Troubleshooting
Dwarf Cavendish Banana problems — and how to fix them
Dwarf Cavendish Banana (Musa acuminata 'Dwarf Cavendish') 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, tearing leaf edges
Mostly cosmetic from wind and low humidity; leaves naturally split. Persistent crisping points to dry air or underwatering.
Spider mites
Thrive in dry indoor heat, causing fine stippling and webbing on leaf undersides. Raise humidity and rinse foliage; treat with insecticidal soap.
No fruit / stalled growth
Almost always too little light or cold. Bananas need sustained warmth (above 18°C) and bright direct sun to flower and fruit.
Corm or root rot
Yellowing collapse from waterlogged, cold soil. Use a free-draining mix, a pot with drainage holes, and cut back winter watering.
