Growing Peas in Missouri

Peas in Missouri's Climate

Peas are your first spring crop — direct sow 4-6 weeks before last frost. Production continues until temperatures consistently exceed 80°F, usually by late June. Fall peas from an August sowing produce well into October. Provide trellising for climbing varieties.

Soil Considerations for Missouri

Rich loess soils along Missouri River. Rocky Ozark soils in south. Heavy clay common. Generally fertile.

Missouri Climate & Growing Season

Continental climate. Hot, humid summers. Four seasons. Good growing season in most of state. Peas can handle frost well, which is an advantage in Missouri's climate. You can push planting dates earlier in spring and extend into fall.

Growing season length varies across Missouri: Northern Missouri (5b, 6a) has a last frost around Apr 20 - May 5, while Southern Missouri (6b, 7a) sees frost end around Apr 1 - Apr 15. This difference matters for peas — but peas handle frost well, so the timing difference is less critical.

Growing Tips

Direct sow as early as the soil can be worked. Inoculate with rhizobium for bigger harvests. Provide a trellis for climbing varieties.
