Serving Henry, Mercer, Rock Island and Stark Counties

University of Illinois Extension connects people and their local horticulture and environmental concerns with the tools they need to pursue meaningful change. Whether it’s landscape aesthetics, sustainable practices, food production, pollinators, or a myriad of other topics, Illinois Extension has the resources people need.

Our unit is served by Martha Smith horticulture educator. She shares her 28 years of experience through a wide range of horticulture education, programs, training and research to benefit the environmental health and sustainability of our state’s ecosystems. She is part of the Illinois Extension state horticulture team which also produces gardening websites, seasonal webinars and a YouTube channel to make horticultural information easily accessible to everyone.


From educational curriculum units to websites devoted to deeply exploring a single topic area, our resource collection represents best practices based on both proven and emerging research and the work of our professional education staff.
