We bought a house where the garden was overrun with weeds, particularly 6ft plus brambles amongst everything else. Decided to give this a go. Now i will confess we did cake it in the stuff, really made sure it was in there. First week we thought it had not done anything and so tried again. Second week it all starts turning, now 4 weeks on its 97% dead out there. ABSOLUTELY shocked and very impressed. This is not a super quick job but you can see that its killed the weeds from within just by how its all died out there. Even the brambles are giving up its amazing.. very impressed and would use again!
