Troubleshooting
Scarlet Banana problems — and how to fix them
Scarlet Banana (Musa coccinea) 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.
Spider mites
Common in low-humidity indoor environments. Treat with insecticidal soap spray and improve ambient humidity to prevent reinfestation.
Scale insects
Brown or white scales on pseudostems and leaf midribs. Scrape off manually and apply horticultural oil to eliminate remaining crawlers.
Root rot
Overwatering or poorly draining containers cause corm rot. Always use free-draining compost and ensure pots have adequate drainage holes.
Bract color fading
Insufficient light causes the characteristic scarlet color to fade to orange or dull red. Move to the brightest available position.
