The Christmas Cactus (Schlumbergera) is a cactus that thrives in Brazil’s chilly, mountainous forests in shaded locations with high humidity and regular rains.
Most cacti, on the other hand, prefer to grow in dry, arid, sunny environments.
Because they are accustomed to cool, humid circumstances, unlike their desert siblings, one of the most common challenges with growing Christmas cactus is not watering them enough.
To grow Christmas cactus successfully in your house, you’ll need to mimic some of the native habitat’s watering and humidity requirements.
The Christmas cactus necessitates a higher level of humidity than most houseplants. Once or twice a week, mist the leaves with a spray. Throughout the year, give the cactus a good bath in water once a week.
This watering frequency, combined with the correct well-draining potting soil, helps to simulate the moisture balance to which it is accustomed, avoiding overwatering and underwatering issues.
For the majority of the week, the soil should feel evenly moist, drying slightly on the surface before the next watering.
Christmas cactus are also more drought tolerant than most houseplants, and may last up to two weeks without watering if not in direct sunlight or if the air isn’t too dry.
There are various reasons that can cause your Christmas cactus to dry out faster or slower in your house, including:
- Your home’s humidity and temperature (houses are often low in humidity which is contrary to Christmas cactus preference for high humidity).
- Whether the cactus is near a heat source or in an air conditioning or forced air current (which saps moisture from the leaves and dries the soil).
- The soil’s ability to retain moisture (Christmas cactus require moist yet well draining soil).
If you live in a low-humidity environment or if the air conditioner is frequently turned on, water your Christmas cactus to create a microclimate of enhanced humidity to offset the effects of dry air.
I recommend sprinkling the cactus at least once a week, regardless of environment, because homes are typically dry, but in dry areas, mist the cactus twice or three times a week.
Keep in mind that Christmas cactus likes indirect light over direct sunlight. The leaves would be burned by too much sun, and the cactus would lose too much moisture.
How to Tell if the Christmas Cactus is Over watered or Under watered…
Because the cactus can shrink and droop as a result of both over and under watering, the only method to tell which is which is to feel the soil.
The cactus is suffering from underwatering if it is dry both on the surface and at the base of the container (feel the dirt at the base through the drainage hole).
If your soil is drying out quickly, increase the frequency of your watering over the period of 7 days to keep the soil moist rather than dry.
To enhance humidity and prevent water loss via the leaves, mist the under-watered cactus more frequently.
If the soil seems damp or even saturated, make sure the drainage hole is clear and remove any water that may have collected on a tray or saucer underneath the pot.
Overwatering or soggy soil can prevent the cactus from developing and blooming properly, as well as create root rot, so cut back on the watering and make sure the soil drains well.
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!
Can you revive a dried out Christmas cactus?
Repot the Christmas cactus into fresh soil when it is extremely limp and the soil is moist. Remove the wilting Christmas cactus from its pot and gently scrape away as much soil as you can. Repotting may be the answer to reviving a wilting Christmas cactus, even if the soil isn’t wet.
Can a Christmas cactus go a month without water?
Overwatering is a problem for Christmas cactus as well as other cactus species. Overwatering can induce fungal rot illnesses like white rot, as well as leaf drop. The white patches on the leaves of white rot disease are immediately identifiable. Because the Christmas cactus is a tropical cactus rather than a desert cactus, it cannot withstand as much under-watering as other cactus species. When a Christmas cactus isn’t given enough water, it wilts and loses its flower buds. A Christmas cactus, unlike a desert cactus, cannot endure completely dry soil. Avoid overhead watering to avoid fungus problems.
How long can a cactus last without water?
Its stems are thick, with plenty of space for water storage and a protective coating to keep the water within. Some cactus species may survive without water for up to two years. Indoor versions, on the other hand, may necessitate more frequent watering, depending on the species.
How long do Christmas cactus live?
With good cause, the Christmas cactus may be found all over throughout the holiday season. It’s a blooming succulent that’s easy to care for, has beautiful blossoms, and may survive for up to 100 years if properly cared for! That’s correct! This plant can last for decades, giving your holidays a splash of color for generations. That’s a fairly good return on investment for a plant as simple and low-maintenance as the Christmas cactus!
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.
How do I know if my Christmas cactus is dying?
A wilted, limp, drooping Christmas cactus with root rot will show wilted, limp, sagging growth, but an examination of the roots will reveal the truth.
Remove the plant from its pot with care. The roots of a rot-affected cactus will be dark at the tips. The decaying Christmas cactus roots will be sticky with black or brown decomposition, depending on the severity of the disease.
If you see that your Christmas cactus is rotting, you must act quickly. Rot is a fatal disease, and the only way to save the plant once it has progressed is to discard it and start over. You can generate a new plant using a leaf from a healthy area of the plant.
How do you take care of a dying Christmas cactus?
When considering the Christmas cactus’ preferences, it’s important to remember that these plants aren’t “cactus” in the traditional sense. They aren’t natural to deserts that are dry, sunny, and sandy. Instead, they can be found growing wild in jungles, where they grow on tree branches rather than on the ground.
- Soil that is light and drains quickly. To increase drainage, incorporate coarse sand or perlite into standard houseplant potting soil. After the plant has finished flowering, repot it every year. This prevents the dirt from compacting around the roots and suffocating them. Remember that the roots of this plant thrive in debris that accumulates in the crooks of tree branches in nature, which is very fast draining and airy.
- When the plant is growing or blossoming, the soil should be continually moist, with a dry period after flowering. Keep the plant in a cooler place for 8 weeks after it has finished blooming and simply water it sparingly to enable it to rest.
- Mist the air around the plant and/or place the pot on or near a dish of damp aquarium gravel to improve humidity.
Limpness is a symptom of root rot, which can develop if the soil remains moist and soggy. However, I believe your plant is simply displaying the effects of its advanced age. It’s possible that propagating a new plant from it is your best option. Simply cut a healthy-looking stem from the plant and place it in damp potting soil. It will most certainly have established roots in a few weeks. (Tug on it to see what I mean.) This new plant will grow more quickly, and you’ll be glad to have it on hand in case the old one fades further.
Does a Christmas cactus need sun?
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.
What happens if you don’t water a cactus?
Cacti and succulents are becoming increasingly popular as houseplants, and proper care is essential. They come in a wide range of forms and sizes, from small to large. Cacti and succulents are related because they both have traits that allow them to thrive in arid climates.
The desert is the natural habitat of most cacti and succulents. As a result, they thrive in bright sunshine, good drainage, hot temperatures, and low moisture. Some cacti and succulents, such as Schlumbergera, enjoy semi-shade and wet circumstances because they are native to a rainforest environment.
It’s preferable to try to imitate a cactus or succulent’s natural habitat when caring for them. Here are the most important things to keep in mind when caring for cacti and succulents.
Light, temperature and ventilation
Cacti and succulents thrive in bright environments, and it is ideal to place them in a bright location. A south-facing location will provide ample sunlight; however, avoid placing them in full sunlight, as the bright light may cause the plants to become yellow. The right amount of light depends on the type of cactus or succulent you’re cultivating. Forest-growing epiphytes, like Rhipsalis, require semi-shade, whereas an Echeveria requires strong light.
Keeping the plants cool at night with temperatures of around 8°C to 10°C is optimal during the fall and winter months. In the spring and summer, the plants require sufficient ventilation but can endure high temperatures.
Compost
A free-draining compost, such as Westland cacti and succulent potting mix with additional girt and sand for excellent drainage, is a suitable choice. It also has the perfect amount of nutrients for your succulents and cacti.
Watering and feeding
Cacti and succulents are frequently misunderstood as simply requiring a modest amount of water. Even though their leaves and stems contain water-storing properties that help them to survive in dry environments, they will not thrive in a dry environment. Watering is crucial to the success of your cactus or succulent. Overwatering stunts growth, while underwatering results in shrivelling.
Instead of tap water, tepid rainwater should be utilized for irrigation. Because the minerals in tap water build up in the soil and produce deposits on the leaves, this is a good idea. Minerals also obstruct the plant’s ability to absorb critical nutrients.
Spring and summer
Water the plants at least once a week during the growing season. When watering, make sure the soil gets a good soak and that any surplus water drains away. Between waterings, allow the compost to dry out gradually.
Once a month, feed your plants with Westland Cactus and Succulent Feed, which is a wonderful mix to use. It aids in the production of healthy growth, increased disease resistance, and improved flowering. Simply take a 5ml quantity of the feed from the dosing chamber and mix it with 1 litre of water.
Autumn and winter
This is the moment when the plants go into dormancy. Reduce the amount of watering so that the potting mix dries out between waterings. The frequency with which they are watered is determined by the environment they are in as well as the succulent variety. Winter-flowering cacti require warmth and regular watering during this period, although desert-dwelling cactus can be left unwatered. Cacti and succulents do not require feeding during this time.
Re-potting
If your cactus or succulent is pot-bound, spring is the perfect time to re-pot it. To re-pot, follow these steps:
- To remove the plant from the container, first water it and allow it to drain before carefully taking it from the pot, using folded paper to protect your hands from the spikes.
- To avoid damaging the roots, remove the old soil from the roots with a thin stick, such as a chopstick.
- Place the plant in the new pot, which is slightly larger in diameter, and cover it with a coating of potting mix.
Maintaining these settings ensures that your cacti or succulents receive the greatest possible care. Most importantly, keep in mind that you are attempting to mimic your plant’s natural habitat when caring for it.
