it mite but its a very strong weed . give it a go and then do it again if its worked at all . realy your probably better to keep pulling it up .

my mum just said cut it down and wate for the new shoots and use systemic weed killer and keep repeating in the growing season .

I have some ground elder coming under the fence from next door, I find the only way is to dig it up and again, trying not leaving any bits of root. I could not treat it as its amongst plants.

According to the information on the web site it should kill ground elder, Bg. I see that one of the ingredients is diquat which I thought was banned years ago. It was the active ingredient in weedkillers that potential suicide victems drank and resuted in renal failure.

Sorry, I gave wrong information iin the second part of my response. The substance that I was thinking of was paraquat, not diquat. My involvement was in the 1970s so I blame memory for the mistake. I am surprised to see that it was not totaly banned until 2007!

A simple barrier between you and next door, like thick plastic buried in the ground, might help. A friend has a similar problem which has now spread to the lawn and the ones in the hedge are in flower. I've removed any flowers and tried, as Drc726 says, digging it up where I can and them spraying new shoots when they appear. I find Resolva quite good. Another problem is when it gets into a shrub border and into the roots of other plants.
