🌱 How to Care for Pear to Prevent Anthracnose?

💧 How to Water

Water pear trees approximately every 7 days during dry periods, providing about 1 inch (2.5 cm) of water weekly. Established trees tolerate some drought but consistent irrigation improves fruit quality. Avoid waterlogged soil as roots are sensitive to excess moisture.

☀️ Lighting

Pear trees require full sun — at least 6 to 8 hours of direct sunlight per day. Insufficient light reduces fruit production and increases disease susceptibility. Plant in open, sunny locations away from shade.

🪴 Ideal Soil

Pear trees prefer deep, well-drained loamy soil rich in organic matter, with a pH between 6.0 and 7.5. Avoid compacted or waterlogged locations. Incorporate compost before planting to improve soil structure and fertility.
