5. We have areas in these parts that arr what they call pan rock. Hard clay like -good for moss to grow

The top soil deteriorates and grass won't grow only moss.

solution is 5 to seven 7 inches of good top soil compacted ,lime spread and than seeded. Just adding dirt over the top is not good enough.
That is why you do not hear back from the garden guy.

Now than if you want to resolve the issue, call your local garden nursery and ask for a consult on that problem in your specific locality, they have the products to resolve the issue including top soil if it is required.

A solution might be throw down some good top soil and lay sod. Again products sold at yer local garden nursery.Call them ,consults are free.
