    This may have been asked many times but i am going to ask again. When is the latest date I can put down preemergent on my lawn. This is not for a customer, it is for my own house. I live in south-eastern Michigan area.
    Thanks for any help you all can give me.

    Crabgrass does not germinate until soil temps reach 50 degrees. I would say you have until Mid-May.

    Soil temp was 52 in my front lawn this afternoon. Dayton Ohio.

    No crabgrass germination yet but I am switching to Diminsion for any new customers next week.

    Ground temps must average 55 degrees for 72 hours before crabgrass will germinate.

    What is your recommendation for crabgrass pre emergent? Pre-M or Dimension?

    If crabgrass hasn't germinated yet in the midwest I would advocate Pendimethelin as it controls more summer annual weeds than dimension. If you have single tiller crabgrass, then I would recommend dimension.
