Powerful, effective and no‑nonsense weed control that really works
I’ve tried quite a few weed killers over the years, especially in the garden where weeds always seem to creep back — but Rootblast Super Strength Concentrated Total Weed Killer has impressed me more than most. It’s strong, effective, and really seems to deliver on its promise of killing weeds right down to the roots. I first used it last spring, on a patch of overgrown ground that was full of stubborn weeds, dandelions, and brambles. I sprayed carefully as directed and waited. Within a week, most of the weeds had blackened and wilted, and within two weeks the overall area was clear — including deep-rooted weeds that previous weaker killers had only managed to slow down. Because the formula is so concentrated, a little goes a long way. The 500 ml bottle lasted longer than I expected and covered a good-sized area. That’s a big plus if you have a larger garden or multiple problem spots, because you don’t need to keep buying more for every small patch. I was also impressed by how straightforward it was to use. As long as you follow the instructions — spraying on a calm, dry day and avoiding delicate plants nearby — it does the job cleanly. I didn’t have to reapply multiple times, which saves time and effort. After treatment, the ground stayed largely clear; new weeds were much slower to appear than usual, which was a nice bonus. In short, Rootblast Super Strength offers a reliable and effective solution for garden upkeep. If you’re tired of weeds coming back a week after treatment, this product is one that actually makes a difference.

Takes time to work.
I'm not a gardener and since being unable to find anyone to take care of the garden, I have resorted to weedkiller to get rid of the weeds. Over the years I've mostly brought the less harmful ones. Although they get rid of the weeds, they soon grow back again. So I looked for a more stronger solution. Which is this stuff. It doesn't have measurements on the lid so I had to use an old plastic cup and weighing scales to ensure I had the correct dose. It needs 24mls per litre of water. It is on the bottle but isn't very clear and the information is not in the description. As I understand it, this is the one if you need rid of weeds permanently. I do but unfortunately it doesn't get rid of them they grow back again. I bought this about 3 months ago. I had a 5 litre sprayer, used the correct amount mixed with the water and applied. Nothing happened for about 3 weeks. Then weeds started to curl up eventually they went brown and ceased to exist. Fabulous or so I thought until I've seen more weeds grow. So looks like I'll be applying more but will have to invest in something permanent.

Love this stuff
I love this stuff and have not purchased any other weed killer since. Initially I thought it wasn’t very good, after a couple of days the weeds looked the same, however day 3 and 4 the weeds withered and after a week they were completely dead. A very effective weed killer but be careful it also kills grass and other garden plants. Value was ok, the dilution makes it go a long way. Easy to use and comes with a safety cap.

Best concentrated weed killer i’ve ever used
Works really well and quickly I have found. Weeds are under control and don’t seem to have come back in the majority of my front yard. Coming in concentrated form i’ve found that it lasts a long time. I think this is a great weedkiller for the price and I will definitely buy it again next year.

Not so much a blast, more of a mild irritation
Bought this for my drive and the path around the small garden. It's worked OK on grass and some of the weeds but a lot of the broader leafed weeds are just looking a bit tired after 2 weeks. I made it slightly stronger than recommended as it's not easy measuring out 24ml

Killed ivy.
I’ve used it to kill ivy which had taken over one side of my garden. It takes time to work and I applied a couple of applications but it worked over the winter months. The ivy hasn’t returned. Would use again.

Read the instructions
I wasn't sure if this would work I've tried numerous other weed killers. I'm starting to struggle with weeding so thought I'd try this out. No 1 read & follow the instructions it does state will take effect 3-4weeks & as you can see it has taken that long. I used all of the bottle in its correct dosages to do my double drive, the patio & perimeteredge, I have a large garden. I'd say if you was doing a smaller area you could possibly get 3 or 4 usrs out of it. I knew they wouldn't vanish but I thought with my weeding tool it would make it easier to remove. The 2nd to last picture you see of my flower pots the slabs look good but that little strip took me an hour with the use of a shovel, weed stick & a strimmer as the roots are still stuck firm. Dont get me wrong it is a good price & it does kill more than any other supermarket weed killer but you won't kill the root & I think in a couple of weeks they will of grown back.unless I take up all my drive way & put new weed barrier sheets down I'm constantly going to have weeds. I'm now currently waiting the arrival of a burner but that's because I'm after a quicker execution as I cannot bend & stand for long periods. I hope you find this review helpful
