Why Is Christmas Cactus Dropping Leaves

Given how simple it is to cultivate Christmas cactus, you are understandably puzzled and worried about the health of your plant if you notice leaves falling off. There are several reasons, though it isn’t always clear what causes Christmas cactus leaves to fall. You might wonder why Christmas cacti lose their foliage. Learn more by reading on.

Why do the leaves on my Christmas cactus continually dropping off?

The Christmas Cactus (Schlumbergera) is one of my favorite plants for a variety of reasons, including their beauty, the fact that they bloom over the holidays when most other plants aren’t at their best, and the fact that they continue to bloom for decades. Therefore, it makes sense that the sight of a Christmas Cactus shedding leaves would be alarming.

Overwatering or other situations that result in damp soil are the most frequent causes of Christmas cactus leaf drop. In addition to harming the rest of the plant, this results in root rot. Leaf drop can also be a result of ill-draining soil, temperature stress, excessive fertilization, poor lighting, or pests.

How often should my Christmas cactus 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.

How can you tell if a Christmas cactus is overwatered?

Overwatered stems will appear mushy and limp. If the roots are getting dark and mushy, remove the plant from the ground and check them. If so, the plant is badly overwatered and has root rot.

Do you water a Christmas cactus from the top or bottom?

A smart approach to prevent water from sitting on the stem and rotting is to water your plant from the bottom.

Pick a pot with lots of drainage holes if you want to do this. For 30 minutes, place the pot in a bowl of water. Remove any extra water, then reposition the plant.

Temperature problems

Holiday cacti may experience shock and lose their leaves in response to significant temperature swings. Always keep them inside during the winter and keep them away from drafts.

Is Epsom salt good for Christmas cactus?

Epsom salts give your plant magnesium, which Christmas cacti love. One teaspoon can be added to one gallon of water. Use without fertilizer To prevent fertilizer burn, only use one or the other at once.

Should I repot my Christmas cactus?

Your holiday cactus has to be repotted every year or two, just after the blooms have finished. Pick a pot that is 2 inches wider across!

Your plant might benefit from new nutrients in new soil rather than needing a bigger pot. Pull it out of the pot gently, remove as much soil as you can, and then repot it in the same pot with new soil.

How can you determine if my Christmas cactus received too much water?

Any cactus that has been left to sit in a saucer of water is probably less healthy. The Christmas cactus plant will manifest clear signs of suffering if it is overwatered. To avoid moisture gnats and preserve the roots from decaying, you should always dump the extra water from the saucer if it hasn’t dried in a day.

One of the first signs of overwatering on a Christmas cactus are limp leaves that begin to fall off, just in case you forgot to do this. The stems and branches will thereafter become mushy and spongy. In severe situations, the stem can entirely rot off and the symptoms will include a bad smell.

Prevention is easy to do. To avoid overwatering Christmas cactus, use a soil moisture meter.

How can a Christmas cactus be revived?

Repot the Christmas cactus into new soil when it is extremely limp and the earth is wet. As much soil as you can gently remove from the pot after removing the weak Christmas cactus from it. By repotting your Christmas cactus with your own homemade soil, you can prevent future issues. Use high-quality potting soil in a 2:1 ratio with sand or vermiculite to ensure precise drainage.

Repotting a weak Christmas cactus might be the answer, even if the soil is dry. Even though the plant prefers to be tucked away in its pot, switching to a little larger pot with new soil every few years will help you prevent Christmas cactus issues.

What kind of plant are overwatered cactus?

The obvious indicators of an overwatered cactus caused by a fungus in the soil include black or brown blotches and mushy stems. It’s time to carefully chop them off with a knife if you experience any of these bodily symptoms. Use a sterilized knife while handling a rotting plant to prevent the spread of the infection.

You will have to exert more effort if the damage is severe. Essentially, what you’ll be doing is multiplying the portions of your plant that are still alive. Wear nitrile gloves to protect your hands from the cactus’ spines while you chop off the rotting sections, and exercise extreme caution when handling the plant. After cutting out the damaged areas, let your cuttings air dry for a few days, or around a week.

Where should a Christmas cactus be placed?

Holiday cacti may be bought pretty much anywhere that sells plants, from the grocery store to the flower shop, and are incredibly popular gifts during the winter and spring. Holiday cactus are attractive and attract both seasoned and newcomer houseplant aficionados with their succulent foliage and colorful, multicolored blossoms. They frequently pass down from one family to the next and, given adequate care, can live for many years.

Christmas cactus (Schlumbergera x buckleyi), Thanksgiving cactus (Schlumbergera truncata), and Easter cactus (Rhipsalidopsis gaertneri) are three separate varieties that are commonly offered at retail outlets depending on the season “All of them are frequently referred to as Christmas cacti. Due of their comparable maintenance requirements, it is simpler to refer to all three as holiday cacti.

Despite “Holiday cacti require very different maintenance than their desert-dwelling siblings because it’s in their name. Holiday cactus are epiphytes that naturally grow in the shaded limbs of trees in Brazil’s tropical rainforests. Epiphytes are plants that grow on other plants rather than in the ground and obtain their nutrients and moisture from the rain and the atmosphere.

As a result, unlike other cacti, holiday cactus are less tolerant to prolonged drought. Once the potting soil seems dry to the touch, they should be watered, allowing extra water to freely drain from the bottom of the container. Do not allow plants to sit in standing water as this can cause the soil to become flooded. Root rot can develop as a result of ongoing exposure to excessively moist soil, particularly during the winter.

Holiday cacti’s watering requirements vary depending on a variety of elements, including the type of potting soil used, the size of the container, the amount of sunlight the plant receives, and the temperature outside. Making ensuring the plant is in the proper area and only watering when the soil mixture is dry are the keys to maintaining a healthy plant.

Holiday cacti thrive in partial shade, such as an east or west facing window, with temperatures between 70 and 80 degrees Fahrenheit. Lack of light can limit growth and make the soil mix dry too slowly, while too much harsh sunlight, especially in the summer, can burn the foliage. When in doubt, it is better to water your plants too much than too little.
