The challenges facing the flower industry have changed throughout the last 60 years, and with these changes, AFE has redirected research efforts adapting to the needs of the community that we serve. As opportunities developed from these challenges, AFE supported research to enhance product quality, share best practices, and improve profits leading to a more successful floral industry. Many projects have been funded at universities and colleges across the U.S. through the years. Results from these projects have led to new production practices, postharvest & shipping procedures, reduced losses from pest & diseases, and improved longer lasting flowers. 

AFE funded research has transformed the floral industry as we know it today and resulted in improved quality of flowers reaching consumers.

Let’s take a look at AFE-funded research focuses and achievements decade by decade:
