How to Grow Black-Eyed Peas (Cowpeas)

Black-eyed peas (cowpeas) are the heat-lover's legume — they produce abundantly in the same July-August heat that kills snap beans. Direct sow only after soil is genuinely warm (65°F+); cold soil causes rot. As legumes, they fix atmospheric nitrogen in the soil, improving fertility for the next crop. Harvest for fresh 'shell peas' when pods are plump but still green, or let pods dry on the plant for dried peas. The traditional Southern New Year's Day dish of black-eyed peas for good luck started as a practical matter — they were the dried legume most readily available from the garden.

Direct Sowing

Black-Eyed Peas (Cowpeas) can be direct sown 3 weeks after your last frost date. Plant seeds 1" deep, spaced 6" apart.

Growing Tips

Thrives in heat that kills snap beans. Direct sow only — don't transplant. Improves soil through nitrogen fixation. Harvest pods green for fresh peas or let dry on the plant for dried peas.
