Oh, also, if you're not in an agricultural type of situation, like where your neighbors have to see the trees, then the surround kind of dusts around the area being exposed. A lot of my trees have mulch around their ground area, and the surround dusted the mulch in an unsightly way as well. If you're farming a hillside or acre somewhere that no one gets to see, it's totally fine. I think the product is very innovative and works well (and as advertised), it's just messy. It also holds to the tree even after light to medium (and successive) rain.
