01Drainage is everything
Avocados are extremely sensitive to waterlogged soil — root rot is the number one killer. Plant slightly proud of grade on a mound if drainage is at all uncertain.
02Planting
Method
Plant with the root flare at or slightly above soil level, on a mound if drainage is marginal.
Soil
Free-draining above all else; moderately fertile.
Timing
Plant in spring in warm, frost-free zones.
03Growing care
- Never let the tree sit in wet soil — err on the dry side over wet.
- Mulch well beyond the drip line, kept clear of the trunk.
- Stake and shelter young trees from wind — brittle branches snap easily.
- Feed lightly with a citrus/avocado-specific fertiliser through the growing season.
04Problems
- Root rot (Phytophthora) — the major risk; ensure sharp drainage above all else.
- Wind damage — brittle wood; shelter and stake young trees.
- Fruit drop — normal to a degree; heavy drop points to water stress or poor pollination.
- Sunburn on bark — young trunks; wrap or paint with white tree paint.
05Harvest & storage
Signs
Fruit doesn't ripen on the tree — pick at mature size then ripen off the tree over several days.
Method
Cut with a short stem attached, don't pull.
Curing
Ripen at room temperature, faster next to a banana.
Storage
Ripe fruit in the fridge a few days once soft.
