Troubleshooting
Black Cardamom problems — and how to fix them
Black Cardamom (Amomum subulatum) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Rhizome rot from waterlogging
Despite needing consistently moist soil, Amomum subulatum is susceptible to root and rhizome rot if the root zone becomes truly waterlogged. Ensure pots have generous drainage holes and never stand them in water-filled saucers.
Leaf scorch and dehydration
Large leaves lose moisture rapidly in dry or draughty conditions; tips and edges brown and curl quickly if humidity drops below 60% or the plant dries out even briefly. Maintain high humidity and never let the compost fully dry.
