My question regards which gets better results aerating then overseeding or dethatching then overseeding. The answer that if it has thatch dethatch and if its compacted aerate is an obvious one and if thats the only one then fair enough. Im thinking of a lawn which is somewhat compacted and has not a bad thatch problem, perhaps half and inch or so. In this case im wondering how to get the most out of the overseeding if the customer wants to pay for only one or the other. Thus far I have been aerating yearly prior to overseeding and only dethatching if there is a serious thatch problem which seems to be rare here. Even if you have thatch buildup wouldnt it be easier to aerate which also helps fight thatch then do a dethatch with the cleanup that intails? Im looking for re-enforcement or for people to say how amazing dethatching is in improving a crappy lawn.
