Why Himalayan balsam is a problem in Winchester
On Winchester properties, Himalayan balsam fires seed up to seven metres, smothers native bankside vegetation and leaves bare soil that erodes into watercourses each winter. Around Winchester the River Itchen's water meadows and the old Didcot, Newbury and Southampton railway cuttings have allowed knotweed to establish, spreading further via disturbed ground near St Cross and the historic water mills along the valley.
