Long-lived plants like the Christmas cactus are frequently passed down from one generation to the next. The cactus will thrive with deep, infrequent watering, so you may essentially ignore it. A Christmas cactus plant, on the other hand, will perish from root rot if it is overwatered and may end up on the compost pile. To avert this calamity, quick, deliberate action is needed to save a Christmas cactus that has become overwatered.
Christmas cacti are native to southeast Brazil’s coastal mountains. They are all members of the Schlumbergera genus, which is home to all of the Christmas cactus. Christmas cactus is not the typical drought-tolerant desert species because it receives abundant rain for a large portion of the year in its native habitat. After giving them a good soak, the soil should be allowed to almost completely dry off. They must be maintained reasonably moist while flowering, although Christmas cactus should not receive an excessive amount of water.
How frequently should Christmas cacti be watered?
Christmas cacti are highly common indoor plants, and for good reason too! They produce vibrant, tubular flowers that are pink or purple in hue when they bloom. They are a superb plant because of their lovely blossoms, lengthy bloom period, and simple maintenance needs. Someone in your family most likely owns a Christmas cactus!
About Christmas Cacti
The Christmas cactus (Schlumbergera x buckleyi) and its cousins don’t exist in hot, arid conditions like deserts or plains, in contrast to other cacti. These epiphytic succulents, which grow on tree branches and take in the high humidity, dappled sunlight, and moderate temperatures, are actually endemic to the tropical rainforests of southern Brazil.
Bottom line: Don’t handle a Christmas cactus like a typical succulent or cactus. They are unable to withstand the same kind of hot, dry weather that other cactus can. These cacti require more frequent watering than most succulents, but you also need to be careful not to overwater them. (See the care guidelines in more detail below.)
Thanksgiving, Easter, or Christmas Cactus?
The Easter cactus (S. gaertneri), Thanksgiving cactus (S. truncata), and Christmas cactus are the three main varieties of “holiday cacti” that are available (S. x buckleyi). The holiday that each cactus is named after often sees the most blooming. Thanksgiving cacti, which often bloom from November to February and hence go unrecognized as Christmas cacti, make up the majority of “Christmas cacti” sold nowadays. See our post on the several Christmas cacti species and how to distinguish them for more information.
Note: Because it’s the most widely used term and it applies to all three of these species, we’ll refer to all three of them on this page as “Christmas cactus” for simplicity’s sake.
Potting Christmas Cacti
- Choose a pot with a drainage hole on the bottom if you’re choosing one for a Christmas cactus. This prevents the soil from getting overly saturated.
- Most succulent-specific potting mixtures work well for Christmas cacti growth. It’s crucial that your potting soil drains properly.
Where to Put a Christmas Cactus
- Plants should be kept in indirect light that is bright. The best location has an east-facing window or a well-lit bathroom. The delicate leaves might be bleached by too much direct sunshine.
- It is preferable to have a daytime temperature of 70F (21C) and an evening temperature of 60–65F (15–18C).
- Christmas cacti do well in a more humid climate, so keeping them in a well-lit bathroom or kitchen is a smart idea.
- Christmas cacti can be kept in a shady area of the garden or on an unheated porch during the summer until the temperature drops below 50F. (10C). Keep them away from the sun’s rays outside.
How to Care for Christmas Cacti
- Water your plants every two to three weeks, but only when the top third of the soil feels dry to the touch. If the plant is in 6 inches of soil, for instance, water when the top 2 inches of soil feel dry. (Check with your finger!)
- When the soil is completely dry, wet it until water seeps through the drainage holes in the pot. To collect the water, put a tray underneath the pot. To prevent the pot from sitting in water, remove any extra water on the tray after 10 to 15 minutes.
- While the plant is in bloom, it’s very crucial to water thoroughly.
- Feed your indoor plants with a balanced houseplant fertilizer every two weeks from spring through early fall. Feed the cactus once a month in the fall and winter to promote fruitful blooming.
- To promote branching and more flowers, prune plants in the late spring. Simply cut a portion of each stem off; the plant will grow new branches from the incision.
- If desired, plant the cut pieces in potting soil that is only gently damp; they will easily root after a few weeks and make wonderful Christmas gifts!
How to Get Your Christmas Cactus to Bloom
The longer evenings and chilly weather of fall are what cause Christmas cacti and its relatives to bloom. The three major varieties of holiday cacti typically bloom on the following schedule:
- Thanksgiving cactus typically produce flowers from late October through mid-winter, making them the earliest and longest bloomers.
- Christmas cacti often bloom in the early to midwinter months.
- Easter cacti flower around the middle of spring through late winter.
If your cactus isn’t flowering, it can be getting too much light or being exposed to too much heat. Here are some suggestions to help you get blooms from yours!
- For a minimum of six weeks, the nights must be at least 14 hours long and the days between 8 and 10 hours. You might need to cover your cactus or relocate it to an area that is exposed to the natural light cycle if you have powerful interior lighting that is on at night.
- When the plant is kept at temps between 50 and 60F, flower buds form best (10 and 15C).
- By subjecting the plant to temps around 45F (7C) for a number of nights in a succession, you can jumpstart the budding process.
- While the plant is in bloom, be sure to water it consistently. The plant may lose its buds if it dries out too much.
- Don’t worry if the cactus loses its buds one winter; the following year it should bloom.
The three primary varieties of “holiday cacti” are as follows:
- Often mistaken for Christmas cacti, Thanksgiving cacti (Schlumbergera truncata) bloom from late October to mid-winter.
- Christmas cacti (S. x buckleyi) flower in the early to midwinter months.
- Late winter to mid-spring is the blooming period for Easter cacti (S. gaertneri).
- Make sure to water your Christmas cactus frequently and keep it cool when the buds on the plant appear ready to open.
- The optimum time to propagate cuttings is late spring when most holiday cacti start to grow after their winter hibernation.
Blossom loss: Your Christmas cactus will probably lose its blossoms if it experiences any kind of stress. As mentioned in the plant care section above, this could be caused by the amount of light or a sudden shift in temperature. Make sure your soil doesn’t become overly dry while buds are developing.
The plant could be vulnerable to mealy bugs and root rot if overwatered. If you experience issues, remove the affected sections and repot the plant in fresh soil.
Do Christmas cacti overwater themselves?
Christmas cactus is generally quite understanding. It asks little in return and blooms freely throughout the winter. However, according to Dammann’s Garden Company, it is prone to a number of ailments brought on by overwatering.
The Christmas cactus is a succulent and can resist drought, but it cannot tolerate excess moisture or overwatering. Depending on the extent of the damage, your Christmas cactus may or may not live if you overwatered it. To replace the plant, you might be able to take some cuttings and root them.
Why are my Christmas cactus’ limp leaves?
Lack of water or much sunlight can occasionally result in wilted or weak Christmas cacti. Start by giving the wilting Christmas cactus a small amount of water if you haven’t been watering it. Every few days, continue to water carefully until the soil is barely damp.
Christmas cactus issues can also result from excessively damp soil. The Christmas cactus cannot tolerate wet roots since it is an epiphyte in its natural habitat on the ground of tropical forests, where it takes moisture and nutrients from the air. The roots of Christmas cacti can become excessively wet and floppy because to poor drainage.
Move your wilted or limp Christmas cactus to a location with more shade, especially in the afternoon, if the leaves look dried or burned.
An ideal Christmas cactus moisture level
Remember that Christmas cactus plants prefer constantly moister soil than the majority of other succulents do. Typically, a Christmas cactus needs water when the top inch or two of soil are dry. Fill the pot saucer with pebbles and add water to just below the tops of the pebbles (the pot shouldn’t be sitting directly in water) to help improve the humidity surrounding the plant. As the water evaporation increases, the air will become more humid. (See below for advice on watering when attempting to encourage your Christmas cactus to rebloom.)
Which is better for watering: the top or the bottom?
To ensure that the water reaches the Christmas cactus’ roots, irrigate it from the bottom up. Continue adding water to the soil until it begins to seep through the pot’s openings. It hydrates the ground.
Ensure that there is no standing water beneath the pot once the soil has been thoroughly moistened. Never leave excess water in the planter; you don’t want mold, root rot, or insects laying eggs there. If the water is fully separate from the pot and is in a tray underneath the pot, that’s acceptable.
Mist the Leaves
You can sprinkle the leaves with water in a spray bottle to keep them as healthy as possible. When watering the plant, misting the leaves only once will be sufficient to provide appropriate hydration.
Are Christmas cacti misted well?
Contrary to what its name might imply, Christmas cacti can survive well into the following year. In fact, with a little care and our guidance, they can live for up to 20 years.
Christmas Cacti need cooler temperatures.
Leaving Christmas cacti in a space that is between 60 and 70 degrees Fahrenheit will cause them to bloom more fully and sooner. Keep them away from radiators, fireplaces, and warm windowsills, especially during the winter.
While they don’t need the heat of the sun, they do need its light.
The hard part comes at this point. A Christmas cactus needs lots of sunlight but cannot be kept in direct sunlight as it will dry out. So what should a cactus aficionado do? Your best option is to leave it in a part of your home that is shaded (or outdoors once summer arrives) and rotate it occasionally.
Just like you and I, Christmas cacti need their rest.
Your cactus needs between 1215 hours of uninterrupted darkness per day if its buds haven’t yet set. Cacti only require lots of light once their buds have fully developed.
You should be misting, not watering, every day.
Your cactus will die if you overwater it. But that doesn’t mean they never experience thirst. You should mist your cactus every day rather than watering it like you would a regular plant. You only need a few sprays from a spray bottle to maintain your cactus’ happiness. Only when the soil at the base of the plant feels entirely dry to the touch should you water it.
Christmas cacti need nutrient-rich soil.
Christmas cacti are strong plants that can endure harsher environments, although well-drained soil that has some organic matter is preferable for them. While organic soil is always available to purchase, you can also use your cacti as a little compost and add organic waste that you would typically discard.
How may an overwatered Christmas cactus be saved?
Don’t worry if your plant starts to show symptoms because overwatering is one of the common Christmas cactus issues. Move swiftly to remove any standing water, then take the plant carefully out of its container. Eliminate any stems that have begun to soften. Rinse the roots to get rid of any fungus that may have developed, and then leave them to air dry on the counter for a day.
The following morning, repot the plant and let it a few days to dry out before starting a normal watering schedule. The plant should recover if you caught it in time. As the Christmas cactus may not be able to endure another disease, use your soil meter to prevent any other issues.
Just in Case!
One of the simplest plants from which to take cuttings is the Christmas cactus. Pick healthy stems and start the roots by putting them in a glass of water, perlite, or vermiculite. For better drainage, put them in a mixture of one part sand, one part potting soil, and one part orchid bark.
To encourage the evaporation of extra moisture, use an unglazed pot. By doing this, you can be sure that you won’t ever have to worry about trying to save an overwatered Christmas cactus again. Up until a few weeks prior to the blossoming season, provide full sun. Then, to encourage blossoming, give it a minimum of 14 hours of darkness each day. For this time, stop watering as well. You’ll soon have a festive cactus to add color to your celebrations and share with friends and family.
How can you determine if something is under or overwatered?
Since the signs of underwatering and overwatering sometimes resemble one another, we’re here to explain what each sign might signify. Check your plant for the following indicators of water stress to determine which you are now experiencing.
Wilting: In order to distinguish between overwatering and underwatering, check the soil around the plant. Overwatering occurs when the soil is wet; underwatering occurs when the soil is dry.
Another symptom that can go either way is browning edges.
Determine which by touching the leaf that is beginning to brown; if it feels light and crispy, it has been submerged. It is overwatered if it seems limp and soft.
Yellowing foliage: Yellow leaves are a sign of overwatering and are typically accompanied by new growth dying off. However, lower leaves that are yellow and curled may also be a symptom of underwatering. To determine which one it might be, check the soil for dampness.
Bad smell coming from the earth: Bad odors from the soil may be a sign that the roots have been overwatered and are decomposing.
Underwatering
A plant that has been submerged may first turn purple before drying to a brittle, dead brown. Water is as important as sunlight, and photosynthesis is prevented by insufficient moisture. Additionally, an extremely dry atmosphere may stress the plant.
Place a shallow pan of water in front of a heat register if you notice that your house gets dry during the winter and clean it anytime it gets dry. Water evaporation causes the air to become more humid and wet.
You may also use a shallow pan with a bed of gravel and your potted cactus as an evaporation method. The gravel should be covered with water.
Additionally, you can group indoor plants and water them regularly to simulate the tropical dampness that rainforest cactus are used to.
Overwatering
On the other hand, over watering can turn leaves yellow and, in rare instances, purple to brown before becoming mushy. Extreme overwatering or underwatering may reach the roots.
Air is yet another component of photosynthesis. The production of food is deadly threatened by the inability of soggy roots to breathe.
Use a pot with a large enough drainage hole to avoid stress caused by dampness. Pick a loose, well-draining potting medium.
