Rhipsalis sulcata - Mistletoe Cactus

Rhipsalis sulcata, commonly referred to as the Mistletoe Cactus, is a slender, pendulous species within the cactus family, native to the Atlantic Forest of southeastern Brazil. It typically inhabits shaded woodland areas where it grows on tree branches or occasionally on rocky surfaces, benefiting from the filtered light of the forest canopy.

The stems are narrow, elongated, and often distinctly ribbed with fine grooves running lengthwise. They can extend for considerable lengths, forming cascading curtains of growth. The branching pattern is irregular, with segments producing new growth from their tips. The surface is smooth, and the stems are green to slightly yellowish-green depending on light exposure.

Small, white to pale cream flowers emerge along the stem margins, usually in spring to early summer, followed by translucent to whitish berries that contain seeds. These fruits are dispersed by birds and other wildlife, aiding the species' spread through its native range.

Care Tips:

• Light: Prefers bright, indirect light; avoid prolonged direct sun which can scorch stems.
• Water: Keep evenly moist during active growth, allowing the top layer of media to dry slightly between waterings; reduce in winter.
• Humidity: Benefits from moderate to high humidity; mist occasionally in dry indoor conditions.
• Media: Use a free-draining mix with organic matter, such as fine orchid bark blended with peat or coir.
• Temperature: Thrives between 15–27°C; protect from frost.
• Fertiliser: Apply a diluted, balanced fertiliser every 4–6 weeks during the growing season.
• Repotting: Repot every 2–3 years or when the plant becomes pot-bound, preferably in spring.
