I have a small area (about 20 ft by 8 foot) patch in the front of my driveway that I want to fix. The builder planted grass 8 yrs ago Not sure what he did (how much topsoil he put, what type of grass he put, etc) butall I have is hard hard lawn, lots of rocks, and weeds, with grass here and there. I used tool today to rake/scrape all the dead matter away and filled like 3 garbage bags with leaves, stones, dead stuff, etc. I also softened the area since it was rock hard. It is 'low' and I want to build it up a tinge before p lanting. can I just dump 2-4 inches of topsoil on this area, and plant seeds in that? Do I HAVE to kill t he weeds first? I really want the grass quiclkly. I'm in NY. Would this work? I'd love some suggestions. Thank you.
