We got a call today from a gentleman who has just recently had allot of construction done at his house. He told us he has about 9" of sand in his front yard and he wants us to make it so that grass will grow. I have no idea what to do in this scenario, but it seems like it would be allot of work? What is the best way to go about doing this? Till in top soil? Or try to remove sand then add topsoil? Anyone who has any type of experience with this I would really appreciate the comments.
