- 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 types of holiday 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!
Do Christmas cactus need a lot of 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 per day to start the production 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.
Placing the Christmas cactus on the window sill in a cold room and not turning on the lights is all that’s needed. 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 can you tell if a Christmas cactus is overwatered?
Although sagging, limp leaves and stems that are mushy at the bottom are strong indicators of overwatering and root rot, the only way to know for sure is to examine the plant’s roots.
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 long can Christmas cactus go without water?
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.
Should I water my Christmas cactus while it’s blooming?
- 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.
How many times a year does a Christmas cactus bloom?
Is It Possible For A Christmas Cactus To Bloom More Than Once A Year? Yes. Christmas cactus, unlike many other succulents, can bloom again in the spring if given the right conditions.
What kills a Christmas cactus?
Although the Christmas cactus is easy to care for and requires little maintenance, it is prone to root rot. In most cases, this terrible fungal illness is caused by incorrect watering rather than inattention.
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!
Are coffee grounds good for Christmas cactus?
Your Christmas cactus will appreciate a cup of coffee just as much as you! Coffee grounds are high in potassium and nitrogen, which the cactus requires to stay healthy. You should not use the grounds right away since damp grounds can mold, so spread them out to dry first.
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.
