Landscape Advice Note: Problem Weeds
By Alan Cathersides
Japanese knotweed ( Fallopia japonica) is a non-native herbaceous plant. Introduced from Japan as an ornamental for large gardens it is now an invasive weed, common throughout most of the British Isles. It spreads mainly by the vegetative means of underground rhizomes. The rhizomes can spread for long distances and often penetrate quite deep below the surface.
This Landscape Advice Note explains the options available for dealing with these problem weeds on historic sites.
