Skyline Locust vs New driveway...
I have a Locust tree approximately 40ft tall, 20 years old within 8' of a driveway. In recent years about 4 roots have pushed up bumps in the driveway. What are the chances of seriously damaging the tree if these roots are removed during a driveway replacement? Are locusts particularly tolerant or susceptible to root disturbance? Please advise. Thanks, Mark
