The Mistletoe Cactus (Rhipsalis baccifera) is a popular houseplant known for its long, slender, segmented stems. This epiphytic cactus is often grown in hanging baskets, where its trailing habit can be fully appreciated.
Getting to Know the Mistletoe Cactus
Rhipsalis baccifera is an epiphytic cactus that naturally grows on other plants in tropical rainforests. This allows it to absorb moisture and nutrients from the air and debris. Originating from Central and South America, the Caribbean, Africa, and Sri Lanka, it is the only cactus species found naturally outside the Americas. Its long, pendulous stems, which can reach several feet, resemble mistletoe, giving the plant its common name.
Essential Care for Mistletoe Cactus
Light
The Mistletoe Cactus thrives in bright, indirect light, similar to dappled sunlight under a forest canopy. While it tolerates some shade, avoid direct, harsh sunlight as it can scorch stems. Place it near an east or north-facing window, or a few feet from a south or west-facing window where light is diffused.
Watering
Unlike desert cacti, Rhipsalis baccifera needs consistent moisture due to its tropical origins. Use the “soak and dry” method, allowing the top inch or two (2-5 cm) of soil to dry completely between waterings. Overwatering causes root rot, so proper drainage is important. Reduce watering frequency during cooler winter months when growth slows.
Soil and Potting
A well-draining, airy soil mix is essential for the Mistletoe Cactus, replicating its epiphytic growing conditions. Combine equal parts peat moss, perlite, and orchid bark, or use a cactus/succulent mix with added perlite or pumice for drainage. This plant prefers to be slightly root-bound, needing repotting only every 2-3 years or when it outgrows its container. When repotting, select a pot 1-2 inches larger in diameter.
Temperature and Humidity
Mistletoe Cactus prefers warm temperatures, ideally 60-80°F (15-27°C). Protect it from temperatures below 50°F (10°C), as it is not frost-tolerant. Higher humidity (50-70%) benefits this plant, reflecting its rainforest origin. Increase humidity by grouping plants, using a pebble tray, or employing a room humidifier. Misting also contributes to local humidity.
Fertilizing
During its active growing season (spring and summer), Mistletoe Cactus benefits from regular fertilization. Use a balanced liquid fertilizer diluted to half strength to prevent over-fertilization. Fertilize every 4-6 weeks during this period. Reduce or stop fertilizing in fall and winter when growth slows.
Displaying and Shaping Your Hanging Mistletoe Cactus
The Mistletoe Cactus’s cascading growth makes it excellent for hanging displays. Use macrame hangers or decorative pots with ample drainage. Terracotta or clay pots are favored for better air circulation and moisture evaporation, benefiting root health. When hanging, ensure the plant receives bright, indirect light without harsh direct sun.
Light pruning helps maintain the desired length and fullness. Trimming stems encourages bushier growth, creating a more robust appearance. Pruning also provides healthy stem sections suitable for propagation.
Growing New Mistletoe Cactus Plants
Propagating Rhipsalis baccifera is straightforward, primarily through stem cuttings. Select healthy stem sections at least a few inches long. After cutting, allow the severed end to dry and form a callus for a few days to a week; this prevents rot when planted.
Once callused, root the cutting in a well-draining cactus or succulent potting mix. Insert the callused end into the soil for stability. Keep the soil lightly moist but not soggy, and place the pot in a warm location with indirect sunlight. Rooting takes a few weeks.
