Troubleshooting
Dwarf Cardamom problems — and how to fix them
Dwarf Cardamom (Alpinia nutans) 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.
Brown leaf tips
A common symptom of low humidity, draughts, fluoride in tap water, or irregular moisture. Use rainwater or filtered water and maintain high humidity.
Spider mites
Can colonise foliage in warm, dry conditions. Mist regularly and treat promptly with insecticidal soap or neem oil.
Scale insects
May appear on canes and leaf undersides. Wipe off with a damp cloth and treat with horticultural oil.
Root rot
Occurs in waterlogged conditions. Ensure free-draining soil and avoid leaving pots sitting in standing water.
Failure to flower indoors
Typically blooms on the previous year's canes; cutting all canes back prevents flowering. Allow some older canes to remain.
