EVOLVE Tree and Shrub granular fertilizer is perfect for all your existing or new trees, shrubs, annuals and perennials. The pellets break down slowly so your plant can efficiently use all of the organic ingredients. EVOLVE's CLAY BUSTER technology creates pores in your soil system which helps roots penetrate deeper into the clay underlay. This means your trees and shrubs will stay healthy even during over and under watering situations. EVOLVE Tree and Shrub can be used at any time of the year including freeze up (when many others cannot)
