– Rootblast | Super Strength Concentrated Total Weed Killer - Glyphosate for Effective Weed Control - Kills Weeds down to the their roots (1 x 1L), Packaging May Vary

We used it to help clear overgrown weeds and to poison a tree stump that kept sprouting ! This stuff kills everything it goes on. Very powerful and highly effective. You must be careful when using it though, protective gear, gloves, mask, something to cover your hair and foot wear that can be disposed of or washed thoroughly afterwards. Always follow the instructions ! Great stuff but respect it's potency ...

Good product seems to have done the trick with our weeds

Picked up the Rootblast concentrated weed killer, and it’s proper effective. Mix it up, spray it on, and within a week most weeds are brown and shrivelled right down to the roots. Works well on driveways, paths and garden borders. Only minor gripe is you need to be careful where you spray – it’ll kill anything it touches, so keep it away from plants you actually like. Otherwise, strong, reliable, and does exactly what it promises.

Wow! I’ve used numerous other treatments all promising the earth and nothing touched some quite substantial weeds and thistles! This was very easy to use and measure out following the instructions on the bottle. After one treatment a week later I checked the results and I couldn’t believe how effective it was! A second treatment and this bad boy kills everything, massive thistles that wouldn’t budge are now dead, and I mean totally killed everything! Nice child proof lid and doesn’t leak when in storage

Brilliant stuff killed the brambles and other weeds. Took a couple of days to see them wilt and start to go brown. Easy to use. Thanks for the gloves

This root killer weed killer works fairly well but a lot of the thicker hard stemmed with deep roots haven't died....the top branch type twigs have come off but the stems near the ground and where the twigs have fell off are all green again a couple of weeks later....they must need an enormous amount of root killer to get to the bottom of the roots and they are £40 a bottle and there is only 1l in each bottle....some of the bottles were white with the cheaper root blast super strength bottles and not the orange type liquid I originally ordered which was £40 a 1l biottle and i didn't get a refund for this cheaper version and i ordered 7 or 8 bottles all together...and only have two left....ive got a 75 foot long garden and 16feet wide and ive mixed it as 8 litres water to 1 litre root killer.....a lot of nettles are growing back and the thicker wood-type stem weeds are growing stronger again after shedding their top branch-twig like branches but it hasn't killed off the weeds after spraying a 2nd time just them and the regrowing nettles.....I'm not very happy that the largest two number of weeds haven't died mm to be fair my garden was like a jungle and loads of different insects came in the house through the open summer time windows and open back door because of the hot weather.... So ive also had to spray the house with total insect destroyer spray and fly wasp and mosquito spray for the winged insects....I had a foreign small blue fly in that bit me ferociously....it was small and looked harmless but it must have come over in someone's suitcase and it took loads of raid fly spray to kill it....I won't trust another blue English looking small fly again....so this weed killing has cost me a lot of money and time and the thicker stemmed weeds and the nettles are all continuing to grow

Works really well

Used this to stop the weeds and moss coming through on our block paving driveway. The fact that this comes in concentrate is a massive bonus as it’s a fairly large area that would get through a lot of weed killer. I mixed it to the recommended ratio in a large pressurised sprayer - made up about 4-5 litres and covered the whole area. It’s not very fast acting and took about a week to see any major effects. But after about 5 days the moss started to darken and the weeds were wilting. I gave the whole drive another pass with 4-5 litres and now -another week later - everything has pretty much died off. I’ll still need to get the jet washer out to try to rake everything out of the cracks and then resand it all at some point. But this stuff did its job fine. And knowing I’ve still got loads left in the bottle for next year definitely makes this better value for money than other options out there.
