Cowpea is a frost sensitive annual that prefers full sun and tolerates a wide variety of soils. Drought and heat tolerant once established.
Cowpea seed should be direct seeded outdoors once the danger of frost has passed. Sow seeds 1-2" deep and 2-3” apart. Seeds will sprout in 6-14 days. Thin seedlings so that mature plants are 2-4" apart. Plants may need some trellising, but if planted thickly should support themselves.
Cowpea can be harvested in approximately 55-75 days. Harvest when pods are plump and full for cooking immediately or allow pods to dry on the vine before harvesting for long term storage.
Cowpea is self-pollinating and will rarely cross, although it can happen. Like all legumes, the flowers are visited by honeybees and bumblebees, but only the bumblebees are heavy enough to be effective pollinators on the short stigma flowers. On plants being saved for seed, allow the seeds to dry on the plant for as long as possible, gather and continue to dry indoors with good air circulation and then separate seeds from the chaff. Store seeds in a cool dry place and they will remain viable for 4-6 yr.
