They favor direct, bright light. As the plants start to burn in full light, the leaf segments might turn a dark red color. The two factors of light and temperature are the “secret” to getting Christmas cacti to bloom the years after purchase. These two hold the secret to the realm of flowers.
How can a Christmas cactus be made to bloom again?
Yes. In contrast to many other succulents, If the Christmas cactus is given the right conditions, it can bloom again in the spring. Christmas cactus can be encouraged to bloom once more by placing it in the east-facing window, which gets plenty of light during the day and 12 hours of darkness at night.  
As soon as the buds start to appear, which should be at least six to eight weeks from now, make sure your succulent is kept dark and cool.
Your Christmas cactus may experience bud growth followed by bud drop if it is exposed to drafts, excessive heat, sunlight, or water.
It can take up to twelve weeks for flowers to fully develop after the bud stage. Make sure to move the plant to a bright, draft-free area once it blooms. Put it somewhere that doesn’t get direct sunlight, though. You will see more blooming when it receives indirect bright sunlight. As your Christmas Cactus blooms, you should give it more water; the amount will depend on the temperature, the lighting, and the humidity.
Why doesn’t my Christmas cactus bloom?
Due to its short day length, the Christmas cactus cannot blossom due to drought stress or excessive light exposure. Christmas cacti are adapted to wet, frequently rainy jungles. If the conditions are dry or there are too many hours of sunshine during bloom production, it does not flower.
I’ve listed here a few other reasons that can stop the Christmas cactus (Schlumbergera) from flowering:
Continue reading to learn why your Christmas cactus isn’t blossoming and the finest methods for putting remedies in place so that it can produce blossoms.
Will a Christmas cactus naturally bloom?
Give your loved ones a gift they will cherish for years to come, season after season. This lovely zygocactus, sometimes known as a Christmas cactus, is available in cheery hues and sizes. Watters Christmas Cactus is a lovely flowering plant for the holiday season with a swirl of hues in shades of golden, pink, red, and white. Just in time for the Christmas celebrations, our head grower has a keen sense of color. The vibrant colors that these blossoms offer will delight you.
You might believe that a cactus would make a unique Christmas plant. In the middle of winter, the Christmas cactus (Schlumbergera bridgessii) is a most welcome sight when it is covered in blossoms.
Your Christmas cactus will bloom on its own with very little maintenance. It might not, though, bloom in time for the holidays. You must force your plant into dormancy around 8 weeks before you want flowers if you want it to be fully displayed throughout the holiday season. Although it seems difficult, it really doesn’t take much work. Remembering to do it is the most difficult part.
GETTING YOUR CHRISTMAS CACTUS TO BLOOM
You’ll probably need to encourage your Christmas cactus out of dormancy and force it to bloom in order to have it blossom at Christmas.
Reduce watering by mid-October. Just water when the ground feels dry, which is usually about an inch below the surface. When forcing, avoid fertilizing.
Maximum Light
Reduce the quantity of light the plant receives gradually. The plant can continue to get indirect sunlight throughout the day, but at least 12 to 14 hours of complete darkness are required for the flower buds to open at night. (If the temperature in the room is higher than the recommended 50 to 55 F, add a few more hours of darkness each day.) Your Christmas cactus should be placed in a closet or room with a door that is kept closed at night. You will also need to take the extra precaution of covering the plant with a dark cloth or bag if light leaks in from under the door. Keep doing this treatment for six to eight weeks. You ought to then notice flower buds forming on the stems.
Once you spot blossom buds, take your Christmas cactus out of the shadows and place it close to a bright window. Make sure it is not near any drafts or it will lose its buds due to the cold.
Within a few weeks, the flowers ought to begin to open. The plant should continue to bloom for four to six weeks, and each blossom should remain open for at least six days, if not longer.
GROWING TIPS
The Christmas cactus is a native of tropical rainforests, in contrast to the desert-loving cacti that many of us are accustomed to, and it need frequent water to stay healthy.
Grow your Christmas cactus as a hanging plant or set it somewhere with space for it to dangle to stimulate new stems. Don’t be concerned about bumping into it. The plants of the Christmas cactus lack thorns.
- Although Christmas cacti have been known to bloom lavishly when placed in a bright, frosty window, they prefer diffused light. They can easily adjust to changing growing environments.
- Water the plant well, letting the extra liquid drain through the drainage hole. Between waterings, let the soil almost fully dry out. Never allow moist soil to stand. When the leaves begin to pucker and shrivel, the soil is too dry.
- The Christmas cactus also requires humidity, especially in the dry conditions of warm dwellings. Either spray the plant or set a tray of stones in water underneath it. The water should not come in contact with the pot’s bottom.
- Feed Watters Root & Grow at half the suggested strength once a month as fertilizer. When the buds form, withhold this cactus feeding; continue it after flowering.
- The Christmas cactus doesn’t care too much about the temperature. They prefer temperatures between 70 and 80 F. 55 to 65 F during the growing season and during setting buds.
OTHER TIPS
- Avoid opening doors frequently and drafty windows. They dislike rapid drafts and, if exposed to them, will shed their buds or flowers.
- After flowering, minor pruning gives the plant new life.
- If Christmas cacti are maintained slightly pot confined, they tend to bloom better.
- If your Christmas cactus blooms occasionally throughout the year, don’t be shocked. That’s what a joyful Christmas cactus does.
- This plant has an incredibly long lifespan and is simple to grow from cuttings.
- Older plants bloom even more frequently than young Christmas Cacti do.
- Neglect seems to be beneficial for Christmas cacti. Avoid the urge to fuss over them.
How often do Christmas cacti bloom each year?
Whichever one you have, it’s possible for them to bloom more than once a year. For Your Reference, Here Are A Few Of Our General Houseplant Guides: Watering Indoor Plants: A Guide. Beginner’s Guide To Plant Repotting.
How do I get my cactus to bloom?
Cacti and succulents prefer summer and winter seasons, as well as a clear variation between night and day temperatures. Succulents prefer colder outdoor nighttime temperatures of 50-550F (10-130C) or at least 60-650F indoor nighttime temperatures (15-180C). Succulents prefer a noticeable contrast between their night and day temperatures to imitate their natural habitat, with the low night temperatures playing a crucial role in the plant’s growth cycle, especially when kept in a controlled setting.
If you want to see your succulents and cacti bloom, overwintering is also crucial. For desert cacti in particular, this can be accomplished by keeping plants cool and largely dry over the winter. During the winter, keep them at a comfortable temperature of between 35 and 440 °F (1.5-70C). If maintained indoors during the winter, try to keep them in an unheated room or keep the temperature low to provide them the necessary cold winter season. This does not apply to holiday cacti, such as Rhipsalis, Schlembergera, and Hatiora, which have different moisture and temperature needs than desert cacti (see below for Holiday cactus blooming tips).
Make sure the plants are kept in a bright area and receive enough sunshine throughout the year, including during the darker winter months. Most succulents and cacti require at least 4-6 hours of bright sunshine every day, if not more. Some plants require filtered but bright light to avoid solar damage since they cannot withstand harsh, full sun. Lack of light causes plants to gradually etiolate, become paler, and spread out in search of more light. To provide adequate lighting, place indoor plants in windows with a south or east orientation. If more light is required indoors, think about using grow lights. Lack of sunshine stunts the growth of succulent plants, and they are unlikely to blossom as effectively.
Giving your plants the nutrition they require instead of fertilizing them will assist maintain healthy growth and promote blooms. Flowers require a lot of energy to grow, therefore giving plants more nutrients during flowering season will assist meet their nutritional requirements. The best time to fertilize is during the active growing season, which is in the spring and summer. Fertilizers work best when applied every two weeks at a quarter- or half-strength. Avoid fertilizing during the winter and towards the conclusion of the fall growing season. It is acceptable and typical to use a balanced fertilizer blend that has been diluted to half strength. Cacti and succulent-specific fertilizer mixtures are also appropriate.
Although cacti and succulents can store water, they still require frequent watering during the active growing season. Regular watering helps to guarantee that they don’t lose all the water they need to store for growth. Regular watering also improves their ability to resist the hotter summer sun. Water plants thoroughly during the active growing season until water begins to leak out of the pot’s openings. Don’t water again until the soil has dried out. Before watering, check the top inch of the soil for moisture. During the hot summer months, watering should be done more frequently; during the chilly winter months, less frequently. Succulents and cacti suffer from overwatering, so make sure to let the soil dry out in between waterings.
Succulents and cacti require a well-draining soil in addition to suitable watering methods. Cacti and succulents don’t like to sit in water. If left moist for too long, their roots are prone to rot. The capacity of a succulent potting mix to drain efficiently is its most crucial requirement. You have the option of using store-bought potting soil or making your own for succulents. Giving them the proper medium increases their chances of flourishing and blossoming. Keeping your plants content will boost blooming.
Does Christmas cactus benefit from Epsom salt?
The winter solstice, which occurs on December 21 in the Northern Hemisphere, is the day and night with the shortest lengths of the year.
Christmas cacti, poinsettias, kalanchoes, and chrysanthemums are a few common plants that people give as gifts during the holidays. Their flowering is perfectly timed for the shorter days that we enjoy during this season.
The development of flower buds in many plants is influenced by how much light the plants receive. “Photoperiodism” refers to a plant’s response to the length of the day. While some plants flower as the days get shorter, others do so as the days become longer. Some plants are neutral, meaning that day length has no direct impact on flowering.
Brazilian Christmas cacti are common indoor plants that come in a wide range of hues, including red, rose, purple, lavender, peach, orange, cream, and white. In shaded rain forests, these plants thrive as epiphytes among tree branches, and their cascading stems make them an excellent choice for hanging baskets. If the plants are managed at a temperature of 68 degrees Fahrenheit, flowering can last seven to eight weeks.
During this time of year, customers frequently phone the University of Georgia Cooperative Extension office upset because their Christmas cacti or other short-day indoor plants did not bloom. They are frequently shocked to discover that if these plants are kept indoors year-round, the artificial light in the home can interfere with their natural cycle of exposure to sunshine. In order to simulate natural daylight exposure with shorter days, it becomes a difficulty.
One option is to put these plants near a window in a room that receives only natural light, turning off the artificial lighting at night. A different choice is to keep these plants outside as long as you can in the fall and then bring them inside just before the risk of freezing weather. In the Atlanta region, this typically means keeping the majority of tropical indoor plants outside until close to the end of October. Short-day plants are already set to begin flowering during the approaching holidays at this point.
On his porch, my grandfather used to keep a Christmas cactus all summer long in a hanging basket before taking it inside just before the first freeze each year. It was a large plant that would blossom in large numbers between Thanksgiving and Christmas. He maintained this plant for almost ten years, and it gave him a lot of Christmas delight.
A Christmas cactus has the advantage of not losing leaves like poinsettias or other houseplants, which is one of its many advantages. Because Christmas cactus lack genuine leaves, photosynthesis takes place inside the green stem segments known as phylloclades. To encourage branching terminals for more flowers, pinch back the stems in the first few weeks of June. You can also utilize stem portions with three to five segments to root new plants.
Temperature control and photoperiod (control of day and night length) control are key factors in the fall flower bud formation of Christmas cacti. Before flower buds will set, each night must have at least 14 hours of nonstop darkness.
For a full bud set, long nights must begin around the middle of September and last for at least six weeks. Be aware that even two hours of intermittent lighting can prevent flower buds from setting. Typically, buds will appear in approximately four weeks. Once the buds are set, the photoperiod has little impact on flowering.
Christmas cacti may live in dry, marginally submerged environments in the spring and summer. Avoid letting the soil become soggy, especially during the lengthy winter evenings. To stop flower buds from dropping off after bud set in the fall, the soil must be kept consistently moist. In the saucer underneath the pot, never let water stand.
From the time new growth begins in late winter or early spring through the summer, fertilize plants every month using a liquid fertilizer of half strength, such as 20-20-20 with trace elements. Compared to many plants, Christmas cacti have a greater magnesium need. Epsom salts (magnesium sulfate) should be used as a fertilizer every month during the growing season; however, it should not be used the same week as conventional fertilizer. Stop fertilizing in the late summer to increase the formation of bloom buds in the fall.
