🌱 How to Care for European Cyclamen to Prevent Gray Mold (Botrytis Blight)?

💧 How to Water

Water every 7 days, preferably by placing the pot in a shallow dish of water for 20-30 minutes and allowing the soil to absorb moisture from the base. Avoid wetting the leaves and tuber directly to prevent rot. Reduce watering frequency in summer during dormancy.

☀️ Lighting

Place in bright indirect light or dappled shade, near a north- or east-facing window. Avoid intense direct sunlight, which can scorch the leaves. The plant naturally grows in dappled forest shade, so mimicking this environment works best.

🪴 Ideal Soil

Use well-draining soil rich in organic matter, with a pH of 5.5-6.5 (slightly acidic). A mix of equal parts potting soil, peat or coco coir, and perlite works well. Ensure the pot has adequate drainage holes to prevent waterlogging of the tuber.
