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 I get my Christmas cactus to bloom?
We’ve all had those moments when we want our garden to look its best, with all of the feature plants blooming and everything looking lovely and healthy.
Fortunately, there are a few simple things you can do to ensure that your Christmas Cactus blooms when you want it to. To get those blossoms out in the open, you only need to provide the correct habitat for the Christmas Cactus.
Step 1 Reduce/Limit Watering
The first step is to cut back on the amount of water you give your Christmas Cactus.
Before watering the succulent, wait until the top inch of soil around it is dry, and then only give it enough water to get the soil slightly damp.
Step 2 Reduce Light Received
We all know that plants enjoy light, right? Well, not in this case. To encourage the Christmas Cactus to bloom, keep it in the dark for 12-14 hours a day (overnight), and when I say dark, I mean dark as little indirect light as possible is ideal.
This is the most critical step in the process since it promotes bud development.
Step 3 Reduce Environment Temperature
The next step is to keep the Christmas Cactus cool; the temperature should be about 50-55 degrees Fahrenheit throughout the day.
As a result, ensure sure the area where your plant is kept is within this temperature range.
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 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!
Should Christmas cactus be watered when blooming?
Flower buds can drop more quickly if there is a lack of water or if the temperature changes dramatically. 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.
Why is my Christmas cactus blooming in May?
Christmas cactus, unlike many other succulents, can bloom again in the spring if given the right conditions. Christmas cactus can be encouraged to flower again by placing it in an east-facing window that receives plenty of sunlight during the day and 12 hours of darkness at night.
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.
How do I make my cactus flower?
Cacti require dormancy in order to blossom. When the temperature is below 15 degrees Celsius, the rest period normally lasts two to four months. Withhold water or fertilizer at this time and move the container to a cool, sunny location. Place the cactus in a bright area where it will receive lots of sunlight.
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.
Why are the leaves on my Christmas cactus limp?
A lack of water or too much direct sunlight can create wilted or limp Christmas cactus. If you haven’t watered the wilting Christmas cactus, start by giving it a small sip. Continue to water gently every several days until the soil is wet but not saturated.
Christmas cactus troubles are sometimes caused by damp 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.
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.
