Anyway, you can apply broad leaf weed killer right now, but since the stuff is well established it may not be as successful. Doing so in the spring and early summer is usually more effective because the plants are not as tough.
Roundup is SYSTEMIC. It kills everything, grass and broadleaf weeds, so don't spray it in your yard becaue you will end up with dead spots everywhere you put the stuff. There are some sprays that say they don't kill grass, in which case they are broadleaf herbicides. With a large yard, it's expensive to do it that way, but you could apply now.
Aerating and overseeding are great ideas. I posted my opinion earlier about doing the overseeding while there is still some warmth, like late summer so that you will get germination and growth for the fall (which is when cool season grasses thrive). Aerating, I do that later, after some rains have shown up and softened the yard. Makes the job a lot easier for you and the aerator.
Well, to be honest, I don't remember what we had decided that it was. Even with the pictures, you weren't completely sure, IIRC. I know henbit was in the discussion, but there were others we discussed as well. We have a pretty decent sized yard (~1 acre). I might buy the broadleaf herbicide for the normal weeds that pop up in our lawn. I'll probably wait until the spring to kill off the stuff that is blanketing my backyard. I thought it would be smarter to aerate before overseeding so that the new seeds had room to settle in and more oxygen / nutrients could get to it? You're saying just go ahead and overseed now and then aerate after?
