ARBOR-PLUS™ provides a balanced blend of primary and micro-nutrients with ACT®. These promote quicker healing, deep root growth, plus stronger vertical and horizontal growth of trees and shrubs.

In the soil, ARBOR-PLUS™ Shrub and Tree Liquid Fertilizer promotes aerobic biological activity, helping the soil to breathe which helps to reduce the growth of disease-causing anaerobic bacteria that can destroy roots.
