Cathedral Bells problems — and how to fix them
Cathedral Bells (Kalanchoe pinnata) 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.
Root rot
Waterlogging causes quick stem collapse. Let soil dry adequately and use free-draining compost.
Mealybugs
White powdery insects in leaf axils and stem joints. Treat promptly with isopropyl alcohol or insecticidal soap.
Invasive plantlets
Like other viviparous Kalanchoe, dropped plantlets root freely. Remove them from other pots to prevent unwanted spreading.
Fungal leaf spots
Humid conditions or water on leaves can lead to brown spots. Improve air circulation and avoid overhead watering.
Failure to flower
Requires short days (about 8 hours of light) for 6 weeks to initiate flowering. Cover with a dark cloth or place in a darker room at night to trigger blooms.
