🌱 How to Care for Wart Fern to Prevent Fungus Gnats?

💧 How to Water

Water when the top layer (2–3 cm or 1 inch) of the substrate begins to dry, generally every 3–5 days in summer and less frequently in winter. Use room temperature water and avoid wetting the fronds directly to prevent fungal diseases. Never leave the pot waterlogged — excess water is the main cause of root rot.

☀️ Lighting

Prefers bright indirect light or partial shade. Thrives near north-facing windows or several feet away from south-facing windows. Avoid direct sun, especially during the hottest parts of the day, as it burns the leathery fronds. In gardens, plant under the shade of trees or structures that filter light.

🪴 Ideal Soil

Use an organic-rich, well-draining, and slightly acidic substrate, with a pH between 5.5 and 6.5. A mix of peat, pine bark, perlite, and sphagnum moss is ideal. Ensure that the rhizomes remain on the surface of the substrate, not buried, to ensure good oxygenation and prevent rot.
