Botanical Name: Schlumbergera bridgesii
Good Christmas cactus care will ensure beautiful blooms in time for the holidays.
This tropical cactus does not exist in the wild. It is a hybrid of Schlumbergera truncata and Schlumbergera russelliana that grow as epiphytes in the rain forests of South America.
Schlumbergera bridgesii has dark-green flattened stems composed of segments joined in a scalloped pattern. Flowers appear at the tips of the stems and are available in shades of pink, red, purple, yellow, and white. Newer cultivars bring together two colors, offering some exciting new combinations.
After your Christmas Cactus is through flowering for the season, it needs about a one-month rest. Water sparingly and stop fertilizing until new growth begins in spring.
Regular pruning will encourage the plant to branch out where the stem was cut, creating a fuller plant. Spring is the best time to prune it back, when it begins actively growing again.
Pruning tip: Use sharp, clean pruning shears to prevent tearing the stems. Cut a stem off between segments (the place where they're joined together by a midrib).
Growing this plant is easy, but there are a few things you should do to make it bloom before the holidays.
Repotting Christmas cactus plant is usually only necessary every 2 to 3 years. It prefers to be slightly pot-bound and blooms best this way. Wait till spring or early summer to repot -- never while it's blooming.
Origin: Hybrid with parents native to Brazil
Height: To 2 ft (60 cm)
Light: Bright indirect light
Water: Keep the soil moist, but not soggy while plant is growing. After flowering, water sparingly until new growth begins in spring.
Humidity: Moderate -- about 50-60% relative humidity. Stand the pot on a dish of wet pebbles.
Temperature: To set flower buds, the plant needs cool 60-65°F/16-18°C days and 45-55°F/7-13°C nights. Once buds set, 70-75°F/21-24°C days and 60-70°F/16-21°C nights.
Soil: Well-drained potting medium is essential. Mix 1 part potting mix and 1 part fine-grade fir bark.
Fertilizer: Feed every 2 weeks with a balanced liquid fertilizer diluted by half. After blooms have dropped, stop fertilizing for a month.
Propagation: Take stem segments in spring and place upright in moist perlite.
These tropical cactus plants need cool 45-55° nights for buds to develop.
They also do best with moderate humidity. Check out these tips for raising the humidity for your house plants.
More than 200 cultivars exist. 'Christmas Flame' is golden yellow...'Lavender Beauty' is purple and white... and snowy 'White Christmas' are just a few. With so many beautiful colors to choose from, why buy just one?
Although this holiday-blooming cactus is a hybrid, its origins are in the tropical rainforests, where Schlumbergera make their home as epiphytes, growing on tree branches.
Epiphyte comes from the Greek words epi meaning upon and phyton meaning plant.
