Technically the world's largest herb, not a tree. The 'trunk' is a pseudostem made of tightly wrapped leaf bases. Propagated by suckers (pups) from the base of the mother plant. Commercial bananas are seedless and sterile. Each pseudostem fruits once then dies, replaced by suckers. Strictly tropical/subtropical in Australia. Biosecurity restrictions apply to plant movement between states due to Panama disease.

Cold / Highland Growing Tips for Banana

Key Challenges

  • Frost and cold kill plants outright

Pro Tips

  • Do not attempt. Bananas need consistent warmth and cannot survive highland winters.

Harvesting Banana

When ready: Fingers (individual bananas) are plump and rounded (not angular/ridged). Flower petals at tip of each finger dry and rub off easily. Wait until fingers start to turn slightly yellow on the bunch, OR harvest when full-sized but green and ripen indoors.

How to harvest: Cut entire bunch with machete or heavy knife. Support bunch weight as you cut. They're heavier than you think (15-40kg). Hang in cool shady spot to ripen. Ripen faster in paper bag with ethylene-producing fruit (apple).
