    One of my new customers wants to kill all of the existing dandelions and prevent new ones from coming back. Same goes for all his other broad leaf weeds. I suggested in mid feb. that he needed to aerate and apply a pre m. And he refused. Said that weeds weren't bad in his yard.... LoL. How far from right was he. So now he wants me to apply a weed and feed to take out the dandelions... I am new to the whole idea of fert pre and post m and all. But it is 70 percent rain friday, 60 percent saturday and he would like it to be applied before it rains. Which is fine for a granular weed and feed. But will it work.

    Thank you,

    P.S. i plan on getting a friend to do it for me who has the proper equip and experience.

    Um, nope.

    On the weed and feed bags that I have used, they clearly state-Apply immediately AFTER a rain or early in the morning while there is still dew present. It will also state DO NOT WATER for 48 hours.

    As far as the prevention, I don't like to aerify and then pre-m, I like to wait another 6-8 weeks to punch holes.
    Very intelligent of you to get someone with proper equipment and experience, just make sure he is licensed too. Ask him questions too, it will only help.

    Personally, I prefer liquid apps to rid broadleaf weeds etc.

    A friend huh...:laugh:....Well just a tid bit of advice, if you aerated before the 6 week barrier window, then you might as well kiss your coverage good bye.....As for when to apply weed and feed, you need 48hrs after a good rain or a good watering cycle of dry weather to allow the weeds to suck up the weed control and work in....if you put it down before it rains, it will just wash away your coverage and wash any dust particles off the folage. But make sure the lawn is wet so that the weed control can stick to the folage.

    Okay. He called me and agreed to a liquid post emergent. Quick question could i just mix some hi-yield atrazine in my atv boom sprayer and apply it after the rain with a surfactant??? It is centipede grass.....

    Wouldn't that be a trick and wish it were that simple. Are you licensed?

    Don't try to do this yourself. Call a licensed lawn care company and sub it out or you will be sorry. Dead grass, fines, unhappy customer, ect

    This suggestion was a mistake on your part.

    A "pre-m" applied to the lawn will only prevent non-germinated annual weeds.

    Dandelions are PERENNIALS.

    Weed controls...both pre and post-emergent.. will work only as far as the following law will allow them to:

    Law of Weed Control in Turf

    The first line of defense against any 'weed' in any stand of turf, is strong competition in the form of dense, well aerated grass, that's in soil that's still biologically alive.

    Actually, aeration won't affect the barrier...it will still hold. As long as it wasn't aerated to the point of being roto-tilled. There are some good university test articles posted on here about this.

    I must be mistaken but doesn't atrazine act as both a post and pre. But mainly used for a post emergent? If not what should be used on a centipede lawn to remove broad leaf weeds. That won't harm it. That rules out so much stuff. Due to 4,2 D being in just about all chemicals.
