Roundup Ultra, Tough Weedkiller, Concentrate Liquid, 500 ml

Best weedkiller we have found to kill off garden weeds. Concentrated so economical to use. One weed we call dead man’s finger ( don’t know if that’s the real name) is a weed from prehistoric times - it even kills that - maybe not first try but persevere and it dies. Great product. Good

Very effective, within a matter of hours/days everything wilts and turns crips (if doing a total lawn destruction). The weeds to do return though on barron land, after about 10 months say.

A difficult one to review. I am NOT knowledgeable in things garden, but it seems this product sometimes seems to work and other times seems not to work.

Best weed killer

Works fine zapped everything

Expensive for for wot it is didn't kill weeds

4 stars as lacks clear instructions (and Im an ex Maths teacher so capable of calculating properly) for use on bottle [ Edit in fairness discovered the label had come off first bottle (Poor)] however 20ml in a 3 litre sprayer has worked for us BUT a larger sprayer would be a better option, worked well on a recent Himalayan Balsam invasion on a bank (a surprise worked so well) but respect should not be used near water courses. Taken 8 - 10 days for weeds to show dying back around an ex horse paddock but a clear line where i sprayed. Will repeat the task next week.
