of apical growth, also the way that pruning should be carried out to counter it.

Bonsai cannot simply be pruned to the same degree on each and every branch. In
the first diagram of an unpruned tree, it is possible to see that the predominant
growth is around the apically-dominant areas, around the crown and outer
branches. To not only re-shape to a mature form but to also counter the apical
dominance, the tree is pruned harder nearer the top and sides than it is lower
down the trunk. As can be seen in the second diagram, this results in pruning the
tree into a roughly triangular shape.
Pruning this way means that the otherwise weaker inner and lower growth, is
left with more foliage and more vigour than the now weakened apical areas. This
results in a far better distribution of energy throughout the tree as well as
improved form. The effects of this pruning will not last that long though; within
a relatively short period of time the upper and outer areas will recover their
dominance and this again will need countering.
