🌱 How to Care for Japanese Sedge to Prevent Mealybugs?

💧 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.

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.
