The tree thrives in sunny, warm and humid environments and in well-drained and richly-humic soils. Cold hardy, tolerant to drought, but not to waterlogging. Apply long-active fertilizers once a season from spring to autumn. Mainly propagated by grafting which generally uses green maple as the rootstock.
