Step-by-Step Growing Guide
Black-eyed peas (Vigna unguiculata) are a quintessential warm-season legume requiring soil temperatures of at least 65°F — ideally 70–95°F — before sowing. They fix atmospheric nitrogen via root nodules (inoculate seed with cowpea-specific Bradyrhizobium inoculant for best results in new plots). Sow seeds 1 inch deep and 4–6 inches apart in rows 24–36 inches apart directly in the garden after all frost risk has passed. They prefer well-drained, moderately fertile soil with a pH of 5.8–7.0 — excessive nitrogen from fertilization will produce lush vines with poor pod set. A single pre-plant application of phosphorus and potassium (without nitrogen) is ideal. Water moderately at 1 inch per week; once established, black-eyed peas exhibit exceptional drought tolerance. Bush types need no support; vining types need a trellis or fence. Plant a succession every 3 weeks through midsummer for continuous harvest.
