As I pick up more and more customers in this business I would like to be able to provide this service for them,but actually know very little about it.All I know is what I do on my own lawn.Every spring I apply Scott's Turf Builder Plus to my yard.I never aerate,thatch(dethatch or whatever-don't even know what it is or how to spell it),apply pesticides or anything else.I just put out the Scott's one time(probably twice what they recommend) in the spring,then cut it once-a-week(at a very low setting) and then water it when I think it needs it.I rarely see a lawn anywhere around town that looks better than mine.I have zero weeds.Common sense tells me that if I apply this product to my customer's lawns their's will look as good as mine IF they water it properly because we're all in the same area.Now I'm only talking about centipede grass but that's what the majority of people have around here.Is it really this simple?How much education do I need in this area?
