Application Tips for Best Results
When to Apply
Apply roundup weed killer during dry weather when rain isn’t forecast for at least 6 hours. Choose a calm day to prevent spray drift onto desired plants. Spring and early autumn are ideal times for weed control when plants are actively growing.
Application Technique
Spray leaves thoroughly until just wet, avoiding run-off. Target the entire weed plant, especially the leaves, as this is where the roundup herbicide is absorbed. For best results, avoid disturbing treated weeds for at least 7 days to allow the product to work through to the roots.
Safety Precautions
Always read and follow label instructions carefully. Wear appropriate protective clothing including gloves. Keep children and pets away from treated areas until the spray has dried. Store products in original containers in a cool, dry place away from food and animal feed.

Frequently Asked Questions
What is Roundup weed killer used for?
Roundup weed killer is a versatile herbicide used for controlling annual and perennial weeds in gardens, paths, patios, driveways, and gravel areas. It works by killing weeds down to the root, preventing regrowth. Different Roundup formulas are available for various applications, from general garden use to specialist path and gravel treatments.
Is Roundup considered a herbicide?
Yes, Roundup herbicide is one of the world’s most widely used herbicides. The term ‘herbicide’ refers to any product designed to kill or control unwanted plants, and Roundup’s active ingredient is glyphosate, a broad-spectrum systemic herbicide.
What does roundup glyphosate mean?
Roundup glyphosate refers to Roundup-branded weed control products that contain glyphosate as their active ingredient. Glyphosate is a systemic herbicide that works by being absorbed through plant leaves and transported to the roots, killing the entire plant. Many Roundup products use glyphosate formulations for effective, long-lasting weed control.
What sizes of Roundup weed killer are available?
Our roundup weed killer collection includes multiple sizes to suit different needs: 280ml concentrate, 1L ready-to-use sprays, 1.2L bottles (including bonus packs with 20% extra free), 3L trigger sprays, and 5L pump-action containers. We also stock refill bottles and multi-pack tube options for paths and gravel.
Can I use Roundup products on paths and gravel?
Absolutely! We stock specialist roundup path weedkiller products specifically formulated for hard surfaces. Products like Roundup Path Optima and Weedol Pathclear are designed to kill existing weeds on paths, patios, and gravel areas while preventing new weed growth for up to 3 months.
How quickly does Roundup work?
Results vary by product. Our fastest-acting formulas like Roundup Speed Ultra show visible results in just 3-6 hours. Roundup Fast Action products typically deliver results within 12 hours, while standard formulas like Total Optima show effects within 1-3 days. Complete weed death usually occurs within 1-2 weeks.
When can I replant after using Roundup?
Most Roundup products are safe for replanting after just 3 days, as the active ingredient breaks down quickly in soil. However, for path-specific products with residual action, wait times may be longer. Always check the specific product label for detailed replanting guidelines.
Is Roundup safe for pets and children?
When used as directed, weed killer roundup products are safe once dried. Keep children and pets away from treated areas until the spray has completely dried, typically 2-4 hours. Store all herbicides securely out of reach of children and pets, and always follow label instructions carefully.
What’s the difference between ready-to-use and concentrate?
Ready-to-use (RTU) products come pre-mixed in spray bottles, requiring no preparation. They’re convenient for immediate use and smaller applications. Concentrates require mixing with water but offer better value for money and are ideal for larger areas or regular users. A small bottle of concentrate can make many liters of ready-to-use solution.
Do you offer free delivery?
Yes! We offer free standard UK delivery on all orders over £50. Orders placed before 2pm on working days are dispatched the same day. We also provide tracked delivery options for your convenience, and you can follow your order’s progress online.
