Fertilizing Trees and Shrubs

In urban or suburban neighborhoods, trees and shrubs often need fertilizing. Modern home- building methods create adverse growing conditions for plants. Often, good topsoil is completely removed and not replaced. Heavy machinery scrapes and compacts fertile soil, reducing its aeration and drainage. Plants are crowded by streets and sidewalks, and must compete with grass for nutrients. Proper fertilization is especially important to landscape plants in this type of environment.
