People who have to “manage” everything don’t stop to realize that trees have been healing scars and broken limb damage from wind storms, lightning strikes, ice and snow and heavy fruit loads for eons. Long before the pruning paint was concocted, trees healed themselves from frost cracking, sun burning, and scars from being hit by adjacent windthrown trees.
Dr. Shigo, who did autopsies on many dead trees, discovered that trees with even the most irregular and shattered breakages compartmentalize wounds, shut off the area to liquid flow, and begin healing growth in one year’s time.
When I first did arborcultural work, we didn’t have pruning paint. Instead, house paint was supposed to seal the branches and exclude fungus spores. Even latex paint soon cracked and peeled. Then creosote-based asphalt paint stuck, stretched and stayed …
