- Horticulturists…have I got a japenese knotweed / neighbour problem?
I was starting to clear up the abandoned corner of the garden and noticed an odd plant had sprung up next door and was coming through the fence. The main plant is about 2m high, red flecked reed like stems that zig zag. To me, it looks like knotweed but is there anything else that I could be mixing it up with? At the moment it’s a fairly isolated clump as far from the houses as can be.
It’s growing from the neighbours side. He doesn’t have clue and suggested he’ll just chop it down (again) if it’s a problem when I spoke to him a few days ago. I told him not to, look it up and we’ll chat again in a week. To be fair, he’s not had the house that long and isn’t really a gardener.
I gather it’s a bit difficult to get rid of properly. Has anyone had experience with it coming through from a neighbour? I understand it’s very much not allowed to let it spread to other people’s land. It’s already on my land and is going onto another neighbours as well (it’s a corner between 4 gardens).
At the moment I’m thinking of giving him a month (with a few friendly nudges) to start doing something sensible about it before getting into the formal route. I’m not that inclined to faff about it with due to potential impact on mortgages and stuff like that.

Looking at this website it does look like it is knotweed, they offer an identification from a picture but will no doubt then offer the eradication service as well.

Looks like JK. The way I understand the law is that it is not allowed to be spread through action (digging it up and disposing of the waste, cutting it with a strimmer and/or disposing of live growth inappropriately etc. But there is nothing in the law which prevents inaction. (by doing nothing he is doing nothing wrong.) Get spraying it, have a word with them. Injection works really well if done at the right time of year (just before it starts dying back in the late summer.) (this law thing may be a Scottish thing)Posted 1 year agocloudnineSubscriber
Looks like knotweed.. he can get into shit if it spreads onto your land..

It’s a criminal offence to actively plant it / spread its growth as it’s a red list invasive species.
It can cause serious foundation issues.
It is also a nightmare to kill and even more of a nightmare to dispose of any cuttings as they have to be buried, preferable in a liner, a min of 5m down.
If it’s not already in your garden (which the roots may well be) get a root barrier down asap and burn any soil you suspect of containing roots from the plant.
I know if a few JK disposal companies if you want to PM me I can send you their details depending where in the country you are.Posted 1 year agoHounsMember
I’m currently dealing with a single plant of JK at a relatives. What I’ve done is cut the stems at about 15cm above ground (and burnt the stuff I’ve cut off) and poured in the nastiest, strongest weed killer I could buy from a farm suppliers down the stem (they are like tubes) I’ve also totally covered the plant so it can’t get any light.
I’ve been doing this for last 7 months and yet it’s still putting out new shoots, sadly I think it’s time to get professionals in (OHH I could do with those suggestions please)Posted 1 year agoperchypantherMember
I had one plant growing up between our garden and our neighbours.
A bottle of Roundup Ultra concentrate applied , undiluted , to each leaf with a paintbrush and leaving it for a couple of weeks before cutting it back were , seemingly, enough to kill it.
That was 6 or 7 years ago and no sign of regrowthPosted 1 year agoJoeGSubscriber
Most effective time to treat is late summer:Posted 1 year ago
