When I was growing up lawns were meant to be played on....now people treat lawns like priceless heirlooms. I've never been a fan of applying or having someone else apply all sorts of chemicals to a lawn.
About 20 years ago a neighbor(since moved) became obsessed with his lawn. He would spend 10-12 hours each day working on the lawn. His lawn was ELITE golf course level but it cost him thousands of dollars each year. He was draining his savings. After years of applying chemicals to his lawn his health(including mental health) headed downhill quickly
