I could only think of 3 reasons for aeration(plugging) and ridiculed every other idea for it, especially seedbed... But I read a post on Lawnsite and decided that since I had the aerator in my hands, that I would beat up this piece of ground until... I hurt... Well that single post made me think about something, that I'd never thot about b4... When one is confronted with a tough area in which, compaction, puddling and shade come together, to prohibit any kind of grass to grow... What do you do??? The answer is: Use the aerator like a tiller and loosen the soil to the point of soil viability , then level and overseed... Turns out to be a pretty decent seedbed after all... Who else has had any luck with chronic problem areas like this ?? And: Has it worked for you???
