ðą How to Care for European Cyclamen to Prevent Gray Mold (Botrytis Blight)?
ð§ 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.
âïļ 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.
ðŠī 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.
