Certified and Licensed
Did you Know?
80% of landscape problems are due to soil issues
The name Colorado comes from the Spanish word “color rojo,” meaning “the color red”, which refers to the red dominant soils in our landscape. The red is a result of the high iron content within the soil. And yet, Colorado’s highly calcareous soils tie up the iron in a form unavailable to trees, shrubs and plants.
High soil pH can also negatively affect plant growth. pH can be described as the measure of acidity or alkalinity of soil and is measured on a scale of 1 to 14 where 7, which is neutral, is the optimal level for most plants. Numbers lower than 7 are considered acidic and numbers higher than 7 are considered alkaline or calcareous (high in calcium carbonate). Colorado soils that have never had amendments added may have a pH value of up to 8.5, which is higher than most plants can tolerate — especially acid-loving trees such as maples.

EMERALD ASH BORER (EAB) TREAMENTS
Emerald Ash Borer (EAB), a non-native insect, was found in Boulder, CO in 2013. Since then it has spread to Longmont, Lyons, Broomfield, Lafayette and Arvada. EAB attacks all types of Ash trees (except mountain ash). Trunk injection provides 24 month protection against EAB.
TREE AND SHRUB NUTRIENT / FERTILIZER APPLICATIONS
Nutrient/Fertilizer applications help trees obtain nutrients that are difficult for most species of trees to get from our Rocky Mountain soils. Balanced nutrition can prolong the life of a tree, help resist pests and disease and help tolerate drought.

Why we charge for assessments and diagnosis of tree disease.
My name is Ryan and I am an experienced disease specialist with an honest approach to tree care and I do not sell unnecessary services that are so often seen with ‘Free Estimates’. My approach to a healthy tree is to educate you, as the steward of that tree, in all the things you can do to promote good tree health. There are times when I will recommend services, but ultimately it is through education that I help you understand your landscape needs and the best management practices to improve the health of your living landscape.

Trunk Injection: The Future of Tree Protection
The innovative trunk injection method revolutionizes tree insect and pest control. By injecting directly into the trunk, the formulation is rapidly absorbed and spread throughout the tree, ensuring optimal protection. With over a decade of rigorous research and development, the techniques used, backed by superior equipment and formulations, stand out as the gold standard in safeguarding trees against pests.
