My normal weed killer, does exactly what it says it does and this time Amazon had the best price around and it was delivered to my door. What more can you ask.
Great product only use this product when the sun is out and hot,and only spray wear the weed is not the around the weed,the product has no smell.
Used this before and it’s does work fast, no issues fast delivery, I do empty into a large sprayer as I have a large path but it’s fine to use the sprayer that it comes with. Would recommend .
This is my third purchase. And finally, I have a sprayer that works! Weed killer is pretty efficient. I have done it twice And now keep on top of it every few weeks, so nothing grows back in the meantime Easy to apply And works within a few days
I have always had a problem with a weed called Horse tail, or Mares tail. Over a number of years I tried many many treatments- both enviro-friendly & not so friendly.
I think that this stuff had really done the job this time!! Only time will tell, I’m excited to see if it appears again next yea
It took two coats over four days to kill bramble, dandelion and other popular weeds.
Even killed the weed in my drive, there no sign of them after three weeks, amazing.
The spray system is also easy to use and I have purchased a refill, I thought the refill would have slightly cheaper but never the less it is a good product.
Nothing wrong with this product, but I could not remove the lid and pump assembly from the sprayer in order to refill it, it was completely gummed up. Therefore, check you can remove the lid etc. from your sprayer before buying a refill. In the end I bought another sprayer and kept loosening the lid, then was able to remove the lid at refill time.
Great built in pump for easy use and portability.
Worked on brick paving, concrete paths, cobble and tarmac’s drives, after a few days the weeds are purged and gardens and drives look in far better conditio
This year because of the strange weather, the weeds really took a hold on our shingle driveway. I could see it turning greener by the day. We tried this and that and it didn’t make a difference, the weeds just kept growing. Then I bought Roundup which is a bit expensive but there again IT WORKED. We used it 2-3 times during the growing months and it managed to keep the driveway clear.
There’s no doubt that Roundup weedkiller does exactly what it proports to. Indeed, I have used it to great effect on the likes of nettles, ivy and even bamboo – although repeat doses maybe required. Highly recommended.
Certainly killed the weeds, though how long they will stay dead is to early to comment. Be very careful though not to get it close to grass or flowers etc as the liquid will spread and kill any vegetation it touches. Watch out for drips too. I hope the periphery my lawn recovers next year! My mistake.
I have expensive Old York Flag Stones as half of my court yard garden… which is very large. Approx twice a year the weeds spring up between them. As i get older, i sometimes find it harder to de-weed the gaps and i find that instead of always, just pulling the weeds, i now need to do as much as i can and then use this product to finish it off. I have just done this for the Autumn and the garden looks great, with no sign of re-growth!
Does exactly what it is supposed to do.
sadly mine arrived with the pump handle broken in half – I managed a glued fix but the packaging could do with being more sturdy for the weight of the product – which makes it expensive for what it is.
This is an excellent and easy to use weed killer where digging would disrupt other plants. Also used early enough it will prevent weeds growing to excess to the point where major digging is necessary
Effect on weeds thought is was bad when I used this for the first time it rained within a hour of useing three weeks went by and the weeds where all dieing round killed them. Quality Damage done.
Brambles; my garden looked like a cross between the overgrown castle in ‘sleeping beauty’ and the island in ‘Jurassic Park’ but that didn’t stop this murder-water from turning green to brown.
We have a garden back thanks to this stuff
Very effective on clearing weeds as it kills down to the root. I found that one application was all that was needed.
There was no staining on or around fencing or slabs when used and was easy to use with a garden sprayer.
Have used this product for some years to clear weeds on drives and paths. I think it is the most effective one about. Saves having to mess about with trowels and forks. You need spray equipment to use as it is just supplied as liquid. Needs a few hours of dry weather and preferably some sunshine after application to be really effective.
Ever since my first purchase of Roundup, many years ago I have always used Roundup, as it is fast acting, usually within 2 to 3 days. I have since moved to a new property and the garden was overgrown with weeds, nettles and brambles the weeds were visibly dying in 24 hours the nettles and brambles took longer. It was a big job so I poured the refill bottle into my own sprayer because I find the nozzle on the conventional sprayer to have issues.
This refill round up works out cheaper for me. I have claimed some waste ground to turn it into a wildlife corridor as people cannot get behind us as it is well secure and since cleaning out the burn Otters are using it for a short cut to the river. I use the round up on the over grown banks makes it easier to cut with the strimmer. Always recommend Round Up good value for money 5L Refill, will continue to buy from the seller as it stays at this price beats everyone else prices.
I had a number of weeds on the driveway.
I applied 3 doses of this over a week and by the end of the second week the weeds are dead.
I’d hoped it would work more quickly with a single dose… I’ll try it on some others and see how it compares
update: I’ve found this to be far more effective on dry (and especially sunny) days, in which case a single squirt seems to take down small weeds within 24-48 hours
I bought this to kill weeds on my driveway and stoned area, one spray and the weeds were dead and brown within a few days.
I used the refill to top up an existing pump and spray bottle, taking off the lid was a nightmare (I thought I was going to snap something), and I question how much plastic is being saved with this refill bottle.
