Large deciduous nut tree native to the Mississippi River valley in the USA. Gets very large (15-30m) and needs ample space. Produces thin-shelled nuts with rich, buttery kernels. Needs warm summers, cold winters, and LOTS of water. Cross-pollination between varieties is essential for nut set. Long-lived (100+ years) but slow to reach full production (8-12 years). Pecans do surprisingly well in Australia's irrigated inland zones.
How to Grow Pecan in Subtropical Australia
When to Plant
Plant bare root June-July.
- Soil
- Deep, fertile, well-drained alluvial soil. Originally a bottomland/riverbank tree - likes rich deep soil with good moisture-holding capacity. Tolerates some clay better than most nut trees. Deep taproot needs minimum 2m soil depth.
- pH Range
- 6.0-7.0
- Sunlight
- Full sun. Needs high heat units for nut maturity.
Companion plants: Grass (orchards often grassed), Legume cover crops
Avoid planting near: Buildings, infrastructure (massive tree)
Subtropical Growing Tips for Pecan
Recommended Varieties
- Wichita (Type I, scab resistant)
- Western Schley (Type II)
- Shawnee (scab resistant)
- Pawnee (Type I, early)
Key Challenges
- Scab in humid conditions
- Need scab-resistant varieties
- Cross-pollination essential
Pro Tips
- Plant ONLY scab-resistant varieties in SEQ humidity.
- Wichita + Western Schley is a classic Type I/Type II combination.
- Trees get enormous - allow 12m spacing minimum.
Harvesting Pecan
When ready: Shuck (outer green covering) splits and separates from shell. Nuts fall from tree. Shell colour darkens.
How to harvest: Collect fallen nuts from ground (shake branches to accelerate). Remove shuck remnants. Dry in single layer in shade for 2-3 weeks.
