Im looking for advice on maintaining a yard of grass this year instead of weeds. Right now my yard is covered in weeds and is so tall I need to mow it badly. The problem is its soaking wet, I live in North Mississippi minutes from Memphis, it rains here every other day this time of year. I dont know if I should mow it then spread some type of weed killer or spread the weed killer first? And I have no idea what kind of stuff to use. Any Help?
