Our lives are full of environmental stressors. We all know what they are:
- large workloads
- processed food
These stressors can cause disease. Trees, like humans, are susceptible to environmental stressors as well.
Just a few examples of tree stressors are:
- low moisture
- competition from other trees and shrubs
- nearby construction
Thus, it is important to provide your trees the best food and nutrients so that they can fight disease and insect issues, while enabling a long and healthy life.
Fall tree fertilization promotes root growth. Healthy roots contribute to:
- more blossoms
- stronger branching
- better fall color
- vigorous growth
Fertilizing in the fall will ensure that the proper nutrients are available to the tree during its typical growth spurt in the spring.
Below are the types of fertilization that ArborScape can recommend for trees in Denver.
Basal Bark Application
A basal bark application is the quickest way we know to green up your trees. Using EnviroTree, a patented natural plant food, we apply it by spraying it directly on the bark from 3 feet high downward to the soil level.
Because it 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.
ArborScape recommends 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.
The chemical is directly injected 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.
