Commercial Tree Fertilization

Keep the trees and shrubs on your commercial property healthy and beautiful.

Tree and shrub fertilization is the key to beautiful, healthy commercial Colorado landscapes.

The needs of young trees are different from the needs of mature trees. A three-stage fertilization process protects young and new trees from the time they’re planted throughout their maturity.

Swingle, based in Denver since 1947, employs more certified arborists than any other Colorado company. We offer the most comprehensive Tree Fertilization services available.

Swingle’s three-stage tree fertilization treatment system is specifically formulated for trees in Colorado’s climate:

First Four: Stage One Treatment is designed to increase root development in newly planted trees and shrubs. Swingle recommends these treatments once a year for the first four years after planting.
Root Builder: Stage Two Treatment is formulated for established trees and shrubs and provides the nutrients to alleviate nutrient-deficient soils, which are common in Colorado. Swingle recommends these treatments once a year until the tree reaches its mature stage.
Root Builder Mature: Stage Three Treatment encourages root growth in mature trees and shrubs. Swingle recommends this treatment once a year throughout the life of the mature tree.

All Swingle services include free Courtesy Visits from your Landscape Care Consultant and are backed by our 100 percent guarantee.

Help your new tree grow into a source of family pride, a provider of shade with professional fertilization.
