Calderwood speaks with Ellsworth American about colorful fall blueberry fields
The Ellsworth American spoke with Lily Calderwood, University of Maine Cooperative Extension wild blueberry specialist and assistant professor of horticulture, about the vibrant red and orange blueberry fields seen in Down East Maine during the fall. Calderwood explained that wild blueberry plants are similar to deciduous trees in that they release chlorophyll in the fall when temperatures drop. “When the green from the chlorophyll comes out of the leaves, you have the red and orange color left behind,” she said.
