Christmas Cactus

Christmas cactus (Schlumbergera x buckleyi) is a popular cactus grown for its colorful cerise flowers. It is often confused with the Thanksgiving, or crab, cactus (Schlumbergera torreyi), which blooms at different times of year and has a slightly different shape to its leaves.

Like many tropical houseplants, christmas cactus needs a well-draining soil. It thrives in temperatures between 60 and 70 degrees, and does best in indirect sunlight rather than direct light from a window. It is also not a fan of drafts, so keep it away from heat vents and fireplaces.

To encourage reblooming, spruce up your christmas cactus in late spring by removing old, brown leaves and pinching back the stems. This will force the plant to branch out and grow more of its distinctive, flat segments. It’s safe to prune after the plant blooms, which last up to six weeks.

In its natural habitat, christmas cactus goes into a period of dormancy in the autumn as temperatures drop and days shorten. Mimicking this environmental trigger is the key to a successful bloom cycle.

As the weather turns cooler, bring your christmas cactus inside and place it in a dark room with no light of any kind. Start counting back eight weeks from the date you want it to begin its reblooming cycle, and then gradually increase the amount of light each day. Begin watering and fertilizing regularly, but do not overwater or move the cactus around too much.
