Roundup Tough Weedkiller, Concenrate, Makes up to 100 Litres, 1 Litre

Dangerous for us but works like a dream. Would buy more any day

Have used this product for a number of years now. It certainly kills the weeks. Be respectful of the suggested amount to use. Don’t get it on any plants, grass etc you don’t want to kill !! Can take up to a week to act so be patient.

Weeds are everywhere and they grow like... weeds. I'd been using the smaller bottles with the spray head and I can rinse through one of them in about 5mins. Coverage wise the small ones might do the front drive and back patio once. So I upgraded to the concentrated stuff. Better value if still brutally expensive. Works really well and also allows you to go nuclear on hard to kill plants by increasing the concentration. The neighbour's ivy has been invading my garden - no more, it's toast! Standard strength barely dented it but by brewing up a super strength batch I torched it - job done.

I have a lot of stony paths and areas and find Roundup Super Concentrate the best at killing and preventing grasses, weeds and brambles from taking over. I use it in the Spring to stop any growth and occasionally later in the year. It is extremely effective and much better than cheaper alternatives. It is more expensive than other products, which have to be used more often.

Does the intended job.

Seemed to take effect a bit more slowly than some weedkillers I've used, but is very effective - completely cleared our drive and so far (3 weeks) no signs of regrowth

I had to treat weeds twice. First application at recommened strength had no effect at all. I repeated after 10 days.

Most EFFECTIVE long lasting weed killer available to the public. Deadly to all plants so use carefully and because it is expensive, sparingly.
