Moisture is also vital for Christmas cactus. During its vigorous growth in the spring and summer, the plant requires frequent and thorough watering to maintain the soil slightly damp. Allow the moisture levels in your Christmas cactus to drop and dry out a little between waterings, but never totally, and never let the plant sit in water, as this will cause root and stem rot. It’s also fine to apply a light houseplant fertilizer solution every other week.
How do you care for a Schlumbergera plant?
Water only when the top 2-3cm of compost is dry in the spring and summer, and let any surplus water drain away Christmas cacti will suffer if they sit in cold, damp compost. During the winter and the two rest periods, use less water.
Schlumbergera is a rainforest plant that thrives in a humid environment. Mist your plant once or twice a week, or place it in a water tray with pebbles. In the spring and summer, feed once a month.
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!
How do I keep my Christmas cactus blooming?
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 care for a Schlumbergera Christmas cactus?
- 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.
Is Schlumbergera an indoor plant?
The Christmas Cactus (Schlumbergera bridgesii) is a popular winter-flowering houseplant that works well in almost any indoor environment. It’s not only easy to care for, but it’s also easy to propagate, making it an excellent choice for holiday gift giving.
How do you propagate Schlumbergera?
The Christmas cactus is a plant that is reasonably simple to grow. Take one to four-segment cuttings and store them in a cool, dry area for two to four days. Plant in new soil, preferably a sand/peat mix, an inch deep. Water sparingly until new growth or roots appear, then water as needed.
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.
How cold can cactus tolerate?
As long as you have enough light, cacti are among of the most rewarding home plants. Few flowers can match them in terms of color, size, or beauty. Because most cacti grow slowly, space is rarely an issue. They are extremely resilient and versatile. They do not, contrary to common opinion, “thrive on neglect.” They “thrive” on gentle loving care, as do most plants, but they will “survive” on neglect.
Christmas cactus, rhipsalis, orchid cacti, and other epiphytic (tree-dwelling) cacti and succulentsChristmas cactus, rhipsalis, orchid cacti, and other speciesprefer less sunshine, greater humidity, and more watering than other species. They also want a higher nitrogen content in their fertilizer. In your potting mix, use less sand than you would for other plants. Haworthias and a few other succulents prefer brilliant indirect light to direct sunlight as well.
Light
Indoors, provide the brightest or sunniest window you can for cacti and other succulents (four to six hours of direct sun). They will grow long and slender under low light, which is an aberrant growth tendency. Summering your plants outdoors in the morning or late afternoon sun can greatly benefit them, as will enhanced air movement and light. Most succulents can withstand direct sunlight, but they must be acclimated to it. Set plants outside in partial shade or shade for the first several weeks before gradually exposing them to the strong late spring and summer sun.
The most sun is required for wooly and strongly spiny species, while spineless species prefer shelter during the daytime hours. A reddish staining may signify that your plant has reached or beyond its maximum solar tolerance.
Watering
When watering, make sure to water thoroughly and then let the soil dry before watering again. Succulents are particularly susceptible to rot as a result of over watering. If the earth is already moist, do not water your plant. Wet pots are heavier than dry pots. When the soil in a clay pot is moist, it feels chilly and damp to the touch. When the plant has enough moisture in the soil, succulent leaves are solid and plump.
During the cooler months of the year, most cacti and other succulents like to be much drier (usually October through April). During this time, you should drink less water than usual. On warm days in the spring, spray your plants early in the morning to encourage new growth. Plants use their spines to absorb moisture. Early in the spring, we also recommend watering plants from the bottom of the pot so that new roots can sprout without being suffocated by moist soil. Fill the plant’s saucer halfway with water, wait 30 minutes for the soil, pot, and plant to absorb it, then drain the excess.
If your plants are in clay pots, embed them in a combination of 50 percent peat and 50 percent coarse builder’s sand to maximize their potential. This keeps the soil from drying out too quickly and helps the roots to grow in the consistent moisture provided by the peat/sand mixture. Make sure the peat/sand mix pan has adequate drainage.
Temperature
Keep cacti and succulents above freezing in the winter. Some plants like a temperature of 35-40oF at night (some cacti and other succulents can endure temperatures well below freezing if kept absolutely dry.) Succulents from the tropics, such as adeniums, euphorbias, lithops, and stapeliads, prefer temperatures of 50-60 degrees.
Plants in pots should be sheltered from high heat in the summer since their root systems are more prone to harm. When it’s humid and hot outside, excellent air circulation and cautious watering will keep fungus and rot at bay.
Fertilizer
From May through September, feed your plants once a month using a low nitrogen (less than 10%) formula fertilizer like 5-10-5 or 10-30-20. Excessive nitrogen causes quick green development but weak growth. Because most cacti have adapted to growing in nutrient-poor soils, always dilute the fertilizer more than the label directions suggest.
Repotting
In the spring or early summer, repot the plants. When young, most species benefit from annual repotting with only one pot size increase. You can remove the top inch or two of soil and replace it with fresh mix without transplanting the plant to a larger pot after you reach about a 6″ pot size. Succulents are heavy plants, especially when potted in clay, and moving them to larger and larger containers becomes challenging.
Avoid soils that contain a lot of peat moss. Peat retains water for far too long and is difficult to moisten once completely dry (a frequent occurrence with most succulents). A tiny amount of peat can be added to the soil to improve texture, and coarse builder’s sand can be added to assist drainage. Lithops (living stones), woolly cactus, and stapeliads all benefit with up to 40% sand. A top dressing of fine gravel around the base of the plant is recommended because it improves water absorption, protects the plant from excessive wetness, and is also aesthetically beautiful. If possible, for every 3 people, add a tablespoon of bone meal and gypsum.
To grip and ease a severely spiky plant out of its pot, use a pair of wooden tongs or a folded up piece of newspaper. If the plant is stubborn, don’t pull it out because you’ll damage the root system. Try again by slamming the pot against a hard surface. As much soil as possible should be removed without causing damage to the root ball. To avoid rot, always repot the plant at or above the previous soil level. It’s possible that you’ll need to stake columnar species. To allow new root hairs to form, wait a week or two after repotting before watering.
Should I water my 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.)
Why are the buds on my Christmas cactus falling off?
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.
