Troubleshooting
Grinning Argyroderma problems — and how to fix them
Grinning Argyroderma (Argyroderma ringens) 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.
Rot in the fissure
Water pooling in the wide gap between the lobes causes bacterial and fungal rot at the crown. Always water at the soil level or use bottom-watering. If rot is detected, remove affected tissue, dust with sulphur fungicide and keep dry.
Failure to split into new leaves
If the plant does not produce a new leaf pair after autumn watering resumes, it may be in too deep a dormancy or roots may have died. Check roots, ensure autumn temperatures drop slightly (to 15–20°C nights), and begin watering to trigger the growth cycle.
Etiolation and loss of form
Insufficient direct sun causes the lobes to grow tall and lose their flattened, grinning form. Move to maximum available light; existing distortion is permanent but new growth will correct in better conditions.
