Expand your knowledge of vegetable production at the 2026 Great Lakes Fruit, Vegetable, and Farm Market Expo
This year’s schedule is packed with educational opportunities for vegetable growers.
The Great Lakes Fruit, Vegetable, and Farm Market Expo, also known as the Great Lakes Expo or GLEXPO, is one of the leading fruit, vegetable and farm market events in the Midwest. This annual event features educational sessions on important industry topics, a large trade show for networking and discovery, and other specialized workshops and meetings. This convention has been held annually since 2001 and has been a consistent favorite among growers and other ag professionals across the country.
Each year the event features a robust agenda of vegetable programming organized by Michigan State University Extension. The educational presentations cover a wide range of crops, offering something for everybody when it comes to learning about new developments in the vegetable industry. Many of the sessions are also worth Michigan and Ohio restricted use pesticide credits and certified crop adviser credits in various categories.
The event this year will be held at the DeVos Place in Grand Rapids, Michigan, from Dec. 8-10, 2026.
The following is further information on the vegetable sessions offered at the 2026 Great Lakes Expo. These are highlights for vegetable producers and by no means constitute the complete program. Many other educational sessions centered on fruit, greenhouse production, farm marketing and other areas of specialty crop production will be offered as well.
To view the full agenda and find more information, please visit the GLEXPO website.
