I'm in Ct and have a horrible lawn. There are too many types of weeds to name from course fescue, to clovers, to ivy. My original plan was to dethatch really well, then rent a slit seeder to put new seed down, try to choke the weeks out and use a pre emergence next year. Instead I'm thinkng about using roundup on the entire lawn, using a power rake to get all the grass up, then use a slit seeder. Follow it up with a pre emergence next year. My lawn is growing like crazy and we just had many in. of water over the last week, I figure now is the perfect time to roundup. I have a bunch of questions.. How long after the roundup should I wait to plant grass? Should I wait for germination of new grass/weeds and roundup again? Is it getting too late this year to do it? How is Lesco Brand Double eagle supreme for my area? Can I use a slit seeder if the ground is wet? Thank you very much for the help.
