i am completely new to the aerating process but would like to educate myself entirely. i was told in a previous post that after you create the holes and the plugs are all over the ground, you just leave them there. i thought you were supposed to rake them up of something. so you just leave them there and let them melt back into the soil? doens't that make the yard look hanous??? how long before the disappear? what are your guys' rates for aerating? charge by square foot or no?
