This is the second in our series on pruning deciduous bonsai. Like the previous one (beech), these illustrations are simple and easy to follow, and could apply to most other deciduous trees with alternate leaves. The illustrations are from Bonsai Today issue 41.

The branch where it says strong branches that are too long, could also be faulted for being too straight. Where it says branches that curve unnaturally it could say any unsightly branch (eg branches that have reverse taper or the have abrupt jagged angles). Just bear in mind most conventions and rules are made to be broken.
