Peas are a cool season vegetable best planted outdoors in the fall, but can be grown indoors with a consistent temperature year round. Heat tolerant varieties are available as well, says the University of Illinois Extension. Peas grow in a small amount of space, making yields from containers more exceptional than that of larger vegetables. Garden peas, Big Oregon Trail, Snow Peas, Sugar Pod and Snap peas are all acceptable varieties for containers.
Fill your container with a potting mixture that has been moistened with water and a complete water soluble fertilizer, recommends Oregon State University. Potting soil does not contain a lot of nutrients and requires frequent fertilization. Water soluble fertilizer is applied once a week for the best results.
Plant your peas in the soil at a depth of 1 to 1 1/2 inches deep in either single, or double rows recommends the University of Illinois. Allow 8 to 10 inches between double rows when planting in containers to prevent crowding of the plant roots.
Water the seeds and avoid fertilizing while the seeds are germinating, as this may damage the seeds, says the University of Illinois.
Apply a mulch to the top of the soil to keep it cool, recommends the University of Illinois. This will promote pea growth, emulating outside soil temperatures.
Water the soil to keep it from drying out. Containers drain water quickly. Use a moisture meter to get an idea of how long the container can go without water, suggests Oregon State University.
Place a small container trellis in the container for the beans to grow up. Place the shoots of the plant on the trellis as it grows to promote good vegetable growth. Harvest according to the time required for your pea variety to mature properly.
