How to grow
Plant pups (not seeds) in rich, well-drained soil — bananas are heavy feeders that eat like teenagers. Each 'tree' fruits once and dies, but it sends up pups to replace itself, so a banana patch is really a relay race. In Florida, Dwarf Cavendish and Raja Puri handle the climate; protect from hard freezes with mulch and wraps.
Water & feeding
Lots — bananas are thirsty plants with huge leaves that transpire like crazy. Consistent moisture plus heavy mulch keeps them happy; drought stalls growth and shrinks the bunch.
Common problems
- Panama disease (a soil fungus — plant resistant varieties and never move soil between patches)
- Banana weevils boring into the corm
- Wind shredding the big leaves (cosmetic, mostly)
- Cold damage — foliage dies back in freezes but the corm often resprouts
Harvest
Cut the whole bunch when the fruit is plump but still green; it ripens off the plant. Leave one or two pups to replace the mother stalk, and chop the spent trunk for mulch — it's basically a water-filled compost log.
Nerdy fact: Banana plants are herbs, not trees — the 'trunk' is a pseudostem made of tightly wrapped leaf bases. And the commercial banana is sterile and seedless, propagated entirely by clones, which is why a single disease can threaten the entire global crop.
