Container color can significantly impact root zone temperatures, water use, and overall plant growth. This presentation explores research on how black and white nursery containers influence potting media temperature dynamics, plant performance, and irrigation strategies. Speakers will discuss the effects of heat stress, the role of cyclic irrigation in temperature management, and practical recommendations for growers. Findings from studies in Oregon, Florida, and Tennessee will be shared, providing regionally relevant insights for nursery producers looking to optimize plant health and resource efficiency.
