Troubleshooting
Cacao problems — and how to fix them
Cacao (Theobroma cacao) 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.
Low-humidity leaf browning
Dry indoor air is the commonest problem, browning leaf edges and dropping leaves; sustained high humidity is essential to keep it healthy.
Cold sensitivity
Chilling below about 10°C damages foliage and stops growth; keep it consistently warm and away from cold draughts and windows.
Leaf scorch in direct sun
As an understorey tree, full sun bleaches and burns the leaves; provide bright filtered light or light shade.
Mealybugs, scale and thrips
Warm, still indoor conditions invite sap-sucking pests on the soft foliage; inspect regularly and treat with horticultural soap or oil.
Prevent cacao problems before they start
Most cacao issues are care-mismatch, not bad luck. Dial in the basics:
