Drought stress or too much light, as it is a short-day plant, are the causes of Christmas cactus not blooming. The Christmas cactus has evolved to thrive in humid, rainy environments. If it’s too dry or there are too many hours of sunshine during bloom creation, it won’t flower.
There are a number of other reasons that can hinder the Christmas cactus (Schlumbergera) from blossoming, which I’ve included below:

How do you get a Christmas cactus to bloom?
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.
Why is my cactus not flowering?
Cacti are fascinating, exotic plants that add an abundance of unique grandeur to homes and gardens. If your indoor cacti aren’t flowering, it’s most likely because of a lighting, temperature, soil, or water issue. Also, some cacti species might take up to 50 years to reach flowering maturity! When purchasing a cactus from a garden shop or nursery, choose one that is in bloom to ensure that it is old enough to bloom.
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 is wrong with my Christmas cactus?
- Basal stem rot is easily identified by the appearance of a brown, water-soaked patch at the base of the stem, which occurs most commonly in cool, damp soil. The lesions ultimately make their way up the plant’s stem. Unfortunately, basal stem rot is usually fatal since the diseased portion is cut away from the plant’s base, removing the plant’s supporting structure. Starting a new plant with a healthy leaf is the greatest option.
- Plants with root rot, on the other hand, are difficult to rescue. A wilted appearance and wet, black or reddish brown roots are signs of the illness, which causes the plants to wilt and eventually die. If you catch the disease early enough, you might be able to rescue the plant. Take the cactus out of its pot. Remove the fungus by rinsing the roots and trimming any decaying portions. Repot the plant in a pot with a cactus and succulent-specific potting mix. Make certain that the pot has a drainage hole.
Because individual pathogens are difficult to diagnose and each pathogen requires a separate fungicide, fungicides are frequently useless. Water the plant thoroughly, but only until the potting soil feels slightly dry, to avoid rot. Allow the water to drain from the pot and do not allow the plant to sit in it. During the winter, water sparingly but never completely dry up the potting mix.
How often should 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!
What month does cactus bloom?
Cacti, in general, are flowering plants. As a result, practically every cactus species can flower if it is old and grown under the correct conditions. The age of your cactus plant and the care you provide it will determine whether or not it blooms. Some cacti plants bloom at a young age, while others do not bloom until they are at least 30 years old.
What is the average number of times a cactus flower blooms? Cacti flowers at least once a year on average, while wetter years may result in multiple flowering periods. The majority of cacti species flower in the spring when the weather is near ideal. In April, the greatest variety of spring-flowering cacti species can be seen. Certain bloom long into May, with some species, such as the prickly pears cactus, blooming as early as May. Saguaros bloom between mid-May and mid-June.
When should you put a Christmas cactus in the dark?
Place the mature plant in a dark room or keep it covered (under a box or bag works good) for at least 12 hours a day in late September or early October.
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.
How do I force my cactus to flower?
Succulents and cacti prefer a significant temperature change between night and day, as well as summer and winter months. Succulents prefer colder nighttime temperatures of 50-550F (10-130C) outside or at least 60-650F inside (15-180C). Succulents prefer a significant temperature differential between night and day temperatures, especially when kept in a controlled setting, to simulate their natural habitat, with the low night temperatures playing an important role in the plant’s growth cycle.
If you want to see your cacti and succulents bloom, you’ll need to overwinter them. Desert cactus, in particular, might benefit from keeping cold and dry during the winter months. During the winter, keep them cool by keeping the temperature between 35 and 440 degrees Fahrenheit (1.5-70C). If you must keep them indoors during the winter, keep them in a non-heated room or maintain the temperature low to provide them the chilly winter time they require. Holiday cacti like as Rhipsalis, Schlembergera, and Hatiora have different hydration and temperature requirements than desert cacti (see below for Holiday cactus blooming tips).
Ensure that the plants get enough sunlight all year and are kept in a bright position, even during the colder winter months. The majority of cacti and succulents require at least 4-6 hours of bright sunshine per day, if not more. Some plants cannot tolerate direct sunlight and require filtered but bright light to avoid sun damage. Plants that don’t get enough light eventually etiolate, become pale, and extend out in search of more light. Indoors, place plants in windows that face south or east to ensure ample lighting. Consider utilizing grow lights to offer enough light indoors if necessary. Succulent plants that don’t get enough sunshine don’t grow well and aren’t likely to flower as well.
While fertilization isn’t required, providing your plants with the nutrients they require will help them grow properly and bloom. Plants expend a lot of energy to develop flowers, thus supplementing their nutritional needs during flowering season will help. Fertilizing during the active growing season, or during the spring and summer months, is the most popular recommendation. Fertilizers should be administered every two weeks at a quarter or half strength. Fertilize less near the conclusion of the fall season and during the winter months. A balanced fertilizer blend diluted to half strength is appropriate and widely used. Fertilizer blends designed specifically for cactus and succulents can also be used.
Despite the fact that cacti and succulents can store water, they nevertheless need to be watered on a regular basis during the active growing season. Watering them on a regular basis ensures that they don’t run out of the water they need to grow. Watering them on a daily basis also enables them to better withstand the hotter summer months. Water plants thoroughly during the active growing season until water leaks out of the holes in the pot. Wait until the earth is completely dry before watering again. Before watering, feel the top inch of the soil for wetness. Watering frequency should be increased during the hot summer months and decreased during the cold winter months. Succulents and cactus suffer from overwatering, so make sure to let the soil dry out between waterings.
Succulents and cacti require a well-draining soil in addition to suitable watering practices. Succulents and cactus dislike being submerged in water. If their roots are left moist for too long, they will decay. The capacity to drain well is the most crucial feature of a succulent potting mix. You can use a commercial potting mix or make your own succulent potting mix. They have a better chance of surviving and blossoming if you give them the correct medium. Maintaining a nice environment for your plants will encourage them to flourish.
