🌱 How to Care for Pomegranate to Prevent Bacterial Blight?

💧 How to Water

Water deeply every 7-14 days during the growing season. Allow the soil to dry out between waterings. Pomegranate is drought-tolerant once established but benefits from consistent moisture during flowering and fruiting. Avoid waterlogging to prevent root rot.

☀️ Lighting

Pomegranate requires full sun — at least 6 hours of direct sunlight per day. Insufficient light leads to poor flowering and fruit production. Place outdoors in the sunniest spot available.

🪴 Ideal Soil

Plant in well-draining soil with a pH of 5.5-7.5. Sandy loam or amended garden soil works well. Avoid heavy clay without amendments. Add organic compost to improve fertility and drainage.
