When to Plant Beets in Minnesota
Two crops in one — eat the roots and the greens. Beets are cold-hardy and surprisingly easy.
The Short Answer
Minnesota Frost Dates
Your planting dates depend on which part of Minnesota you're in. Here are the frost date ranges by region:

|---|---|---|---|
| Northern Minnesota | 3a, 3b | May 15 - Jun 1 | Sep 5 - Sep 20 |
| Central Minnesota | 3b, 4a | May 5 - May 20 | Sep 15 - Oct 1 |
| Southern Minnesota | 4a, 4b | Apr 25 - May 10 | Sep 25 - Oct 10 |

Growing Beets in Minnesota
Beets in Minnesota's Climate
Beets grow beautifully in cold climates. Direct sow from mid-April — they germinate in soil as cool as 40°F. Fall beets from a July-August sowing taste sweeter after frost exposure. They tolerate clay soil better than carrots, making them the more practical root crop for gardeners without raised beds. Beets store for months in a root cellar.
Soil Considerations for Minnesota
Rich prairie soils in south and west. Rocky and thin soils in north. Generally excellent for gardening in southern half. Loose, well-drained soil is especially important for beets since the edible portion grows underground. If your soil is heavy clay, consider raised beds.
Minnesota Climate & Growing Season
Long, cold winters. Warm summers. Short but productive growing season with long summer days. Hardy varieties essential. Beets can handle frost well, which is an advantage in Minnesota's climate. You can push planting dates earlier in spring and extend into fall.
Growing season length varies across Minnesota: Northern Minnesota (3a, 3b) has a last frost around May 15 - Jun 1, while Southern Minnesota (4a, 4b) sees frost end around Apr 25 - May 10. This difference matters for beets — but beets handle frost well, so the timing difference is less critical.
Growing Tips
Each beet 'seed' is actually a cluster — thin to one plant after sprouting. Harvest at 1.5-3 inches for tender roots.
Companion Planting
