  • Tips & Advice

Deadfast Tree Stump & Weedkiller kills tree stumps (hard and soft wood), brambles and controls annual and perennial weeds such as
grasses, nettles, willowherb and dandelions around the garden.

For larger trees and shrubs use Deadfast Tree Stump & Weedkiller by cutting and then treating the stump. Smaller shrubs and woody weeds (such as brambles), below 1 metre in height, do not always need cutting and Deep Root TreeStump & Weedkiller can be diluted as an overspray. For other annual and perennial weeds apply as a spray application.

Total Herbicide

Deadfast Tree Stump & Weedkiller will kill most living plant tissue and roots. As such, please avoid all contact with wanted plants. After use ensure that garden sprayers and other vessels used for application are thoroughly cleaned as traces of the product left in the equipment can damage or destroy plants sprayed later.

Systemic Action

Deadfast Tree Stump & Weedkiller is carried throughout plant systems by the plant sap. After absorption through foliage or cut stump, the
ammonium salt of glyphosate is carried to the outer extremities of the plant’s root system where is begins to work. Effects should be visible within 7-14 days.

Note: Deadfast Tree Stump & Weedkiller will not cause tree stumps to degrade.


Instructions for use

Stump Application (Ready to use)

For best results stump application should be made in November to March (thus avoiding application when the tree sap is rising).
Cut off the corner of the sachet and pour evenly across the cut surface of the stump as soon as possible but not later than a week after felling. If a callous has formed, then expose some fresh wood by cutting or drilling into the stump surface before applying.

Spray Application (Dilution Required)

For spray application Deadfst Tree Stump & Weedkiller should be diluted with clean water. Pour the contents of the 100ml sachet into a garden sprayer, or similar, and dilute to make 1 litre of spray. Spray weed leaves lightly until wet, but avoid run-off of the liquid.
For best effects, apply from March to October when weeds are actively growing on a large leaf area allowing plenty of weedkiller to be absorbed.

Effects may be seen within a few days but full control can take up to 4 weeks. If it rains within 6 hours of application, then effectiveness may be reduced and re-treatment is recommended. Apply this product carefully and is confined only to visible weeds including those in the 30cm swath covering the kerb edge and road gulley – do not overspray drains.
