Troubleshooting
Rhinephyllum broomii problems — and how to fix them
Rhinephyllum broomii (Rhinephyllum broomii) 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 and crown rot
The plant is extremely sensitive to excess moisture, especially when cool. Use a very gritty mix, water only when bone dry, and keep nearly dry during dormancy to prevent rot.
Loss of leaf texture and etiolation
In weak light the warty grey leaves smooth out, stretch, and lose colour. Provide full sun to keep the characteristic rough, compact rosettes.
Fungal leaf spotting
Humid, still air and overhead watering can cause spotting on the rough leaf surfaces. Improve ventilation and water at the base rather than over the foliage.
Mealybugs
Mealybugs shelter in the textured leaf crevices and crown. Inspect closely and treat with isopropyl alcohol or a systemic succulent insecticide.
