Christmas cacti generate beautiful flowers and trailing jointed stalks. These epiphytes, which are native to Brazil, are ideal houseplants. The majority of the time, cacti require little maintenance and flourish in conditions of average hydration, indirect, bright light, and well-draining soil. Monthly feedings of Christmas cacti are done during the growing season, which is typically from April to October. This will maintain your plants healthy so that they can develop buds and eventually have that completely blossomed appearance in time for Christmas.
You don’t have to fertilize your gift of cacti if you don’t want to maintain it. The plant will gradually starve to death as the soil eventually releases all of its nutrients. Any lazy cactus will liven up with fresh soil and the addition of houseplant food, but timing is crucial.
In the autumn, when the weather is cooler and the days are shorter, Christmas cacti form buds. In order to deceive the plant into producing buds, they require 12 hours of darkness. Christmas cactus may develop strong growth to maintain the blossoms if fertilized in the spring and summer. Additionally, the plant stores energy to support the development of buds. When fall hits, the plant is forced to produce magnificent hot pink to red blossoms by a harsh schedule of shorter days, cooler temperatures, less water, and no additional nourishment.
When exactly do I need to feed my Christmas cactus?
Beginning when you notice fresh growth at the end of winter or the beginnings of spring, fertilize the plant once a month after it has finished blooming. Give a 20-20-20 or 10-10-10 plant food diluted in water to 50% strength when feeding a Christmas cactus.
How frequently should you fertilize Christmas cactus?
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.
Does Miracle Gro work well with Christmas cacti?
When Christmas cacti are tightly contained in their containers, they typically grow bigger and produce more flowers. But once the roots have nearly filled the pot, proceed as follows:
1. Choose a replacement pot with a drainage hole that is only 1 to 2 inches wider than the old one.
2. To help your Christmas cactus thrive straight away, fill the new container 1/3 full with Miracle-Gro Cactus, Palm & Citrus Potting Mix, which offers great drainage and a little amount of food.
3. After placing the plant in the pot, make sure the root ball’s top is positioned 3/4 to 1 inch or less below the pot’s rim.
4. Fill in the area around the rootball, leaving a gap of about 3/4 inch between the soil’s top and the container’s lip (for easy watering).
5. After giving the plant plenty of water, let it drain, then relocate it to a permanent location. (Place a water-resistant saucer underneath the pot to prevent spills on the furniture.)
Secret tip: After plants have recovered from blooming and begun to grow again in late spring, this is the ideal time to repot them.
Size
Christmas cacti are typically marketed in sets of four or six pots. Additionally, I’ve seen them in hanging baskets that are 6, 8, and 10.
I once saw one in a greenhouse in Connecticut that had a quite large, weeping form. It was wider than six. They can live for a long time indoors, yes!
Light
Bright, natural light with a medium to high light exposure is what they prefer and perform best in. Because their fleshy leaves will burn in the sun and on hot windows, make careful to keep them away from these areas.
Although they don’t thrive in direct sunlight, they do require bright light to grow, bloom, and maintain their attractiveness all year long.
My own grows alongside a large number of other houseplants on the lower shelf of a long table in my dining room. It receives intense but filtered light from three south-facing windows that are around 7 away from it.
Water
The desert cacti I’m surrounded by here in Tucson are different from these epiphytic cacti. Schlumbergeras grow on other plants and rocks, not in the soil, in their native rainforest habitat.
This implies that their roots require airflow. They won’t survive long if you keep them consistently damp; root rot will eventually kill them.
Give yours a good sip and then completely allow all the extra water drain out of the drainage holes in the pot’s bottom. Before watering it once again, let the potting mix dry out.
The temperature of your home, the exposure it receives, the type and size of the pot it is in, and the soil mix it is placed in will all affect how frequently you water your Christmas cactus.
Every 2-3 weeks in the summer and every 3-5 weeks in the winter, I water the plants I have growing in an 8-pot.
Water your Holiday Cactus a little more frequently when it is blooming. Reduce watering in the winter after it has flowered. If necessary, you can increase the frequency of watering in the spring and summer.
My Santa Barbara garden’s terra cotta potted Christmas cacti were grown outside. In moderate climes, they do really grow outdoors year round. In the summer, I watered them once a week, and in the winter, depending on whether it rained or not, I occasionally neglected to water them at all.
Should you fertilize a blossoming cactus?
This aids in the plant’s replenishment of the soil’s nutrients, which it had been using all season.
Cacti do indeed need fertilizer. The appropriate fertilizer applied in the right amounts and at the right times promotes plant growth.
fertilizing plants while they are actively growing to promote strong development, vivid color, and blossoming in species that are able to do so.
What causes the blooming of a 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, pointy teeth or claws around the margins are known as crabs. The leaf segments of the Easter cactus (Schlumbergera buckleyi) have rounded edges. They all came from wet, dark forests around the southeast coast of Brazil. Because they reside above ground in trees, where branches meet and decaying leaves and moss amass, they are categorized as epiphytes.
Although this plant has the moniker “cactus,” the maintenance it needs has nothing to do with its relatives in the desert. It is regarded as a type of woodland cactus. Its needs can be traced back to its beginnings. It is recommended for Christmas cactus to grow in “Potty trained That entails storing it in a small container for as long as possible before transferring it to a pot that is only marginally larger. They should not be allowed to dry out and like a thick organic potting mix. When the plant is blossoming, increase the watering. They favor direct, bright light. As the plants start to burn in full light, the leaf segments might turn a dark red color.
The “The two factors of light and temperature are the key to getting Christmas cacti to bloom in the years after purchase. These two hold the secret to the realm of flowers. Flowers are produced by Christmas cacti during a chilly, brief day cycle. It takes at least eight days of 16 hours of darkness and 8 hours of light every day for flower buds to begin to form. No matter where the plant is located, avoid using the lights at night, even for a little time. That ends the necessary dark cycle. Around 61 degrees should be the ambient temperature. Place the plant away from drafts of either cold or hot air.
All that is required is to set the Christmas cactus on the window sill in a chilly area without turning on the lights. In a brightly lit space, a plant’s side towards the window will frequently sprout buds, but not the other way around. It usually has to do with either receiving too much or not enough water or with there being insufficient humidity in the air if the plant sets flower buds and then they fall off. The good news is that if their temperature and light needs are met, Christmas cacti are thought to be rather simple to induce to bloom once more.
Should my Christmas cactus be misted?
Contrary to what its name might imply, Christmas cacti can survive well into the following year. In fact, with a little care and our guidance, they can live for up to 20 years.
Christmas Cacti need cooler temperatures.
Leaving Christmas cacti in a space that is between 60 and 70 degrees Fahrenheit will cause them to bloom more fully and sooner. Keep them away from radiators, fireplaces, and warm windowsills, especially during the winter.
While they don’t need the heat of the sun, they do need its light.
The hard part comes at this point. A Christmas cactus needs lots of sunlight but cannot be kept in direct sunlight as it will dry out. So what should a cactus aficionado do? Your best option is to leave it in a part of your home that is shaded (or outdoors once summer arrives) and rotate it occasionally.
Just like you and I, Christmas cacti need their rest.
Your cactus needs between 1215 hours of uninterrupted darkness per day if its buds haven’t yet set. Cacti only require lots of light once their buds have fully developed.
You should be misting, not watering, every day.
Your cactus will die if you overwater it. But that doesn’t mean they never experience thirst. You should mist your cactus every day rather than watering it like you would a regular plant. You only need a few sprays from a spray bottle to maintain your cactus’ happiness. Only when the soil at the base of the plant feels entirely dry to the touch should you water it.
Christmas cacti need nutrient-rich soil.
Christmas cacti are strong plants that can endure harsher environments, although well-drained soil that has some organic matter is preferable for them. While organic soil is always available to purchase, you can also use your cacti as a little compost and add organic waste that you would typically discard.
