It's September and it's beginning to cool down, when is a good time to aerate and put down some seed? I like to detach in the spring followed with a spring feeding but I've noticed my lawn could use some more seeding to encourage a thicker lawn. I thought of detaching in the spring aerating in the fall. -Do you believe that is unnecessary and too much? I also thought about adding a yard of loam to my front yard,after aerating just to encourage a better lawn and promote the new seed. -Is loam unnecessary or will it aid the new seed and the established lawn? Any advice or opinions would be greatly appreciated.
