    Sure it is hard to tell without some serious test work done, but I am not comfortable mowing after a granular Pre-Em app until there is a least some rainfall. Anyone with accurate knowledge on this?

    It is preffered to mow relatively short before applying prem. It needs to be watered in pretty quick as it will break down when exposed to UV
    I do not have much luck with Granular PreM products.

    I never worry about it. What happens if you cut a granule in half?

    You double the number of granule's but reduce the mass of each one...:laugh::waving::drinkup:

    I'm not sure it matters. If you put down slow release, it will rupture the encapsulated granule and it will no longer be slow release.

    IMO; mowing after a granular application isn't smart. The granules get sucked up into the deck and discharged with the grass rendering your intended product distribution moot.

    We have a lawn that requires bagging, according to the h.o.'s desire... I unloaded grass clippings with enough granules mixed in to actually notice it... :)

    Up north pre em goes down before guys are even cutting grass so for us it doesn't matter. I am thinking of spraying my pre em next year less break thru.

    Why do you pre-m so early, when CG doesn't germinate until well after the cool-season grasses have started growing again??? CG is a warm-season annual...

    Crab Gass is not the only weed controlled by PreM
