I live in SE Wisconsin, near Milwaukee. Late this fall, I seeded my lawn with Elite Kentucky Blue Grass cultivators. I had hoped to do it sooner, but it took longer than I would have liked for the yard to be ready to seed. I planted in the middle of September or so. By the middle of October, I had ok germination (very thin, but most of the yard). It never really grew at all after germination. I believe it was establishing the root system.

The question that I have is that because of the smaller hills in my yard, and the fact that KBG takes a while to sprout, and now after it has sprouted, since the lawn is still so very thin, I have several erosion tracks. Some are worse than others.
What should I do about it now?? Rake across them (perpendicular to the tracks) to remove them? I do not want to tear up the little bit of grass I have, so am reluctant to do this... Unless this is the best option. Wait for the winter freeze, and address it in the spring?? If so, what to do then??

Thank you for your help, it is MUCH appreciated!!!
