Hikobae is a Japanese term that refers to the emergence of an indefinite bud (futeiga) from under the surface at the root of a tree. It also means the bud itself. This phenomenon often occurs in shrubby, multi-trunk species of plants. Hikobae buds can weaken the tree if left unremoved, but they can also be used for propagation by division in some cases. Hikobae is related to bonsai because it is a technique to create new bonsai material from existing trees.
