OK heres the deal. I do all of the landscape and lawn maintainence for a subdivision. A few of the houses were leased out and the people there never did water there lawn. It has been dry for well over a month and very very hot and the sod has completely died on a lawn that the people just moved out of. Heres the question... Can i just seed over that lawn and fertilize to get it to grow? Or do i need to rip all of the sod out and re install sod. Thankyou!
