A lady called yesterday about lawn aeration. I get there, measure out about 6000 sf. A large part of it has been a dog pen for about a year now, and is just dirt. Very hard dirt. Another part had a blow-up pool this summer, so it is hard and dead as well. Do I need to aerate and powerseed? I've read a lot here the last few hours, and a few have talked about just aerating then broadcast seeding. I don't think this will be the way to go for me. When aerating, is it best to make two (or more) passes in an "x" pattern, or will one be enough? And with power seeding, does one pass do, or do you use the same "x" pattern? I apologize for the seemingly ignorant questions, I've never done either of these before and I want to get it right. I have had one person tell me that he just powerseeds without aeration, because the knives of the seeder do enough aeration. Is this even close to right? I just don't want to make an @$$ out of my first aeration/seeding job. Thanks for any help!
