Old growth and protected-trees are worth history and culturally in Korea. This research carried out to investigate habitat characterization and the vegetative propagation methods of Salix chaenomeloides(100-600 years old trees) in Gyeongsangnamdo Province. It has been preserved in good and grow naturally in area surrounding village(4 trees), riverside(1 tree) and field(1 tree). Cutting from old growth and protected trees was conducted using 10 kinds of bedsoils. It was survived above 93% in all bedsoils. Growth of cuttings is a distinct difference according to bedsoils and tree ages. Growth of cutting was high on CBS, followed mixed bedsoils (VPMP) including vermiculite, peatmoss and perlite. Root collar diameter was difference depend on tree ages and bedsoils. All trees are produced 1 to 4 branch. Root growth of cutting was 20 cm on CBS and VPMP, which is the best shoot growing on cutting. Bedsoil with physico-chemical characteristics of high moisturizing ability, high air permeability, high EC value and slightly acid may be suitable for efficiently cutting propagation of old growth and protected S. chaenomeloides. CBS and VPMP bedsoil are favorable for propagating this species by cuttings.
