In order for young plants and trees to thrive, it's critical they receive a healthy, steady irrigation flow and the exchange of air from day one. Developed to meet this challenge, the Root Zone Watering System features Hunter’s patented StrataRoot design, which is a series of internal baffles that deliver water where it’s needed most. The RZWS is pre-assembled to save time, and the enclosed design and grate protect irrigation hardware from vandalism. For efficient irrigation of trees and shrubs delivered at the root, the Hunter RZWS is the solution.
