Christmas cacti are highly common indoor plants, and for good reason too! They produce vibrant, tubular flowers that are pink or purple in hue when they bloom. They are a superb plant because of their lovely blossoms, lengthy bloom period, and simple maintenance needs. Someone in your family most likely owns a Christmas cactus!
About Christmas Cacti
The Christmas cactus (Schlumbergera x buckleyi) and its cousins don’t exist in hot, arid conditions like deserts or plains, in contrast to other cacti. These epiphytic succulents, which grow on tree branches and take in the high humidity, dappled sunlight, and moderate temperatures, are actually endemic to the tropical rainforests of southern Brazil.
Bottom line: Don’t handle a Christmas cactus like a typical succulent or cactus. They are unable to withstand the same kind of hot, dry weather that other cactus can. These cacti require more frequent watering than most succulents, but you also need to be careful not to overwater them. (See the care guidelines in more detail below.)
Thanksgiving, Easter, or Christmas Cactus?
The Easter cactus (S. gaertneri), Thanksgiving cactus (S. truncata), and Christmas cactus are the three main varieties of “holiday cacti” that are available (S. x buckleyi). The holiday that each cactus is named after often sees the most blooming. Thanksgiving cacti, which often bloom from November to February and hence go unrecognized as Christmas cacti, make up the majority of “Christmas cacti” sold nowadays. See our post on the several Christmas cacti species and how to distinguish them for more information.
Note: Because it’s the most widely used term and it applies to all three of these species, we’ll refer to all three of them on this page as “Christmas cactus” for simplicity’s sake.
Potting Christmas Cacti
- Choose a pot with a drainage hole on the bottom if you’re choosing one for a Christmas cactus. This prevents the soil from getting overly saturated.
- Most succulent-specific potting mixtures work well for Christmas cacti growth. It’s crucial that your potting soil drains properly.
Where to Put a Christmas Cactus
- Plants should be kept in indirect light that is bright. The best location has an east-facing window or a well-lit bathroom. The delicate leaves might be bleached by too much direct sunshine.
- It is preferable to have a daytime temperature of 70F (21C) and an evening temperature of 60–65F (15–18C).
- Christmas cacti do well in a more humid climate, so keeping them in a well-lit bathroom or kitchen is a smart idea.
- Christmas cacti can be kept in a shady area of the garden or on an unheated porch during the summer until the temperature drops below 50F. (10C). Keep them away from the sun’s rays outside.
How to Care for Christmas Cacti
- Water your plants every two to three weeks, but only when the top third of the soil feels dry to the touch. If the plant is in 6 inches of soil, for instance, water when the top 2 inches of soil feel dry. (Check with your finger!)
- When the soil is completely dry, wet it until water seeps through the drainage holes in the pot. To collect the water, put a tray underneath the pot. To prevent the pot from sitting in water, remove any extra water on the tray after 10 to 15 minutes.
- While the plant is in bloom, it’s very crucial to water thoroughly.
- Feed your indoor plants with a balanced houseplant fertilizer every two weeks from spring through early fall. Feed the cactus once a month in the fall and winter to promote fruitful blooming.
- To promote branching and more flowers, prune plants in the late spring. Simply cut a portion of each stem off; the plant will grow new branches from the incision.
- If desired, plant the cut pieces in potting soil that is only gently damp; they will easily root after a few weeks and make wonderful Christmas gifts!
How to Get Your Christmas Cactus to Bloom
The longer evenings and chilly weather of fall are what cause Christmas cacti and its relatives to bloom. The three major varieties of holiday cacti typically bloom on the following schedule:
- Thanksgiving cactus typically produce flowers from late October through mid-winter, making them the earliest and longest bloomers.
- Christmas cacti often bloom in the early to midwinter months.
- Easter cacti flower around the middle of spring through late winter.
If your cactus isn’t flowering, it can be getting too much light or being exposed to too much heat. Here are some suggestions to help you get blooms from yours!
- For a minimum of six weeks, the nights must be at least 14 hours long and the days between 8 and 10 hours. You might need to cover your cactus or relocate it to an area that is exposed to the natural light cycle if you have powerful interior lighting that is on at night.
- When the plant is kept at temps between 50 and 60F, flower buds form best (10 and 15C).
- By subjecting the plant to temps around 45F (7C) for a number of nights in a succession, you can jumpstart the budding process.
- While the plant is in bloom, be sure to water it consistently. The plant may lose its buds if it dries out too much.
- Don’t worry if the cactus loses its buds one winter; the following year it should bloom.
The three primary varieties of “holiday cacti” are as follows:
- Often mistaken for Christmas cacti, Thanksgiving cacti (Schlumbergera truncata) bloom from late October to mid-winter.
- Christmas cacti (S. x buckleyi) flower in the early to midwinter months.
- Late winter to mid-spring is the blooming period for Easter cacti (S. gaertneri).
- Make sure to water your Christmas cactus frequently and keep it cool when the buds on the plant appear ready to open.
- The optimum time to propagate cuttings is late spring when most holiday cacti start to grow after their winter hibernation.
Blossom loss: Your Christmas cactus will probably lose its blossoms if it experiences any kind of stress. As mentioned in the plant care section above, this could be caused by the amount of light or a sudden shift in temperature. Make sure your soil doesn’t become overly dry while buds are developing.
The plant could be vulnerable to mealy bugs and root rot if overwatered. If you experience issues, remove the affected sections and repot the plant in fresh soil.
When a Christmas cactus is blooming, should you water it?
Maintain a comfortable temperature of 65 degrees. Watering: Mist your plant frequently when it is in bloom to keep the soil equally moist.
Should I water a cactus that is in bloom?
Water is necessary for active growth, including blooms. The majority of cacti in their natural habitat get most of their water each year during the monsoon season. Never water a cactus when it is raining or set it up for automated irrigation. Only water your cactus when necessary to keep it appearing landscape-worthy due to a lack of natural rainfall. Always consider the forecast, humidity, and temperature. By hand, inspect the soil, and be extra careful. Dry the soil entirely in between waterings. This prevents the fungal infections and root, crown, and crown rot brought on by inadequate water management.
When should Christmas cactus be watered?
Remember that Christmas cactus plants prefer constantly moister soil than the majority of other succulents do. Typically, a Christmas cactus needs water when the top inch or two of soil are dry. Fill the pot saucer with pebbles and add water to just below the tops of the pebbles (the pot shouldn’t be sitting directly in water) to help improve the humidity surrounding the plant. As the water evaporation increases, the air will become more humid. (See below for advice on watering when attempting to encourage your Christmas cactus to rebloom.)
When it blooms, should I fertilize my Christmas cactus?
Make sure you have a decent location for the plant to grow because, to begin with, the plants do best in indirect sunshine and well-drained soil. The Christmas cactus has a feeding and growing season that coincide. This indicates that it will require feeding just before it blooms, which should occur between April and October of the current year. Just in time for Christmas, with the right fertilizer and a regular feeding schedule, you ought to have vibrant blossoms.
These plants will bloom during the shorter, cooler days of the fall since they require 12 hours of light and 12 hours of darkness to develop. For the greatest results when fertilizing this plant, choose a bloom formula or a water-soluble formula. To assist the flowers blossom more beautifully in the middle to late summer, fertilize once a month with a high-phosphorus fertilizer.
It’s crucial to make sure you cease feeding the plant after it stops growing, which will happen late in the summer. The salt can accumulate in the bud and prevent it from flowering if you keep feeding the plant even when it is not actively growing. Never fertilize a Christmas cactus when it starts to bloom since this could make the buds fall off.
A Christmas cactus can survive without water for how long?
The Christmas Cactus (Schlumbergera) is a kind of cactus that thrives in Brazil’s chilly, mountainous woodlands where the humidity is high and rainfall is not infrequent.
In sharp contrast, most cacti want dry, arid, sunny environments in order to grow.
Because Christmas cacti are more suited to cool, damp settings than their desert-dwelling brethren, underwatering is one of the most common issues with growing them.
You must mimic some of the humidity and watering requirements of the Christmas cactus’ natural habitat in order to effectively grow it indoors.
Compared to other indoor plants, Christmas cactus needs a higher humidity level. Twice a week or more, spritz some water on the leaves. Throughout the entire year, give the cactus a weekly soak in water.
In order to prevent issues with bothersome overwatering and underwatering, this frequency of watering in conjunction with the appropriate well-draining potting soil helps to replicate the balance of moisture to which it is accustomed.
For the most of the week, the soil should feel evenly moist, with a tiny surface evaporation before the subsequent watering.
A Christmas cactus may withstand two weeks without watering if it is not in an air current or if the air is not too dry. It is also a little more drought tolerant than other houseplants.
It should be noted that a number of variables can affect how quickly or slowly your Christmas cactus dries out indoors, including:
- Your home’s humidity and temperature (houses are often low in humidity which is contrary to Christmas cactus preference for high humidity).
- The pot or container’s size (smaller pots dry out quickly).
- Whether the cactus is close to a heat source, in an air conditioning current, or in forced air (which saps moisture from the leaves and dries the soil).
- The soil’s ability to hold onto moisture (Christmas cactus require moist yet well draining soil).
It is crucial to wet your Christmas cactus to create a microclimate of enhanced humidity to combat the effects of dry air if you live in an area with low humidity or if the air conditioning is frequently running.
Homes tend to be on the dry side, so I advise misting at least once a week regardless of climate, but in arid areas, mist the cacti twice or three times a week.
Keep in mind that Christmas cacti prefer diffused light to direct sunlight. The cactus would lose too much moisture if the sun was too strong and the leaves were burned.
How to Tell if the Christmas Cactus is Over watered or Under watered…
The only way to tell the difference between overwatering and underwatering is to feel the soil because the cactus might wilt and droop in reaction to either situation.
If you can feel the soil at the base of the pot via the drainage hole and it is dry both above and below, the cactus is being underwatered.
If your soil is rapidly drying out, increase the frequency of your watering over the period of 7 days so that the soil is continuously moist rather than dry.
To raise the humidity and lessen water loss via the leaves, mist the under-watered cactus more frequently.
Check to see if there is anything obstructing the drainage hole and remove any water that may be on a tray or saucer used underneath the pot if the soil feels wet or even saturated.
Scaling back watering and making sure the soil drains well may prevent the cactus from developing and flowering properly and may even result in root rot.
What should I do with a blooming Christmas cactus?
Christmas is typically not a time when desert-dwelling flora are highlighted because the holiday generally honors brisk pine tree forests, chilly temperatures, and snowfall. The Christmas Cactus is an exception, though, as it is indigenous to Brazil’s rainforests. It’s difficult to miss this plant during the season with its long flat stems and beautifully colored flowers. The Christmas Cactus will offer you tons of flowers in pinks, reds, purples, and white while it’s tough to get your other cactus to bloom. Possibly not always the colors of the season, but nonetheless lovely.
Perhaps you saw one at the florist or your neighbor decided to give you a Christmas Cactus as a gift in appreciation for your assistance in setting up the lights (well done!). You’re unsure of what to do with it as it sits in your living room, however it got there. You could be a little confused by the fact that it’s a cactus because they are frequently associated with moodiness around water. But unlike its relatives, this cactus is not terrified of water and has very few sharp parts, so it won’t bite. Discover how to take care of your Christmas cactus by reading on.
No life jacket requiredWatering your Christmas Cactus
The Christmas Cactus adores the water, contrary to what you might be used to (swimming, water polo, and perhaps even a little skinny dipping!) It prefers to have regular waterings that thoroughly wet the soil. Although you should allow the soil to dry out a bit between your scheduled waterings, never let it dry out completely. This may impede the growth of your plant and lead it to lose all of the carefully tended flowers!
Warm hugsDon’t give your cacti the cold shoulder
The ideal temperature range for your Christmas Cactus should be between 15 and 21 degrees Celsius, despite the fact that hugging cacti is generally not advised. Like any warm-blooded plant, try to keep it away from drafts and vents. For these guys, a constant temperature is optimal. Although bright light is preferred, excessive amounts of direct sunlight can burn the stems.
A life after ChristmasWhat to do with your Christmas Cactus after the season
Deadhead all the wasted blooms to keep your cacti looking their best during and after the Christmas season. Additionally, this stimulates the plant to keep on blooming. You can continue to enjoy your cacti after Christmas until it eventually stops blooming. But once it does, don’t get rid of it! Whether or not they bloom, these cacti make stunning houseplants. And chances are it will blossom for you once more the next year, and occasionally even in the midst of the year. (Bonus!)
You can prune it at the start of the summer by cutting back a few of the stems’ lankier portions. Similar to getting a haircut, this fosters further growth and allows it to blossom once more.
Whether or not it is the holiday season, your Christmas Cactus will stand out from the rest of your houseplants thanks to its tall stalks and vivid blossoms! Enjoy its distinctive design in your house.
