Agriculture is important to Iowa. We grow crops and raise livestock to feed our nation and beyond. Much of Iowa’s economy thrives on our rich agricultural heritage and ANR Extension and Outreach plays an important role in providing research-based information and resources to educate Iowa’s farmers, producers and agribusinesses. Our programs impact all Iowans, whether they live in a rural or urban area, and have been developed to improve our quality of life.

The mission of the Iowa State University Extension Master Gardener Program is to provide current, research-based, home horticulture information and education to the citizens of Iowa through programs and projects. Through their participation in educational activities, Master Gardeners also increase their own personal knowledge in horticulture. Master Gardeners extend Iowa State University Extension’s consumer horticulture education programs through volunteer activity.
