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

Right. I feel I need to clarify how this works - as some of the reviews expect results in hours or the next day. 🤦‍♂️. I get it, some people just aren’t that in the know with DIY, and that’s okay. So, here’s the low down: This is a “systemic” weed killer. It will kill the entire plant. It is very good at this. But, it takes time! Unlike some weed killers that promise results within days, this is designed to get a proper job done, and does not pretend to show results. If you are using another weed killer that is showing results within hours, you can bet your bottom dollar that’s by design - from the marketing department. But I assure you that weed killer may look like it’s doing a good job, until the weed returns a few weeks later because the root was untouched. You essentially just burned the leaves. This stuff interrupts the plants ability to make essential enzymes for the plants to live. That takes time. But it kills the entire plant - properly, root and all. Depending on the species, it will take between 1 to 4 weeks to fully kill. You’ll likely see wilting within a week. Now here’s the important part - this is absorbed through the leaves - do not be tempted to pull the weeds before or after application. No leaves, means no absorption, means no worky. Be patient, don’t be tempted to “help it along” by trying to manually remove the weed - you’ll hinder the process. You’ve been warned. Don’t apply when it’s going to be raining, or excessive heat (daylight sun) - it needs to absorb. Rain will wash it off. Too much direct sunlight will dry it before it has time to absorb - so apply early morning or evening, and avoid mid day sun. Then be patient. The one star reviews expecting results within hours, or the next day, simply do not understand what they have bought. Now you know. Excellent stuff for the money - you can make dozens of gallons from this bottle, so very price competitive to other premixed stuff. Get a sprayer, I got a cheap one from Screwfix, and you’ll be sorted for years.

Takes a while to work, but very good weed killer. A a tiny amount goes a long way so works out very economically. Excellent product.

A good quality weed killer . It appears to deal with most weeds ,although on occasions it seems to be a bit slow. Odd times a second application my be suitable. As with most weed killers it is expensive but using the instructed dilution rate it gives good coverage.

Okay I thought I would leave a review a few wks after use. Have used other strong strength weed killer that were just urgh. This stuff is great, the weeds have died off. What I actually got it for was the dreaded ivy that refuses to die so I used this, I did expect to see some results a few days later like the leaves starting to go brown etc but didn’t I thought I bought another dud. However 2 wks later it does seem to be working. The leaves are looking crusty and brown and starting to look like it is dying off. Hopefully this does the trick. It’s not as expensive as other ones I was using so I am surprised by the outcome. Child safety cap so prevents any leakage. Instructions are easy to do. Will definitely purchase again.

We have terrible weeds on our block paving, many with strong roots that are impossible to remove. Have tried loads of different weed killers but this is definitely the best. Like other reviewers have said you have to give it time to work. We applied it according to the instructions, using a Black and Decker pump spray bottle (also very good), and for quite a few days we saw no difference. If anything they looked healthier! We waited a couple of weeks and by then the weeds were all completely dead. Four weeks on and still no sign of them returning. Also only need the smallest amount so bottle will last for ages.

Has review's go this item is great, but it takes Time. If you are expecting it to work in hours then you will be disappointed, as suggested it will be days before you see results. One good thing is it works given time. Would recommend it all day long.

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

This is a good weedkiller. It does the job. However, its really slow. It took 10 days before the weeds on my drive showed any sign of dying away and 3 weeks before they died off completely. Nonetheless, more effective than many other weedkillers on the market.
