Sweet chestnut orchard production

ChestnutsWelcome to Michigan State University’s new edible chestnut website! Edible sweet chestnut orchards have sprung up across Michigan over the last 20 years. In fact, as of 2007 Michigan had the largest number of chestnut growers and the most acreage of any state in the United States. As a result of this enthusiasm for the edible chestnut, a number of resources to support producers have been developed by MSU. This website will act as a clearinghouse for all chestnut-related content produced by MSU.  New to chestnuts?  Be sure to read the important information about new discoveries regarding internal kernel breakdown under the establishing orchards link to the left.  

Be sure to visit the Rogers Reserve webpage to learn about the endowed, 100-acre chestnut agricultural research station in Michigan’s Jackson County. For more news and to search our archives, visit MSUE Fruit & Nuts.
