ðą How to Care for Japanese Sedge to Prevent Slugs and Snails?
ð§ How to Water
Check the top inch of soil and water whenever it starts to feel dry. Carex oshimensis prefers evenly moist, never soggy or bone-dry, soil. Cut back watering during winter dormancy.
âïļ Lighting
Give it part shade to filtered sun for the richest foliage color; too much full, hot sun can scorch the leaf tips, while deep shade causes the plant to lose vigor and its variegation to fade.
ðŠī Ideal Soil
Use a well-draining, humus-rich, slightly acidic soil (pH 5.5-6.5). Amend heavy clay with compost to improve drainage and prevent crown and root rot.
