    Structural pruning using ANSI pruning methods


    Pruning the correct live branches can have a dramatic impact on how trees respond to gravity, wind, and ice storms. Structural pruning designed to reduce growth rate and weight on codominant limbs is the most effective method of minimizing damage from storms. We will thoroughly decipher thinning, reduction, raising, and structural pruning. Learn how to:
      • Provide the latest scientifically-based tree care to your customers
      • Contrast structural pruning with other ANSI pruning methods on mature trees
      • Combine pruning methods to meet customer expectations
    First we will learn how branches develop strong connections to the trunk, and what makes them weak. Then we will show details on how trees fail and why and how to prevent it. We will teach you what to look for when evaluating trees for potential failure and how to treat these trees. Pruning will be conducted on young and medium-aged trees live on video and in slides showing some tree’s response to pruning over a 20 year period!  Although many professionals support the ANSI pruning standards that describes pruning types, there are many variations of pruning applied in the landscape. We will thoroughly decipher thinning, reduction, raising and structural pruning. You will go home with a new understanding of how and why we prune trees, and how to apply it to most real life situations. This presentation will help you provide the very latest in tree health care to your customers including research so new it’s not yet published.
