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.

Sanctuary Tree PHC Services

We believe in proactive tree and shrub care to preserve the aesthetics of your landscape, maintain the health of your green assets, and enhance your property’s value. Trust us to provide the expertise, quality, and commitment your trees and shrubs deserve.

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.

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.

ArborJet Trunk Injection: The Future of Tree Protection

ArborJet’s 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, our trunk injection techniques, backed by ArborJet’s equipment and formulations, stand out as the gold standard in safeguarding trees against pests.

Efficient and User-Friendly: ArborJet’s drill-plug-inject procedure is straightforward and fast. While suitable for the avid DIY enthusiast, it’s best executed by a professional, particularly for complex challenges.
Eco-Conscious Approach: ArborJet’s direct tree injection minimizes environmental impact, keeping your family, the applicator, and the surrounding environment safe from potential hazards.
Economically Savvy: Modernized equipment and formulation costs offer value. This cost-efficient solution benefits both homeowners and service providers, maximizing benefits without compromising quality.
Championing Urban Greenery: Major urban centers like Chicago and Milwaukee trust ArborJet’s trunk injection method to protect their green assets. With two years of robust protection, over 115,000 boulevard trees in these cities flourish, showcasing the system’s efficacy.

Our Testimonies

I can’t say enough about Ryan and Sanctuary Tree!

I can’t say enough about Ryan and Sanctuary Tree! Ryan came out to look at our trees and shared a ton of information about them and what they need! We have a tree that we love and is struggling, Ryan trimmed it and told us what we need to do to help it. He also trimmed our apple tree in back and explained what it needed to remain healthy. His work is impecable and his knowledge unbelievable! His is the best!

We’ve already recommended to all of our neighbors!

We had Ryan out to check out three trees on our property. He did a thorough job inspecting the trees and an incredible effort in diagnosing an issue we had with one of them. While the other folks I had out for bids came and went quickly, he took his time to look around at options on how we could address a crack in our large hackberry. I really appreciate his attentiveness and the quality of his work. He really cares about the trees we have in our neighborhood. We’ve already recommended to all of our neighbors!
