Japanese Knotweed spread
A serious theat and a house buyers or property investors nightmare.Five years ago the Environmental Agency launched an app called Plant Tracker to map the spread of all invasive weeds.
According to my gardening mag. last month it hit a milestone, with more than 20,000 people having downloaded it, and 6,000 Japanese Knotweed trouble-spots highlighted in the UK.
High concentrations of this dreaded weed have been reported in South Wales, London, Manchester, Leeds, Sheffield, Glasgow, Edinburgh, Newcastle on Tyne, Birmingham and the southern tip of Cornwall.
Now, web-cam users can examine areas street-by-street, and see where knotweed has been reported in their neighbourhoods.
This weed can breach brick walls, come up through tarmac, damage foundations, and even get in to homes.
Mortgage lenders can refuse to approve a loan on a property, and house buyers will often pull out if a survey detects the presence of knotweed - even it it is in nearby countryside.
Japanese Knotweed was introduced to the UK by the Victorians as an ornamental plant. It was even used to stabilize embankments of canals and railways.

HiWe have Himalayan Balsam on the river banks of our fishing clubs.
We strim it and burn it every close season, from March to June.
It is not that difficult to get rid of.

Japanese Knotweed is a real pain, it took years to get it under control around a pool we took over.
We chopped it down and then kept burning it with a large paraffin flame gun every week.
It eventually worked.

I wonder if it's in a canal it'll stay there or clamber out Triffid like and invade the nearby gardens.
