Oak Tree Root Damage
Help! I was clearing out from under some large 30'+ oaks today trying to get rid of those invasive shrubs that want to take over the woods. I am afraid that I may have cut and removed some oak tree roots by mistake. It is impossible for me to tell. The roots were very close to the trunk of the tree in some cases wrapping around the trunk. I am unsure if I damages the root system and I am just sick that I may have injured the tree! The roots in question were about the size in diameter of my pinky finger and two to three feet long. I can't tell if they belonged to the tree or to the shrubs that I wanted to destroy.
Can anyone give me information about this. What I understand is that root pruning should be done with a very clean cut and then sealed. Well, I just yanked them out in pieces. Is there anything I can do at this point to help the tree just in case?
