Evergreen subtropical tree that has become Australia's most fashionable fruit. Three races: Mexican (cold-hardy, small fruit), Guatemalan (medium hardiness), and West Indian (tropical only). Most commercial varieties are Guatemalan or Guatemalan-Mexican hybrids. Hass dominates but is not the only option. Trees can become VERY large (15m+) if not managed. Grafted trees fruit in 3-5 years; seedlings are a genetic lottery and take 7-15 years.

How to Grow Avocado in Tropical Australia

When to Plant

Plant at start of wet season (October-November) for establishment. Avoid planting in heavy wet season rains.

Soil
Extremely well-drained, slightly acidite to neutral. Avocados CANNOT tolerate waterlogged roots. Phytophthora root rot is the #1 killer. Sandy loam ideal. Heavy clay is death. If you have clay, build a raised mound 50-60cm high.
pH Range
5.5-6.5
Sunlight
Full sun. Protect young trees from harsh afternoon sun with shade cloth for first 2 years.

Companion plants: Comfrey, Sweet potato ground cover, Nasturtium

Avoid planting near: Anything that needs regular digging around root zone. Avocado roots are shallow and easily damaged

Tropical Growing Tips for Avocado

Recommended Varieties

  • Shepard (B-type, excellent tropical performer)
  • Wurtz/Littlecado (A-type, compact)
  • Reed (A-type, large round fruit)
  • Choquette

Key Challenges

  • Extreme humidity drives Phytophthora and anthracnose
  • Cyclone damage to mature trees
  • Poor fruit set in very high temperatures

Pro Tips

  • Drainage is absolutely critical, raised mounds essential.
  • Shepard is the best tropical commercial variety for good reason.
  • Mulch heavily but keep mulch 30cm from trunk.

Harvesting Avocado

When ready: Avocados do NOT ripen on the tree. Harvest when fruit reaches full size and skin begins to lose glossy sheen (Hass turns slightly purple-black). Pick one and leave at room temperature. If it ripens evenly in 7-10 days without rubbery texture, the crop is ready.

How to harvest: Cut stem with secateurs leaving 1cm stub. Never pull fruit. Handle gently. Bruises show as brown flesh.
