It usually grows in wetlands. The two subspecies differ slightly in requirements, with S. c. cinerea generally restricted to basic marshland and fen habitats, while S. c. oleifolia is less demanding, occurring in both alkaline marshes and acidic bogs and streamsides. A common herbivore of Salix cinerea is Phratora vulgatissima, which prefers and is more common on female plants. Anthocoris nemorum, a natural enemy of Phratora vulgatissima, is also more common on S. cinerea.
