How soon after a lawn is sprayed can you dethatch?

    Self explanatory. My spraying sub will be spraying a property of mine & the client wants it dethatched (via jrco, not a "true" dethatch but just to remove the immense amt of dead grass), then aerated then overseeded. I know to wait a few weeks on the overseeding but it will be sprayed tmrw morning/early afternoon and I'm hoping that I can dethatch & aerate the lawn on Friday mid afternoon, giving the product a solid 24 hours to take affect. :confused:

    You're spraying guy would be the one to ask, inthat it depends on what is sprayed and whether dethatching is going to interrrupt the weeds soaking in the chemical adequately... in general 24 hours should be plenty...
