How to select and install a Root Watering System
The Rain Bird Root Watering System (RWS) consists of a perforated polyethylene cylinder with 14,000 openings to effectively deliver water, air and nutrients to the root system of trees and shrubs. It easily connects to irrigation lateral lines or can be installed in drip zones. It is available in 3 sizes: 36", 18" and 10".
Benefits include:
· Optimal growth rates ­ Deeper root growth and root mass means a healthier, faster growing tree
· Investment protection ­ Healthier roots help trees survive transplanting and provide stability in high winds
· Watering efficiency ­ Subsurface irrigation minimizes run-off and evaporation · Landscape aesthetics ­ Installs at grade and helps minimize damage to hardscapes
Easy to install in just 3 simple steps:
1 Choose correct RWS units 2 Determine number of units per tree/shrub 3 Space appropriately
SEE PAGE 2 FOR DETAILED INSTRUCTIONS
Dig hole and insert tree/shrub before installing RWS to avoid damage to units.

Keep RWS top even with ground surface.
Keep RWS on its own irrigation zone.
