Mistletoe Cactus - Care Sheet
Rhipsalis baccifera
Overview
The Mistletoe Cactus, scientifically known as Rhipsalis baccifera, is a unique and fascinating epiphytic cactus native to tropical and subtropical regions of Central and South America, the Caribbean, Florida, as well as parts of Africa and Sri Lanka. Unlike most cacti, it naturally grows in humid forest environments, often as a trailing or hanging plant on trees. It features slender, pendulous, green or pale green cylindrical stems that can grow quite long, making it a popular choice for hanging baskets indoors. This cactus produces small, white or greenish-white flowers in late winter to early spring, followed by mistletoe-like white or pink berries. It is generally considered a beginner-friendly houseplant due to its low maintenance requirements and adaptability to indoor conditions.Quick Facts

Light
Mistletoe Cactus thrives in bright, indirect light. Avoid direct sunlight, especially harsh afternoon rays, as they can scorch the delicate stems. A spot near an east- or north-facing window is ideal. If the plant receives too little light, growth may become leggy and sparse, while too much direct sun may cause yellowing or browning of the stems.Water
This cactus prefers consistently moist soil compared to desert cacti. Water the plant when the top 2–3 cm (1 inch) of soil feels dry. Reduce watering in the winter dormant period to prevent root rot. Overwatering can cause stem softening and rot, so ensure proper drainage and avoid waterlogging. The plant's slender stems may lose rigidity when thirsty, so monitoring soil moisture is helpful.Humidity
Mistletoe Cactus enjoys higher humidity levels, ideally above 50%. It naturally grows in humid forest environments, so placing it in a bathroom or kitchen with indirect light can be beneficial. To increase humidity, use a pebble tray with water beneath the pot, mist the plant occasionally, or employ a humidifier.Temperature
Maintain temperatures between 18–29°C (65–85°F) for optimal growth. This plant is not frost-tolerant and should be protected from temperatures below 10°C (50°F). Avoid placing it near cold drafts or heating vents that cause rapid temperature fluctuations.Soil & Potting
Use a well-draining, slightly acidic potting mix designed for cacti or epiphytic plants. A mixture of cactus soil with added orchid bark, perlite, or coarse sand improves drainage and aeration. The Mistletoe Cactus prefers a moist but not soggy substrate. A pot with drainage holes is essential to prevent water accumulation.Feeding
Feed monthly during the active growing season (spring through early fall) with a balanced, diluted fertilizer formulated for cacti or houseplants. Avoid fertilizing in winter when the plant is dormant. Over-fertilizing can damage roots and reduce plant vigor.Repotting
Repot every 2–3 years or when the plant becomes rootbound or outgrows its container. Spring is the best time for repotting. Choose a pot slightly larger than the current one, refresh the soil, and gently handle the trailing stems to avoid breakage.Propagation
Propagation is easiest via stem cuttings. Select healthy segments 10–15 cm (4–6 inches) long, allow the cut end to callous for a day or two, then plant in moist, well-draining soil. Keep the cutting in a warm, humid environment with indirect light until roots develop. Seeds can also be used but are less common and slower.Common Problems
Stem Softening and Rot
Caused by overwatering or poor drainage. Fix by reducing watering frequency, improving soil drainage, and removing affected stems.Yellowing or Browning Stems
Often a sign of too much direct sunlight or low humidity. Move the plant to a shadier spot and increase humidity.Pests: Mealybugs and Spider Mites
Look for cottony masses or fine webbing. Treat infestations with insecticidal soap or neem oil and isolate the plant until pests are controlled.Leggy Growth
Occurs from insufficient light. Provide brighter indirect light and prune back long stems to encourage bushier growth.Wilting or Shriveling Stems
Usually due to underwatering. Increase watering frequency and check soil moisture regularly.Toxicity & Pet Safety
The Mistletoe Cactus is considered non-toxic to cats and dogs, making it a pet-safe choice for households. However, as with any plant, ingestion of large amounts may cause mild digestive upset. Its trailing stems are spineless and pose minimal physical risk.Seasonal Care
During the growing season (spring to early fall), maintain regular watering, feeding, and moderate humidity. In winter, reduce watering and halt fertilization to allow dormancy. Avoid cold drafts and keep the plant in stable temperatures above 10°C (50°F). Outdoor placement in partial shade during warm months can promote flowering and stem hardening.Quick Tips
- Provide bright, indirect light but avoid direct sun exposure.
- Keep soil evenly moist but well-drained; reduce watering in winter.
- Maintain humidity above 50% for healthy growth.
- Use a well-draining cactus or epiphyte potting mix with added grit.
- Feed monthly with diluted balanced fertilizer during spring and summer.
- Propagate easily with stem cuttings for sharing or new plants.
- Watch for pests like mealybugs and spider mites, and treat promptly.
