Fertilizing Trees and Shrubs


Trees and shrubs need 16 major and minor nutrients for healthy growth throughout the year. In the forest, plants absorb these nutrients from decaying material on the ground.

In urban settings, we remove debris before it has a chance to decay and enrich the soil. Urban trees and shrubs also face hardships from pollution. Regular fertilization counters those conditions, giving your plants a better chance of thriving and creating a healthy, attractive landscape for your home or business.

The fertilizer that Garpiel Group uses is specifically formulated to promote both root development and the overall health of your trees and shrubs.

The most important nutrients provided by fertilizer are nitrogen, phosphorus and potassium. Nitrogen promotes strong color and top growth, phosphorus stimulates root development, and potassium helps with disease resistance and water retention. Root development is vital to helping your trees and shrubs draw water and nutrients from the soil. Disease resistance helps improve the overall health of your landscape.

The fertilizer we use is made from food grade ingredients, so the nutrients are ready to be used by your trees and shrubs as soon they enter the vascular system. Your trees and shrubs do not have to use energy to break down the nutrients. Instead, the nutrients are readily available.

Fertilizing in the fall is critical. Plants use nutrients throughout the year in different ways. Spring fertilization promotes growth. In late fall, established trees or shrubs take the nutrients from the soil and apply them to important health-promoting functions, such as disease resistance and root development. The excess nutrients are stored in the roots and become immediately available when needed for new growth in spring.

Fertilization throughout the year helps newly-planted trees and shrubs grow and establish themselves. It helps mature trees and shrubs maintain overall health and vigor.
