    Why groundsel is a problem in Treorchy

    On Treorchy properties, groundsel completes several generations a year, so a small patch becomes a season-long seed source across beds and gravel. Treorchy lies in the upper Rhondda Fawr, where steep terraced streets, retaining walls and reclaimed colliery land are classic ground for knotweed.
