🌱 How to Care for Bird's Nest Fern to Prevent Thrips?

💧 How to Water

Water when the top inch of soil feels dry, typically every 7-10 days. Avoid pouring water directly into the central rosette as this can cause rot. Use filtered or distilled water if possible, as the plant is sensitive to chlorine and fluoride in tap water.

☀️ Lighting

Provide bright, indirect light or light shade. An east or north-facing window works best. Avoid direct sunlight which can scorch the delicate fronds and cause yellowing. This fern tolerates low light conditions but grows more slowly.

🪴 Ideal Soil

Use a rich, organic potting mix that retains moisture but drains well. A combination of peat moss (or coco coir), perlite, and orchid bark is ideal. The soil should be slightly acidic with a pH of 5.0-6.0.
