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.
Can Christmas cactus go outside in summer?
A healthy Christmas cactus in full bloom is a terrific present or decoration, even if the poinsettia is still the most popular holiday plant. Christmas cactus is a low-maintenance plant that may be kept indoors all year. The flowers come in a variety of hues, including yellow, salmon, pink, fuchsia, and white, as well as combinations of these colors.
Place a Christmas cactus in a sunny interior spot once it has been moved to its permanent home. The best light comes from a north or east window. If you wish to grow it inside in a south or west window, use thin drapes to shade the plant.
The Christmas cactus is a succulent plant with leaves that can store a significant amount of water. It is not, however, as drought tolerant as you might imagine. When the top half of the growing mix seems dry to the touch, water vigorously. The duration of time between waterings depends on the air temperature, amount of light, growth rate, and relative humidity.
Christmas cactus thrives in humid environments. Place the container on a pebble tray. To improve humidity surrounding the plant, keep water in the tray. Continue to look after the plant in this manner until it has finished blooming.
Allow the plant to rest for six weeks after it has finished blooming. Continue watering to keep the soil moist but allow the surface to dry off. Transfer the plant to a new pot or top-dress with fresh growing mix as tender growth appears in the spring. For Christmas cactus, a well-drained potting mix is essential. Succulent plants should be planted in a professionally prepared potting mix. Repotted plants should be done every two to three years or anytime the container becomes too full of roots. Plants that look to be unhealthy can be repotted at any moment. Every 2 to 3 weeks, administer half the recommended rate of a liquid houseplant fertilizer.
In the summer, you can transfer your Christmas cactus outside, but it should be kept in a partially to fully shaded area. The leaves can be burned by direct sunlight. For the summer, some gardeners relocate their plants to the shade of a porch or patio. Water to keep the growing mix moist after it dries on top throughout the heat.
When September arrives, bring the plant inside after making sure there are no insects accompanying it. Most insects that try to catch a ride are frightened away by a trickle of water. Place the Christmas cactus in a bright spot, just as it was before it went on holiday. Flower development necessitates a high level of light intensity.
Water simply enough to keep the plants from wilting as part of your fall maintenance. Before watering, allow the top half of the potting mix to dry out. Don’t forget the water in the pebble tray for humidity. Unless the plant wilts, do not water it during the month of October. In November, you can begin watering again with caution. Branches droop and break as a result of over irrigation. When the growth mix’s surface dries out, water it.
Christmas cactus is easy to grow, but others say it’s tough to get it to bloom again. Cool temperatures are necessary for flowering, even though high temperatures are beneficial during the growing season. Keep the plant between 60 and 65 degrees Fahrenheit from October onwards. Heat vents, fires, and other sources of hot air should be kept away from Christmas cactus. Flower buds will form as long as the temperature stays in this range for six weeks.
If you can’t manage the temperature in this range, you’ll need to give the plant 13 hours of uninterrupted darkness each night starting around October 1st to promote flowering. Each night, place the Christmas cactus in a fully dark room or cover it with a dark cloth or box.
Stop fertilizing and only water enough to keep the leaves from drooping throughout the flower bud production phase, which begins in October. When the top half of the growing mix becomes dry, water it.
Once the buds have formed, keep the Christmas cactus in medium to high light and at room temperature. Water the plant when the top of the growing mix dries up to maintain it equally moist. Fertilize your Christmas cactus using a half-rate liquid houseplant fertilizer every other week. In the next year, best of luck with your Christmas cactus and all of your indoor and outdoor gardening.
How much sun does a Christmas cactus need?
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.
Can a Christmas cactus handle direct sunlight?
According to Christmas cactus care advice, it thrives in typical household settings with minimal attention. Although the Christmas cactus can adapt to low light, it will produce more blooms if it is exposed to brighter light. However, too much direct sunshine will burn the leaves of the Christmas cactus, so maintain it in a shaded spot to avoid this.
Do you water a Christmas cactus from the top or 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.)
How much heat can a Christmas cactus take?
Holiday cacti are common houseplants that bloom around the holidays, as the name suggests. Christmas cacti bloom throughout the winter and generate a large number of brilliant pink blossoms. They are only hardy in US Department of Agriculture zones 9 to 11 as outdoor plants. When it comes to Christmas cactus, how chilly can it get? Christmas cactus has a higher cold resistance than some other cacti, but they are tropical. They can’t stand frost, but they require the cold to force blossoms.
Christmas cacti prefer warm, balmy temperatures, moderate to low moisture levels, and strong sunlight as a tropical plant. It prefers a warm environment, but keep it away from drafts, heaters, and fireplaces. Temperatures in the evenings should be between 60 and 65 degrees Fahrenheit (15-18 C.).
Place the cactus in a colder area in October, around 50 degrees Fahrenheit, to force it to bloom (10 C.). Avoid rapid temperature changes while the plants are in bloom, as this might cause Christmas cacti to lose their flowers.
In the summer, it’s quite good to move the plant outside, preferably somewhere with dappled light and protection from the wind. You can expect Christmas cactus frost damage if you leave it outside too late in the fall.
Where should I put a Christmas cactus outside?
Plant Christmas cactus in a container or hanging basket if you live in a cool location so you can bring it inside when the weather drops below 50 degrees Fahrenheit (10 C.) Use a potting media that drains effectively, such as a mix of potting soil, perlite, and orchid bark.
In warmer climes, a place in light shade or early morning sun is preferable for growing Christmas cactus outside, however a sunnier site is fine in the fall and winter. Be wary of direct sunlight, since it might bleach the foliage. During the growing season, temperatures between 70 and 80 degrees Fahrenheit (21-27 degrees Celsius) are excellent. Sudden changes in light and temperature, which might cause the buds to drop, should be avoided.
How can you tell if a Christmas cactus is overwatered?
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.
What conditions do Christmas cactus like?
Schlumbergera can be found in jungle-like forests connected to trees in their natural habitat. They prefer a semi-shade environment versus the full light of desert-dwelling cacti. A well-lit, but out of direct sunlight, environment with a humid climate would be excellent. Use gravel-filled saucers to place your plants on and keep them moist to improve humidity.
To sustain healthy growth, repot once a year (or at least every two years). This can be done at the end of March, when their growing season begins. To help with drainage, use a regular cactus compost or a loam-based compost like John Innes No 2 with additional leafmould (or peat substitute) and grit. Choose only a slightly larger container for potting on, as they prefer to be tight in a compact pot.
Aftercare
- A period of rest is required after flowering. Restrict the temperature to 12-15°C (55-59°F) and reduce the watering to only once or twice a week from late January to late March to avoid the compost drying up altogether. Moving to a cooler environment is a simple way to accomplish this.
- Increase the watering and start feeding with a houseplant liquid feed during the growing season, which runs from April to September. Maintain a temperature of 18-20°C (65-69°F) during the growing season if possible.
- They can be placed outside throughout the summer months, once the risk of frost has passed. This promotes flowering and helps to ripen new growth. Keep them in a shady area away from snails.
- With the shorter days and cooler temperatures, flowering buds begin to form around mid-September. With a second resting period, the watering and temperature should be reduced (as before). Increase the temperature to 18-20°C (65-69°F) and begin regular watering just until the flowering buds have formed.
- After that, your plant should bloom and provide you with a stunning display. If there are two resting periods with a reduction in watering and temperature, exact temperatures are not required to encourage flowering.
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 cacti are the earliest and most persistent bloomers, blooming from late fall 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!
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.
