When I overssed for my clients, I return in 6-8 weeks and do a tune-up. That is I ressed the areas that didn't fii in as well as I would have liked. I either aerate or scratch the surface with a hard rake, add some seed, and lightly cover with straw. Should I charge extra for this return trip? I make no warranty when it comes to germ. rate. I use LESCO Transition Blend seed almost exclusively. The seed has done really well for me, just every now and then there are some small bare spots. Do you folks perform these "tune-ups"? Thanks, Bill Craig!
