Although we have done lawn redos many,many times over the years, would like opinions on this. Customer wants lawn redone on a 3 year old home. Currently consist of very little grass, mostly dormant weeds, on a two acre site. Which method would you guys likely use: -kill existing lawn using weedkiller,aerate, fertilize and overseed with Fescue/Ky Bluegrass(works well in our area) -kill existing, till with tractor mounted tiller, further level with soil pulveriser, fertilze, then seed. I know the method I would recommend, how about you?
