The origin of the Christmas cactus is entrenched in hot, tropical conditions in Brazil, adding to the mystery. Christmas cacti are a Schlumbergera family plant that blooms during the Christmas season in the Northern Hemisphere. They flower in April to May in their native location, and the popular name has no meaning. Crab cactus is the name given to them in Europe because of its clawed limbs.
Schlumbergera is divided into six species. Several of these are labeled as “holiday” cactus in commercial production. The Thanksgiving and Christmas cactus plants are named for the fact that they bloom from September to February and are forced to bloom and sold as gift plants during the Thanksgiving and Christmas seasons. The genus name honors Frederic Schlumberger, a French exotic plant species collector. Allen Cunningham discovered the group of holiday cactus in the early 1800s, and by the 1900s, there were multiple hybrids.
What is special about Christmas cactus?
While poinsettias remain the most popular Christmas holiday gift plant, Christmas cacti (Schlumbergera bridgesii) are also popular.Christmas Cacti have been preserved as a holiday plant since the 1800s. The original Christmas cactus was created by French botanist Charles Lemaire and named after Frédéric Schlumberger, a French horticulture collector. Although Schlumbergera is the true botanical name, they are more commonly referred to as Zygocactus, which was its previous name. The original hybrids blossomed over the Christmas season and sported cherry-red blossoms.
In the year 1819, the forerunners of today’s Christmas cactus were discovered in southeast Brazil. Schlumbergera truncata, the first to be discovered, blooms between October and November and is now known as the “Thanksgiving cactus,” whereas Schlumbergera russelliana, identified in 1837, blooms between February and April and is known as the “Easter cactus.” Apart from blossoming at different times, these plants have slightly distinct leaves: Christmas cactus have flattened leaves with rounded teeth on the margins, whereas Thanksgiving cacti have sharp teeth, and Easter cacti have pointy teeth with fibrous hairs in the leaf joints.
Since this plant is really a winter-flowering houseplant, it is one of a group of epiphytic cacti native to the South American jungles. It is not a true cactus and is not quite as drought tolerant as the name implies, but it is a succulent plant and can store a reasonable amount of water in the leaves.
Christmas cacti are not only popular holiday gift plants, but they are also the subject of much debate among gardeners. Properly cared for, they can and do thrive for many years. It is not uncommon for 40- or 50-year-old plants to outlive their owners, and they are frequently passed down to the next family generation, i.e. grandmother’s plant or Aunt Mary’s Christmas Cactus.
We typically think of cacti as heat tolerant, but Christmas cacti will keep their blossoms longer in cooler temperatures. The Christmas cactus prefers humid conditions, yet homes are often dry.
Because the Christmas cactus is a tropical plant, it will drop flower buds and wilt if the soil becomes too dry. Water thoroughly when the top inch or so of soil feels dry to the touch. The length of time between watering events will vary depending on the air temperature, amount of light, rate of growth, and relative humidity.
While the plant does not require fertilization while in bloom, most gardeners enjoy the challenge of keeping the plant after the holidays for re-bloom the following year. Use a blooming houseplant-type fertilizer and follow the label directions for how much and how often to feed while the plant is actively growing.
While the Christmas cactus can adapt to low light, plants that have been exposed to more light intensity produce more abundant blooms. Keep your plants in a sunny location indoors. Plants can be moved outdoors in the summer, but keep them in a shady or semi-shady location. Excessive light can cause the leaves to turn a bit red. Too much direct sunlight can actually burn the leaves or cause them to become limp.
If your plant is constantly drying out and/or wilting, it may be time to repot it into a slightly larger container. Christmas cacti flower best when they are a little pot confined, but don’t go overboard.
Use a commercially packaged potting mix for succulent plants or make your own by mixing two parts plain potting soil with one part clean sand or vermiculite. Prune your Christmas cactus after it blooms to encourage it to branch out. Remove a few sections of each stem by pinching them off with your fingers or cutting them with a sharp knife. These sections can be rooted in moist vermiculite to propagate new plants.
The formation of the bud on the Christmas cactus is dependent on a specific combination of day length and temperature. In the Northern Hemisphere, these plants will begin the blooming process when the day length is approximately equal to the length of the night and the temperature is in the range of 50 to 60 degrees F. Christmas cactus will bloom if given long uninterrupted dark periods, about 12 hours each night.
What is the real name of the Christmas cactus?
Thanksgiving cactus, holiday cactus, and crab cactus are all names for the Christmas cactus (Schlumbergera truncata). The leaf-shaped stem segments with curled, sharp teeth or claws around the margins are known as crab claws. The leaf segments of the Easter cactus (Schlumbergera buckleyi) have rounded edges. They all originated in the gloomy, damp forests of southeast Brazil. They’re called epiphytes because they thrive on trees above ground, in places where branches meet and decomposing fallen leaves and mosses collect.
Despite the fact that this plant is called a cactus, the care it requires has little to do with its desert cousins. It’s a cactus that grows in the forest. Its requirements can be traced back to their source. The optimum time to plant a Christmas cactus is when it is warm “I’m stuck in a pot.” This entails keeping it in a small container for as long as possible before transferring it to a little larger pot. They prefer a nutrient-dense organic potting mix and should not be allowed to dry out. When the plant is blossoming, increase the amount of water it receives. They enjoy indirect light that is bright. As the plants begin to burn, the leaf segments might turn a dark crimson color.
‘The’ “The “secret” to getting your Christmas cactus to bloom in the years after you buy it boils down to two factors: light and temperature. These two are the keys to the kingdom of flowers. Flowers are produced by Christmas cacti in a chilly, short-day cycle. It takes at least eight days of 16 hours of darkness and 8 hours of light every day to start the creation of flower buds. Do not turn on the lights at night, even if only for a brief time, wherever the plant is put. This violates the required dark cycle. It should be around 61 degrees Fahrenheit. Avoid placing the plant in an area where it will be exposed to cold or hot air drafts.
It’s as simple as putting the Christmas cactus on the window sill in a chilly room and not turning on the lights. If the plant was in a brightly lit room, the side closest to the window often grows buds, but the plant’s illuminated side does not. If the plant produces flower buds but then loses them, it’s usually due to either too much or too little water or a lack of air humidity. The good news is that if their temperature and light needs are met, Christmas cacti are reasonably straightforward to re-bloom.
Why is my Christmas cactus turning red?
A magnesium deficiency, which is a common illness in Christmas cacti, is characterized by red or purple-tinged foliage and wilting. It happens primarily during the winter months, when feeding and watering are restricted and the plant’s nutrient uptake is slowed by freezing temperatures. Winter temperatures of 55 to 65 degrees Fahrenheit are ideal for the cactus. Epsom salts can be used to treat a magnesium deficit. 8 heaping tablespoons Epsom salts dissolved in 2 1/2 gallons water, plus 1 to 2 drops dishwashing liquid Fill a spray bottle halfway with the mixture and spritz the tops and undersides of the foliage. Reapply the mixture every two weeks until the foliage regains its natural color.
Why is Christmas cactus purple?
Repotting Christmas cactus in the spring is recommended if the plant is rootbound. Transfer the plant to a well-drained potting mix, such as ordinary potting soil mixed with perlite or sand. The pot has to be one size bigger.
Christmas cactus requires intense light during the fall and winter months, but too much direct light during the summer months may cause the leaves to become purple on the margins. Sunburn can be avoided and the problem solved by moving the plant to a more suitable place. Make sure the area is distant from drafty windows and open doors. Similarly, stay away from hot, dry regions like around a fireplace or a heating vent.
What is the difference between Easter cactus and Christmas cactus?
The Christmas season has arrived, which means not only holiday decorations but also seasonal plants! This is the time of year when there are a lot of attractive holiday plants to pick from, whether you buy them from a florist or a nursery, or you grow them yourself. The Christmas cactus is one of the most popular plants to give or receive at this time of year. Is it a cactus for Easter or Thanksgiving?
The shape of the leaves is the distinction between the three cacti. On the edges of the leaf of the Thanksgiving cactus (Schlumgera truncata), there are exceedingly sharp and claw-shaped projections. The leaf projections of the Christmas cactus (Schlumgera bridgesti) are more scalloped or tear drop shaped. The Easter cactus (Rhipsalidopsis gaertnerrii) features a leaf with highly rounded margins that are centered.
Why is my Christmas cactus blooming in June?
“What went wrong with my grandmother’s Christmas cactus that is about to bloom? Mary Ann
Hello, Martha. In addition, I have a “I have a “Christmas” cactus flowering right now, and I’m dubbing it my Winter cactus because of the blossoms. In Missouri, these hardy tropical plants require a little assistance to bloom on time. They have meteorological triggers in their native Brazil that cause them to blossom in December, the start of the South American summer.
If it originated from your grandma, your cactus could be an older, authentic Christmas cactus. The majority of cacti on the market now are Thanksgiving cacti, which explains why they bloom around late November.
Look at the green fronds to see what kind of cactus you have. Thanksgiving cacti (Schlumbergera truncata) have pointed, jagged edges, whereas the original Christmas cactus (Schlumbergera bridgesii) has smooth, round edges.
Because I had it outside on my back porch last fall, it began to bloom. Thanksgiving and Christmas cactus are known as “short day plants,” as they require fewer daylight hours and/or cool night temperatures to generate bloom buds. The shorter days and chilly nights of autumn prompt the plants to start producing buds.
Place your Christmas cactus indoors in a cool, bright setting with daily temps of 65-70° F and evening temperatures of 55-65° F to ensure that it blooms when you want it to. Plants will blossom in around 5-6 weeks if they are exposed to colder night temperatures of 55° F, independent of the day length.
Why is my Christmas cactus not blooming?
Drought stress or too much light, as it is a short-day plant, are the causes of Christmas cactus not blooming. The Christmas cactus has evolved to thrive in humid, rainy environments. If it’s too dry or there are too many hours of sunshine during bloom creation, it won’t flower.
There are a number of other reasons that can hinder the Christmas cactus (Schlumbergera) from blossoming, which I’ve included below:
Continue reading to learn why your Christmas cactus isn’t blossoming, as well as the best methods and strategies for getting it to bloom…
How long do Christmas cactus live?
With good cause, the Christmas cactus may be found all over throughout the holiday season. It’s a blooming succulent that’s easy to care for, has beautiful blossoms, and may survive for up to 100 years if properly cared for! That’s correct! This plant can last for decades, giving your holidays a splash of color for generations. That’s a fairly good return on investment for a plant as simple and low-maintenance as the Christmas cactus!
Is Epsom salt good for Christmas cactus?
The winter solstice occurs on December 21, when the Northern Hemisphere experiences the shortest day and longest night of the year.
Christmas cacti, poinsettias, kalanchoes, and chrysanthemums are some of the most popular plants given as holiday gifts because their blossoming is ideally matched to the shorter days encountered this time of year.
The commencement of flower buds in many plants is influenced by the quantity of light they get. “Photoperiodism” refers to a plant’s response to day length. Some plants bloom as the days become shorter, while others bloom as the days get longer. Some plants are agnostic, meaning that the duration of the day has no effect on flowering.
Christmas cactus are popular houseplants from Brazil that come in a variety of colors such as red, rose, purple, lavender, peach, orange, cream, and white. In shaded rain forests, these species grow as epiphytes among tree branches, and their cascading stems make them ideal for hanging baskets. If the plants are managed at 68 degrees Fahrenheit, flowering can last seven to eight weeks.
During this time of year, clients frequently contact the University of Georgia Cooperative Extension office, dismayed that their Christmas cacti or other short-day houseplants have failed to blossom. They are frequently startled to hear that if these plants are kept indoors all year, their natural cycle of daylight exposure can be disrupted by artificial light. As a result, the problem becomes simulating regular daylight exposure on shorter days.
Place these plants in a room with solely natural light exposure near a window, ensuring that artificial lighting is turned off at night. Another alternative is to let these plants outside as long as possible in the fall and then bring them inside right before the first frost. In the Atlanta area, this usually means keeping most tropical houseplants outside until the end of October. Short-day plants have been set to begin flowering during the upcoming holidays around this time.
Every year, my grandfather would keep a Christmas cactus in a hanging basket on his porch throughout the summer and bring it inside just before the first freeze. It was a large shrub with hundreds of flowers that bloomed from Thanksgiving until Christmas. I recall him keeping this plant alive for almost a decade, and it offered him a lot of Christmas delight over the years.
One of the best things about a Christmas cactus is that, unlike poinsettias and other houseplants, it does not shed leaves. Because Christmas cactus lack genuine leaves, photosynthesis takes place within the green stem segments known as phylloclades. Early in June, pinch back the stems to encourage branching terminals for more flowers, and use three to five segmented stem portions to root new plants.
Temperature adjustment and photoperiod (day and night) control are the keys to good flower bud generation on Christmas cacti in the fall. Flower bud set requires fourteen hours or more of continuous darkness each night to occur.
For complete bud set, begin long nights in the middle of September and continue for at least six weeks. Flower bud set can be inhibited by as little as two hours of interrupted lighting. In most cases, buds will appear in four weeks. Once the buds are set, the photoperiod has little effect on flowering.
During the spring and summer, Christmas cacti may survive dry, slightly underwatered circumstances. Allowing the soil to grow saturated is a bad idea, especially during the long winter evenings. To prevent flower buds from dropping off during bud set in the fall, the soil must be kept equally moist. Allow no water to collect in the saucer beneath the pot.
Fertilize plants monthly using a half-strength liquid fertilizer, such as 20-20-20 with trace elements, starting when new growth begins in late winter or early spring and continuing throughout the summer. Christmas cacti have a greater magnesium need than many other plants. Apply Epsom salts (magnesium sulfate) combined at 1 teaspoon per gallon of water once a month throughout the growing season, but not on the same week as regular fertilizer. Fertilize less in the late summer to encourage more flower bud formation in the fall.
Why do buds drop off Christmas cactus?
A: Your new Christmas cactus appears to be reacting to a change in the environment. Overwatering, temperature fluctuations, and a lack of light can all cause buds to drop. Your plant was given careful care to ensure that it bloomed over the Christmas season, as well as ideal growing conditions. It faced less-than-ideal circumstances somewhere in transit, or perhaps in your home. The bud drop that results is the plant’s way of dealing with the stressful circumstances.
