Japanese knotweed (Fallopia japonica) is an invasive weed that spreads rapidly. In winter the plant dies back to ground level but by early summer the bamboo-like stems emerge from rhizomes (rootstalks) deep underground to shoot to over 7ft, easily suppressing all other plant growth.
Japanese knotweed can sprout from very small sections of rhizomes, so digging out or around the immediate area will potentially cause the weed to spread.
Under the provisions made within Schedule 9 of the Wildlife and Countryside Act 1981, it is an offence to cause Japanese knotweed to grow in the wild.
