Weed and feed on new grass?
On top of an well established lawn I spread 4" or so of top soil to raise a low spot. Then I planted grass in early May. It came in pretty good but there are weeds. Pulling them out by hand helped some but as the summer wears on, there are more.
I seem to remember something about not using weed and feed until you cut new grass several times. My wife says, "not in the first year".
The area of the lawn is shaded by a big tree till about 2:PM and is in direct sunlight for the rest of the day. The lawn is watered regularly via an automatic sprinkling system. I'd like to put down W & F as the rest of the lawn needs it too.
