    I searched on this site to my overseeding and aerating question but I havent been able to find the answer. In the next two weeks, I plan on aerating and overseeding my lawn with a perenial rye and kb blend. I will cut the grass short, 2", as Ive read is recomended.

    My question is this - since my lawn grows really, how long should I wait before I perform my first cut after overseeding? If I wait two weeks, the lawn will look like a jungle. If I cut before all the seed germinates, didnt I waste money and time?

    No need to change your mowing routine after overseeding. In fact, we incorporate mowing as the last step in aerating, seed-detatching our athletic fields. It helps break up any soil plugs and heavy grass we may have on the surface. If you are using a spreader to overseed, I suggest that you take the time to work the seed down to the soil. Also, if you are using a spreader it would be a good idea to mow the existing lawn shorter than you had mentioned. If you are using a piece of equipment like a seeder-detatcher there is no need to go to the extra steps I mentioned.

    I tell my customers to not cut for 2-3 weeks. If it gets a little high, just be patient. Those new seedlings are very tender, why put added stress on them by running a mower over them just a week old?

    Ah, two different opinions. You have to strike a balance. Definitely don't mow over any larger bare areas with seedlings, just let them grow for a few weeks. As for the rest of the lawn, you can't let it get too tall. Try to mow when the soil is dry, to minimize turf damage.

    Thanks all. I will cut the lawn short, aerate, and then overseed with a perenial rye - I would love to throw in a kb but may have to wait until spring. Since the lawn, or soil, is already being treated with an organic care program, I dont intend to put down a starter fert. Thanks again.
