Growing Parsley in Minnesota
Parsley in Minnesota's Climate
Parsley is one of your most reliable herbs — the biennial handles frost, grows through your moderate summers, and keeps producing from May through November. Start seeds indoors in February (parsley germinates notoriously slowly — 14-28 days). The plant is biennial: lush leaves year one, flowers and seeds year two.
Soil Considerations for Minnesota
Rich prairie soils in south and west. Rocky and thin soils in north. Generally excellent for gardening in southern half.
Minnesota Climate & Growing Season
Long, cold winters. Warm summers. Short but productive growing season with long summer days. Hardy varieties essential.
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 parsley — adjust your planting dates to match your specific region.
Growing Tips
