Construction exposed Tree Roots for 3 years

Question

I read all your articles about not covering naturally exposed tree roots with dirt. My situation is I had to have some grading done about 3 years ago, which exposed a 40 year old Pine tree roots. The thing I am worried about is about 2 months ago (before I read your article), I covered two roots about 4″ in diameter to a depth of 6″ to one foot of dirt to install retaining wall 2 months ago. Should I go back an uncover roots?

Answer 1

The amount of soil that you covered the surface roots with should not cause an issue.
