How to Control Japanese Knotweed

Slow connection? Watch in lower quality

With an academic background in biology, environmental forestry and eco-physiology, Dr Paul Beckett shares his expertise in Japanese Knotweed - its life-cycle, different methods of managing it, plus the legalities of it being a `controlled waste`. In collaboration with Professor Anthony Moore of the University of Sussex and Julia Shearman, a PhD student funded by the Biotechnology and Biological Science Research Council, he is looking at new ways to inhibit the rapid growth of this invasive plant.

There's nothing wrong with the way she chooses to groom herself. Your comment on the other hand…

I hear on the grapevine a new way of tackling it. Injecting a chemical in the base of its stem. Apparently it goes right down to the roots and kills it slowly

So the answer to "How do you control Japanese knotweed" is you don't know?

I mean they listed ways to control it. Burning and destroying the rhizomes. Just the financially feasible vs effective doesn't match up yet.

Glyphosate foam has been effective but if you are against herbicides then there will be no easy control. Mechanical will be your only option. But you can eat the leaves and maybe grind the stalks and turn that into compost/burn it.
