    This seems to be a very popular way of overseeding. I do have a question though (imagine that). If grass seed is supposed to be "planted" just under the surface, how does it ever grow from the bottom of an aerated hole (2"-3" deep)? Or does the seed get lodged in all the cores (on the surface) and grow from there?

    Thanks for all the advice,

    Joel B.

    Because the seed isn't 3" under soil, it is sitting at the bottom of a whole. This is were you will see most of the germination. The rest of the seed makes contact with the cores and the top soil created by cores that have broken apart. When aerating and seeding, you need to plug the crap out of the lawn. I usually aerate, seed, aerate again and seed again. Really bare area, I will rake in the seed when finished.

    If the turf is very dense, then another method should be used.
