Tree Growth Regulator

Extend clearances to support your reliability and resiliency efforts.

Wire Zone Resilience

Tree Growth Regulator (TGR) application is a powerful, underutilized tool within an Integrated Vegetation Management (IVM) strategy—especially for maintaining wire zone clearance while reducing reliance on repeated mechanical trimming. By redirecting a tree’s energy from upward limb elongation to increased root density, fuller canopy development, and improved water retention, TGR helps stabilize growth and limit regrowth that can threaten conductors. The result is extended clearance cycles, improved tree health, and a more predictable, cost-effective maintenance program aligned with utility performance goals.

What if Trees Grew Half as Fast?

As a wire zone clearance solution, TGR is highly effective for cycle-busters, yard trees, and recently trimmed spans where regrowth pressure is highest. It works both as a preventative measure and as a way to extend already achieved clearances—diminishing the impact of resurgent growth and significantly reducing the need for mid-cycle trimming. This approach not only lowers long-term vegetation management costs but also minimizes customer disruption and enhances the overall reliability of the system.
