At Tree Research we are always interested in new innovations, especially where there is an environmental benefit. TreeDiaper (the name is a give away it is an American company!) is a plant hydration system which provides slow release irrigation, keeping young trees hydrated without the maintenance required of a standard tree bag. The collar-shaped tree mats that are placed at the base of young trees and provide water for weeks as opposed to hours. When the rain comes again, the TreeDiaper can store this liquid and start all over again. Great for projects where access to water is an issue and great for urban projects where maintenance needs to be minimal.
