Hi all I laid down a new lawn of St augustine sod 4 weeks ago and I want to know how long I should wait before I can mow it for the first time? It's thriving well it's the greenest yard in the neighborhood but it's already at 6 inches in some areas. Is 4 weeks to soon to mow. I wanted to wait 8 weeks but if I wait that long I'm afraid I'm going to have a jungle.
