Why knotweed spreads in Devon
Devon's steep river catchments move rhizome quickly during winter spate, and the county's long growing season extends the effective herbicide window later into autumn than most of the UK. Coastal and estuary plots need careful surveying before any dig is priced.
Main local pressure: Steep river catchments and a long southern growing season.
