Madison's Average Last Frost
2026-05-10
…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!
