Troubleshooting
Japanese Banana problems — and how to fix them
Japanese Banana (Musa basjoo) 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.
Wind shredding of leaves
Leaves naturally split along stress lines in wind — cosmetically undesirable but not harmful. Shelter the plant from prevailing winds to maintain appearance.
Frost dieback
Pseudostems die at 0°C. Cut back to just above ground level, apply a 30-50 cm mulch over the corm, and it will resprout the following spring in zones 7 and above.
Slow spring emergence
In cooler zones, new growth may not appear until late spring. This is normal — the corm is alive and growing from stored energy reserves.
Aphids on young shoots
Emerging spring shoots are targeted by aphid colonies. Remove with a strong water jet or treat with insecticidal soap.
