Japanese red maple

Also known as: hananoki

A deciduous tree to around 20m tall forming a rounded crown when mature. Shallowly-lobed leaves emerge bronze-green in the spring and turn shades of orange, yellow, red and purple in the autumn; the undersides of the leaves have a whitish bloom. Small clusters of red flowers are borne on the bare branches in spring and followed by reddish winged fruits in the summer

Fertilizing

Slow release tree feed in spring

Pruning

Little pruning is needed. Remove diseased, damaged, crowded or crossing shoots and unwanted growth. Timing depends on the plant: generally late winter or early spring; plants prone to bleeding and deciduous magnolias need different timing, and deciduous azaleas and lilacs are pruned after flowering.

Propagation

Propagate by seed or by grafting

Growing

Grow in a moist but well-drained soil. Acid soils will give the best autumn colour
