The major sacrifice branch came off a couple of years ago, and the tree has been decandled at least one or two times before. Japanese black pine – 13 years from seed Lower trunk (tachiagari) and surface root […]

A common approach to developing bonsai from scratch is to focus on trunk development first and branch refinement second. When we focus on developing the trunk, we generally encourage rapid growth until the trunk reaches the desired size. Much slower growth is useful when focusing on branch ramification. Between these two stages of development is […]
