🌱 How to Care for Mexican Tree Fern to Prevent Spider Mites?

💧 How to Water

Water the substrate every 3–5 days in summer (weekly in winter) and also wet the fibrous trunk regularly—it acts as a moisture reservoir and must never dry out completely. Avoid pouring water directly into the crown on cold days to prevent rot.

☀️ Lighting

Prefers filtered light or partial shade, replicating a cloud forest understory—less than 30% full sun. Direct sunlight burns and bleaches the delicate fronds.

🪴 Ideal Soil

Use a rich, well-draining substrate: organic compost or leaf mold, coconut fiber or peat moss, perlite or pumice, and orchid bark, with a slightly acidic pH (5.5–6.5). The pot needs generous drainage—large pots should have multiple openings and be elevated off the ground.
