How to grow black eyed peas in containers from seed?
Growing black-eyed peas in containers from seed is quite easy and productive! I do this on my patio every summer:
Choose containers at least 12 inches deep and wide - these plants develop substantial root systems. Use well-draining potting mix with extra compost for nutrients.
Sow seeds 1 inch deep, 4-6 inches apart after danger of frost has passed and soil is warm. They need full sun (6+ hours daily) for best production. Water consistently, especially when flowers and pods are forming.
They're relatively drought tolerant once established. Support may be needed for some varieties. Harvest when pods are well-filled but before they dry completely if eating fresh. For dried beans, allow pods to dry on plants.
You'll get a surprising yield from containers! The flowers are pretty and attract pollinators too.
