Why knotweed spreads in Norfolk
The Wensum and Yare move rhizome fragments across Norfolk, and the county's light, free-draining soils let rhizome travel further from the parent crown than the national average. Postwar estates north of Norwich see repeated garden-to-garden encroachment along shared boundaries.
Main local pressure: Broads waterways, light soils and shared estate boundaries.
