The Roundup Super Concentrate Tree Stump and Root Killer is designed for effectively eliminating stubborn, unwanted plants including tree stumps, brambles, nettles, and even Japanese Knotweed. Its key benefit is a powerful, deep-root killing action that fully degrades in soil, allowing for replanting; however, it requires precise application to ensure efficacy and avoid unintended damage to desired vegetation.
Super Concentrated Formula: Delivers powerful active ingredients in a potent form, ensuring effective destruction of tough plants.
Deep Root System Kill: Specifically formulated to be absorbed by plants and translocated to the roots, killing the entire plant from the inside out.
Targets Tough Weeds: Highly effective against a wide range of resilient unwanted plants, including tree stumps, brambles, nettles, and notoriously difficult Japanese Knotweed.
High Yield Treatment: A single 250ml bottle has the capacity to treat and eliminate up to sixteen individual tree stumps, offering significant value.
Environmentally Friendly Degradation: The formula fully degrades upon contact with soil, preventing harmful residues from accumulating in the environment.
Safe for Replanting: Because it degrades in soil, treated areas can be safely replanted with new vegetation once the unwanted plant has died off.
Extremely effective on stubborn and deep-rooted plants.
Biodegradable formula ensures no harmful soil residue and allows replanting.
Economical; one bottle can treat a large number of stumps (up to 16).
Versatile in application, targeting various difficult unwanted plants.
Specifically designed for complete root kill, preventing regrowth.
Requires careful and precise application to avoid harming desirable plants.
Results are not immediate; it takes time for the product to translocate and kill roots.
Requires dilution and preparation, not a ready-to-use solution.
May require protective equipment during handling and application.
Not suitable for broadcast application over large areas of mixed vegetation.

The Roundup Super Concentrate Tree Stump and Root Killer excels in tackling some of the most persistent unwanted plants in your garden. Its strength lies in its super concentrated formula, which means a little goes a long way, capable of eliminating up to sixteen tree stumps from a single 250ml bottle.
This product is a systemic weed killer. Once applied to the leaves or freshly cut surfaces of a stump, the active ingredient is absorbed by the plant and translocated (moved) throughout its vascular system, all the way down to the root tips. This ensures a complete kill of the entire plant, preventing regrowth from the roots.
Tree Stumps: For newly cut tree stumps, apply the diluted solution liberally to the cut surface, especially to the outer ring of sapwood, as soon as possible after felling. This allows the product to be readily absorbed by the active cambium layer and transported to the roots.
Woody Weeds & Brambles: Apply to the foliage of established brambles and other woody weeds. Ensure good coverage without run-off. The plant will absorb the concentrate through its leaves.
Nettles & Japanese Knotweed: For these persistent weeds, a thorough foliar application is effective. For Japanese Knotweed, specific application methods (e.g., stem injection or repeated foliar sprays) are often recommended, always consult detailed instructions for optimal results.
The key to successful performance is accurate mixing and thorough application. Because it's a root killer, visible effects won't be immediate. Expect to see wilting and yellowing over several days to weeks, leading to the complete death of the plant.
Read the Label: Always begin by thoroughly reading the product label for specific dilution rates, application instructions, and safety precautions. Dilution rates vary based on the target plant and application method.
Dilution: As a super concentrate, this product must be diluted with water before use. Use a clean sprayer or applicator. For stump treatment, a higher concentration is typically used. For foliar applications, a lower concentration is common. Refer to the label for precise ratios.
Safety Gear: Wear appropriate personal protective equipment (PPE), including gloves, eye protection, and suitable clothing, to prevent skin and eye contact.
Compatible Plants: Designed for use on a wide range of unwanted woody and herbaceous plants, including tree stumps, roots, brambles, nettles, and Japanese Knotweed.
Incompatibility: This product is a total herbicide. Do not apply to or near desirable plants, lawns, or areas where you intend to grow desired plants immediately. Overspray or drift can cause severe damage or death to non-target vegetation.
Storage: Store the concentrate in its original container, tightly closed, in a cool, dry, well-ventilated area, away from direct sunlight and frost. Keep out of reach of children and pets.
Disposal: Dispose of unused product and empty containers according to local regulations. Do not contaminate water sources when cleaning equipment or disposing of waste.
Equipment Care: Thoroughly rinse application equipment with water after use. Do not use the same equipment for applying other garden treatments (e.g., fertilizers, fungicides) without proper, exhaustive cleaning.
