Thinking about letting one if these companies do my fertilizing for a year to see if it makes a difference. I'm looking for actual experiences with these companies good and bad. Tru-Green: 5-6 applications/yr, $55/each app. Fall aerating: $100. Scott's: 6 services/yr, $79.80/service including a fall aeration. OR 5 services/yr, $68.45/service plus $187.00 for fall aeration. I've heard good and bad about each (like any business) and am looking for opinions. Thank you, Joel B.
