I live in the Philly area. In late fall I decided to patch some lawn bare
spots using a ryegrass mixture. I seeded bare spots and covered with about
1/4 inch topsoil as I usually do (usually get good results).

Howver, I think I did this too close to the cold weather. It turned really
cold a week after I seeded, so no germination. My question is: Will the
seeds survive through the winter and germinate this spring, or should I
reseed all over again?
