Orchid Cactus Care

Botanical Name: Epiphyllum spp.

Big, cup-shaped blooms in gorgeous colors make orchid cactus a joy to grow. Show it off in a hanging basket and allow the long stems to cascade over the pot.

Orchid cactus stems are broad and flat with serrated edges. They'll grow to 2 ft (60 cm) long, and about 2 in (5 cm) wide. Not very showy, but you can count on them to burst into bloom every spring.

Flowers emerge at the ends of the stems, and can be 4-8 in (10-20 cm) wide. Most Epiphyllum grown today are hybrids and may be pink, red, white, yellow, orange, purple or bicolored. Give your tropical cactus plenty of light and you'll enjoy months of blooms.


You won't need to prune unless you want to control its size. The best time to prune it back is shortly after it stops flowering. Use sharp, clean pruning shears to prevent tearing the stems.

How to Make Orchid Cactus Bloom

Growing this flowering cactus is easy, but a few things you can do will help it to bloom:

  • Give it a winter rest. A cool, dry rest for about 8-10 weeks in winter are needed for the plant to set buds. Water sparingly and stop fertilizing during this time.
  • Shed some light. Keep your orchid cactus in bright, indirect light year-round. If you move it outdoors for the summer, keep the plant shaded from direct sunlight.
  • Feed it. High-phosphorus fertilizer will encourage more blooms. Start feeding in early spring and continue through fall.
  • Leave it alone. Once buds appear, keep the plant in the same location. Changes in light and temperature by moving it around will cause it to drop its buds and flowers. Also keep it away from drafty areas like doorways and heat/AC vents.

Repot every 2-3 years, moving up to a pot 1 size larger. Orchid cactus prefers to be slightly pot-bound and blooms best this way. Wait till early spring to repot -- never while it's blooming, which will cause its buds and blooms to drop.

Buying tips: The true orchid cactus is still commonly known as Epiphyllum, but has been renamed NopalxochiaMany hybrids and cultivars are available. Well-known for their night-blooming flowers, newer hybrids have been developed for daytime blooms.

Epiphyllum oxypetalum (shown here) is among the most popular species of this genus. It bears white, fragrant flowers that bloom for one night only -- then wither by morning. If you sneak up on it during the night, you'll catch it in full bloom.

Orchid Cactus Care Tips

Origin: Central America hybrids

Height: Trails to 2 ft (60 cm)

Light: Bright light, but no direct sunlight

Water: Keep the soil moist spring through fall, while plant is growing. In winter, water sparingly until new growth begins in spring. Never allow it to dry out. Shriveled, limp stems are a sign the soil is too dry.

Humidity: Moderate indoor (about 40-50% relative humidity). Stand the pot on a dish of wet pebbles to boost humidity, if necessary.

Temperature: Average room temperatures 65-75°F/18-24°C. To set flower buds, the plant needs 8-10 weeks of cool 60-65°F/16-18°C days and 45-55°F/7-13°C nights in winter.

Soil: Mix 1 part peat moss-based potting mix and 1 part perlite

Fertilizer: Feed every 2 weeks from early spring through fall with a high-phosphorus water-soluble fertilizer. Don't feed during the winter.

Propagation: Detach 4-6 in (10-15 cm) stem sections in spring, allow cut to dry (callous) for a few days, then place cut end upright in lightly moist potting mix. Keep cuttings at room temperature (65-75°F/18-24°C). Stem cuttings root easily in about 4-6 weeks.
