We moved into a house in town a couple years ago. And the more I read about
trees the more I realize the beautiful mature oak tree and maple tree in my front
yard are stressed and unhappy. They are 3 feet from the road and sidewalk evenly and the soil keeps eroding from there
roots because the street curb is lower then the sidewalk by about 2.5 feet. Any idea how to save these trees and keep the soil from eroding on the steep grade? Or are they doomed and plan to have them removed later on? We are in zone 5 if that helps at all. Thank you!
