- Gradually reduce watering frequency; allow soil to dry slightly.
- Apply final feed of season to build reserves for winter.
- Perform structural wiring and light pruning before leaf color.

The care sheet
The constants — what stays true in every season.
Full sun to partial shade
Provide afternoon shade in very hot climates.
Moderate
Let topsoil dry slightly between waterings.
Balanced
Use low-nitrogen in late summer to harden growth.
Structural in early spring, maintenance through summer
Leaf prune in midsummer to promote second flush.
Spring or Autumn
Check wire monthly - trunks thicken fast.
Every 2 - 3 years
Repot in early spring before bud break.
Cuttings or seed
Air layering also effective for mature material.
Protect roots from deep freeze in containers.
Ensure consistent moisture during peak heat.
