Research Topic: Invasive plant management, native plant pollen/nectar sources, Aronia melanocarpa
Overview of Research: I conduct applied research that responds to production and management need of Maine’s ornamental horticulture industry. My current projects include assessment of Aronia melanocarpa production in New England and assessment of introduced and native plants as pollen/nectar sources for native bees and honeybees. I work extensively with the green industry in New England. Extension projects include editorship of the biennial New England Greenhouse Floriculture Guide, collaborative planning of the Northeast Greenhouse Conference and the New England Grows trade show, collaboration on economic impact surveys of New England’s green industry, and development of topic-focused educational programs for Maine’s green industry.
