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 cool, brief day cycle. It takes at least eight days of 16 hours of darkness and 8 hours of light per 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 cool room 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.
Do zygocactus and Christmas cactus look alike?
Thanksgiving cactus is also known as zygocactus (Schlumbergera truncata syn. Zygocactus truncata). During the holidays, it is offered as “Christmas cactus,” “Thanksgiving cactus,” and “holiday cactus” at various retailers. The Schumbergera x buckleyi, or “true Christmas cactus,” is not widely advertised. Christmas cactus blooms around Christmas, whereas Thanksgiving cactus blooms in late November. Cultivars differ. The purple, pink, or white blossoms of the tropical Thanksgiving cactus are a response to the late-shorter fall’s days and cooler weather. Thanksgiving cacti are winter-hardy in USDA plant hardiness zones 10 to 12, but they are typically grown as indoor plants. With the exception of their serrated edges, the little, flat green stem segments are smooth. Like many desert cactuses, this one lacks spines. The tops of the highest segments are where the flower buds develop.
Christmas cacti are they cacti or succulents?
While poinsettias continue to be the most popular Christmas flower, Christmas cacti (Schlumbergera bridgesii) are also highly well-liked. Since the 1800s, Christmas cacti have been grown as seasonal plants. French botanist Charles Lemaire created the first Christmas cactus, which he named after Frdric Schlumberger, a French horticulture collector. Although their actual botanical name is Schlumbergera, they are most usually referred to by their previous moniker, Zygocactus. Cherry-red flowers on the original hybrids bloomed around Christmas time.
In southeast Brazil, the ancestors of the modern Christmas cactus were found in 1819. Schlumbergera truncata, the first to be discovered, blooms in October and November and is now known as the “Thanksgiving cactus.” Another, known as the “Easter cactus,” Schlumbergera russelliana, was found in 1837 and blooms from February to April. These two combined to create the first “Christmas Cactus.” These plants have somewhat varied leaves in addition to flowering at various periods. Thanksgiving cacti feature pointy teeth, whereas Christmas cacti have flattened leaves with rounded teeth on the borders. Easter cacti feature leaf joints covered with fibrous hairs and sharp teeth.
In different hues and combinations of white, pink, red, fuchsia, and more infrequently, orange and yellow, there are about 300 hybrid variants. This plant, which really blooms in the winter, belongs to a family of epiphytic cacti that originated in the South American rainforests. Despite what its name suggests, the plant is not a genuine cactus and is not as drought-tolerant. It is a succulent plant, though, and its leaves can hold a respectable amount of water.
In addition to being well-liked holiday gift plants, Christmas cacti are frequently a point of contention among gardeners. They can and do flourish for many years when given the proper care. Plants that are 40 or 50 years old frequently outlive their owners. They are frequently given to the following generation of the family, such as Aunt Mary’s Christmas Cactus or Grandmother’s plant. During their yearly flowering cycle, these long-lived plants can grow to be several feet tall and produce hundreds of blooms. They also acquire what appears to be bark.
Regarding care, upkeep, and especially how to encourage these unusual tropical cacti to bloom again, there seems to be a lot of misunderstanding. The cultural prerequisites are same for all of the holiday cacti. Thought of being heat-loving plants, Christmas cactus actually retain their blossoms longer in colder climates. Homes are frequently dry, and the Christmas cactus enjoys humid environments. Placing the pot with the drip pan on top of a small container packed with pebbles is one approach to increase the humidity specifically for your cactusis. Pour water on top of the pebbles, making sure that it doesn’t go past the bottom of the top layer of stones. As the water evaporates, the humidity level around the cactus will rise. Keep the plant away from drafts from fireplaces, heat vents, and other hot air sources in a well-lit area. The flower buds on the plant may fall off before they have a chance to open due to drafts and temperature variations.
As a tropical plant, the Christmas cactus may really drop its flower buds if the soil becomes too dry. When the plants are stressed by drought, they will wilt. When the top inch or two of soil seems dry to the touch, water it thoroughly. The amount of time between watering sessions will change depending on the relative humidity, air temperature, amount of light, and growth pace.
Although most gardeners like the challenge of keeping the plant beyond the holidays so it can rebloom the next year, the plant doesn’t really need to be fertilized while it is in bloom. Use a fertilizer made for flowering houseplants while the plants are actively growing and adhere to the label’s feeding recommendations for quantity and frequency.
While the Christmas cactus can tolerate low light, plants that have been exposed to higher light intensities tend to produce more profuse flowers. Indoors, keep your plants in a bright area. In the summer, plants can be carried outside, but do so in a shady or somewhat shady area. If leaves are exposed to too much light, they may begin to turn a little crimson. The leaves may actually burn if they receive too much direct sunshine, or they may grow limp. When it comes time to bring the plants back inside in the fall, gradually increase the number of hours they spend inside each day to help them become used to living indoors.
If your plant tends to dry out and/or wilt frequently, it may be time to repot the plant into a slightly larger container. Avoid going overboard with the larger pot size; Christmas cacti flower best when they are little pot-bound.
Christmas cactus requires soil that drains well. For succulent plants, use potting soil that has been professionally packed or make your own by mixing two parts ordinary potting soil with one part clean sand or vermiculite. Your Christmas cactus will branch out more if you prune it after it blooms. Pinch off a few pieces of each stem with your fingers or a sharp knife to remove them. To grow new plants, these pieces can be rooted in damp vermiculite.
The thermophotoperiodic Christmas cactus is a type of plant. A specific ratio of day duration and temperature is required for the bud to form. These plants will start to bloom in the Northern Hemisphere when the length of the day is roughly equal to the length of the night and when the temperature is between 50 and 60 degrees F. If given lengthy, continuous dark periods—roughly 12 hours each night—Christmas cacti will bloom. To have plants in full bloom by the holidays, start the dark treatments about mid-October. For 6-8 weeks, or until you see buds growing, you can place the plants in a dark closet from around 8 p.m. until 8 a.m. each night. Christmas cacti can blossom without the dark treatments if they are exposed to cool temperatures of around 50 to 55 degrees F. If chilly treatments are initiated by early November, plants should blossom in time for the holidays. Happy holidays and healthy gardening!

Are Christmas and crab cacti the same thing?
The Christmas cactus, Thanksgiving cactus, and Easter cactus stocks come out in the fall and winter. They are not the same cactus, even though they all normally bloom in the cooler months. If you’re unsure whether you have a Christmas or Thanksgiving cactus, ask yourself: It makes sense to ask the question. These two types are somewhat distinct from the Easter cactus. With a few pointers, differentiating between the three is comparatively easy.
Schlumbergera, a genus of cactus, includes the Christmas and Thanksgiving cacti. They are both short day cacti, thus for them to bloom, there must be extended intervals of cool weather and night. Before setting buds, both of these plants require six weeks of chilly, gloomy circumstances with at least 12 hours of daylight every day. Are Thanksgiving cactus and Christmas cactus the same thing? Each belongs to a different species and has a unique leaf structure.
The Schlumbergera truncata, often known as the Thanksgiving cactus or Crab cactus, has clawed margins on its leaves. Christmas cactus Schlumbergera bridgesii has notched but less sharp edges. Apart from the holiday cactus’ different leaf types, they both feature tubular, vividly colored flowers.
Do Epiphyllum and Christmas cactus look alike?
Fans of the Epiphyllum refer to them as “Eppies,” which are epiphytes.
Epiphyllum, sometimes known as “eppies,” are commonly referred to as orchid cacti due to their massive and exquisite blooms. Their blossoms, unlike those of actual orchids, typically only last a few hours, but fortunately, they frequently have numerous over the course of a few days or weeks, giving you a chance to carefully examine them as they go through their transformations.
Where do Epiphyllum Grow?
The habitat that they have evolved in will give you some ideas of the conditions that these plants like; give them good drainage and high organic matter in their soil, and bright but filtered light and your Epiphyllum will be happy.
Schlumbergera, or Christmas Cactus, Rhipsalis, Hatiora, and a number of other closely related genera are related to Epiphyllum, as are other jungle plants that grow high in the tree tops. They occasionally interbreed to create novel and fascinating hybrids.
How to Propagate Epiphyllum Cuttings
In no time, you’ll catch the propagation bug and start producing your own hybrids.
I spent a few years in the 1990s working at the now-defunct Fletcher Greenhouses in Tomslake, British Columbia. Dick and Sheila Fletcher were the owners, and they propagated a large number of exquisite Epiphyllum from cuttings as well as from seeds.
The seeds are produced inside a red fruit that is then removed from the plant to ripen and dry before being harvested for consumption.
They don’t require stratification or any other kind of treatment because they are a tropical plant and can germinate right away.
