Crown thinning is the removal of a small portion
of secondary and small live branches to produce a uniform density
of foliage around an evenly spaced branch structure. Crown thinning
includes crown cleaning and should not alter the overall size or
shape of the tree.
Why have it done?
It is usually confined to broad-leaved, hardwood species and is
used to increase the light penetration and air movement throughout
the crown of the tree or to lessen the weight of heavy branches.
This can improve the tree's structure and form.
