Denver Tree Fertilizing

Tree fertilizing in Denver can be tricky thanks to our arid climate. Consistent tree fertilization allows your trees to better provide their own natural defense against insects and disease. You can achieve the same results in your landscape with the added benefits of:

• More blossoming.
• Stronger branching.
• Better fall color.
• More vigorous growth.

Here are the types of tree fertilization we recommend for the Denver area.

Basal Bark Application

A basal bark application is the quickest way we know green up your trees. EnviroTree, a patented natural plant food specifically made for the Rocky Mountain West and the arid conditions we get in Denver, is applied by spraying it directly on the bark from 3 feet high downward to the soil level.

Because the tree fertilization process is water soluble, it can be absorbed through the bark.  EnviroTree is remarkable in reversing premature yellowing of the leaves due to chlorosis and the accompanying winter die-back.

We recommend a 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 Injection

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.
