🌱 How to Care for Heart Fern to Prevent Scale Insects?

💧 How to Water

Water when the top layer of the soil dries out slightly, usually 2-3 times a week. Use soft, filtered, or boiled water at room temperature and pour it directly onto the substrate rather than the leaves to reduce the risk of fungal diseases.

☀️ Lighting

Place the plant in a spot with bright, indirect light or partial shade—a north or east-facing window is ideal. Direct sunlight quickly causes burns on the delicate, heart-shaped leaves.

🪴 Ideal Soil

Use a well-draining, slightly acidic mix of peat and perlite that provides good water retention while allowing drainage; a drainage layer at the bottom of the pot should be at least 1 inch (3 cm) thick.
