Madison's Average Last Frost
2026-05-10 | WI
…but keep your eye on the weather before planting. Madison has a notorious reputation for late May frosts. Many local old-time gardeners refuse to plant, especially their tomatoes, peppers, morning glories, etc. until Memorial Day weekend when the soil has warmed properly. Novice gardeners have a tendency to plant too early!

Willy Street Park Plant Sale
2026-05-02 09:00 - 14:00 | Willy Street Park, 1002 Williamson St., Madison, WI, 53703, United States
Over 40 years ago, a dedicated group of neighbors came together to preserve what is now Willy Street Park, successfully preventing its development into a fast food restaurant. Today, the Willy Street Park Society is collaborating with the Wisconsin State Historical Society to create an archive and oral history of the park, preserving its rich legacy for future generations.
Though Willy Street Park remains private land, it operates much like a public park, welcoming all. But because it’s maintained by the not-for-profit Willy Street Park Society, the park doesn’t receive the same city funding and maintenance as public parks. Neighbors are invited to take an active role in keeping the park beautiful—whether by picking up litter during visits or volunteering for a variety of tasks, from gardening to administrative support.
