    I sprayed today pre emergents today and about 8 hours later it rained cats and dogs for about an hour. Will this just wash the emergents away? Or will it soak in?

    someone please respond !

    most pre-ems require irrigation/rain to work them into the soil, unless it was like some kind of flash flood, you should be just fine.

    Pre emerges are rained in and watered in to activate them. I dont think you will have a problem either
