- 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 sufficiently dry. To catch the water, place a tray underneath the pot. Remove any excess 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 to 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 blooming because it’s getting too much light 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 while 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 during the winter; it will bloom the following year!
How can you tell if a Christmas cactus is overwatered?
Although sagging, limp foliage and stems that are mushy toward the bottom are strong indicators of overwatering and root rot, the only way to know for sure is to examine the plant’s roots.
Does Christmas cactus like sun or shade?
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 live in 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 nothing 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 best 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 blooming, 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 much water do you give a cactus?
Take a look at the container you’re going to use before you repot the cactus. Yes, a pot with drainage holes is the best option because it eliminates the risk of stagnant water in the bottom. Cacti can also be grown in containers without drainage holes; it simply takes a little more attention. Always check to see if the soil is completely dry between waterings. Another approach is to measure the amount of water you use to ensure you don’t drown your cacti by accident. Depending on the season, a quarter to half cup per week or two is adequate to keep your cactus alive.
Do you water a Christmas cactus from the top or the bottom?
Remember that Christmas cactus plants prefer moist soil rather than the dry soil 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.)
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 dreaded fungal disease is caused by improper watering rather than inattention.
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 home, you’ll need to mimic some of the native habitat’s watering and humidity conditions.
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 increase humidity and reduce water loss through 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 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 partially shaded area 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 say 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.
Why are the leaves on my Christmas cactus limp?
A lack of water or too much direct sunlight can cause wilted or limp Christmas cactus. If you haven’t watered the wilting Christmas cactus, start by giving it a small drink. Continue to water sparingly every few days until the soil is moist but not saturated.
Christmas cactus problems are also caused by wet soil. Because the Christmas cactus is an epiphyte that takes water and nutrients from the air in its natural habitat on the tropical forest floor, it cannot tolerate damp roots. Christmas cactus can become very limp because to poor drainage and damp roots.
If the leaves on your wilted or limp Christmas cactus appear to be dried or burnt, move it to a more shady location, especially in the afternoon.
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.
How do you know when a cactus needs water?
A thirsty cactus (one that isn’t getting enough water) will exhibit the following symptoms:
- As the water reserves stored within the cactus are depleted, it will pucker or shrivel.
- The cactus will begin to fade. The Cactus frequently becomes brown or loses its natural shade or brightness as a result of this.
When their cactus houseplant exhibits these characteristics, many people become concerned. Fortunately, underwatering a cactus is safer than overwatering it.
If your cactus is displaying indications of dehydration, you can remedy the situation by watering it thoroughly as soon as possible. The plant should plump up fast, and the color should return to normal in a short period of time. Cacti that have been under watered bounce back faster and easier than those that have been overwatered.
I have a great article that explains how to tell when indoor plants need to be watered in more detail. I genuinely feel that learning to recognize the cues that your houseplants are giving you is the only way to improve your houseplant care, and getting it correctly is so satisfying.
