    Alright, I asked this question in an existing post and didn't get much attention, so I decided to start a new post. I've had several requests to aerate, verticut, and overseed some lawns. I've also had some dethatching requests. My question is that it would seem wise to dethatch before overseeding, but I think it's too hot here. If I don't will the overseeded grass stand a decent chance?? If I wait until later in the year to dethatch, when should I do it, and will it hurt the new grass??
    thanks

    dethatching is done in the spring........Aerating can be done in both spring and fall but it is more beneficial in the fall. Overseeding is done in the early fall. I usually start around the 1st week of september up until the 1st week or october. Anything after that you start dealing with possible snow and real cold temps.

    I don't know much about overseeding, so please forgive any stupid ?'s.

    As far as overseeding goes, are you guys applying anything for moisture retention? Straw, penn mulch, etc.?

    Is slit or verti-cutting required, or can the overseeding be done in conjunction with aeration?

    overseeding after areating is the way to go. Even better if you have access to a slice seeder. I usually aerate, slice seed, topdress and then drag around a screen to break up the plugs. Looks crappy at first but wait till spring......best looking yards around

    I aerate, overseed, then dethatch, in that order.

    I always thought I would lose at lot of seed in the thatch. Especially when I sucked up the thatch with a bagging mower.

    I was told that dethatching would "shake" the seed down into the ground. Also the dethatcher will break up the plugs left over from the aerator.

    I have aerated and then seeded only, but didn't get a good result.

    I always do this in late September, to allow a few good weeks for the new grass to take off.

    All of my advise goes from a golf course super. He has a degree.
    He seemed to know what he was talking about.....I had to cut the thickest grass in Oct.

    rmartin:
    I'll actually be "aera-vating" so I won't have plugs to break up. I guess the real point of my question is:

    Is the slice seeder step NECCESARY?

    Thanks.

    oh yeah, moisture retention?

    slice seeding is the best way to go. You can just spread the seed with a spreader too. It;s up to you. I prefer the slicer.......and no i do not use any moisture retention. really no need to if you have a good yard to begin with
