about a month ago i completely redid my lawn and seeded it with a rebel tall fescue blend. it has grown quickly and greatly. it is a little thin and patchy which i'm sure is some of the reasons the weeds have come in. i'll have to overseed it to thicken it up. I'm not sure where the weeds have come from, i'm guessing they must have been in the straw i put down over the seeds. those bails have sitting outside for over a year so i thought they'd be okay. anyway, here's a couple pictures of what they look like. they are really thick in a couple spots and just here and there throughout the whole lawn. it isn't a creeping weed. they are individually tap-rooted with about 2-5 leaves per weed. What is it, someone said mallow? and what do you suggest to do on such a new lawn, both for the weeds and to thicken it up?
