Growing Bonsai Trees: The Importance of Balance in Pruning

The Role of Apical Branches in Bonsai Tree Growth

Auxin and Cytokinins: In the world of bonsai tree cultivation, the removal of apical branches serves a crucial purpose in shaping the tree's growth and promoting a compact form. The essential developing point at the highest point of the stem of a plant is known as the terminal bud. This is where new growth, such as leaves or flowers, emerges on the plant.

Function of Terminal Buds: Terminal buds produce auxin, a plant hormone that promotes apical dominance, which is critical for vertical growth and inhibits the growth of lateral branches. On the other hand, cytokinins are responsible for promoting lateral bud growth and branching.

Disruption of Balance

When apical branches are removed in bonsai tree pruning, it disrupts the balance between auxin and cytokinins within the plant body. By removing terminal buds, which are key sites of auxin production, the plant loses its source of auxin, leading to a decrease in apical dominance and an increase in lateral branching.

This disruption in balance can impact the overall growth and form of the bonsai tree, potentially altering its aesthetic appeal and health. Therefore, it is essential for bonsai growers to carefully consider the implications of pruning practices on the hormonal balance of their trees.
