Fertilizers for Ornamental Trees and Shrubs

Trees and shrubs don’t always need fertilizer, especially if they’re mature and healthy. If you fertilize your lawn often, there may be enough fertilizer in the soil for the trees and shrubs to use. However, when used when necessary at the right amounts and at the right time of year, your trees and shrubs can benefit greatly from the nutrition fertilizer provides.

Before fertilizing, determine if it is necessary. If your trees and shrubs are displaying signs of poor health and growth, eliminate other factors like disease and pest damage, before adding fertilizer to fix the problem. Always read fertilizer labels closely and follow all directions and application rates for successful results.
