Tree Fertilization

Denver Tree Fertilizing

Denver tree fertilizing can be tricky, thanks to our arid climate. While in normal years tree fertilizing helps, in especially dry years you risk burning out the leaves.

Consistent tree fertilization allows your trees to better provide their own natural defense against insects and disease. There are also added benefits such as; more blossoming, stronger branching. Better fall color. And more vigorous growth.

Here are the different techniques that our Denver tree fertilizing service uses and why we do. We recommend these approaches for Denver area trees.

Soil Drench/Deep Root Fertilization

We recommend spring and fall fertilization using a soil injection. The chemical is put into the soil and then moves from the roots to the leaves through the tree blood system (cambium layer). Soil injection may last up to 225 days, depending on the health of your trees and shrubs.

Micro Injections

A micro injection fertilization procedure injects chemicals directly into the tree by drilling holes through the bark. This means less chemical use and no run-off. Micro injection usually lasts 30 to 75 days. Because small holes are drilled into the tree, this should not be done year after year because repeated drilling can damage the tree.

Root Stimulator Applications AKA Fall Fertilization

Fall fertilization is a misnomer because no fertilizing compounds are actually used. Instead, it’s more of a root building treatment to encourage tree root development specifically the fine root hair development. A fall application should limit nitrogen as excessive nitrogen can upset the tree’s natural cycle into winter dormancy. The main difference between root stimulator applications and deep root fertilization is that a root stimulator uses little to no iron and nitrogen.
