How to care for Mistletoe Cactus

Rhipsalis baccifera · Cactaceae

cactuseasy to growpet-safe

A spineless, thread-stemmed cactus that dangles from rainforest trees across the tropics — the only cactus species found growing wild outside the Americas. Its soft green strands and tiny white mistletoe-like berries make it look more like a fern than a cactus. Treat it like a tropical houseplant, not a desert dweller. Water roughly every 10 days while it's growing (about every 21 in winter), give it bright, indirect light, kept above 50°F (10°C) — average room humidity suits it.

Care at a glance

Water: every ~10d growing · ~21d dormant
Light: Bright, indirect light
Humidity: average room humidity
Keep above: 50°F (10°C)
Feed: every ~30d in season
Repot: every ~2 years

Keep the airy mix lightly moist in the growing season, watering when the top few centimeters dry — never let it stay bone dry for weeks.

Bright, filtered light or gentle morning sun; hot direct sun reddens and burns the thin stems.

Balanced liquid feed at quarter to half strength monthly in spring and summer.

Mistakes that kill this plant

  • Treating it like a desert cactus and watering once a month.
  • Hanging it in a hot, sunny window where the fine stems fry.
  • Heavy potting soil that suffocates its air-loving roots.

Seasonal tips

  • Raise humidity in winter when heating dries the air — it is a rainforest plant.
  • Slightly cooler, drier late-winter conditions encourage the tiny flowers and berries.
  • Stem segments root easily in spring for effortless propagation.
