    hi everyone -

    I am looking to overseed my lawn on September 12th (rented aerator to help). I just received another soil report from cornell and my ph is high at 7.3 in the backyard and 8.0 in the front yard. They are recommending that I add elemental sulfer in the fall and the spring and retest the ph in a year or so.

    Since I will be overseeding in a few weeks, should i apply the sulfur now or wait until late fall???

    Also - with overseeding should I put down fertilizer when I throw the new seed down or wait a week or so to hinder old grass growth?
