SBK Brushwood Killer in a 250ml Pack of soluble concentrate.
This weedkiller by Vitax is for use on tough weeds, such as brambles, thistles, nettles and docks. It is a selective weedkiller that kills broad leaved weeds not grass.
As with all weedkillers, you should read the label before use, however, in general terms SBK Brishwood Killer can be used from May to October when the soil is moist and weeds are actively growing. If using on woody weeds, use from June to August. You can also treat tree stumps in autumn and winter.
