THE COST OF IGNORING JAPANESE KNOTWEED

摘要

Japanese knotweed (Fallopia japonica) is a particularly invasive, fast growing, bamboo-like perennial plant. It spreads through its creeping root system (fibrous rhizome) which allows for its rapid spread that can grow up to three metres in height. Even a tiny amount of rhizome, as small as 10mm, can generate a new infestation reaching a depth of three metres and extending out up to seven metres from the parent plant stem.
