Hello experts!
I put down about 3 inches of top soil over a lot of my back yard - about 400 sq. feet. Then I put a monstrous bag of Scott's Grass Seed down.
I seeded on May 3rd. The grass started coming up very quickly (within 7 days) , and looks very good. However, there are patches where there is no grass, and is simply earth - even though I *know* there has to be grass seed there as I put down a LOT! lol.
My question is : Should I go in and re-seed these patchy areas ? I've posted 4 pictures for a better idea :
