Greetings, This forum is great! I am not a lawn care professional, however I thought there couldn't be a better place to get advice. I have searched the threads a bit and came up empty handed. Please help! I am in the process of installing a new lawn. I Killed the existing weeds and grass, tilled, raked, and grated the area in preparation to lay sod. I had planned to lay the sod today but have been delayed by 3 days of heavy rain. In the last few days some weeds have sprouted up, most likely crab grass. My question is, how should I handle these sprouts? Should I wait for a dry day and hit it with some herbicide? Should I remove them by hand? Would the herbicide effect the sod? I am afraid if I just sod over the sprouts, they will intrude on the new grass. Thanks for the help. Here is a photo of the prepared area.
