How to Grow Avocado in Tropical Australia

Soil
Extremely well-drained, slightly acidic 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.
Salt
Sensitive. Struggles with salty bore water or salty soil. Give it rainwater if you can.
pH Range
5.5-6.5
Sunlight
Full sun. Protect young trees from harsh afternoon sun with shade cloth for first 2 years.
Good companions
Nasturtium, Comfrey
Keep away from
Anything that needs regular digging around root zone. Avocado roots are shallow and easily damaged

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.

Storing and preserving avocado

How to keep it
  • Freezing (puree). Mash ripe flesh with 1 tbsp lemon juice per avocado. Pack into containers leaving 1cm headspace. Freeze flat in zip-lock bags. Keeps: 4-6 months.
  • Guacamole freezing. Make guacamole, press plastic wrap directly onto surface (no air), freeze in portions. Keeps: 3-4 months.
  • Oil infusion. Avocado oil can be pressed at home with appropriate equipment but commercial pressing is more practical. Keeps: Variable.
