it works much better than others
4 Stars
it works much better than others
I used other less expensive brands in the past and they were not as effective. You would see some browning and they would bounce back. But with this, it went brown from tip to toe in 3 days. And you only need to spray it on the leaves. I would stay far away from any garden vegetable though.This also will kill any grass near the weed, don't spray too wide or you'll end up with dead spots in your lawn. Minus one star, not as targeted as I thought it would be. One option is to use Scott’s fertilizer, it has a weed killer component, sprinkle the grass fertilizer in the leaves. Or just yank the weed out, use a long flathead screwdriver to dig into its root.
