A systemic weedkiller, which kills both the weeds and the roots, so they won't grow back. Results are visible just 2 days after application, and weeds will be dead in 21 days. Weedol will kill all garden broad-leaved and grass weeds, most of which will be dead after just one application. The formula degrades in soil, allowing replanting and sowing soon after application (1 day after light spraying, 7 days after dense spraying). Best used between April and November when weeds are actively growing. Perfect for use on gravel, paths, drives, around sheds and greenhouses, along fences, ground clearance before autumn or spring digging, as well as around the base of roses, ornamental shrubs, trees and under hedges (provided they are established, with woody bark). This pack treats 29 square metres of brush weeds, 34 square metres of perennial weeds and 37 square metres of annual weed. Weedol Rootkill Plus will quickly kill all green plant growth. Do not apply to cultivated plants or lawns unless you want to kill them. For an effective weedkiller that does not affect grass, use Verdone Extra. Contains glyphosate and pyraflufen ethyl. Always read the label on your purchased product before use.
