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.

How to Grow Banana in Subtropical Australia

When to Plant

Plant September-February when soil is warm. Growth slows dramatically May-August.

Soil
Deep, rich, well-drained loam with high organic matter. Bananas are gross feeders and need fertile soil. Sandy soils need heavy composting.
pH Range
5.5-6.5
Sunlight
Full sun, sheltered from strong wind. Wind shreds leaves (cosmetic damage) and can topple plants.

Companion plants: Sweet potato (ground cover), Comfrey, Lemongrass

Avoid planting near: Nothing specific, but keep away from structures due to spreading root mat

Subtropical Growing Tips for Banana

Recommended Varieties

  • Lady Finger
  • Ducasse
  • Goldfinger
  • Cavendish (Williams)
  • Blue Java (Ice Cream Banana)

Key Challenges

  • Winter cold slows growth to near-zero (below 14°C)
  • Frost kills leaves, severe frost kills pseudostem
  • Longer time to fruit than tropical (15-24 months from sucker)

Pro Tips

  • SEQ grows excellent bananas. Lady Finger is the best performer for backyard growers.
  • Protect from frost in first winter. Hessian wrap or frost cloth on pseudostem.
  • North-facing position against a dark-coloured wall or fence is ideal.

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).
