With the turn to fall weather coming this weekend, is it too late to throw grass seed down in a yard with a thin lawn? It is a relatively small front yard as it is a townhouse, and the yard gets full afternoon sun. In the backyard, I put down a large amount of grass seed, new lawn fertilizer with weed preventative, and covered it with straw last weekend. The seed has germinated nicely, and is now almost 2ish inches in height.
