Roundup Ultra is a super strength concentrated systemic weed killer that kills weeds to the roots, preventing regrowth. It can be used to control most garden weeds, deep-rooted broad-leaved & woody weeds including Brambles & Nettles, trees and tree stumps. By working with a variety of trusted Range Plus Partners, we’re able to offer our customers a wider selection of products. And selective weed killers can be applied in larger quantities (lawns) as they’re only effective on broadleaf weeds and are much safer for your garden. Plants have hormones too, and these chemical hormones are linked to natural growth. Some weed killers contain plant hormones, some natural and some synthetic such as 2,4-D (Trimec). When these products are applied to the plant, the hormone is absorbed and confuses the plant’s own growth system. This leads to growth deformities before eventual death.
