Can You Grow Christmas Cactus Outdoors?
Introduction
Christmas cactus, also known as Schlumbergera bridgesii, is a popular holiday plant known for its vibrant blooms. But can you grow it outdoors? The answer is yes, but only if you live in a warm climate.
Growing Conditions
Christmas cactus is a tropical plant that thrives in warm, humid environments. It prefers bright, indirect light, such as what it would receive under the shade of trees in its natural habitat. The ideal temperature range for Christmas cactus is between 65-80°F (18-27°C).
USDA Plant Hardiness Zones
Christmas cactus is not cold hardy, meaning it cannot tolerate temperatures below 50°F (10°C). Therefore, it can only be grown outdoors year-round in USDA plant hardiness zones 9 and above. These zones are typically located in the southern United States and other warm regions of the world.
Outdoor Care
If you live in a cooler climate, you can still enjoy Christmas cactus outdoors during the warmer months. Simply plant it in a container or hanging basket so you can bring it indoors when temperatures drop below 50°F (10°C).
Watering
Water your Christmas cactus when the soil is dry to the touch, but not bone dry. Avoid overwatering, especially during the winter months, as soggy soil can lead to root rot.
Fertilizing
Fertilize your Christmas cactus monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength.
Light
Christmas cactus prefers bright, indirect light. In warmer climates, a location in light shade or early morning sun is ideal. In cooler climates, you may need to provide artificial light indoors during the winter months.
Temperature
Keep your Christmas cactus in a warm location with temperatures between 65-80°F (18-27°C). Avoid exposing it to sudden changes in temperature, as this can cause the buds to drop.
Pests
Christmas cactus is susceptible to a variety of pests, including mealybugs, aphids, scale, and mites. Inspect your plant regularly for pests and treat them promptly with an insecticidal soap spray or neem oil.
Pruning
Trim your Christmas cactus in early summer by removing two or three segments from each stem. This will encourage full, bushy growth and promote flowering.
