Hello! We have an oval-shaped depression in the lowest part of our yard that is chronically soggy. It's at the end of the driveway and there is a drain there, but the water simply isn't draining, as it would pretty much have to go uphill. I was wondering if a rain garden might be a good solution, and if so, how do we get started? What plants would thrive in wet soil? We're in Dexter near the Hudson Mills Metropark, about a mile from the Huron River.

A wet site can be improved by using plants that grow in wet sites to pull up the water. Red-twig dogwoods are found in wetlands and can greatly help. If it is far enough away from the drain tiles of a house you could use an arctic willow (grows about 8 feet tall and 10 feet wide. Penn State has a great list of plants for wet sites: https://extension.psu.edu/trees-shrubs-and-groundcovers-tolerant-of-wet-sites
Also you could contact the Rain Garden staff at Washtenaw County. They can provide more information on whether a site would work for a rain garden. They have a link at: https://www.washtenaw.org/706/Request-a-Design-Visit
