Hashiri-eda

Hashiri-eda is a Japanese term that means "a running branch". It refers to a branch that grows much stronger than other branches, especially in deciduous trees. A hashiri-eda may come out when a tree goes off balance and extends its thick root into the soil. In bonsai, a hashiri-eda can be used to create a new tree by air layering or cutting it off and planting it separately. However, a hashiri-eda can also disrupt the balance and harmony of the bonsai design, so it may need to be pruned or wired to control its growth.
