Why Himalayan balsam is a problem in Alnwick
On Alnwick properties, Himalayan balsam fires seed up to seven metres, smothers native bankside vegetation and leaves bare soil that erodes into watercourses each winter. Alnwick sits in Northumberland, where river corridors, railway embankments and post-industrial ground give invasive weeds like Japanese knotweed plenty of disturbed soil to colonise. Older housing with long gardens and vacant plots around the town see regular outbreaks, and infestations commonly spread along watercourses and disused rail lines into neighbouring streets.
