Exposed Tree Roots
Many of trees have exposed tree roots that are pretty beat up by the lawnmower. Ive read that this means the soil is too shallow and also read that you cant put soil (or mulch) on top of them, because the roots will suffocate and the tree will die. This seems like an extreme opinion, because tree roots go deep. So the exposed tree roots arent their only means of getting nutrition.
What comments to you guys have?
