🌱 How to Care for Asian Pear to Prevent Aphids?

💧 How to Water

Water deeply once a week during the growing season (more often in hot, dry spells), letting the top few centimeters of soil dry between waterings; reduce watering in autumn and winter.

☀️ Lighting

Give it at least 6-8 hours of direct sun a day — full sun produces the best flowering and fruit; too much shade lowers yield and increases disease risk.
