I'm a new member in se Pa with a lawn that needs a good amount of work. I have grubs in the front yard, very thin turf all around and a weed problem, mainly buckhorn plantain. I've pulled quite a bit of it by hand but this seems futile as it keeps returning and spreading.

I am planning to pull as much as i can and apply a weed and feed product.I would like to stay organic if possible.

Any suggestions?
