Company Info: Why did you get into tree care? We got into tree care with a belief that not every tree in the urban forest should be cut down: some could be saved. It is this belief that drives us towards better research and innovation. Our mission is partly to improve the science and predictability of tree healthcare, but being a tree care company ourselves, we know that's only half the game. Running a successful and profitable business is the other part. Trees can't be saved if you can't afford to eat, so we provide selling, marketing, and sales consultation as well. We've been there, we know how it can be. We share the same roots, and we are here to help you.

Trimtect Growth Regulator

Trimtect is the newest generation of growth regulators formulated specifically for ground covers, perennials, vines, shrubs, and small trees. It is applied as a foliar spray or a soil drench at the base of the plant. Trimtect is absorbed into the xylem through the actively growing tissue. Whether through the leaves, stems, or roots, paclobutrazol is translocated to the tip of the plant where it reduces the production of the growth hormone gibberellin. The hormone responsible for regulating cell elongation and expansion.

Cambistat Growth Regulator

Cambistat is a plant growth regulator that slows the vegetative growth of plants by inhibiting gibberellin biosynthesis. Cambistat is designed to gently and predictably slow the growth of trees. A single application provides a long lasting reduction of vegetative growth, effectively extending the trimming cycle of trees and reducing the amount of woody growth that must be removed. In addition, use of Cambistat may cause other plant growth effects that are beneficial for trees such as increased root density, improved drought and heat resistance, and higher tolerance to insects and diseases. Cambistat will also benefit trees that are too large for their growing site and increase the longevity of trees growing in stressful environments.

Q-Connect Tree Injection System

We spoke with scores of tree healthcare applicators, researchers, and business owners around the country about what was good and bad about their current tree injection systems. We heard concerns about durability, ergonomics, and the use of plastic or rubber plugs in the injection site. We set out to create a suite of tree injection devices that kept all the features users enjoyed and fix all the issues that they did not. The Q-Connect was designed to be the go-to system you could use everyday.
