On The This Old House Hour, Roger is always saying that for "the last mow of the season" you should:
  • Cut it short (or is it long?)
  • Use the bag, instead of mulching the grass
  • etc.

So is there a way to determine (e.g. first frosty morning) that you're making the last mow of the season? Or since it's mid-October, should I just assume every mow is the last one?
