FREE online courses on Vegetable Gardening - Pruning - Pruning Mature Trees
Before you start pruning, look at the tree from a few angles
and decide what you'd like to accomplish.
That could be to change the shape, raise the crown, open up
the center or any number of things.
Whatever goals you set, you should remove any dead or
crossing branches. They hinder a tree's growth.
You should also eliminate branches growing at narrow angles
to the main vertical branches. They form narrow angle crotches that are much
weaker than joints formed by branches growing at wide angles.
TIP:
When cutting off a branch, always leave the branch collar intact, the thickened area where it joins the trunk.
But if stub is long enough to hang a hat on, then you haven't cut enough.
Try to work slowly, thinking about your cuts and their impact
before actually doing them. A second opinion is often valuable, so you might
work with a partner.
