  • Important update related to COVID-19

    • As Missouri COVID-19 restrictions ease, MU Extension is resuming some face-to-face operations. Faculty and staff are delivering programs and services in our community while striving to follow CDC guidelines to keep you and ourselves safe. Please follow any guidance posted on this page or at our office.

    Help save the gardens

    Thousands of visitors pass through the St. Charles Extension Center on Brown Road each year. However, increased flooding and erosion along Dardenne Creek the past few years now threatens the property.

    We have a solution – working with the City of St. Peters, we are embarking on a project that will save our property and stabilize the banks of Dardenne Creek. By partnering with the city, we can cut the cost of this essential project in half. But we have to move now. That’s why we come to you today. We would like to ask you to give in order to Help Save the Gardens for St. Charles Countians.

    Your donation is tax deductible.* Please make checks payable to the St. Charles County Extension Council and indicate “Help Save the Gardens” in the notes. If you have questions on ways to Help Save the Gardens, please call Alex at 636-970-3000. Donations may be sent to: MU Extension at 260 Brown Rd, St. Peters, MO 63376.
