Spring/summer bloomFrost tolerant
Sweet peas must have well drained soil, so dig deeply and enrich with aged manure or compost before sowing seeds. Erect a well-anchored trellis, vertical netting or other support for vines before planting. Sow seeds in full sun in cool early spring weather as early as the ground can be worked. In mild winters, where ground does not freeze, sweet peas can be planted in fall. Seedlings will form strong root systems, then overwinter to bloom vigorously in spring. Plant sweet pea seeds 1 inch deep and 2 to 3 inches apart. When seedlings are 2 inches tall, thin to 4 inches apart to allow plants room to mature.
