How to Grow Katsura Tree
Cercidiphyllum japonicum
Katsura tree is a graceful, well-behaved tree grown as much for its fragrance as its looks. In autumn, the falling leaves release a warm caramel or candyfloss scent that fills the garden on still days. Heart-shaped leaves emerge flushed pink-purple in spring, turn fresh green for summer, then butter-yellow to apricot in autumn. Plant in moist, well-drained soil in a sheltered spot with sun or dappled shade. It dislikes drought and wind — keep the root zone mulched and water through dry spells, especially when young. Minimal pruning needed.
Yearly Lifecycle
Care Essentials
Rarely needs feeding in average garden soil. Apply a balanced slow-release fertiliser in spring only if growth is noticeably poor.
Watch For
- Generally trouble-free
- Leaf scorch in drought or wind
- Honey fungus on stressed trees
Companions
Hostas, Ferns, Astilbe, Ligularia
Care Requirements
Light
Full sun to dappled shade
Best colour in full sun. Tolerates partial shade well. Avoid deep shade which reduces autumn colour intensity.
Watering
Regular watering; dislikes drought
Water regularly throughout the growing season, especially in the first three years. Katsura is more drought-sensitive than most ornamental trees — mulch and water during dry spells.
Pruning
Minimal; late winter only
Remove dead or damaged branches in late winter. The natural form is elegant and should be preserved with minimal intervention.
Mulching
Annual spring mulch essential
Apply a 5–7 cm layer of well-rotted compost or leaf mould each spring to retain moisture. Keep away from the trunk.
Growing Tips
The caramel scent
The fallen leaves in autumn release a distinctive warm caramel or candyfloss fragrance on still, damp days. Plant near a path or seating area to enjoy this fully.
Moisture is essential
Katsura dislikes drought. Mulch the root zone every spring and water during dry spells, especially in the first three years. Leaves may scorch and drop early if too dry.
Shelter from wind
Cold drying winds cause leaf scorch. Choose a sheltered spot or plant with the protection of larger surrounding trees or a wall.
