High-pressure root fertilization is very beneficial to trees suffering from construction damage, decline, over-mulching and improper planting depth.


In common practice, many trees are grown in nurseries in excessively deep soil, and then planted even deeper in landscaping. To make matters worse, trees are routinely over-mulched. This contributes to the formation of girdling roots and root-collar rot, which result in the death of many trees every year.


However, many trees in these conditions can be saved by performing relatively simple root-collar excavation and girdling root removal procedures, in which a Nelson’s arborist uses high-pressure compressed to remove soil from the root zone without causing damage to the tree. This reduces soil compaction and allows the addition of compost and minerals, promoting healthy new root growth.

Trees require nutrients to live and thrive. When one or more essential nutrients are deficient in the soil, a tree cannot reach its full landscape potential. Consequently, it will be more susceptible to disease and insect problems, resulting in a shorter lifespan than a similar well-fertilized tree. The most common symptoms of nutrient deficiency include reduced growth, leaf chlorosis, yellowing and necrosis.

Insects and diseases can also threaten tree health. Environmental stress weakens plants, making them more susceptible. Our team carefully examines your trees, diagnosing problems through specific symptoms of damage in order to understand the causes. Fungicides, insecticides, antibiotics and nutrients are then injected directly into each tree’s vascular system to treat its specific insect, nutrient and disease problems.

This treatment helps trees prepare for or recover from stress related to construction damage, drought, insects and disease. It also helps improve a tree’s overall health by strengthening its root system and creating a denser canopy. This is accomplished by redirecting the tree’s energy away from twig growth and toward other areas, including root and leaf development. This exciting new treatment will help save and improve many trees that may have otherwise been lost.


Growth Reduction

Although species vary, vegetative growth can generally be reduced by approximately 40 to 60% over a three-year period after just one treatment. However, growth reduction within the first year of treatment may not be as noticeable as in subsequent years.


Root System Enhancement


Plant growth regulation can increase the fine root density in species including oaks, elms and lindens. This results from the re-allocation of carbohydrates from the canopy that are not needed for vegetative growth.


Improved Drought Tolerance


Drought is a major cause of tree death and decline, especially in urban landscapes. Research has shown that plant growth regulation increases drought resistance by helping trees reduce water losses during hot, dry periods.


Increased Tolerate to Death and Disease


Plant growth regulation changes some important physical traits of leaves. Some of the more notable changes include increased leaf thickness and hairs as well as thicker leaf cuticles. These changes tend to improve water status of leaves and may present additional physical barriers to pathogen invasion.

Nelson’s has the experience, expertise and ability to work with you and with construction teams to review projects, providing the best solutions to minimize the risk of harm to your trees. Our goal is to help trees survive and thrive for many years after construction is complete.

No tree is completely safe. Trees with defects in their roots, trunk or branches are likely to fall, potentially causing personal injury or property damage. At times, even healthy trees can fall. Our experts will examine and inspect the trees in a systematic fashion, letting you know if your landscape contains high-risk or potentially hazardous trees and recommending the proper course of care and action.
