Control- Japanese knotweed

Hi,

Any advice for the control or eradication of japanese knot weed would be appreciated.  I have a garden to clear and this weed is present.  The weed appears to be quite small at this stage. 

 

If I dig it out is there a likelyhood it will regrow?  Are there certain places or methods to dispose of it also?

 

Thanks

Colin

My thought was to cover the whole area start on top of it with raised beds- but as these suppliers offers their expertise- I would have their advise first.

I am not saying that it is the only option- but it is a faster one.

I have a relatively small patch of knotweed on a site i maintain for a residents association, its approx 4mtr by 1mtr in area and not dense growth, more like quite a few small clumps of upto 6 six stems in each case.

I have chopped down the existing stems to a few inches from the ground and they were put to one side to dry off for burning, any regrowth has been treated with weed killer and thus far this has been pretty effective with just a few spindly stalks coming up in the last couple of months.

Obviously if it starts to re-grow in the spring im sure it wont be so forgiving!

However, one of the residents is trying to re-mortgage and the surveyour has noted the knotweed, the residents assoc wants a statement from me to show the issue is being dealt with so the mortgage can go ahead, but im just a soletrader, i dont do commercial and have not had a request like this before and i have know idea quite what paperwork/statement would be appropriate

Any help/thoughts much appreciated

Anthony I would write a letter on headed paper showing what agreement you have with the client to sort the weed out (i.e. I have been commissioned by X to undertake treatment leading to eradication of knotweed at X location between the dates on X and X. If any further plants emerge after date X I shall be contracted to resume treatment to control any potential spread of the weed).

 

You won't need anything more formal than that, and being a sole trader doesn't make a difference. To them you are the professional as indeed you are. All they need is a statement from someone to give them peace of mind that the weed is not going to over run the site.
