Christmas cacti frequently suffer from a magnesium deficit, which manifests as drooping and foliage that is stained red or purple. 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. Wintertime temperatures between 55 and 65 degrees Fahrenheit are ideal for the cactus. With Epsom salts, a magnesium deficit can be treated. 8 heaping tablespoons of Epsom salts should be dissolved in 2 1/2 liters of water together with 1–2 drops of dishwashing liquid. 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.
A Christmas cactus with a woody stem may not experience any problems at all; as these plants become older, the stems become more resembling wood.
How are red leaves on a Christmas cactus fixed?
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 foliage are two typical signs of magnesium deficiency, a common disease in Christmas Cacti. It mostly 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 pinking of my Christmas cactus?
Here are a few additional Christmas cactus issues that are not diseases. Usually, these issues can be resolved quickly by making a few environmental changes or taking better care of your Christmas cacti.
LIMP OR WILTING CHRISTMAS CACTUS
One of three problems could be the cause of your Christmas cactus’ withering or seeming limpness. If you leave the issue unattended, it can develop into root or stem rot, so you’ll want to recognize it and fix it right once.
The soil can be too dry, too moist, or too root-bound. Use the process of elimination to identify the issue after probing the soil with your finger to a depth of about one inch.
Solution: Let the soil dry if it is only slightly damp before watering it once again. In order to avoid root or stem rot, it is best to promptly remove the plant from wet soil and repot it in dry soil.
If after watering there is no change, the cactus may be highly root-bound. Holiday cacti do enjoy having their roots bound, but eventually this becomes too restrictive for them to remain healthy. Try repotting your plant into a new pot with a drainage hole that is one size larger and filled with cactus soil if it begins to grow but then wilts back within a few days or if it doesn’t grow after watering.
CHRISTMAS CACTUS LEAVES TURNING RED OR PINK
Your Christmas cactus may be receiving too much sun or not enough water if its leaves are turning red or pink.
Solution: If your Christmas cactus is right next to a window that gets direct sun during the day, move it back. Although they can tolerate some sun, they prefer indirect light. Additionally, check the soil; if it is dry to one inch below the surface, water it more frequently. Water the Christmas cactus when the soil feels dry to the touch.
CHRISTMAS CACTUS WON’T BLOOM
There could be a number of reasons why your Christmas cactus doesn’t bloom. The Christmas cactus like to be somewhat rootbound, prefers stable temperatures, wants to be left alone, and requires extended periods of darkness in the fall to begin its flowering cycle. If you’ve just brought a little plant home, be patient. The older a Christmas cactus gets, the more probable and lavishly it will bloom.
The following actions can help your Christmas cactus blossom in time for the holiday.
Midway through October, reduce watering and only water when the soil is dry to about an inch deep.
For 6-8 weeks, give it 12-14 hours of darkness at night and indirect light during the day.
Close the blinds at night if the room has windows. You can gently cover the plant with a dark cloth or bag if there is still a lot of ambient light present even with the blinds and curtains drawn. If you’re going to cover the plant with a blanket or sheet, make a frame around it or even set it between two kitchen chairs to prevent breaking.
Return to watering after the buds begin to open and the soil seems dry.
CHRISTMAS CACTUS DROPPING FLOWER BUDS
If the flower buds on your Christmas cactus develop but all fall off before the plant blooms, what will happen? In that circumstances, it might be brought on by abrupt changes in temperature, humidity, light, or overwatering or by being moved.
You’ll just need to be patient if you recently moved your Christmas cactus to a new location, home, or room. Because they dislike abrupt environmental changes and prefer solitude, it will ultimately produce fresh buds and blossoms once more.
Your cactus may lose its buds if it has received too much water. Before watering, let the soil dry if it’s wet. Repot it into barely moist cactus soil right away if the soil is waterlogged to prevent root rot. It might still lose its buds, but ultimately it should grow new ones.
Your Christmas cactus may have lost its buds if the humidity in your home changed unexpectedly (for example, if you just turned on the heating). This is because it needs higher humidity. You can either set your Christmas cactus on a pebble tray or run a humidifier in the space.
CHRISTMAS CACTUS PESTS
The same common houseplant pests that affect other houseplants can infest Christmas cacti. Isolate your plant and treat the infestation with your selected solution if you notice any signs of an infestation.
Why is the color of my Christmas cactus changing?
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.
What is causing my Christmas cactus’ tips to turn purple?
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.
A Christmas cactus may receive too much sunlight.
According to information on how to care for Christmas cacti, they thrive in typical home settings with minimal attention. The Christmas cactus can tolerate low light levels, but if exposed to greater light, the plant will blossom more quickly. However, the Christmas cactus’s leaves can be damaged by excessive direct sunlight, so keep it in a suitable location to prevent this.
Additionally, moisture is crucial for Christmas cactus. During the plant’s active growth in the spring and summer, frequent and thorough watering is required to maintain a moist soil environment. Never let the Christmas cactus sit in water as this will cause root and stem rot. Instead, let the plant’s moisture levels fall and dry out a little between waterings. Every other week, a light fertilizer solution can also be applied to indoor plants.
The pinking of a succulent: what does it mean?
You might get really concerned if the succulent in your home turns pink because you think it might be dying.
In reaction to environmental conditions, succulents turn pink. It typically takes quite a bit of stress for some of the hardiest and most durable houseplants to change the color of their foliage.
You must keep in mind that succulents adapt to their settings, and when these environments or their care undergo unexpected changes, they will react since they do not handle sudden change well.
The most frequent stressors that lead to the pinking of succulents include excessive or insufficient sunlight, incorrect watering, root rot, temperature shifts, and nutrient deficiencies.
Too much sunlight
One of the most frequent causes of your succulent turning pink is because it is suddenly exposed to more light than it has ever experienced, which causes sunburn.
The foliage will turn pink as a result of this sunburn. Succulents that have been kept indoors for months and are suddenly moved to the outdoor garden frequently experience this. The succulent plant may experience some shock when exposed to the bright light on its leaves.
If your succulent is positioned too close to a glass window, the glass will magnify the sun’s rays before they reach the leaf of the plant, which is another way it can get sunburned. Plants placed in windows facing the south frequently do this.
Remedy
Transfer your plant to a new location where it may only receive indirect light for six hours each day, such as a patio or one foot away from a west-facing window, to correct this discolouration brought on by too much sunlight.
If you intend to move an indoor plant to your outside garden, acclimate the plant gradually by progressively increasing the amount of time it spends in the light each day. Up until the plant has completely adapted to its new environment, keep up the acclimatization.
If you give your succulent a few days to adjust to increasing amounts of light, it won’t suffer from sun damage and you should be able to keep its green hue.
Not enough light
When a succulent receives less light than it requires daily, this might also cause it to turn pink.
When certain succulent plants are under stress from insufficient light, such as some cacti, anthocyanins are produced. The pinkish color of the plant’s leaves is caused by the combination of the purple pigment anthocyanin and the green pigment chlorophyll.
Keep in mind that succulents require sunshine to survive and operate normally. They cannot undertake photosynthesis without it, which prevents them from growing their own food.
The yellowing of a succulent that isn’t getting enough light can be easily remedied. Simply move it to a location where it will have access to the constant, brilliant indirect light that it requires.
Overwatering
Your succulent is receiving too much water, which is another cause of its pinking.
This might be the case if you water it more frequently than you should or if you give it more water than it requires each time. In any case, this causes overwatering, which causes root rot.
The condition known as root rot is brought on by a plant’s roots spending an extended period of time drowning in damp soil. The decaying dead roots will start to attract opportunistic infections like fungus and bacteria. As a result of these diseases, the rot will spread more quickly and eventually kill the entire plant.
The leaves on your plant may become yellow, pink, red, or brown and become soft and mushy to the touch as a sign that it is overwatered.
The wrong potting mix might also contribute to overwatering. Succulents want potting soil that is porous and airy so that water and air may easily pass through it. Additionally, if the pot you use doesn’t have drainage holes at the bottom, this can also result in an accumulation of water that can cause root rot.
You must immediately stop watering your succulent if you notice that it may be turning pink from overwatering.
Take the plant out of the pot, then wash the roots to remove as much of the old soil as you can. So as not to harm the delicate roots, go slowly. Examine all of the roots, and using sterile scissors, remove any areas that have gone brown or black.
After that, place the plant on a clean piece of paper towel and let it air dry for a few hours.
Prepare a fresh container with drainage holes at the bottom, and fill it two-thirds with new succulent-specific potting soil.
After putting the plant in the middle of the dirt, add more potting soil to fill the container up. Gently tap the ground close to the plant’s roots.
The soil won’t need any additional moisture; it’s already damp. Before watering the newly potted plant, wait at least a week.
Check the top two inches of soil with your finger before watering your plant to prevent overwatering. If the soil is humid, wait one or two days before examining it again. If the soil is dry, water it.
Underwatering
Although it may not be as harmful as overwatering, underwatering can nonetheless result in your succulent turning pink.
A succulent’s foliage will first turn pink, then purple, and then turn brown if it does not receive enough water. The leaves will wrinkle and get crispy as they dry out.
Fortunately, a succulent that has been underwater is much simpler to cure than one that has been overwatered.
To restore the succulent to health, you will need to wet and dry it. Water the plant five times with water that is equal to the volume of the pot when the soil is completely dry.
After watering the soil, wait until the top two inches feel dry to the touch before watering it again.
A succulent only has to be watered on a regular basis when the soil is dry. By doing this, you can prevent your plant from being both overwatered and underwatered.
Changes in temperature
Your succulent may also be becoming pink since you are subjecting it to temperatures that are far higher than they are accustomed to.
This might be because the plant is in direct, unfiltered sunlight, it’s next to a radiator, or it’s located where a heater is blowing heated air directly at it.
The plant will release anthocyanin as a result of the heat stress, which is, as previously said, a purplish pigment that takes on a pink hue when combined with chlorophyll in the plant.
Your succulent may have tissue damage as a result of excessive heat, which may impair photosynthesis and produce more discoloration.
The plant will also experience temperature stress and develop pink discolouration if it is placed in an area where it will be hit by cold air, such as next to an air conditioner or a door or window that allows in cold drafts.
Simply move your plant to a location where it won’t be exposed to extremes of heat or cold to correct any discolouration brought on by temperature variations.
A room that is between 70 and 80 degrees Fahrenheit is the ideal temperature for keeping an indoor succulent.
