How to Grow Mistletoe Cactus
Rhipsalis spp.
Mistletoe cactus is a trailing, epiphytic jungle cactus from South American rainforests — very different from desert cacti. It thrives in bright indirect light with moderate humidity, and needs watering when the top 2–3 cm of soil dries out. Feed monthly in spring and summer, reduce in autumn, and stop in winter to encourage its delicate white winter flowers and translucent berry-like fruit. Non-toxic to cats and dogs, making it ideal for pet households.
Yearly Lifecycle
Care Essentials
Feed monthly with a half-strength balanced liquid fertiliser from spring through summer. Reduce to every 6–8 weeks in autumn and stop entirely in winter.
Watch For
- Mealybug
- Root rot from overwatering
- Scale insects
- Shrivelled stems from low humidity or drought
Pet Safety
Care Requirements
Light
Bright indirect light; no direct sun
Place near a north- or east-facing window, or set back from a bright south-facing window. Direct summer sun scorches the stems.
Watering
Water when top 2–3 cm dries out
Jungle cacti need more water than desert cacti but must not sit in soggy soil. Water thoroughly, allow to drain, then wait for the top 2–3 cm to dry before watering again. Reduce frequency in autumn and winter.
Fertilizing
Monthly at half strength in spring and summer
Apply a half-strength balanced liquid fertiliser monthly during the growing season. Skip feeding in autumn and winter to allow a rest period.
Pruning
Minimal — remove dead or damaged stems
Rhipsalis rarely need pruning. Remove any dead, damaged, or shrivelled stem segments at the joint. You can trim back excessively long stems to keep the plant tidy.
Spacing
Pot in a 20–30 cm hanging basket
Use a well-draining cactus or epiphyte mix. Repot every 2–3 years or when roots fill the pot. Slightly root-bound plants often flower better.
Support
None required — naturally trailing
Rhipsalis are naturally trailing and cascading. A hanging basket or elevated shelf displays the stems best. No staking or support needed.
Growing Tips
Not a desert cactus
Rhipsalis are jungle cacti from tropical rainforests. They need humidity, indirect light, and regular watering — not drought conditions or full sun.
Hang it up
Trailing stems look best in a hanging basket. Keep it away from heating vents and cold draughts, which cause shrivelling.
Reduce water in winter
Cut back watering significantly in autumn and winter. This brief dry rest period triggers the small white or cream flowers that appear in late winter.
Safe for pets
Non-toxic to cats and dogs, making it one of the few cacti safe to display at floor level in pet households.
