I am a new user and i am not sure if my first message got posted. If any one can help, I have questions about my new SOD lawn that I have just put in(Bluegrass/Fescue). 1-How long and at what times should I water? 2-Parts of the lawn are mushy(2-4inches of topsoil), will it firm up? 3-When can I walk on it? Thanks for your help.
