Narrow-leaved sphagnum moss thrives in acidic, nutrient-poor, waterlogged conditions such as those found in bogs or peat gardens. It is widely used in horticulture as a moisture-retaining growing medium for carnivorous plants and orchids. Keep it consistently wet with rainwater or distilled water, as tap water minerals can harm it.
