The exposure to bright light improves the autumn colour. Anyway shade the tree in high summer, to avoid burnings to the leaves. In winter, shelter it from very cold temperature (-10 C and over).

Everyday, in the vegetative season. Do not water the leaves in sunlight, to avoid burning due to glass effect. In winter water it less frequently, but do not let the soil get dry.

Start fertilizing as soon as the buds open. Once a week, during the first month, then every two weeks up to late summer, setting aside the summer months.

In alternate years, for the first 10 years, then according to the needs: when the roots completely fill the pot. Use universal mould.

In spring, shorten the new growth to 2-3 leaf buds. Remove the biggest leaves during the whole vegetative season. Keep the internodes closer, removing drastically the longest ones. The complete trimming by mid-summer gives smaller leaves and a brighter autumn colour. The best moment to wire is just after the trimming.

By seeds in winter. By semi-wood cuttings in summer. By layers in spring or summer.
