How to Grow

Cultivation

Grow in any moisture-retentive, well-drained soil in a sheltered position. Leaf colour is best in partial shade, although full sun can be tolerated if soil is reliably moist. Leaf scorch can be caused by lack of soil moisture or excessive exposure. See Japanese maples cultivation

Propagation

Propagate by softwood cuttings, layering or by grafting. Plants grown from seed are unlikely to come true, but may still be garden worthy

Suggested planting locations and garden types

City and courtyard gardens
Cottage and informal garden
Patio and container plants

Pruning

Pruning group 1, only from late autumn to mid-winter

Pests

May be susceptible to aphids and scale insects, including horse chestnut scale

Diseases

May be susceptible to Verticillium wilt, Acer leaf scorch and honey fungus
