Can I use a glyphosate weedkiller such as Roundup on my lawn?
A. No. Glyphosate is not a selective weedkiller and does a great job killing grass as well as weeds. Instead of Roundup, use a weedkiller that is clearly labelled for use on lawns such as Verdone Extra. This contains ‘selective’ weedkillers that control the broadleaved weeds, but do not affect established grass.
