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.
Leaf and Bark Beetle Treatments
Leaf and Bark Beetles are one of the top tree pests in Colorado. Treatments vary depending on type of tree and pest associated. Elm leaf beetles are an example of leaf damaging beetles.
Winter Watering
Winter watering of trees is essential for keeping trees healthy during our typical winter dry spells from November through March.
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.

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.
