Beating the Heat and Mulching in Raspberries (2025)

Lisa DeVetter, Washington State University

Description: This presentation will cover two topics related to improving red raspberry production: 1) the use of soil-biodegradable and non-biodegradable plastic mulches as an establishment tool for new plantings and 2) impacts of various heat mitigation strategies on yield, fruit quality, and overall plant stress. Specific heat mitigation technologies that will be covered includes biostimulants, evaporative cooling using microsprinklers, and shade cloth.
