Troubleshooting
Snow Banana problems — and how to fix them
Snow Banana (Ensete glaucum) 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 damage
Large leaves shred easily in strong winds. Position in a sheltered spot or secure plants in exposed gardens.
Root rot
Overwatering or poorly drained soil leads to pseudostem and root rot. Ensure the pot or bed has excellent drainage.
Spider mites
Dry indoor conditions encourage spider mite infestations on the undersides of leaves. Increase humidity and spray with insecticidal soap if needed.
Frost damage
Even brief frosts blacken and kill the foliage. Bring containerised plants indoors before first frost or heavily mulch the base outdoors in marginal climates.
Nutrient deficiency
Yellowing or pale new leaves often indicate magnesium or iron deficiency. A foliar spray of diluted seaweed extract or a magnesium sulphate drench resolves this quickly.
