As a part of our grant program, we used the GreenWells to help establish young, 1-5 gallon trees. The Greenwells helped protect the young trees from weeds and grass, allowing water to penetrate the roots. The GreenWells have also prevented things like lawnmowers, weedwhackers, and pets from harming the trees. GreenWells provide a controlled environment that keeps water and mulch in. We like what we are seeing so far!
