The main types of holiday cacti are Thanksgiving cactus (Schlumbergera truncata), Christmas cactus (Schlumbergera x buckleyi), and Easter cactus (Hatiora gaertneri)!
The Thanksgiving cactus typically blooms early in the holiday season, from Thanksgiving through Christmas. The leaf margins on this cactus have two to four saw-toothed projections pointing upward on the sides of the stem. This cactus comes in several flower colors, ranging from red and lavender to salmon-orange and white.
The Christmas cactus blooms later in the season, from Christmas through March. The leaf margins usually have four rounded scallops along the edges of the stem. The flower colors are usually red and white.
Although not a winter holiday plant, the Easter cactus is a great plant to give in the spring. The Easter cactus generally blooms from March to May. It may bloom again in the fall. Flowers are usually pink or red. Leaf margins are smoother than the other seasonal cacti and have brownish, hair-like bristles at their tips.
Caring for holiday cacti is not difficult. They will bloom if kept in cooler parts of the house, away from heating vents. A coarse soil mix (high humus, sharp sand) that provides drainage is important. Keep the soil medium moist, not wet. Holiday cacti can easily be overwatered and are susceptible to root rot.
For repeat flowering, place cacti in a room with cool temperatures (60 to 65 degrees), stop fertilizing, allow the soil to become dry between waterings, and provide 12 hours of uninterrupted darkness every night for 5 to 6 weeks.
Once flower buds appear, move the plants to a bright-light location and resume normal watering and fertilizing. Maintain cool temperatures (60 to 70 degrees) to avoid bud drop.
Cacti are easy to propagate by making cuttings of stem sections. Propagation works best when done in early spring or summer.
