The Christmas cactus (Schlumbergera spp.) is a popular holiday plant known for its vivid blooms and long lifespan when properly cared for. Despite its name, this plant isn’t a true cactus and has different care needs than desert varieties. Native to the rainforests of Brazil, the Christmas cactus thrives in conditions that mimic its natural habitat: filtered light, moderate moisture, and high humidity.
While generally low-maintenance, many plant owners unknowingly make mistakes that can lead to stunted growth, dropped buds, or a lack of blooms altogether. Here are the most common Christmas cactus care mistakes—and how to avoid them.
1. Overwatering
One of the most frequent problems with Christmas cactus care is overwatering. Unlike desert cacti, this plant doesn’t like to dry out completely, but soggy soil can lead to root rot and fungal issues.
Avoid it by:
Letting the top inch of soil dry out between waterings.
Using a well-draining potting mix.
Ensuring the pot has drainage holes.
Water less frequently in the fall and winter, when the plant’s growth slows.
2. Using the Wrong Soil
Many assume that cactus soil is ideal for Christmas cactus, but this is a common misconception. Christmas cacti prefer a rich, slightly acidic soil that retains some moisture while still draining well.
What to use:
A mix of potting soil with added perlite, coconut coir, or orchid bark works well.
Avoid dense, heavy soils that stay wet for too long.
3. Placing in Direct Sunlight
Although they enjoy bright conditions, Christmas cacti can suffer in direct sunlight. Too much sun can cause the leaves to turn red or yellow and may result in scorched foliage.
Solution:
Place the plant near an east- or north-facing window with indirect light.
Use sheer curtains to diffuse light in sunnier locations.
