Troubleshooting
Tiny Dunce Cap problems — and how to fix them
Tiny Dunce Cap (Orostachys minuta) 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.
Mealybugs
The tiny, tightly packed rosettes are prime mealybug habitat. Check regularly at leaf axils and treat promptly with isopropyl alcohol swabs and neem oil.
Root rot in winter
If kept damp during dormancy, roots quickly rot. Move to a cool, dry position from late autumn; do not water until fresh growth emerges in spring.
Post-bloom die-back alarm
Blooming rosettes are monocarpic and die after flowering. This is normal — stolon-rooted offsets surrounding the spent rosette will fill the space. Remove dead material promptly to prevent fungal spread.
