    Why black medick is a problem in Derry

    On Derry properties, black medick spreading annual clover-like weed that colonises thin, dry lawns and path edges through summer. In Derry, Japanese knotweed and Himalayan balsam spread along the River Foyle and its tributaries, where floods and riverbank works carry rhizome fragments downstream. Verges and green spaces around Peace Bridge and City Walls, along with new housing on the edge of town towards Culmore and Eglinton, are where we most often find established stands.
