Did you know that Christmas Cactus make hardy houseplants? Christmas Cactus are frequently sold throughout the holiday season. Both indoors and outdoors, I find them to be incredibly simple to grow, and mine always bloom once a year, typically twice.
They are absolutely fantastic, but like any plants, they can have faults and problems. I decided to write this piece because the leaves on my client’s Christmas cactus had turned orange. It seemed like too fantastic of a chance to miss.
Let’s get a little more technical for those of you who are plant nerds like me. Thanksgiving (or crab) cactus is what you are seeing here and in the video instead of Christmas cactus. It was marked as a CC when I purchased it, and that is how it is frequently offered for sale in the trade.
These days, they might be identified as Holiday Cactus. Any of them could experience this, no matter which one you have.
This plant is turning a deep bronze from its too orange state. The leaves are scraggly and sagging.
When under stress from the environment or culture, plants change hue. This one changed to a deep orange/brown/bronze color—the exact shade is up for debate! mostly as a result of water shortage. It has occasionally gotten a little too much sun. Dehydration is evident in the leaves’ thinness and wrinkles, which can be seen if you look closely at them.
At least six years ago, I purchased this Holiday Cactus at the Santa Barbara Farmer’s Market. It was a piece of the Christmas dish garden I created for my client’s front porch table. She resides on the coast approximately a quarter mile from the Pacific, one and a half hours south of San Francisco. This plant has managed to live despite the other plants having long since moved to the compost pail. Oh, and did I mention how tough Christmas cacti are? This is evidence!
Unlike the desert cactus that Tucson is covered in, these succulents are epiphytic cacti. Christmas Cacti grow on other plants and rocks, not in the soil, in their native rainforest habitats. They are shielded from full, direct sunlight by the canopies of trees and plants, and they flourish in this environment.
Changing Color
Christmas Cactus can become orange, brown, or golden when exposed to much sunlight because they prefer shade from it. Yellow leaves may also be an indication of excessive sunlight or moisture. In Santa Barbara, my Thanksgiving Cactus was an outside plant that turned burgundy or purple in the winter as a response to the chilly weather.
Early in December, the Thanksgiving Cactus was lying on its side on the opposite end of the front porch when I first went to my client’s house. She is close to the Pacific, so at least some moisture is provided by the fog where she resides. That, in my opinion, is what has kept it going.
Why is the pinking of my white Christmas cactus?
By restricting the amount of oxygen that roots can absorb and by weakening their tissue, overwatering harms them. Overwatering frequently results in root rot. Mushy tissue, wilting, and pink or reddish discolorations on the leaves are characteristics of Christmas cactus. An unpleasant odor in the soil is another indicator of root rot. A damaged plant needs to be replanted in new, unused medium and let to dry out for two to three weeks. Trim away the severely harmed leaves and gradually bring the plant back to its regular watering schedule by allowing the top inch of soil to become dry in between waterings. Pruning blades should be cleaned with rubbing alcohol before and after use to disinfect them.
What generates the red color on a Christmas cactus?
In USDA hardiness zones 10 to 12, Schlumbergera bridgesii, widely known as the Christmas Cactus, performs best indoors but also flourishes in sheltered outdoor situations. A mature Christmas cactus normally experiences few issues, while some could experience reddened leaves as a result of poor growing circumstances, diseases, or poor maintenance.
Cultural Stress
Christmas cactus frequently produces red foliage due to cultural stress, especially if it is exposed to direct sunlight in the summer or does not get enough water. This cactus thrives in light shade throughout the hotter months because it is a plant native to tropical forests. It does, however, like full sunlight in the winter and needs a little bit more water than most other cacti do. So once the soil feels dry 1 inch (2.5 cm) below the surface, it needs to be watered. Examine the light exposure of an established Christmas Cactus if its foliage turns reddish but otherwise seems healthy. If required, relocate it. Similarly, alter the soil’s moisture content and avoid letting it go too long without watering.
Root Infections
By restricting the amount of oxygen that roots can absorb and by weakening their tissue, overwatering harms them. Overwatering frequently results in root rot. Mushy tissue, wilting, and pink or reddish discolorations on the leaves are the hallmarks of Christmas Cactus. An unpleasant odor in the soil is another indicator of root rot. An injured plant needs to be replanted in new, unused potting soil and allowed to dry out for two to three weeks. Trim away the severely harmed leaves and gradually bring the plant back to a regular watering schedule by allowing the top inch (2.5 cm) of soil to become dry in between waterings. Pruning blades should be cleaned with rubbing alcohol before and after use to disinfect them.
Pathogen Infestations
If Christmas Cacti are propagated from sick plants or are potted in polluted soil, they may become infested with Cactus Cyst (Cactodera cacti). Cactus Cyst is a nematode that predominantly affects the roots but can also manifest as a wide range of symptoms in the foliage. Common signs include stunted growth, wilting, and reddish discolorations; however, the most telltale symptom is observed on the roots as tiny, pearl-like lumps. Cactus Cyst treatment is challenging and rarely effective, thus prevention is essential. To prevent contact with contaminated soil, first put the plant in fresh, sterilized soil in an unused pot and raise it off the ground. If a plant becomes infested, get rid of it to prevent the infection from spreading.
Nutrient Deficiency
Weeding and reddened or purple-tinged leaves are two typical signs of magnesium insufficiency, a common disease in Christmas Cacti. It mainly happens in the wintertime when feeding and watering are restricted and nutrient uptake by the plant is slowed down by the chilly weather. The cactus thrives in winter at temperatures between 55 and 65 F. (13 to 18 C). With Epsom salts, a magnesium deficit can be treated. A supplement feeding of 1 teaspoon of Epsom salts dissolved in 1 gallon (3.8 l) of water is typically helpful. Spray the tops and undersides of the foliage with the mixture after pouring it into a spray bottle. Every two weeks, reapply the mixture to the foliage until it takes on its natural hue.
What causes the purple-tinged Christmas cactus?
Your Christmas cactus leaves frequently have a purplish hue, which is typical. However, if it is conspicuously present throughout the leaves, it can indicate a problem with your plant. The following are the most typical causes of Christmas cacti’s leaves turning red or purple:
issues with nutrition
Your Christmas cactus may be deficient in essential nutrients if you don’t fertilize it frequently. From spring to mid-autumn, treat the plant every month with an all-purpose indoor plant fertilizer.
Additionally, since Christmas cacti require more magnesium than most plants, adding 1 teaspoon (5 mL) of Epsom salts to 1 gallon of water as a supplement to the plant’s diet usually works well. Throughout the spring and summer, apply the mixture once a month, but avoid using it the same week you apply conventional plant fertilizer.
dense roots
Your Christmas cactus could not be properly receiving nutrients if its roots are bound. This is one potential explanation for the Christmas cactus’ reddish-purple leaves. Don’t repot your plant until it has been in the same container for at least two or three years, but keep in mind that Christmas cactus flourishes with dense roots.
Repotting Christmas cactus is best done in the spring if you find that it is rootbound. Transfer the plant to a container that is filled with a potting mix that drains well, such as ordinary potting soil blended with perlite or sand. The pot has to be one size bigger.
Location
Christmas cactus needs bright light in the fall and winter, but excessive direct light in the summer may cause the leaves to become purple on the margins. It could be possible to avoid sunburn and fix the issue by moving the plant to a better place. Ensure that it is not near any open doors or drafty windows. In the same way, stay away from hot, dry locations like those near a fireplace or heating vent.
What is causing the mild greening of my Christmas cactus?
What is associated with watering? adequate drainage. The pot’s roots may get soggy and unable to absorb nutrients if moisture collects at the bottom of the container.
As a result, the roots may rot and produce more withering and discoloration from fungal infection. This can cause stem segments to wilt and turn pale green to yellow.
Make sure your container has at least one drainage hole on the bottom to prevent drainage problems.
Fine gravel, pumice, or sand should be included in the potting media to encourage root aeration and drainage.
You may go one step further and place a layer of stones at the bottom of the container to help prevent water from gathering, which can cause rotting.
When watering, avoid placing the pot in a dish of water that prevents airflow from the drainage hole.
Make sure the water level in the pan is no higher than the gravel if you need to place your tropical plants on a pan of wet gravel to maintain ambient moisture in a dry house. This will allow air to reach the drainage holes of the containers.
When should you put a Christmas cactus in the dark?
Put your Christmas cactus in complete darkness for at least 12 hours every day, beginning in October, to start blooming. In time for the holidays, the plant will have around eight weeks to develop buds and blossom as a result. To encourage your Christmas cactus to bloom again in February after the holiday flowering time, keep up this same pattern.
How long can a Christmas cactus live?
Christmas cacti can survive up to 100 years or longer if given the right care. Even news stories of families passing on their Christmas cacti to future generations as living heirlooms have been documented, such as this one about a particularly resilient plant that dates back to the 1860s. Wow!
The majority of Christmas cacti, however, only live for 20 to 30 years with proper care, despite the fact that they can last for decades and brighten your home every holiday season. By that time, the plants typically perish from widespread problems including overwatering, underwatering, freezing weather (if they spend part of the year outside), pests, illnesses, loss of interest, or simple neglect.
Help, my Christmas cactus is yellowing!
Yikes! Your watering routine is typically to blame if your Christmas cactus doesn’t seem to be growing well. These creatures require more water than desert cacti, but they also don’t want their soil to be wet.
You’re probably not watering your Christmas cactus enough if the leaves are becoming wrinkled and appear withered. You possibly overdid it if they’re more mushy and yellow-black in color. To get rid of any rotten roots and repot your plant in dry soil, you might need to uproot it.
Why are the leaves on my Christmas cactus limp?
Wilted leaves are frequently caused by improper watering because it is simple to provide too much water (rather than not enough). A Christmas cactus’ weak or drooping leaves are typically the result of either damp soil or root rot. If you have one issue, it will almost certainly lead to another.
Make sure that any extra water you give your Christmas cactus drains slowly but steadily through the drainage holes. If not, your potting soil may be too dense and may not be working. To promote aeration, you can repot the plant in bromeliad soil or fluff it up with perlite.
During the spring through winter growing season, keep the soil lightly moist; only water when the top inch of soil feels dry to the touch. After the flowering season is over, it’s good to allow the soil get a little bit dry in the middle of winter between waterings, but don’t let it get completely parched.
Is a Christmas cactus toxic to cats and dogs?
I’ll keep this short: no. The ASPCA states that Christmas cacti are not dangerous, despite the fact that ingesting any plant may cause some mild vomiting or diarrhea.
Is there a Christmas cactus that is yellow?
The yellow Christmas cactus is a succulent plant that was grown in a soil mixture made especially for succulent plant species that drains effectively.
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.
