Instead of watering bags that consume water, the Tree Diaper recharges itself with natural precipitation. The super slow-release irrigation, which runs from weeks to months rather than a few hours for watering bags, encourages root growth of newly planted trees and shrubs and enables plants to thrive over time. In addition to using 97% less water, the device helps prevent soil erosion, serves as a weed control barrier, and reduces the public grounds maintenance costs. Zynnovation. BOOTH #240
