Over 1,500 volunteer Master Gardeners in New York State (over 40 in Yates County) contribute educational services to meet the outreach mission of Cornell, influencing many thousands of consumers on horticultural issues.
Master Gardeners present hands-on workshops and research-based information for low-income county residents at their community gardens, housing development gardens, and school gardens. Contact information page.
