🌱 How to Care for Tulip to Prevent Pythium Root Rot?

💧 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.

☀️ Lighting

Plant in a location with full sun, receiving at least 6 hours of direct sunlight per day. Full exposure ensures firm stems and vibrant flowers. Partial shade results in weak plants with reduced flowering.

🪴 Ideal Soil

Prefers sandy or loamy soils, well-drained and enriched with organic matter. The ideal pH ranges between 6.0 and 7.5. In clay soils, incorporate coarse sand or perlite to improve drainage and prevent bulb rot.
