How much of above ground root can i trim off of my ginkgo tree?

Question

Our 30 year old ginkgo tree has some roots protruding above ground. Can we cut these off so our lawn mower won’t?

Answer 1

It is not recommended. Cutting or shaving tree roots can affect the stability of the tree plus leave it open to insect and disease invasion.
