Japanese Knotweed...... Anyone Hungry?!

That's helpful.

 

 

 

 

 

I took on a small area of knotweed 3 years ago, on the edge of a woodland. Perhaps 30m2 of it if I remember right. I cut each stem individually. Couldn't burn in situ as directly outside a school, so sealed in dumpy bags, covered them in tarp so none could fall out and put them in my yard (50m away). Spent an afternoon getting a good fire going in a drum and slowly burned the lot.

 

Then went back and filled the stems with 20% roundup biactive and sprayed the smaller plants that were too small to fill their stems. Treated again the following year in the spring then late summer (although there was chuff all left to spray). Pretty much killed right up now. Glad I didn't have more of it.

Thats exactly what I've done on the few occasions I've had to deal with it. Providing you make your cuts with secateurs to prevent fragments being created, and you're scruplous about burning everything then it does seem to work well.

Yeah, we erred on the side of mega-paranoia. It was only a small amount of it so we had the time to do it piece by piece.
