Why Himalayan balsam is a problem in Washington
On Washington properties, Himalayan balsam fires seed up to seven metres, smothers native bankside vegetation and leaves bare soil that erodes into watercourses each winter. Washington's former colliery workings and New Town infrastructure along the River Wear left disturbed, reclaimed land where Japanese knotweed has spread through the wetland nature reserve and old mining spoil sites nearby.
