Step One:
--Before you make any cuts, it is important to develop a game plan or goal
for your pruning. This can be as simple as knowing how you want the shrub to
look when you are finished and some basic ideas as to how you might achieve that
outcome.
--Walk around the shrub, assess how it looks, and think about its natural growth
habit.
--What appears to be wrong (or right)? Is it too leggy? Too dense? Lopsided?
Full of dead wood? Is it basically okay but needs some shaping?
Step Two:
--Start by pruning out all dead, diseased, or damaged branches or twigs. If
tissues are diseased, make cuts at least several inches below visible symptoms
and be certain to disinfest tools.
Step Three:
--Remove all crossing, rubbing, or misdirected branches and obvious water
sprouts.
Step Four:
--Before doing anymore pruning, walk around the shrub and note any differences
in its appearance from your first assessment. Is additional pruning necessary to
meet your goal or mental picture of the final outcome? Have you achieved your
goal? Has your goal changed now that you’ve done some pruning? What else might
need to be done?
--Approximately how much of the shrub have you already removed? (Remember: the
rule of thumb for routine or maintenance pruning is to remove no more than 1/3
of the branches at one time.)
Step Five:
--Most pruning mistakes are made by doing this step first!
--Final shaping of the shrub usually requires a combination of heading and
thinning cuts. The approximate ratio of these cuts is determined by the
condition of the shrub and the desired outcome. For example, if the shrub is too
dense, most of the cuts would be thinning cuts; if the shrub is too thin, most
of the cuts would be heading cuts.
--All final cuts should be made to enhance the natural form of the shrub.
--Your pruning efforts should produce a shrub that looks clean and is an asset
to the landscape. A properly pruned shrub should not look "hacked" or
"pruned."
Summary
Pruning is probably one of the least understood and most daunting landscape maintenance practices for most homeowners. Many people aren’t sure how to approach or begin this task. This fact sheet will walk you through five steps for pruning a shrub. It is a companion to the fact sheet entitled "Pruning: An Introduction to Why, How, and When."
