in order to generate flower buds. The plants begin to form buds as the days become shorter and the nights get cooler in the fall.
Place your Christmas cactus indoors in a cool, light area where daily temperatures are 65–70 F and nighttime temps are 55–65 F if you want it to bloom when you want it to. Plants will blossom in about 5 to 6 weeks if they are exposed to colder night temperatures of 55 degrees Fahrenheit, sometimes regardless of how long the days are.
Since they bloom whenever they decide it’s the proper time, I don’t mind if they do so out of season. Perhaps you could write a note to Santa Claus as well?
Is it normal for my Christmas cactus to bloom in February?
At the Information Desk, we occasionally receive inquiries that appear more complicated than they actually are. “Why is my Christmas Cactus flowering in March?” was this week’s riddle. This is actually pretty easy to answer: Because it is an Easter Cactus and not a Christmas Cactus.
Most people imagine Christmas Cactus when they see this plant. By the end of the year, you can get them almost anywhere – in grocery stores, big-box retailers, or even in white, red, or pink hues.
Three distinct cactus from the same family have collectively come to be known as “Christmas Cactus.” What most people mistakenly believe to be a “Christmas cactus” is actually a Thanksgiving, Christmas, or Easter cactus. How do you distinguish between the two? Is it currently in bloom? Which month is it now? Is it early November, late December, or the end of winter/beginning of spring? You may get a major hint from that. The leaves, though, are where you can really tell them apart.
The leaf parts of all three plants are mushy and flat. The edges of the leaves on Thanksgiving cactus are longer and curled. The Easter cactus has only gently scalloped leaf margins, whereas the Christmas cactus has smaller, more right-angle-like projections. These succulents are part of the Schlumbergera genius of succulents (although Easter cactus has multiple accepted names: Schlumbergera gaertneri, Phipsalidopsis gaertnerii, Rhipsalidopsis gaetneri or Hatiora gaetneri). The Brazilian woodlands are home to all three.
These cacti have a very long lifespan and are frequently passed down within families from one generation to the next. This image is from a Bismarck Tribune article about a family’s cactus, which is 111 years old. Writer Ann Parr wrote about her family’s 150+ year old cactus in response to a news article about a 145 year old cactus owned by a family in Bozeman, Montana.
“Christmas Cactus” is a deceptive popular name. These plants are not drought-resistant, sun-loving cactus. Due to their native habitat of the treetops of Brazil’s coastal mountain ranges, they want bright, filtered sunlight and regular watering to prevent their potting soil from drying up altogether. They thrive in pots, which makes them much simpler to care for since they don’t need to be replanted.
They should be cared for like a houseplant once the blossoms have faded. They should be watered frequently and should be in bright light but not direct sunlight. If their pots are put in dappled shade, they are watered frequently, and they are taken inside before nightly lows of 50 degrees Fahrenheit, they can be cultivated outside during the summer. You may have a healthy, happy plant by fertilizing it once a year in late spring or early summer.
How to get Christmas Cactus to bloom again after the first year is the most typical query people have about them. Cooler temperatures and extended nights are necessary for blooms. Because they are short-day plants, these cacti bloom when it is a long, cool, dark night. For between 3 and 6 weeks, they require between 14 and 16 hours of nonstop darkness and 8 hours of daylight to form flower buds. You can either choose a room in your home that is rarely used at night and install them near a window, or cover streetlights and interior lights each night to maintain their required darkness cycle. It will be much better if the room’s temps are a little lower. Their preferred overnight temperature ranges from 50 to 68 degrees. You can return the plant to its original location in your house as flower buds start to form along the leaf edges so you can enjoy the blossoms.
Be cautious while including them in drafts. Bud decline may result from drafts. A few buds falling off is typical, but if the plant loses all of its buds at once due to a draft, you’re out of luck for another year.
