🌱 How to Care for Hare's-foot Fern to Prevent Fungus Gnats?

💧 How to Water

Water every 6-8 days when the top of the substrate is slightly dry. The best method is to submerge the pot in water for a few minutes, allowing the rhizomes and roots to absorb moisture evenly. Use filtered or rainwater to avoid lime buildup.

☀️ Lighting

Prefers bright indirect light. It tolerates shadier spots but grows best near north- or east-facing windows. Avoid direct sunlight which can scorch the delicate fronds.

🪴 Ideal Soil
