Anyone suggest good sprayable weedkiller for perennial weeds - mainly
vineweed ( at least I think its that ) which grows in borders - pulls
up easy but thin roots go down a long way ......... also thick rooted
dandelion type weeds that are hard to get at that go under walls of
house etc. Tried Weedol without much luck . Is * Roundup* any better?
Or is there something unbranded I could get better results with

Thanks for any help
