Hoo boy!! That is Japanese knotweed, Polygonatum cuspidatum, the plant from hell!! Do some serious research on this..........it is extremely difficult to even control, let alone remove. This is a multi-year project.

Thank you. I wasn't completely certain that's what it was. Some Minor variations from the images I've seen. I've been fighting it with Roundup (spot treatment), and using a spade to sever (but not scatter) the rhizomes along the fence line. I've also planted some Incense Bamboo, (Phyllostachys Atrovaginata) in hopes that eventually it will out compete that demon weed.

fighting it with Roundup

===>>> applied how ... diluted or undiluted ..???

get the very expensive applicator at the link.. remove product.. fill with undiluted RU ... the beauty of it.. is that it doesnt spill if knocked over... and allows application of single drops ... no waste.. no excess use ...

do not store near the hot dogs ..and i you might be best off.. returning unused product to the properly labeled container ...

snip a spring.. apply one drop ... continue ad nauseum until you kill the root mass ... it might take years ...

i once battled an underground poison ivy vine.. for 3 years ... i eventually won ... and what i found was.. i would have to go out about every 6 weeks.. or whenever i saw a new crop of sprigs ...

this type of project really isnt a diluted spray thing .... RU is labeled as a stump killer.. undiluted.. and that is basically what you are doing ... killing a root mass
