Knotweed control treatment in a 3-pack kit for the eradication of Japanese knotweed, hogweed and other invasive plants. Powerful herbicides for use by professionals only. Japanese Knotweed is a hardy and invasive bamboo-like plant that can cause costly problems on construction sites and in residential gardens. Effective knotweed control requires high strength herbicidal spray treatments and excavation of the extensive root system. Due to the hardy nature of Japanese knotweed, hogweed and other invasive plants, it can often take several rounds of herbicidal treatment to fully control and erradicate the knotweeds outbreak. Roundup Pro-Biactive herbicide concentrate contains Glyphosate and is sold for qualified professional use only. Users must wear suitable clothing (coveralls), rubber boots and suitable protective gloves (not provided). Dilute at the rate of 1 part herbicide to 40 parts of water for treatment of most prenial weeds and 1 to 40 for treatment of hardy invasive plants like Japanese Knotweed and 1:20 for Ivy Here is a link that might be useful: A PRODUCT

Hi - we managed to get rid of knotweed completely - will tell you how I did it. I'm here because of a BBC article and got me remembering and thinking. I don't understand why everyone says this is so difficult to get rid of it seemed really easy to me anyway. 4 years ago we bought a flat - it had knotweed noted on the survey, it was pretty big area of huge tall weeds, but we haggled the price and bought for cash. Told we wouldn't get a mortgage because of the knotweed. Neighbours told us it was a nightmare they had battled for years and told us all the stories of council officials coming out to look at it and trying to apply for grant funding etc etc to get it dug out with JCB's and burned. Anyway, we decided ourselves to get an estimate from a professional company - priced in the £000's. I did some reading and research about the plant and controlling it. Went to b and q and bought a large quantity of the strongest glyphosate I could find, it said it could treat like 500m/sq. this patch was maybe 20 metres by 5 metres - pretty big for me anyway. It was supposed to be pretty diluted but I only used about 10% water maybe. I also bought a £15 manual spray pump and some gloves and some sponges. I went with some ladders on a Saturday morning in August, it was about 15 degrees C, cloud cover and dry. i coated every single leaf I could with the stuff - several times during the day and again after it dried off or was absorbed. I then found all the thickest stems and bunches and cut them down about halfway, and poured the stuff into the stems - filled right to the top. Then topped them off later that evening - and used the last of the strong spray solution I had made for another final spray coating. Over the next few weeks they starting visibly dying. The winter came and went and by July the following year everything was completely dead. I took plenty of before, during and after photos which I still have. That was 4 years ago I did that and not one single sign of it has returned. It cost me like £80 of materials and maybe 12 hours of my time. I knew nothing whatsoever about Japanese knotweed or plants and gardening and still don't. I was later told that national rail and the local council had actually sent 'a man' every season for 'several years' previous to our buying the place to 'spray the plants' to try and get rid of them. With little success apparently. What I find totally and utterly bizarre is that someone like me, completely clueless about horticulture and plants, was able to completely kill - permanently - a pretty substantial bank of this stuff in like 1 day, with stuff bought from the local hardware shop - and yet the Internet is full of stories and news reports of people spending fortunes and despairing in heartache over it. Was I lucky somehow? Genuinely I've always been curious about this and would welcome input from those more experienced.

I have 2 huge patches I have recently begun work on...we just bought our house last fall...and had no idea what we were getting ourselves into with the "cool looking bamboo" in the yard. Well...since then I have learned a LOT quickly! But it seems the bottom line is eveyone has varied opinions and there is a lot of experimenting going on. After reading your plan my thoughts are - that it sounds great but I would leave a few weeks time for the poison to take effect - I noticed it took several weeks for it to show any signs of damamge...(i also use glyphosate 50%) but ALSO - it is best to treat it with glyphosate in August or September when the plant is bulding it's reserves for the winter - it is taking nutrients down to it's roots...so it will take the poisen down into its roots most succesfully at that time...and its the roots you need to kill to eradicate it. I did one treatment in early spring - and it still came back but alot shorter and definately damaged...so I plan to do one more treatment in aug/sept. GOOD LUCK!!!

You say 'fast growing' but one idea is to gather seed from the locality naxt Autumn and grow some of your own trees. I did this to fill in an area where I had had Japanese Knotweed eradicated. The willows and poplar will grow from lengths stuck in the gound. Understorey wild flowers are also quite easy from seed. Primroses and cowslips for example are very easy. Personally I wouldn't introduce bramble to a small woodland. It will probably arrive by itself anyway. Can I recommend you join the Small Woods Association? And the Forestry Commission has a lot of useful information - maybe even some grants available. Good luck with your project. Here is a link that might be useful: Small Woods Association.
