Roundup Tree Stump Weedkiller, Super Concentrate 250 ml — practical stump and deep-rooted weed control
Reviews
Product description
What it is
Roundup Tree Stump Weedkiller is a liquid concentrate designed to tackle stumps, trees and a range of deep-rooted weeds. Packaged as a 250 ml concentrate, it’s marketed to degrade in the soil by micro organisms and to leave no harmful residue, which can be appealing for garden clearances where you want to minimise leftover chemicals.
What it does

On the page, the product claims it can kill stumps, trees, brambles, nettles and other deep-rooted woody weeds, including Japanese Knotweed. The claim that it can kill up to 16 tree stumps gives a sense of its potential coverage, although exact results will depend on plant size and site conditions. The idea of soil degradation by micro organisms suggests the product is designed to break down over time rather than leaving persistent residues.
How to use it
If you’re considering this product, you’ll want to follow the label directions precisely. Concentrates typically require dilution and careful application to target plants, with attention to root systems and proximity to desirable vegetation. It’s not a one-step solution for every situation, and outcomes can vary based on the species being treated and the age of the stump.



What to like
The emphasis on versatility—stumps, brambles and other deep-rooted weeds—addresses a common gardening challenge in one product. The claim of no harmful residue after degradation can be reassuring for garden use, and the concentration format may offer cost-effectiveness over bulk products. The potential to address stubborn knotweed signals practical value in settings where such invasives are an issue.
Limitations and caveats

It’s important to recognise that outcomes are described as claims on the product page and may depend on site conditions and plant size. The number of stumps killed (up to 16) is a rough guide rather than a guaranteed count. As with any herbicide, safety precautions, proper storage and application guidance are essential, and results may vary if used inappropriately or on plants not listed on the label.
Who it’s for
This product could suit homeowners or land managers dealing with stumps and deep-rooted weeds in gardens, allotments or around outbuildings where a targeted, potentially residue-minimising approach is preferred over mechanical removal. It may appeal if you want to reduce residual soil impact while tackling woody invasives.



Who it isn’t for
If you need immediate, large-scale clearance or if you’re dealing with non-woody annual weeds, this concentrate might not be the fastest route. For very small, easily managed invasions, a lighter approach or manual removal could be simpler. If knotweed or similar chemistries are a concern, ensure compatibility with your site and nearby plants first.
When it makes sense to buy

Consider it when you face multiple stumps or deep-rooted woody weeds and are looking for a single product capable of addressing several targets. If you prioritise a product with a degradation claim and a focus on minimal residue, this formulation could be worthwhile.
What to check before buying
Verify that you have stumps or weeds listed as targets and that the size or density of the infestation aligns with your expectations. Examine label instructions for dilution ratios, application methods and safety guidelines. Consider whether you have the right setup to apply a liquid concentrate safely and effectively.



Practical use case
Imagine clearing a small woodland edge or garden boundary where several stumps and brambles persist after a clearing project. A concentrated solution can be prepared and applied to the stumps and woody weeds, aiming to reduce regrowth and limit future intrusion. The approach should be paired with subsequent monitoring to confirm effectiveness and manage any re-emergence from existing root systems.
FAQ
- How many stumps can I treat with 250 ml? The product states it can kill up to 16 tree stumps, but actual results may vary depending on stump size and species.
- Is there a risk of harming nearby plants? As with any weedkiller, follow label directions and take care to avoid drift onto desirable vegetation. Residue-free claims refer to soil degradation but do not imply universal safety for all plants.
- Can it handle knotweed effectively? The listing mentions Knotweed as one of the targets, but effectiveness will depend on site conditions and proper application per the label.
Is it worth it?
Worth considering if you’re tackling multiple stumps or deep-rooted weeds and want a concentrated solution with a stated residue-friendly profile. It may not be the best choice for very small jobs or for users who prefer a non-chemical approach. If you prioritise rapid, large-area clearance, consult the label guidelines and assess whether the concentration and target species match your site.
