Kills crabgrass and weeds

[This review was collected as part of a promotion.] I tried this product for my honest review. I tried it recently on my lawn as we've been getting lots of weeds and crab grass. We've been trying everything to get rid of it, but nothing really seems to be working so thankfully when I got this, I tried it on everything. It was very easy to use and I saw the results within a few days. I'm very happy with this product.

Decent

[This review was collected as part of a promotion.] I had my landscapper used it on the grass. I was hoping it will take care of the weed too but it doesn't, just get rid of the crabgrass. It's effective. Works fine. Easy to use
