Having been in my house for 5 years and not wanting to do the quick, and I believe dangerous, fix of chemical treatments on my lawn, I have located and hired a local Organic Lawn Care company. I was wondering if anyone could offer insight as to whether I should do an aeration and seeding before the first treatment. I live in PA and the gound is still frozen but is thawing. I did slit seed last fall but the lawn is a mess (lots of clover) and needs much attention. Thanks for any help.
