Spring clean up here in the north just started. I got 30,000 flyers going out over the next two weeks (this sunday and next), primarily for Power raking. I also advertised Aeration but I don't have an aerator. Worse case I rent one out and do everyone at once but.. I thought I read here that first thing in spring isn't a good time to aerate anyway, something about giving the weeds a head start. Is this true and if so can anyone expand on this? I'm looking for a legitimate reason to delay it for a month or so, so I can buy one.
