Tree Management

Propagated by seed or from natural seedlings that regenerate under mature trees. Propagation by cutting, grafting, and air layering also possible. Germination and seedling vigor improve with seed size. Only large seeds should be used in nurseries. Early seedling growth is very slow. Under intensive care, it takes 10-18 months to get a pencil-thick stem suited for grafting or planting, but plants may require up to 36 months to develop in most nurseries. Seedlings should be place in pots and planted when 1 m tall.
