We have a customer who requested a soil test because they cannot get any grass to grow in their back yard. Yard is full of trees, (Not a tree person, don't ask me what kind) and the root systems are majorly exposed and branching all throughout the yard. Yard almost never gets sun.(because of the trees) I'm reluctant to take their money for the soil test because I feel the test won't help them. I think maybe sending them to a certified arborist is a way to go? If so, any recommedations? I'm in Oakland County, MI The damn trees should never have been planted the way they were to begin with. HELP!
