Why fight your tree's growth with constant pruning? Tree Growth Regulators (TGRs) redirect energy from unruly branches into root development and natural defense, preserving your view and your tree’s health.
Trees in urban Eugene often grow too fast for their own good, leading to structural instability and constant maintenance. If you’re facing these challenges, a Growth Regulator is the proactive solution:
At Eugene Tree Health Care, we use advanced TGR technology to "slow down the clock" and improve the biological resilience of your landscape.
We reduce vegetative growth by approximately 40% to 60% over a three-year period. This significantly reduces the frequency of pruning and keeps your tree at its "ideal" size for longer.
By slowing down branch extension, the tree redirects its energy (carbohydrates) underground. This results in a denser, more fibrous root system that is better equipped to find water during dry Oregon summers.
TGRs increase the thickness of the leaf cuticle and stimulate the production of abscisic acid. This helps your trees close their stomata more efficiently, reducing water loss during Willamette Valley heatwaves.
One of the most striking "side effects" of our applications is a deeper, darker green in the foliage. Because the tree is growing more compactly, the chlorophyll becomes more concentrated, making the tree look vibrant and healthy.
Our application is clean, non-invasive, and designed for long-term results.
The Deliverable: Each client receives a Canopy Management Plan, which includes a multi-year pruning cost-savings analysis and a technical summary of the treatment applied.
Controlling the biology of a living giant requires more than just a shovel; it requires the precision of a licensed professional.
In the lush environment of Eugene, trees grow faster than in many other parts of the country. We understand the growth rates of our local Bigleaf Maples, Willows, and Redwoods intimately. Eugene Tree Health Care calibrates our applications to the specific soil types of Lane County, ensuring your tree gets exactly what it needs to stay healthy, compact, and beautiful without the stress of constant "hacking."
The actual application is quite fast, usually taking 30 to 60 minutes. The soil around the base of the tree is slightly disturbed for the injection, but we rake it back so it looks untouched when we leave.
No. Growth Regulators slow down the "stretching" of the branches (internode elongation), but the tree continues to produce new leaves and maintain its health. It just stays in its "pruned" shape for much longer.
Visible changes in leaf color can often be seen within the first growing season. The reduction in branch growth is usually most apparent the year after application, once the regulator has fully integrated.
Yes. We apply the regulator directly into the soil at the base of the trunk where the tree's feeder roots are most active. This targeted approach prevents impact on surrounding turf or ornamental garden beds.
For most species in the Eugene area, a single application provides consistent results for three full years. We’ll notify you when it’s time for a "booster" to maintain the tree’s compact form.
TGRs are a type of plant hormone regulator. While they are a professional-grade product, they are widely used in urban forestry specifically because they allow us to save trees in tight spaces that would otherwise have to be removed.
