Roundup Ultra Tough Concentrated Weedkiller - 1L

Ultra Tough Weedkiller for Stubborn Growth

When weeds start taking over paths, patios or borders, you need something that won’t back down. Roundup Ultra Tough Concentrated Weedkiller is a powerful, professional-strength solution designed to tackle even the most stubborn growth, including woody weeds, tree stumps and saplings.

This tough weedkiller gets straight to work, killing weeds right down to the roots so they don’t come creeping back. It’s ideal for clearing overgrown areas, preparing ground for replanting, or even full lawn destruction when you’re starting from scratch. You’ll see visible results in as little as 48 hours, making it a reliable choice for serious gardening jobs.

Because it’s a concentrated Roundup weedkiller, a little goes a long way. The 1-litre bottle makes up to 100 litres of solution, offering coverage of up to 3000m² depending on application. That makes it a practical and cost-effective option for larger gardens, allotments, driveways and commercial spaces.

It’s suitable for use from February through to November, giving you a long treatment window across the growing season. Once applied, it degrades into the soil, so you can replant treated areas once the weeds have fully died back. The child-safe cap adds extra peace of mind when storing it in the shed or garage.

If you’re dealing with deep-rooted perennial weeds, brambles or unwanted saplings, this Roundup Ultra Tough weedkiller is built for the job. Strong, dependable and easy to mix, it’s a must-have for keeping your outdoor spaces under control.

Ideal for patios, driveways, fence lines and large garden clearances.
