Landscape trees and shrubs have unique soil needs - different from turf and other plantings. Without healthy soil, trees and shrubs cannot grow as they should. Nutrition, compaction of the soil and the availability of water all effect plant growth.
As tree roots grow and develop in autumn, now is an ideal time to evaluate the need for fertilization. Because every soil is different, sometimes even on a single property, the best way to determine what your trees need is through soil analysis.
During soil analysis, a soil sample is taken from beneath the tree and analyzed to determine its composition and health. With this information in hand, a fertilization program can be customized to the exact nutritional needs of the tree. Customizing the fertilizer based on soil analysis yields the best results for root development in autumn, and helps trees and shrubs prepare for a healthy growing season next spring.
