The Rain Bird Rootzone Watering System (RWS) enables vital water, oxygen, and nutrients reach the tree and shrub root systems by bypassing compacted soil.
The Rain Bird Rootzone Watering System is a great method to irrigate trees and shrubs, especially in places where a system above-ground could be damaged. The Rootzone Watering System (RWS) ensures water is provided quickly down through the soil profile, to the tree’s roots where it is needed. It achieves this by using a Bubbler emitter inside a perforated plastic canister; this allows the water to percolate out of the tube to irrigate within the soil profile. No water is visible from the soil surface, no water is lost in windy conditions and no water is thrown over the foliage or footpaths. It also allows the soil to be aerated as the water travels into the soil profile.
The RWS promotes tree and shrub investment protection, watering efficiency and landscape aesthetics through deep root growth and tree development.
