    Worked a little too well

    By Bryan on 04/09/2016

    Verified Purchase

    Applied this product to my lawn using a hose-end sprayer. Mixed and applied per the instructions. It took a few days, but I've seen a noticeable change in the few dandelions and clovers that had popped. All are shriveling and dying. One thing I did notice though is that the product killed off some of my grass as well. At first just the ends were turning brown, but now entire patches of grass have died. My yard is a fescue/blue grass mix that is supposed to be safe from this product. Probably would not buy again due to the damage to the grass. Three stars because it did a great job with the weeds, but also did a number on my grass.

    Wild Violets

    By Jerry on 08/16/2015

    I have given a 3 star rating to Speedzone because I'm still in the process of attacking this tenacious weed. I tried SZ in the summer and it only wilted the weed but killed very few. I have read that the fall is a good time to apply SZ because the violets are taking in food for the winter months and more easily absorb the SZ. My advice is not to apply until the fall or spring when the violets are actively growing. To be continued.

    Did not work as expected, could be my fault

    By David on 09/07/2018

    I used Speed Zone on what I thought was Virginia Buttonweed. The weed turned off color for a few days but came right back. I tried 4 Speed XT first with the same results. Currently I am three days into a Tenacity treatment. I am not sure the weed is Virginia Buttonweed. I may have misidentified the weed, so I really can't fault the Speed Zone.
