Improving Pollination and Fruit Set in Highbush Blueberry

Improving pollination and fruit set in highbush blueberry is a major area of focus in our blueberry research and outreach program. We have primarily focused on biological approaches to improve fruit set, berry size, and yields, but have also studied the role of different chemical nutrients on improving fruit set, berry retention, and yield. Please see the following final and progress reports for information.
