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

💧 How to Water

Water approximately once a week during active growth in spring, allowing the soil to dry slightly between waterings. After flowering, gradually reduce watering until ceasing when the foliage dries. Never leave the soil waterlogged — excess moisture causes bulb rot.
