As their names indicate, tree protectors and tree shelters are designed to protect and shelter trees. They are supposed to protect trees from deer browse and rub, rodents, wind, drought, winter crack, sun scald, mowers, weed eaters and herbicides.
Unfortunately, some shelters cause other problems in the course of solving these. And some of these problems can result in substantial tree loss. There are just too many variables that affect tree health and growth to rely on guesswork.
Designing a protector that has just the right mix of qualities to optimize tree health while minimizing potentially damaging side-effects is a difficult balancing act. Not everyone can do it and, in fact, only TREE PRO has been able to achieve that balance.
