Beans (Green/Snap) in Missouri's Climate
Your climate is classic bean country. Direct sow from mid-May when soil warms to 60°F. Succession plant bush beans every 2 weeks through mid-July for continuous harvest. Your warm, humid summers are ideal for bean production — just watch for Mexican bean beetle and Japanese beetle, which are common in the mid-Atlantic and Midwest.
Soil Considerations for Missouri
Rich loess soils along Missouri River. Rocky Ozark soils in south. Heavy clay common. Generally fertile. Make sure soil has warmed to at least 60°F before planting beans (green/snap) outside.
Missouri Climate & Growing Season
Continental climate. Hot, humid summers. Four seasons. Good growing season in most of state. Beans (Green/Snap) cannot tolerate any frost, so wait until all frost danger has passed before transplanting outside. Watch local forecasts carefully in spring.
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 beans (green/snap) — transplant timing shifts by several weeks across the state.
Growing Tips
Direct sow only — beans don't transplant well. Inoculate seeds with rhizobium for better nitrogen fixation.
