Why Himalayan balsam is a problem in Thornbury
On Thornbury properties, Himalayan balsam fires seed up to seven metres, smothers native bankside vegetation and leaves bare soil that erodes into watercourses each winter. Thornbury's rural setting near the Severn Vale's disturbed orchard land and old quarry sites has allowed knotweed to spread along hedgerows and the disused railway line towards Yate.
