How to Grow Japanese Angelica Tree
Aralia elata
Japanese angelica tree thrives in sun or part shade in moist, fertile soil. Its enormous compound leaves and thorny stems create a bold tropical effect. Spreads by root suckers — install a root barrier or remove suckers regularly. White flower panicles appear in late summer. Hardy to zone 4, tolerates urban pollution.
Yearly Lifecycle
Care Essentials
Young trees benefit from a balanced feed in early spring for the first 2-3 years. Established trees rarely need feeding as they are vigorous growers with extensive root systems.
Watch For
- Root suckers spreading beyond desired area
- Spider mites in dry conditions
- Aphids on new growth

☀️ Light
Full sun to partial shade
Produces best foliage in light shade with some direct sun. Tolerates deep shade but growth is less vigorous.
💧 Watering
Regular watering for first 2-3 years
Water regularly during establishment. Drought tolerant once the root system is well developed.
🌱 Fertilizing
Young trees only, early spring
A balanced feed in early spring benefits young trees for their first 2-3 years. Established trees rarely need feeding.
✂️ Pruning
Late winter, minimal shaping
Remove dead wood and unwanted suckers in late winter while dormant. Wear thick gloves — stems are thorny.
❄️ Overwintering
Hardy to zone 4, no protection needed
Fully hardy in most temperate climates. Loses its leaves in winter — this is normal. No wrapping or mulching required for established trees.
Growing Tips
Manage suckers early
Root suckers can appear 2-3m from the parent. Remove them as soon as they appear by cutting below soil level, or install a root barrier at planting time.
Wear protection when pruning
Stems and leaf stalks are armed with sharp thorns. Always wear thick leather gloves and long sleeves when working near this tree.
Site for shelter
The enormous leaves can be damaged by strong winds. Plant in a sheltered spot or against a wall for best foliage display.
