ample, I see many weeping cherries that are pruned
into a ball shape because all of the upright limbs were
removed as they grew out of the top. If allowed to
continue growing, these limbs would have eventually
bent back down, creating the weeping effect that gives
the tree its unique look. So it pays to do a little homework
and fi nd out what the tree’s natural shape is and
help it reach its full potential. Not all ornamental trees
need to be pruned into the traditional lollipop shape!
Flowering shrubs should be pruned immediately after
they are done blooming. Non-fl owering shrubs and
evergreens can be pruned as necessary to achieve a
desired shape. Keep in mind that wider at the bottom
is better than narrow — if you allow more sun to
reach the bottom of the shrub, the plant won’t thin out
as much. Avoid heavy, late summer pruning; too much
pruning at this time will encourage new growth that
may not harden off in time for winter. For those plants
that don’t tolerate shearing well, like red or green twig
dogwoods, it is best to prune them back to the ground
when they become too large or sparse, and let them
start over again by growing new limbs from the base.
