    Doveweed

    By Travis on 07/29/2020

    Got overrun by doveweed last year, but Magnum took care of about 90% this year with Celsius taking care of what did pop up. Can't wait to see how well it works in year 2.

    Spend More, Get Less

    By John on 04/28/2020

    Put this product down following instructions exactly. 2 weeks later, my first nutsedge is popping up. Save your money and buy Sedgehammer Plus as a post emergent.
