Bare Trees Prime for Pruning

Leaves are now on the ground, but trees still need attention. Mid-winter is actually a good time to prune most non-flowering trees.

Trees are dormant in the winter, making pruning easier because you can better see a tree's structure when no leaves are on the branches. Without leaves it is easier to spot dead or broken branches that need to be removed in order to help avoid breakage resulting from harsh winter weather.

Deciding what and where to prune involves an understanding of basic tree biology, sharp tools, and an artful eye. The International Society of Arboriculture (ISA) emphasizes a few simple principles to understand before you prune:

• Prune with a purpose-Remove dead or diseased wood, provide clearance, or improve structure
• Use proper technique-Improper cuts can cause long-term damage.
• Make small cuts- Creates less damage to the tree than large cuts.
• Make cuts just outside the branch collar- Allows for faster wound closer.
• Do not leave stubs.
• Only use sharp and clean tools.

  "Proper pruning is an important part of tree health maintenance," according to Jim Skiera, Executive Director of the ISA. "Every tree is different. Pruning at the wrong time, pruning incorrectly, or pruning too much may create more problems than not pruning at all," says Skiera. When in doubt it is best to hire a professional arborist to do the pruning for you.

  If pruning a tree cannot be done without using power equipment or leaving the ground, then it should be done by an ISA Certified Arborist. Pruning of large trees can be dangerous and should be performed by a professional.
