About this item
- 4L POWERFUL WEEDKILLER WHICH KILLS TO THE ROOTS – Growers Own Weed Killer Extra Strong is ideal for tackling unwanted vegetation across paths, patios, borders, & gravel areas. This glyphosate weedkiller is ideal for routine garden weed control, seasonal maintenance & spot treatment of annual & perennial weeds, including grasses, docks, nettles, willowherb, bindweed & more. The concentrated formula delivers coverage of up to 1600m² when used as directed. For use as a home garden weedkiller.
- EXTRA STRONG SYSTEMIC FORMULA – This weed control formula works systemically, moving through the leaves & throughout the entire plant structure to target both visible growth & underground root systems. It’s inactivated upon contact with the soil & is broken down naturally by soil organisms, leaving no lasting residues. Designed for the effective control of annual, perennial & biennial weeds, it helps prevent regrowth by tackling the root cause rather than simply burning back surface foliage.
- FAST VISIBLE RESULTS WITH DEEP-ROOT ACTION – First effects may become visible from just a few days after application, with complete weed control typically achieved within up to 4 weeks, depending on weed species & weather conditions. As the systemic weed killer works through the plant to the roots, it helps deliver longer-lasting control. Cultivation can take place after at least 7 days, while tough weeds such as ground elder may require a second treatment after 3–4 weeks if regrowth occurs.
- OPTIMISED FOR RELIABLE WEED CONTROL IN OUTDOOR SPACES – Specially formulated for use on unwanted vegetation in domestic outdoor spaces, making it ideal as a weed killer for driveways, patios, pathways, gravel areas, fence lines, around sheds & other non-crop locations. Absorbed through actively growing foliage for best results on healthy green leaves. For optimal performance, apply during suitable weather conditions; rainfall within 6 hours may reduce effectiveness & require re-treatment.
- EASY TO DILUTE & APPLY WITH STANDARD GARDEN SPRAYERS – Simple to apply using either a hand-held sprayer or knapsack sprayer as a medium-coarse spray. The concentrated formula should be mixed with water before application & sprayed lightly onto weed foliage until just before run-off. Suitable for amateur home garden use & allows future planting approximately 7 days after treatment once weeds have died back. For best results & safe application, always use as directed on the product label.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
