🌱 How to Care for Swordfern to Prevent Mealybugs?

💧 How to Water

Keep the substrate constantly moist but never waterlogged — water when the top layer of soil begins to feel dry to the touch, generally every 2-3 days in indoor environments. Avoid saucers with standing water, as excess moisture promotes root rot.

☀️ Lighting

Prefers filtered or indirect light and partial shade, such as under a tree canopy or near windows without direct sun. Intense direct sunlight burns and dries out the fronds; too little light results in weak and sparse growth.

🪴 Ideal Soil

Use a substrate rich in organic matter and well-drained — a mix of potting soil, coconut fiber or peat moss, and perlite works well. A slightly acidic to neutral pH (around 5.5 to 7.0) is ideal.
