    When should i apply my Pre-M for Crabgrass? I live in the Fort Worth area.
    I think i'm in zone 8 but i'm real close to zone 7. I will be using DG Aquacap.
    Should i do the full rate now or do a split app.

    Use soil temp, not zone for timing.

    Do a search on this site for numerous discussions on subject.

    Growing degree days, or when the forsythia turn green... not when they flower.

    Hey guys I dont mean to change the subject, but I need some advice...

    I operate out of Tulsa, OK. I have a client that has decent size sticker problem in his back yard. They are everywhere. Of course they are dormant right now. I have not been doing the weed control part of the business for too long (only a couple of years). Any suggestions as to what to apply to help control them when thinigs start to come back this spring? I was thinking of applying some round up, or possibly Three-Way from Lesco. And of course I am going to hit it with a couple of rounds of pre-m. Any other suggestions? The site in question is about 1500 sq ft.

    Sticker.... that sounds like a local name for some type of weed. Never heard of it. Do you have another name for it?

    Start a new thread instead to ask your question instead of hijacking another one. You'll get a better response anyway if you do.

    When you say pre-m do you mean Pendamethalin? or do you mean a pre m in general, the reason I ask is products like barricade/stonewall you can go out alot earlier especially if youre gonna be doing split apps.

    Sticker works good when you think it might rain
