bought a new place last year, trying to get the weeds under control. Did weed and feed last spring, had some tree work done to let light in, and aerated/seeded last fall. Did weed and feed again last month and got things looking pretty good, but still have some weeds I want to get rid of. Do I weed and feed again? Skip the feed and put out some preen just for weeds? I have no clue what i’m doing here, I’ve always cut close and tried to kill it in the past.
