Trees & shrubs in the woods benefit from rich soil created by decomposed leaves and from the “insulation” provided by other trees against storms in the woods. Trees & shrubs in a suburban or urban setting do not enjoy these benefits and may suffer from competition for nutrients and water from lawns, encroaching driveways, roads, sidewalks, injury from construction, etc.
Fertilization can help to address nutrient deficiency, discourage disease and insect problems and help your trees and shrubs to be healthy and beautiful.
