The 'Korean Rock' Fern, scientifically known as Polystichum tsus-simense, is a handsome and resilient fern native to East Asia, including Korea, Japan, and China. It's known for its lush, dark green foliage and its ability to thrive in a variety of conditions, making it a popular choice for both outdoor and indoor gardeners. The fern's compact size and graceful, arching fronds add elegance to shaded garden areas, terrariums, and indoor spaces.

🌿 Botanical Name: Polystichum tsus-simense (Korean Rock Fern)

💧 Care Level: Easy to moderate. The Korean Rock Fern is adaptable and relatively easy to care for, making it suitable for beginners and experienced gardeners alike.

📏 Size: The Korean Rock Fern typically grows to about 12 to 18 inches (30 to 45 cm) in height and width, forming a neat, rounded clump.

☀️ Light: Prefers partial to full shade. The Korean Rock Fern thrives in dappled sunlight or shaded areas, making it ideal for woodland gardens or as an understory plant. Avoid direct sunlight, which can scorch its fronds.

💧 Water: Keep the soil consistently moist but not waterlogged. It's important to provide regular watering, especially during dry spells, without letting the plant sit in water.

💦 Humidity: The Korean Rock Fern benefits from moderate to high humidity levels. If grown indoors, occasional misting or a pebble tray can help increase humidity around the plant.

🌡️ Temperature: Prefers cool to moderate temperatures, ideally between 50°F to 70°F (10°C to 21°C). Protect the fern from extreme heat and cold drafts.

🌱 Soil: Plant in rich, well-draining soil with plenty of organic matter. A mixture of loam, peat, and sand or perlite can provide the right balance of drainage and moisture retention.

🌱 Fertilizing: Feed lightly with a balanced, slow-release fertilizer once at the beginning of the growing season. Over-fertilizing can harm the fern.

🔄 Pruning: Pruning is minimal. Remove any brown or damaged fronds to keep the plant looking tidy and to encourage healthy growth.

🍃 Pests and Diseases: The Korean Rock Fern is generally disease-resistant but keep an eye out for common indoor pests like aphids and spider mites. Treat any infestations promptly with appropriate measures.

Propagation: The Korean Rock Fern can be propagated by spores or division. Dividing the plant in spring is the easiest method for most gardeners. Carefully separate a portion of the fern, ensuring each division has a section of roots, and replant in moist, well-draining soil.
