🌱 How to Care for European Fan Palm to Prevent Scale Insects?

💧 How to Water

Water every 7-10 days in summer, allowing the top 2 inches of soil to dry between waterings. Reduce to every 14-21 days in winter. Avoid waterlogged soil — root rot is the most common problem. Use filtered or rain water if possible to avoid chlorine and fluoride buildup.

☀️ Lighting

Place in full sun with at least 6 hours of direct sunlight daily. Indoors, position near a south- or west-facing window. Insufficient light will further slow its already very slow growth rate.

🪴 Ideal Soil

Use a well-draining, sandy or loamy mix with a pH of 6.0–8.0. A blend of potting soil, coarse sand, and perlite works well. Tolerates calcareous and slightly saline soils. Avoid heavy clay that retains moisture.
