Designed for reliable, efficient irrigation of young trees and shrubs, the Hunter RZWS1825 Root Zone Watering System delivers water and oxygen directly to the root zone to encourage deep, healthy root growth. The pre-assembled, enclosed cylinder and protective grate keep irrigation hardware secure while internal baffles direct flow where roots need it most.

  • Patented StrataRoot™ design: Internal baffles distribute water, oxygen, and nutrients evenly across the root zone for improved establishment.
  • Factory-installed 0.25 GPM bubbler: Provides consistent, low-flow irrigation ideal for trees and shrubs.
  • 18" irrigation cylinder: Delivers moisture throughout the root profile for deeper, healthier roots.
  • Pre-assembled, enclosed design: Quick installation with added protection from vandalism and debris.
  • Durable construction: Rigid cylinder and grate provide long service life in landscape and municipal settings.

Use the RZWS1825 where targeted root-zone irrigation is required—new plantings, street trees, parks, and commercial landscapes benefit from reduced surface runoff and more efficient water use. Documents including an installation card, brochure, product overview, and cutsheet are available with the product to guide correct placement and setup.
