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. Suits container cultivation but attention to watering is needed in dry spells during the growing season. See Japanese maple cultivation

Propagation

Propagate by grafting in late winter or softwood cuttings
