Plant Profile: Pisum sativum

The garden pea is a cool-season crop cultivated for its edible seeds and pods. Both the pods and the seeds are significant food sources globally, and the flowers and tender shoots are also consumable. Additionally, peas contribute to soil health by fixing nitrogen; certain types, known as Austrian Winter Pea or Pisum arvense, can serve as effective cool-season cover crops.

Peas thrive in full sunlight and require moist, well-drained soil. They can adapt to various soil textures as long as drainage is adequate, preferring a pH level between 6 and 7.5. While they can manage in partial shade, full sun is essential for optimal flowering and fruiting.

There are two main types of peas: tall, vining varieties that produce continuously throughout the season and shorter bush varieties that yield a single crop at once. Vining types benefit from support structures like trellises, stakes, or metal fences to reduce disease risk. Additionally, different varieties influence the shape of the seeds and pods—garden peas have round, starchy seeds and fibrous pods, snow peas are harvested with immature seeds, and sugar snap peas feature juicy, green-bean-like pods with nearly mature seeds.

As a cool-season crop, peas cease growth when temperatures exceed 85°F, which creates a limited growing period in North Carolina. Seeds should be sown directly into the soil once it has thawed, typically from late February to March, as young plants can withstand some frost. Care should be taken when handling seeds, as they are delicate and may have reduced germination rates if damaged. Seeds should be planted about 1 inch deep and spaced 2 to 3 inches apart. Peas can also be cultivated in containers with a minimum size of 2 gallons and a depth of 12 inches. In North Carolina, plants usually reach harvest readiness in about 60 days, around May or June. To extend the harvest season, plantings can be staggered by a week.
