🌱 How to Care for Star-of-Bethlehem to Prevent Bacterial Wilt?

💧 How to Water

Water once a week during spring (active growth). Gradually reduce after flowering and stop completely in summer when the plant enters dormancy. Never let the soil become waterlogged — excess moisture is the primary cause of bulb rot.

Prefers full sun with at least 6 hours of direct sunlight per day. Tolerates partial shade but flowering will be less abundant. More sun equals more spectacular spring blooms.

🪴 Ideal Soil

Plant bulbs in well-draining, sandy to loamy soil with a pH between 6.0 and 7.5. Avoid clay or poorly draining soils. Add coarse sand or perlite to improve drainage if needed.
