re and sub: So are you using pre-emergent on your own lawn? I don't like pre in any form (even corn gluten) applied in Spring because I believe it inhibits root growth of the grass plants at a time when they should be optimizing growth. A thick stand of grass prevents most weeds.
Edit: Sorry I notice that you do use corn gluten on your own lawn. So do you use it on customer's lawns?
