I have a rather large lawn. Most of it made it through a snowy than normal winter quite well. I do have a few spots that look like winter got the best of them. Mostly where the snow was piled up for extended periods of time. My question is. On these dead spots should I remove all the dead grass and reseed or are there still roots there that will grow back faster than reseeding. Grass is called 3-3-3, supposed to be an equeal mix of fescue, bluegrass and rye. I have the die off in both full sun and part shade. No dog. Thanks in advanve for any help.
