BioAdvanced 12-Month Tree & Shrub Protect & Feed is an easy-to-use systemic solution that combines powerful insect control with slow-release fertilizer in a single, annual application. Its dual-action formula is absorbed by the roots and moves up through the entire plant to provide protection from the inside out, making it rainproof and effective for a full year.
 
Staggs Garden Center likely recommends it because it offers gardeners a "set it and forget it" approach to protecting their most valuable, long-lived plantings from devastating threats like the Emerald Ash Borer, Japanese Beetles, Adelgids, Aphids, and Scale, while the integrated 2-1-1 NPK slow-release feeding promotes long-term health and vigor.
