Troubleshooting
Triangular Rhipsalis problems — and how to fix them
Triangular Rhipsalis (Rhipsalis trigona) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Black, mushy stems
Overwatering or a dense mix retaining too much water. Repot into a free-draining epiphytic blend and water only after the surface dries.
Wrinkled, deflated segments
Underwatering or low humidity. Increase watering frequency and ambient moisture; Rhipsalis is not drought-loving like desert cacti.
Reddish, sun-stressed stems
Too much direct light. Move to bright indirect light and the stems regain their green tone with new growth.
No flowering
Typically too little light or no winter rest. Brighten its position and give a cooler, drier winter to prompt spring flowers.
