🌱 How to Care for Indian Hawthorn to Prevent Anthracnose?

💧 How to Water

Water deeply once or twice a week during the first growing season to establish roots, letting the top 3-5 cm of soil dry out between waterings. Once established, reduce to every 10-14 days, and rely on rainfall during cool or rainy periods - overwatering and poor drainage are the main triggers for root problems and fungal leaf spot.

☀️ Lighting

Plant in full sun for at least 6 hours of direct light daily. Full sun produces the densest growth and heaviest bloom and also keeps foliage dry enough to resist Entomosporium leaf spot; light afternoon shade is tolerated in hot climates but increases disease risk.

🪴 Ideal Soil

Use well-draining, slightly acidic to neutral soil (pH 5.5-7.0) - sandy or loamy garden soil amended with compost works well. Avoid heavy, waterlogged clay, and ensure good air circulation around the base of the shrub to keep leaves dry.
