A newly scissor-pruned bonsai, a Trident Maple/Acer buergerianum by Harry
Harrington
The effect of pruning this way is to overcome the effects of apical growth,
strengthening the inner and lower growth whilst holding back the upper and
outer branches. This technique results in a more even spread of energy

throughout the tree.
One effect of pruning harder in the apical areas than the weak, lower areas of
the tree is that the bonsai retains a triangular silhouette.
As each new shoot is pruned, 2 or more new, smaller shoots emerge in its
place. Repeating the process of maintenance pruning throughout the year
produces increasing numbers of smaller shoots, which produce a dense 'pad' of
foliage.
A developing tree that requires increased trunk or branch thickness can be
allowed to extend uninhibited for a period before being pruned back. This will
allow the branch to thicken and to a limited extent, the trunk, from the point
where the branch emanates, downwards. If left completely unpruned however,
the tree will become coarse and lose its shape.
