Re: Aerate or Power Rake First???
Most people don't really have much of a thatch problem. A thin layer of dead stuff in not a problem, just the natural decay cycle. I think it is a bigger problem down south.
Your in WI, right?
As I understand it, aeration is very important. Soil gets packed down and roots can't grow, moisture does not soak in as well, not as much activity going on to cause the thatch to decay, etc, etc, etc.
I got the plug aerator from Home Depot (or Menards?). You put some weight in it and pull behind the garden tractor. So I do it a couple times a year, and it seems to be helping. The areas that get walked on and compacted I go over a bunch of times.
