Heat Stress in Peaches and Apples: What does it look like, how does it happen, and what can I do? (2025)

Brent Black, Utah State University Extension

Description: In the past few years, we’ve had multiple incidents where peach and cherry trees experienced high incidence of “double” or “twin” fruit. As it turns out, these fruit deformities are the result of earlier heat or drought stress. This presentation will explore what this looks like, when the heat stress occurred and what orchardists need to watch out for in order to reduce future problems.
