Tree Diapers

TreeDiaper™ Is an Effective Irrigation System

TreeDiaper™ is a revolutionary new way to care for plants and trees. It is a patented self-maintaining plant hydration system that absorbs over 200 times its weight in water for slow release into the soil below.
It is the first and only product to combine the functions of slow release irrigation, automatic recharging with natural precipitation, and weed control into one low-cost package.

The super slow release rate maintains soil moisture levels, allowing you to stretch out your water supply. The large watering area provides enough moisture for trees and shrubs to survive dry spells—and more importantly, encourages root growth for healthier plants. After all, moist soil absorbs and retains water better; water just runs through over-dry soil. Experience the TreeDiaper™ for yourself.
