The Legacy-Tree system is a containerization and planting method that works with a tree's physiology instead of against it. Many trees in our urban forests have significant and often fatal issues created by the issue of deep planting. These trees live shortened lives, unable to put proper growth into structure and energy into immunities. The Legacy-Tree system addresses these issues by creating an environment that focuses on outstanding root health and development at the proper depth. No Legacy-Tree is planted without expert consultation to ensure proper species selection to site conditions and to encourage consideration of our biodiverse range of trees. Legacy-Tree is the culmination of the life's work of Ronald Zillmer, an industry leading expert of tree development and physiology.
