🌱 How to Care for Garden Dahlia to Prevent Botrytis?
💧 How to Water
Water every 2-3 days during the active growing season, keeping the soil evenly moist but never waterlogged. Significantly reduce watering in winter when the plant goes dormant. Always water at soil level to avoid wetting the foliage and flowers, which can promote fungal diseases.
☀️ Lighting
Garden dahlia needs full sun: at least 6 hours of direct sunlight per day. A sunny position encourages abundant, vigorous blooming. In very hot climates, light afternoon shade can protect flowers from extreme heat.
🪴 Ideal Soil
Use well-draining, fertile soil enriched with organic matter such as compost or well-rotted manure. Ideal pH ranges from 6.0 to 7.5. Avoid heavy clay soils that retain excessive moisture, as they can rot tubers.
