Japanese Knot Weed (Merged)

If the Council told you not to use it, I wouldn't.

So you folks all think sodium chlorate is ok to use near a drainage system ?- don't want to end up poisoning a river or anything.

Check the labelling, its been a while since i used it but i recall it being bio degradable
so it definately breaks down in the soil with time (via micro-organisms) not sure if the same it true with water. Our local council used to use big bags of the stuff all over the place a few years back - that may not be any recommendation though !

We had japanese knot weed in our old garden what a nightmare that stuff it! ... we bought some cheap powder weedkiller white stuff not sure what it was called but aparently it was ment to be evil stuff! we carefully chopped the tops off down to ground level bashed the stalks a bit and then injected the weedkiller down the tops and into the shaft ...... didnt seem to work tho!! ... Hope you find somthing to sort it out!

I had it in my previous garden and the only thing that worked was to keep on pulling it out, eventually we got all the roots out and it stopped growing.

Can't get to the roots, as it's coming up through the gaps in the paving, and I don't really want to lift the whole lot up - it's where the neighbours take their bins in and out, so I think they'd object.
I've checked the pathclear and it says not to use where it can get into drains, so looks like that's out.
Off to Poundland to buy a job lot of glyophosphate -looks like I'll have to persevere with that for now.
Cheers all for the advice. (Mr Developer is now muttering about flame throwers and trying to torch it all - I foresee my garden fence going up in flames if I can't convince him otherwise.) Wish me luck.

elsien,

We have a thread similar to this already, I'll add your query to it so all the replies are together. Posts are listed in date order so you'll need to read from the beginning to catch up

Did you know that the rate this weed is growing it will eventually take over by strangling our natural habitats e.g foxglove etc., our beautiful woodlands will disappear for ever! It is vertually impossible to get all the root up,so the best thing to do is if you see it in flower is, DEADHEAD IT SO THE SEEDS DONT SPREAD!

someone i used to know bought a jap knotweed at a car boot thinking it was unusual and pretty. She planted it in her garden with all her other lovely plants and 6 months later that's all there was in her garden. She hacked it back, burned it, dug it up, paid a landscape gardener to kill it by injecting nasty things into it and nothing. She tidied it up to sell her house and has left it behind, that's pretty much the only way.

it is the roots that spread, not the seeds.

Once you identify it in your garden can i suggest you seek a specialist to treat it. It only takes one finger nail size of the weed to establish itelf and then grow at an alarming rate! Plus you are not guaranteed to remove it all in a DIY job. There is no cheap and easy way though to rid this pest.

If JK is located within your land, you are responsible for preventing the spread of it. If a neighbour neglects the obligation, I am sure you can progress with legal matters (if you see fit)
