It's prized as an ornamental specimen for its striking year-round visual appeal and manageable size.

Growing Conditions

☀️
Sun: Partial shade preferred; morning sun with afternoon shade in hot climates (zones 7-8). Tolerates full sun in cooler zones (5-6) but may develop leaf scorch in intense afternoon heat.
💧
Water: Consistent moisture is critical; water deeply 1-2 times weekly during growing season, more frequently in hot weather. Keep soil evenly moist but not waterlogged. Reduce watering in fall and winter. Drought stress causes leaf scorch and leaf drop.
📏
Spacing: 60-120 inches (5-10 feet) depending on mature size desired and neighboring plantings inches
📅
Days to maturity: Not applicable for ornamental trees; reaches mature ornamental size in 10-15 years
🌱
Planting depth: Plant at same depth as root ball; top of root ball should be level with ground surface

Soil

Type: Well-draining, slightly acidic loamy soil with organic matter
pH: 5.5-6.5
Amendments:
Compost or aged bark mulch Peat moss or coconut coir for moisture retention Perlite or coarse sand for drainage Avoid lime; acidifying sulfur if soil is too alkaline

Growth Stages

1

Establishment (Year 1-2)

12-24 months

Young tree focuses on root development; foliage emerges red to burgundy in spring, gradually darkening through early summer

Water consistently; apply 2-3 inches of mulch; avoid fertilizing first year; prune only to remove damaged branches; stake if in windy location

2

Vegetative Growth (Year 2-5)

3-4 years

Tree develops stronger branching structure; color deepens to dark burgundy; new growth continues to emerge red before darkening

Maintain consistent moisture; begin light formative pruning in late winter; apply balanced fertilizer in spring if growth is slow; watch for pests

3

Mature Foliage (Year 5+)

Ongoing

Tree reaches ornamental size; displays deep burgundy summer color; branching becomes more dense and architectural

Prune for shape in late winter; maintain soil moisture during dry spells; fertilize annually in early spring; monitor for disease

4

Fall Color Transition (Autumn)

4-6 weeks

Foliage transforms to brilliant orange-red and crimson tones; color intensifies before leaf drop

Ensure adequate moisture as leaves begin to change; avoid heavy pruning; enjoy the spectacular display

5

Dormancy (Winter)

3-4 months

Deciduous tree loses all leaves; elegant branching structure becomes prominent; buds form for spring growth

No watering needed except in drought; prune for structure in late winter (January-February) before buds break; avoid climbing or heavy snow accumulation

Common Pests

  • Handpick beetles in early morning; use Japanese beetle traps away from tree; apply spinosad or neem oil if infestation is severe

  • Prune out heavily infested branches; apply horticultural oil in dormant season; spray insecticidal soap during active growth if severe

  • Increase humidity with regular misting; spray neem oil or insecticidal soap; ensure adequate watering to reduce stress

  • Prune out infected branches; improve air circulation; rake and destroy fallen leaves; apply fungicide in spring if disease was severe previous year

  • No cure; improve soil drainage and avoid wounding trees; remove severely affected branches; mulch to regulate soil temperature
