Roundup Ultra, Tough Weedkiller, Concentrate Liquid, 500 ml

Great weedkiller for a wide ranging growth

Works fine zapped everything

Very effective but you need to mix a little on the stronger side and it takes months, not weeks, to fully work. In my case it solved what I needed it to do, which was killing off rhizome based weeds in our beds that manual pulling and turning had proliferated. It's worked to get it under control, so I can manually weed again going forwards. You need to be very patient but it does work.

I bought this product to kill ivy, bamboo & honeysuckle. Previously I have used "SBK Brushwood Killer" to do this, but after some initial success, it failed to do the job & all targets made a full recovery. In particular, there was no effect on the bamboo. With this product I followed the simple instructions under the label to make a full strength "rhododendron" mix & gave my three victims a liberal spraying. Then I waited. And waited. And waited. Two weeks after spraying, the only visible effect on any of my targets was a slight browning on some of the leaves. I made a mental note to leave a scathing review here, on my purchase of yet another useless product. However, by the third week the health of all of my victims had began to deteriorate rapidly. The leaves were now nearly all brown & thereafter the health of my three targets continued to spiral downwards. Job done, with just a single application. Highly recommended!

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

Best weed killer

Expensive for for wot it is didn't kill weeds

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.
