    For those of you that go by the ground temps the way you're supposed to before applying pre-m, how do you get the temperatures of the ground?

    If i'm not mistaken, isn't it 55 degrees soil temp when you are supposed to have the pre-em down? At least I think that's right for Barricade...

    I have a soil temp probe but I always cheat and go out and start doing my apps when everyone else does. I figure they can't all be wrong, lol

    I've read by 55 F for pre em, that's what is on the Barricade label. I start a little early because it takes me a 4 -5 weeks to get all my applications done and here the soil temp can change rapidly. One freakishly warm week and it can go from 45 to over 55.

    Soil temp has to be sustained at 55 degrees for a few days before crab starts germinating.

    Always better to start early and know the average date in your area that 55 is normally sustained. Our cutoff in this area is about March 15.

    Everyone always speaks of crabgrass - What about the germ temp for most summer broadleafs?

    :laugh:
    They sell them at lesco also.
    55 degrees is the number for me at a two inch depth for a few days and away fro heat reflective surfaces.
