I am looking into doing some lawn renovations and fall clean-ups this year. which one comes first, cleaning up the leaves and disposing of them in the fall, OR overseeding? I know they both get done in the fall, but approximate timing of this will really help out. Thanks! Also, on overseeding: if you slit seed or aerate then spread the seed with a spreader, does this reduce the need for top dressing since the seed is deposited straight into the soil?
