Troubleshooting
Wilmot's Dinteranthus problems — and how to fix them
Wilmot's Dinteranthus (Dinteranthus wilmotianus) 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.
Death during spring leaf transition
The plant is at its most vulnerable when producing a new leaf pair in spring. Any watering at this stage channels moisture into the old leaves, which instead of drying down and fuelling the new growth begin to rot. Keep completely dry until the old leaf pair is fully spent and papery.
Root rot in rich or damp compost
Even a slightly too-organic growing medium holds more moisture than Dinteranthus can tolerate. If the plant sits in any hint of damp soil for more than a few days, root rot begins. Repot annually into fresh, very mineral mix and always use terracotta pots to maximise evaporation.
Etiolation in low light
Dinteranthus wilmotianus needs more light than most houseplants. In dim conditions the rounded bodies elongate unnaturally, weakening the plant and making it rot-prone. Supplement a south-facing window with a grow light positioned 10–15 cm above the plant for 10–12 hours daily in winter.
