Paid a lot of money to do up my front garden with weed control and slate. Within 6 months or just under I had these really bad weeds and stinging weeds growing rapidly every time I went to de weed the garden. Never ending. So I purchased this, it’s amazing. As long as you use it when it’s a sunny day and no wind it is fine. Spray on weeds only if it’s sunny for a good three days because the rain will just wash it away. The weeds are dead and not comming back and these were vicious weeds. Can finally park my car next to the front garden without getting stung.
Im really pleased with this product, it had quick results too. The other roundup version of this product seemed to feed the weeds not kill them, but this wiped them out straight away. I did use it on a hot sunny day, which may have helped too. Would recommend.
This is perhaps the strongest weedkiller available to the general public and I have read it will be banned from 2024.
I’m sure if you are unable to physically get down to weed the garden yourself, this would be a great addition to your gardening kit as it does work and apparently kills the roots as well. However, if you can get out there and pull them up, you may as well save yourself some time and money and do just that.
