Thinning of the crown
can increase light penetration through the tree it also reduces
weight in branches and the sail effect of the crown (how much
wind it stops).
Care must be taken not to over thin as this can lead to
a decrease in leaf area thus having an adverse effect on photosynthesis.
Thinning should be carried out evenly through the crown and
not just by removing the inner crown foliage this creates
the effect known as “lion Tailing” where all the
growth is situated at the end of branches resulting in an
unsightly trees and higher chances of branch failure.
