Troubleshooting
Camille Dumb Cane problems — and how to fix them
Camille Dumb Cane (Dieffenbachia 'Camille') 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.
Cream centres turning green
Insufficient light causes the low-chlorophyll central areas to produce more chlorophyll and revert towards green. Move to a brighter (but still indirect) position to restore the pale cream variegation.
Stem rot at the base
Overwatering is the most common cause of rotting canes at soil level. Remove the plant from the pot, cut away all rotted tissue, dust with fungicidal powder, and repot in fresh, drier mix. Allow the wound to callous before watering.
Spider mites in dry conditions
Check the undersides of leaves for fine webbing and stippling. Increase humidity, wipe leaves with a damp cloth, and apply insecticidal soap or dilute neem oil solution every 7 days until the infestation clears.
