Hypnum mosses encompasses moisture-loving, shade-tolerant plants often found carpeting forest floors. Basic care requires consistent moisture without waterlogging, dappled sunlight to partial shade, cool to moderate temperatures, and well-draining, rich organic soil. Common challenges include slugs, snails, and overexposure to sun leading to desiccation. Seasonally, hypnum mosses requires protection from extreme temperatures, with increased humidity in summer and reduced watering in winter to mimic its natural habitat's cycles.
