One thing to note about this weed killer is that it doesn’t work especially fast. To kill the roots, it needs around 3-4 weeks. While the weeds do start to wilt within a few hours, it takes 7 days before I actually felt the weed killer was working! Despite the slower results, it does work as well as others on the market, and it’s very easy to use. Location of the weed is also important.
