Why are there fans on a pear orchard?

Fans in a pear orchard are typically used for frost protection and to improve air circulation. During late spring, when blossoms are vulnerable to frost, fans can help mix warmer air from above with cooler air at ground level, reducing the risk of frost damage. Additionally, fans can promote better pollination and fruit development by enhancing airflow, which supports the health of the trees and the quality of the Pears.
