A scrambling annual of cultivated land, hedges, river banks, waysides, soil heaps and waste places, also growing in more natural habitats such as scree slopes and shingle. It inhabits both tall-herb and ruderal communities, thriving on highly fertile soil. Seed is dispersed by mammals. 0-440 m (Clun Forest, Salop).
The overall distribution of G. aparine is stable. It is a highly successful and abundant weed, especially in arable crops, and is probably increasing in abundance despite the use of species-specific agricultural herbicides.
European Temperate element, but widely naturalised so distribution is now Circumpolar Temperate.
