🌱 How to Care for European Pear to Prevent Anthracnose?

💧 How to Water

Water deeply every 7–14 days during the growing season, especially during dry spells. Young trees need more frequent watering to establish roots. Avoid waterlogging as pear trees are susceptible to root rot. Reduce watering in autumn as the tree goes dormant.

☀️ Lighting

European Pear demands full sun — at least 6–8 hours of direct sunlight per day. Plant in an open, unshaded position for optimal fruit production. Poor light results in weak growth and reduced fruiting.

🪴 Ideal Soil

Plant in well-draining, loamy to sandy loam soil enriched with organic matter. Avoid heavy clay that retains water. Ideal pH is 6.0–7.5. Incorporate compost at planting time to improve soil structure and fertility.
