Fall is the time of year you can be a heartbreaker without remorse. Love 'em, then leave 'em. Be a landscape Casanova or Cleopatra with a lawn rake and a lawn mower. Shower those favorite leafy shrubs and trees with your attention and affection from spring through summer and then, when autumn leaves start to fall, mulch them into your lawn. No tears will be shed and your lawn will love you for it.
