What is Japanese knotweed?
The Royal Horticultural Society explains,

Japanese knotweed (Fallopia japonica) is a weed that spreads rapidly. In winter the plant dies back to ground level but by early summer the bamboo-like stems emerge from rhizomes deep underground to shoot to over 2.1m (7ft), suppressing all other plant growth.

“Eradication requires determination as it is very hard to remove by hand or eradicate with chemicals. New legislation now covers its control”
