Vitax SBK Brushwood Tough Weedkiller 1 Litre

Kill tough weeds such as brambles, thistles, nettles, dock, and woody weeds with Vitax SBK Brushwood Tough Weedkiller 1 Litre, a soluble concentrate weedkiller that targets both the weed and its roots to prevent re-growth, without harming surrounding grass.

Ideal for tackling overgrown areas, neglected borders, fence lines, and woodland edges, SBK Brushwood Killer is applied as a foliar spray that absorbs into the plant and travels down to the roots. One 1 Litre bottle treats up to 332m², making it well suited to medium and large gardens.

This soluble concentrate is mixed with water and applied using a watering can or sprayer as directed. Apply when there is active growth, the soil is damp, and there is no risk of freezing. A maximum of two treatments per year are required, with at least six weeks between applications, and a six-week interval is also needed between application and re-planting. SBK can also be used to treat wood stumps when sap is no longer rising — for best results, apply during autumn and winter.

How to Use

• When to apply: May to October for tough weeds and hardwood saplings; June to August for woody weeds. Avoid April, May, and June when treating tree stumps (sap is rising).
• Mixing: Dilute the concentrate with water as per the product label.
• Application: Apply evenly to foliage using a watering can or sprayer when soil is moist and weeds are actively growing.
• Coverage: One 1 Litre bottle treats up to 332m².
• Re-treatment: A repeat application can be made after six weeks if required (maximum two treatments per year).
• Re-planting: Wait at least six weeks after application before re-planting treated areas.
