After it has finished blooming, you can prune your Christmas cactus to make it larger and bushier, but never after late spring. Simply pinch off one or more of the parts to trim the plant. If you want to grow more plants from them, replant them in different pots.
How can a Christmas cactus be made to bloom?
Understanding the Christmas cactus bloom cycle—little water, dormancy, light, and temperature—will help you force a Christmas cactus to bloom.
Start by minimising how much water the plant gets. This often occurs sometime in the fall, usually in or around October or the beginning of November (in most places).
Just enough irrigation should be reduced to keep the soil moist. Only water until the top 1 inch (2.5 cm) or so of soil feels dry to the touch. The plant will be able to go into dormancy as a result. A Christmas cactus needs to be dormant in order to blossom.
You must relocate a Christmas cactus such that it will experience 12 to 14 hours of darkness in order to further force the plant to bloom. While Christmas cactus can tolerate bright, indirect light during the day, it needs at least 12 hours of complete darkness at night to promote bud formation.
In addition to dark surroundings, your Christmas cactus needs cool temps. It should be between 50 and 55 degrees F on average (10-13 C.). As a result, confirm that the location can satisfy the needs for both light and temperature.
How can I increase the bushiness of my Christmas cactus?
Pruning a Christmas cactus is arguably one of the simplest pruning tasks because of the unusual stems. Giving the stems of a Christmas cactus a brief twist in the space between two of the segments is all that is required to prune it. You can also cut the segments off your plant with a good knife or pair of scissors if this seems a little harsh.
You can cut down a Christmas cactus by up to one-third of the plant each year if you want to make it smaller. You simply need to remove the last one to two segments of the stems from Christmas cactus plants in order to encourage them to fill out more completely.
The really enjoyable aspect about clipping a Christmas cactus is that you can quickly root the cuttings and offer your friends and family fresh plants.
Reason 1: Not Enough Watering
The first and most obvious possibility is that you either failed to water your cactus or that you do it too infrequently or insufficiently.
Christmas cactus and its relatives are tropical epiphytic succulents, not real cacti, as I’ve previously stated. As such, they require more water than typical cacti, though not an excessive amount.
Reason 2: Too Much Watering
The second cause of your limp is Unfortunately, the Christmas cactus is both more prevalent and dangerous.
A Christmas cactus is an epiphyte, meaning its roots are shallow and somewhat weak, and they haven’t evolved to withstand a damp environment. Additionally, the stems of succulents are vulnerable to overwatering.
All of this means that persistent overwatering has the potential to quickly result in root and stem rot. There is still hope even though it is difficult to stop and reverse the decaying once it has begun.
Due to decay, the plant’s roots and/or stem are physically unable to absorb water, which causes it to wither and become limp.
How can a leggy Christmas cactus be fixed?
The two plants I used for this article’s photographs are between two and 10 years old. Neither is especially large. I’ll use them to illustrate why you should annually prune your Christmas cactus.
Prune a Scraggly Plant to Fill it In
If your Christmas cactus has only legs, you might want to clip it to make it grow more fully rather than longer. In order to achieve this, you will need to pinch back leggy growth in order to urge the plant to grow outward rather than longer.
When the plant is young, it is considerably simpler to accomplish this. When the plant has reached the desired degree of bushiness, you can focus your pruning efforts on general maintenance. While the plant is still young, you can guide it to grow in the direction and area of your choosing.
Prune Your Christmas Cactus to Maintain Its Shape
Your Christmas cactus may be ideal just the way it is. Great, you should cut back on excess growth each year to keep that shape. If you have a problem with space, this is extremely critical. Cut off any lengthier segments that are beginning to feel a little uncomfortable.
Similar to getting a haircut, frequent pruning will result in a strong and healthy plant. Additionally, because the plant can focus its energy on producing buds rather than more energy-intensive new stems, you’ll get more blooms.
When it blooms, should I fertilise my Christmas cactus?
Make sure you have a decent location for the plant to grow because, to begin with, the plants do best in indirect sunshine and well-drained soil. The Christmas cactus has a feeding and growing season that coincide. This indicates that it will require feeding just before it blooms, which should occur between April and October of the current year. Just in time for Christmas, with the right fertiliser and a regular feeding schedule, you ought to have vibrant blossoms.
These plants will bloom during the shorter, cooler days of the fall since they require 12 hours of light and 12 hours of darkness to develop. For the greatest results when fertilising this plant, choose a bloom formula or a water-soluble formula. To assist the flowers blossom more beautifully in the middle to late summer, fertilise once a month with a high-phosphorus fertiliser.
It’s crucial to make sure you cease feeding the plant after it stops growing, which will happen late in the summer. The salt can accumulate in the bud and prevent it from flowering if you keep feeding the plant even when it is not actively growing. Never fertilise a Christmas cactus when it starts to bloom since this could make the buds fall off.
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 utilise 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, fertilise plants every month using a liquid fertiliser 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 sulphate) should be used as a fertiliser every month during the growing season; however, it should not be used the same week as conventional fertiliser. Stop fertilising in the late summer to increase the formation of bloom buds in the fall.
Do Christmas cacti benefit from coffee grounds?
During the growing season, give your cactus fertiliser with potassium, nitrogen, and phosphorus once or twice a month. It is simpler to feed a plant when the fertiliser dissolves in water. Epsom salts can also be administered to it (more about this in a moment).
Do Christmas Cactus Like Coffee Grounds?
As much as you do, your Christmas cactus will appreciate a cup of joe. Potassium and nitrogen, two nutrients the cactus needs to be healthy, are abundant in coffee grounds.
Spread the grounds out to dry first before using them because wet grounds might get mouldy if used immediately. Give your plant its daily dose of coffee by either dispersing the dried grinds on the soil or blending them with water. Use this method to fertilise your cactus no more than once every two weeks.
Is Epsom Salt Good For Christmas Cactus?
Your Christmas cactus will, in fact, enjoy some Epsom salt. It’s an excellent approach to guarantee that the plant receives all the magnesium it requires to flourish and expand. One teaspoon of salt should be added to one gallon of water when mixing the salt and water. As it only requires fertiliser and food during the spring and summer growing seasons, stop feeding it in the fall.
Which fertiliser is ideal for Christmas cacti?
A half strength water soluble fertiliser, such as 20-20-20 or 20-10-20, or a bloom formula houseplant fertiliser work well as fertilisers for Christmas cacti. From late winter through late summer, feed once a month during routine watering. To promote flowering, you can also choose a time-release balanced plant food or one that is marginally richer in phosphorus once a month in mid to late summer.
Use one teaspoon of Epsom salts per gallon (5 cc for roughly 4 L) of water each month to fertilise on alternate weeks. This procedure will meet every fertiliser requirement for Christmas cacti, including the significant magnesium requirements of this epiphyte. Late summer is the time to stop fertilising or flower yield may decrease. Since the plant is not actively growing in the winter, fertilising is not necessary.
To lessen the likelihood of salt buildup in soil, closely adhere to the application rates on any formula. Set the plant in the shower and soak the soil to release any salt that has been stored if you are concerned about heavy salts. Before watering again, let the pot drain completely and the planting media dry out.
Should Christmas cactus be pruned?
Pruning. After it has finished blooming, you can prune your Christmas cactus to make it larger and bushier, but never after late spring. Simply pinch off one or more of the parts to trim the plant. If you want to grow more plants from them, replant them in different pots.
When should my Christmas cactus be repotted?
The best time to repot most plants is in the spring when they start to show new growth, but Christmas cacti should be potted after blooming is finished and the blooms have faded, which is in late winter or early spring. It is never a good idea to try to repot the plant when it is in full bloom.
Repotting Christmas cactus should be delayed because this tough succulent thrives when its roots are little congested. Frequently repotting a plant might harm it.
Repotting Christmas cactus is typically sufficient every three to four years, but you might wish to hold off until the plant starts to appear worn out or you see some roots poking through the drainage hole. A plant can frequently flourish happily in the same pot for years.
Do Christmas cacti enjoy having their roots bound?
Do Christmas cacti enjoy being rootbound? I was told not to repot it because it is currently healthy. D. Forrest
SUMMARY: Christmas cactus tolerates dense root systems well, so your friend isn’t entirely mistaken. Although Christmas cacti can still thrive after becoming rootbound, you should still repot your holiday plants every four years, expanding the container size by two inches each time.
Repotting a Christmas cactus can be difficult since, if the plant becomes rootbound, doing so might easily cause damage to the plant. Breaking the pot is the quickest way to remove it without harming the plant. It’s not a major loss because clay pots are inexpensive, and it’s much simpler to rehome your cactus without harming it.
If you notice your planter’s soil getting harder over time, observe roots poking out of the drainage hole or holes, or notice that the stems of your Christmas cactus are beginning to turn yellow or brown, your cactus may be root-bound (the latter symptom is also sometimes a sign of overwatering, not overcrowding). If you see these symptoms, you can leave your plant in its overcrowded container for a few more weeks or even months because it actually prefers the crowding. But ultimately, you’ll want to repot your cactus to give it more space and, in the process, provide it with newer, healthy soil.
To speed up water drainage, use potting soil designed specifically for cactuses and succulents. Fill the new, larger replacement planter with enough fresh soil so that the top of the root ball will rest about an inch below the rim. Remove a significant amount of the old soil from the roots and root ball by gently brushing off the root ball. To remove the majority of the oil soil from the roots and root ball, you can choose to wet or rinse them with water.
Then, carefully fill the space surrounding the root ball with the new, fresh potting soil that was designed for desert plants after placing your cactus in its new pot. While repotting, take out any stems that have yellowed or dried out. When the new dirt is securely planted, water your Christmas cactus thoroughly and choose a shaded location to put it for a few days so that it can get used to its new surroundings, the new soil, and the extra room.
During the spring and summer, keep your cactus in a shaded area of the porch or patio where they can receive plenty of fresh air and indirect sunshine. If you prefer, you can take a few cuttings each fall and give them out as gifts once they have grown. Bring them indoors in the fall and store them away from direct sunlight in a dry, dark area. Your Christmas cacti will thrive exceptionally well if you can create a slightly humid indoor environment.
Start drying the soil in October to promote blooming during the holiday season. Reduce the frequency of watering to only once every three weeks instead of once a week. For holiday blooms to flourish, darkness and dryness are both necessary conditions. To enhance the flowering of their Christmas cacti, some gardeners go so far as to cover their plants and keep them in the dark for a few weeks.
