14. When people would bag their leaves and leave them on the curb
My Mom would go collect the bags and use them to mulch her flower beds. I'm talking 50 years ago before many garden centers sold fancy mulch. Most of the people in town kept their flower beds raked clean and spent a lot of time pulling weeds. Mom's flowers almost never needed weeding though she'd have to pull up some oak seedlings every so often. And her flowers and shrubs always needed less water and fertilizer to look great.
