More than 25 people contemplated trees and discussed how to effectively and safely prune them during the field session of the recent Pruning Workshop. After a morning indoor presentation, Vince Urbina, Colorado State Forester, gave everyone the opportunity to use by-pass pruners or a pruning saw on the trees near the Alamosa Ranch Ramada picnic area east of Cattails Golf course.
For the workshop, Urbina worked from the ground on small- to medium-sized trees. He emphasized knowing why you're pruning and to never remove more than 25% of the tree canopy in a year.
Once a tree is established (usually 2-3 years after planting), it's time to begin routine pruning maintenance. Structural pruning for most shade trees involves establishing a dominant leader.
Deciding which of the leaders should remain as the dominate leader. Structure pruning
may take more than one year.

It’s also important to realize that branches less than 8 ft. from the ground are considered temporary branches and are usually removed as the tree matures and has established branches higher up.
The Alamosa Tree Board and Colorado State Forest Service sponsored the workshop. Audrey Liu and Jan Oen, Alamosa Tree Board members, provided the wonderful lunch that included donated Kretsinger (KW Farms) beef and salad greens from the Alamosa Community Greenhouse. The Green Spot donated coffee.
