Lawn company already put a pre-emergent down but I've got some really bad spots of bare dirt thanks to last year's heat. Scotts told me I could rake up the bare spots to break the pre-emergent. Plus temps here have unusually been getting down to freezing so I've had to wait to put seed down. Would the patch stuff help by letting the seed germinate? But damn that stuff's expensive for the area I need and the spotchy aspects of my bare areas.
