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.
How do you take care of a Christmas cactus indoors?
- Watering: Mist your plant frequently while it is blooming to keep the soil uniformly moist.
- Light: For moderate light and some direct sun, place the cactus in an east-facing window.
- Fertilize every two weeks once buds have formed with a high-potassium fertilizer.
How often do you water a Christmas cactus?
- Water every two to three weeks, but only until the top one-third of the soil feels dry to the touch. Water when the top 2 inches of soil feel dry, for example, if the plant is in 6 inches of soil. (Check with your finger!)
- Soak the soil until water runs through the drainage holes in the pot when it is suitably dry. To catch the water, place a tray underneath the pot. Remove any extra water from the tray after 10-15 minutes so that the pot does not sit in water.
- Feed every two weeks with a balanced houseplant fertilizer from spring through early fall. Feed the cactus once a month in the fall and winter to encourage blooming.
- Late in the spring, prune plants to encourage branching and more flowers. Simply cut a few portions off each stem, and the plant will branch out from the wound.
- Place the cut pieces in a gently wet potting soil if desired; they will root easily after a few weeks and make great Christmas gifts!
How to Get Your Christmas Cactus to Bloom
The lower temperatures and longer evenings of autumn bring out the blooms of Christmas cacti and its relatives. This is the general blooming schedule for the three main species of Christmas cacti:
- Thanksgiving cactus are the earliest and most persistent bloomers, blooming from late October to mid-winter.
It’s possible that your cactus isn’t flowering because it’s getting too much sunshine or being exposed to too hot temperatures. Here are some pointers to help you get yours to bloom!
- For at least six weeks, nights must be at least 14 hours long and days must be between 8 and 10 hours. If you have powerful interior lighting that is turned on at night, you may need to cover your cactus or transfer it to a location where it can be exposed to natural light.
- Flower buds form best when the plant is kept between 50 and 60 degrees Fahrenheit (10 and 15 degrees Celsius).
- By exposing the plant to temperatures of around 45°F (7°C) for several nights in a row, you can jumpstart the budding process.
- Ensure that you water the plant on a regular basis when it is in bloom. If the plant dries out too much, the buds may fall off.
- Don’t worry if the cactus loses its buds throughout the winter; it will bloom the next year!
Where should I put my Christmas cactus?
Throughout the winter and spring, holiday cactus are extremely popular gifts, and they can be found in just about any store that sells plants, from the grocery store to the flower shop. Holiday cactus are eye-catching with their succulent leaves and vivid blossoms in a variety of colors, and they find their way into the homes of both expert and novice houseplant aficionados. They can live for decades if properly cared for, and are frequently passed down from generation to generation.
Christmas cactus (Schlumbergera x buckleyi), Thanksgiving cactus (Schlumbergera truncata), and Easter cactus (Rhipsalidopsis gaertneri) are three distinct types that are typically available at retail stores depending on the season “The term “Christmas cactus” is frequently used to refer to all of them. It’s easier to refer to all three as holiday cacti for the sake of convenience, given they require fairly comparable care.
Regardless, “Despite the fact that “cactus” is in their name, holiday cacti require very different care than their desert-dwelling siblings. Holiday cactus are epiphytes that grow on the shady limbs of trees in the tropical rainforests of Brazil. Epiphytes are plants that grow atop other plants rather than in the soil, relying on the air and rain for moisture and nutrients.
As a result, unlike other cacti, holiday cacti do not endure prolonged dehydration. Once the potting soil is dry to the touch, they should be watered, allowing excess water to drain freely from the bottom of the container. Allowing plants to sit in standing water will cause the soil to become soggy. Root rot can be caused by prolonged exposure to damp soil, especially during the winter months.
Watering holiday cacti is dependent on a variety of parameters, including the type of potting soil used, the size of the container, the amount of sunlight the plant receives, and the ambient temperature. The key to sustaining a healthy plant is to make sure it’s in the appropriate spot and to only water when the soil mix is completely dry.
Holiday cacti thrive in partial shade, such as an east or west facing window, and at temperatures between 70 and 80 degrees Fahrenheit. Too much strong sunshine, especially during the summer months, can burn the foliage, while insufficient light can stifle growth and cause the soil mix to dry up too slowly. When in doubt, go with the under-watering method rather than the over-watering method.
Is Christmas cactus a low light plant?
Christmas cacti require strong, indirect light to thrive. If you’re going to put one indoors near a west or south-facing window, make sure it’s filtered with a sheer curtain. They prefer humidity, so put it on a tray of pebbles or near other plants if your house is dry indoors in the winter.
Never let them sit in water if the top surface appears to be dry.
Christmas cacti prefer temperatures of 65 to 70 degrees during the day and 55 to 65 degrees at night.
Should I mist my Christmas cactus?
Christmas cacti, contrary to popular belief, may live much beyond the month of December. With a little TLC and some advise from us, they can live for up to 20 years.
Christmas Cacti need cooler temperatures.
If you keep your Christmas cacti in a room that’s between 60 and 70 degrees Fahrenheit, they’ll bloom more and faster. It’s especially vital to keep them away from radiators, fires, and warm windowsills in the winter.
While they don’t need the heat of the sun, they do need its light.
This is when things get a little complicated. The sun will dry up a Christmas cactus if it is left in direct sunlight, although it does require lots of sunlight. So, what should a cactus aficionado do? Leave it in a somewhat shaded location of your house (or outside once summer arrives) and rotate it every now and then.
Just like you and I, Christmas cacti need their rest.
If the buds on your cactus haven’t set yet, it will require 1215 hours of complete darkness per day. Cacti flourish in bright light only once their buds have set.
You should be misting, not watering, every day.
Your cactus will die if it is overwatered. That isn’t to suggest they don’t become thirsty. You should mist your cactus every day instead of watering it like you would a typical plant. All you need is a few squirts from a spray bottle to keep your cactus happy. Watering the plant’s base should only be done when the soil is absolutely dry to the touch.
Christmas cacti need nutrient-rich soil.
Christmas cactus are resilient plants that may thrive in a variety of soils, but they need well-drained, somewhat organic matter-rich soil. While you can always buy organic soil, you may also use your cacti as a little compost and add organic materials that would otherwise be discarded.
When should you put a Christmas cactus in the dark?
Place the mature plant in a dark room or keep it covered (under a box or bag works good) for at least 12 hours a day in late September or early October.
What does an Underwatered Christmas cactus look like?
The health of any cactus that has been let to sit in a saucer full of water is likely to suffer. A Christmas cactus plant that has been overwatered will display evident indications of discomfort. If the saucer hasn’t dried in one day, dump the extra water to avoid moisture gnats and root damage.
If you don’t remember to water your Christmas cactus, one of the first signs of overwatering is limp leaves that begin to fall off. The stems and branches will soften and become mushy as a result. In severe situations, the stem will rot entirely off and emit a horrible stench.
It’s easy to avoid. To avoid over-watering your Christmas cactus, use a soil meter.
Do you water a Christmas cactus from the top or the bottom?
Remember that Christmas cactus plants demand moist soil rather than the dry dirt preferred by most other succulents. When the top inch or two of soil on a Christmas cactus is dry, water it. Fill the pot saucer with stones and water to just below the tops of the pebbles (the pot should not be sitting directly in water) to assist improve the humidity around your plant. As the water evaporates, the air will become more humid. (See below for watering suggestions if you’re attempting to get your Christmas cactus to rebloom.)
Why are the leaves on my Christmas cactus limp?
A lack of water or too much direct sunlight can create wilted or limp Christmas cactus. If you haven’t watered the wilting Christmas cactus, start by giving it a small sip. Continue to water gently every several days until the soil is wet but not saturated.
Christmas cactus troubles are sometimes caused by damp soil. Because the Christmas cactus is an epiphyte that takes water and nutrients from the air in its natural habitat on the tropical forest floor, it cannot tolerate damp roots. Christmas cactus can become very limp because to poor drainage and damp roots.
If the leaves on your wilted or limp Christmas cactus appear to be dried or burnt, move it to a more shady location, especially in the afternoon.
Are coffee grounds good for Christmas cactus?
Your Christmas cactus will appreciate a cup of coffee just as much as you! Coffee grounds are high in potassium and nitrogen, which the cactus requires to stay healthy. You should not use the grounds right away since damp grounds can mold, so spread them out to dry first.
