Growing Beet in Minnesota: Complete Guide
Beet (Beta vulgaris) is a crop that grows best when sown directly in the garden. In Minnesota, the right time to direct sow is around Sunday, March 29, 2026, once soil temperatures are consistently warm enough for germination.
Because Minnesota stretches across 5 USDA hardiness zones (3a, 3b, 4a, 4b, 5a), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.
With 55 days to maturity, Beet fits comfortably within Minnesota's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.
Beet requires full sun to partial shade and regular (1 inch/week) moisture. Most of Minnesota receives adequate sunlight during the growing season, though gardeners in humid eastern regions should watch for fungal issues and ensure good air circulation.
