Carpinus betulus
European Hornbeam
Deciduous broadleaf with fine twigs and excellent leaf reduction; strong apical dominance.
Care Guide
Placement
Full sun to partial shade
Protect from intense sun in summer to avoid leaf scorch.
Watering
Moderate
Keep evenly moist; sensitive to dry spells.
Fertilization
Balanced
Feed biweekly during growing season for best growth.
Pruning
Structural in spring, maintenance summer
Hard prune just before bud break; responds well.
Wiring
Spring or Autumn
Wire young shoots; mature wood hardens quickly.
Repotting
Every 2-3 years
Repot in early spring; reduce roots moderately.
Propagation
Cuttings or seed
Air layer old branches; cuttings root slowly.
Winter: Hardy; mulching pot base helps in freezing climates.
Summer: Provide mulch or moss to reduce surface heat.
Zone 8b: Watch for spider mites (Jul-Aug); Prevent rot in wet Nov-Jan
