    Is one way to spread seed better than the other after I aerate this fall?

    I haven't done any slit seeding, but think of it this way, with aerating AND broadcast seeding you're performing 2 tasks. So you not only get the benefit of overseeding, but you also get all the benefits that come with aerating a lawn.

    Others that have experience with slit seeding can better tell you the advantages of that.

    IMO, that is a lot of damage to a cool season lawn to
    both core and slit-seed in close time proximity.
    There ARE warm season grasses that thrive on that
    kind of mechanical beatings but I guess I'm just not
    comfortable with that.

    Seeding after aeration will NOT have the same
    germination rate as slit-seeding. You will have some
    portion of your seed germinate if you spread it after
    aeration but again, somewhat less then the process of slit-seeding which after all is what that process is designed to do.

    That being said, without a long winded discussion and
    back and forth's, I prefer to aerate in the fall and slit-seed
    in the spring. That is me.

    But i do also always spread seed after I do any mechanical
    renovation to the yard like aeration in the fall.

    It's a your way or my way kind of thing. You can't go wrong by over-seeding a yard once or twice a year,
    I mean grass plants do senesce.

    I prefer broadcast seeding after multiple passes of aeration.
    A slitseeding in the spring afterwards if it warrants.
    Just my thoughts...............

    Tom, just to clarify, I wasn't suggesting both. I suggested aerating and broadcast seeding rather then slitseeding.

    I understand that, your answer was fine.
    I was responding to his question which was
    what was better "after I aerate this fall'
    No foul.

    Ah Ha! I now see that I read the original question wrong.

    I agree with you then, both is too much.

    Thanks for the replies. What I gather, please correct me if I'm wrong, if I want to overseed this fall after aeration, I should use a broadcast spreader.

    Two other quick questions:

    1) Should aeration be done once a year?

    2) If so, should you overseed each time you aerate, or is there such a thing as putting too much seed down?

    I don't see how aeration once a year could do anything
    other than help your lawn. I suggest doing so.
    I always throw seed down when I mechanically
    renovate the yard. (AERATE OR DETHATCH)
