    I have a client that wants me to redo his front yard. Its not big at all. Less that 1,000 sq feet. The yard is a little low and he want me to bring it level with the walkway and the driveway. Which means adding about 4 or 5 inches of top soil at the lowest spot. Now, the grass that is planted there now isn't to bad, not very many weeds at all.

    My question is, Do i need to spray round-up on the existing grass and then rototill it in and then add my top soil? or can I just put the new topsoil over the existing lawn and compact, seed, fert, and call it a day?

    I'm from Pennsylvania.
    Also, When is it to late to start to try growing new grass.

    As I keep reading this I'm thinking rototilling is the way to go.
    I already check with old threads and could not find any like this?
    Thanks TBLC

    if you have to add 4" of soil then there is no need to till. that is more that enough to seed a new lawn in.
