Roundup Ultra is a non-selective, translocated weed killer that is absorbed by leaves and freshly cut, woody surfaces and moves throughout the entire plant, above and below ground, to control annual and perennials weeds, including grasses and deep rooted perennials weeds. It also controls standing trees, newly cut tree stumps, tree saplings, brambles, bracken, nettles, Japanese knotweed and other tough and woody weeds.You may see some visible yellowing of the leaves and stems after 48 hours. But that is just on the outside - on the inside of the weed, the systemic action takes Roundup to all the weeds growing points to kill the weed from the inside out. Importantly, because roundup kills the roots, you know that the weed is not coming back.
