Accredited Organic Land Care Professional

Christopher Dorion is an Accredited Organic Land Care Professional.

All evaluations begin with a comprehensive soil test. “You can’t manage what you don’t measure”. Your lawn and landscaping should be healthy and safe for pets and humans. The soil test data provides a comprehensive analysis of soil parameters and a pathway forward for optimal soil health. “Feed the soil, not the plant”.

Sample soil test results

The goal is to establish and maintain soil health, which in turn allows for healthy plants.
By eliminating synthetic pesticides, herbicides, and synthetic fertilizers, beneficial organisms flourish and improve both soil and plant health.
Topsoil (black layer) high in organic matter, which supports diverse microfaunal soil communities, high soil moisture retention capacity, and natural, balanced, slow release plant available nutrients.
Is this approach achieving the objective of a healthy, safe lawn?
Trees and shrubs planted in challenging urban settings require proper maintenance and careful monitoring of soil fertility, soil moisture, and human-induced damages. We see here “volcano mulch”, sterile soil, and likely roadway de-icing chemical damage. These types of problems can be overcome with proper plant and soil management.
