I have a customer that has requested overseeding. He plans to move in the fall so he wants to spruce up the yard. I know that fall is the best time to do this, but he wants it done. My question has to do with weeds. When I first looked at it the weeds were at an acceptable level, but now(two weeks later) the dandelions have spread and a few other broadleaf weeds. Should i concentrate on getting rid of the weeds first, Then overseeding later. any help would be appreciated.
