Front Range Recommended Tree List

Think of young trees as living sculptures. Trees need a little help developing proper (ideal) structures as they age in an urban setting. Consider these four objectives when thinking about corrective tree pruning. Removing dead or damaged branches, maintaining a single leader(trunk), Select the lowest permanent branch, thin and maintain other temporary branches below the lowest permanent branch until eventual removal.
Something to consider when pruning young trees in Berthoud, is when selecting the lowest permanent branch, consider its orientation. If the branch will be growing over a town-owned sidewalk or road, make sure the branch is at least 8 feet above a sidewalk or 14 feet above a road.
 
For a more expanded fact sheet on pruning young trees, follow this link to the Colorado Master Gardener program for their Structural Training of Young Shade Trees. 

If you have any questions about how to prune your young tree, you can email the town forestry staff at forestry@berthoud.org. We are happy to answer any questions!
