Japanese Knotweed

Bird Dog at Maggie’s Farm reports on the invasive plant Porcelainberry and its rampage throughout the northeast U.S. I’ve been battling an equally notorious invasive, Japanese Knotweed, since we moved in four years ago. It can grow to over 10 feet in height and is found in the eastern U.S. along with a few midwestern and western states.

I have been slowly getting rid of a big patch in my backyard through pulling, mulching (with both newspaper and shredded hardwood), and, yes, good old chemicals. Roundup seems to work well; one group in the UK, where it is illegal to grow the plant in the wild, advocates “injecting glyphosate into hollow stems immediately after cutting”.
