Care Guide
Placement
Full sun
Sunlight essential to reduce internode length.
Watering
Moderate
Let soil surface dry slightly between watering.
Fertilization
Balanced
Light feeding in early spring and midsummer.
Pruning
Structural in early spring, maintenance after flowering
Responsive to hard pruning; control apical growth.
Wiring
Spring or Autumn
Wire early; bark scars easily and heals slowly.
Repotting
Every 2-3 years
Repot in spring; use well-drained soil with some grit.
Propagation
Cuttings or seed
Can be grown from acorns or air layered.
Winter: Very cold hardy; protect container roots in deep freeze.
Summer: Tolerant once established; reduce water in extreme heat.
Zone 8b: Protect roots if temps < 20 F
Seasonal Calendar
Late Dormancy02-15 — 03-10
- watering

- repotting
- Prepare for repotting if needed; finalize substrate and pot choices.
- pruning
- Minor structural pruning can be done now if needed to reduce large branches before repotting.
- wiring
- Avoid wiring during cold spells. Only if structure requires correction before bud swell.
- pests disease
- Inspect for overwintering pests like scale or spider mites; clean bark if needed.
- winter protection
- Shelter from late frosts. Protect roots from freeze-thaw cycles using mulch or a cold frame.
- wound management
- Seal large pruning wounds to prevent desiccation.
- deadwood carving
