:cool: Hi,
i have just recently had some knotweed eradicated from my garden, by a company called IVM, they have a special residential department who deals with the smaller jobs in gardens. It didin't cost me that much and i got a guarantee, to make it easier for me they also spread the payments over a year. I think their website is www.knotweed-uk.com. Good Luck!

Whypay out when it is perfectly easy to eradicate yourself.

Wait until August, cut down to about 4 inches, apply a very strong dose of glysophate into the hollow stem using a syringe (from which it is drawn down into the roots). treat any marginal re-growth next spring by painting normal glysophate on the leaves.

Cost about a tenner to clear a large area.

Hi, I had a firm called IVN treat my Japanese knotweed. They have a residential department for smaller jobs like mine. It cost me an arm and a leg, but they let me pay by easy instalments. Then the Credit Crunch hit and I couldn't keep up the payments, so they took the other arm & leg in lieu. I'm typing this with my nose and life's tough, but at least I'm free of Japanese knotweed and I still know how to capitalise.

Or was capitalise what they were trying to do here....?

Have any of last year's posters had any luck with JK eradication? I have about half an acre of the evil stuff (so a few drops of herbicide down each stem is not really an option). The land it is on is bordered by a stream, so - unless anyone tells me otherwise - herbicide such as glyphosphate is not really an option?

Does anyone know: if I get livestock on the land to eat the stuff (I know this will only get rid of surface stuff and not eliminate it - which is what I really want to do because I want to grow veg on the site), will this make the spread of the JK worse (by moving it to non-infected parts of the land by disturbing it or by the animals' droppings)?

The Environment Agency has a booklet on it here that may help - http://www.environment-agency.gov.uk/static/documents/Leisure/japnkot_1_a_1463028.pdf

Hi I have a very small amount of knotweed on my land, as have my neighbours. This arrived a couple of years after a fence was replaced which ran near an existing patch of JK nearby along a boundary to our land and beyond. A couple of other patches also developed along the same boundary fence at the same time. It seems that in the process of digging in the different locations, the contractors spread small pieces of JK from one location to another. It is reported that a piece less than 5mm is sufficient to form a new plant and I am suspicious that urban patches I have seen are spread by tractors/mowing equipment.

We have tackled all the locations over the last two and a half years using the method in my previous post. The dense forest in the original location comprises about 12-15 stems this year. I have one stem on my land. This seems to be a better outcome than I have seen elsewhere.

We will hand paint these with glysophate now they are photosynethising.

If you land is other wise clear, the stem injection is not particulalry arduous. The National Trust have used it to clear entire valleys in the South West and Lake District. You require loppers and a syringe and a few funeral pyres on Bonfire Night. It ensures minimal damage to surrounding vegatation and the original patch tranformed from a desert to a flourishing hillside in less than a year, with no real damage from later treatment.

You really do have to hit it hard in the year after the first treatment, although the re-growth is minimal.

Napalm it from Orbit, its the only way to be sure you will get it all !

ok, serious head back on . You could try Sodium Chlorate.
Its cheap and cheerful and effective to an extent but dont get it near anything you want to keep.

Sodium Chlorate kills off most weeds although I don't have any experience of JK - thank goodness!

Just a reminder Sodium Chlorate is highly inflamable even in solution:eek:
