Northern Research and Demonstration Farm
The 2008 Home Demonstration Gardens featured heirloom versus hybrid tomatoes, personal or small watermelons, culinary herbs, cut/dried flowers, and green flowers. However, the unusually late and wet spring in most of the state delayed the tomatoes and watermelon so much that many field day attendees were not able to sample the fruit. Instead, attendees were asked to complete a brief questionnaire about their home gardening practices.
