Spring/summer bloomFrost tolerant
Sow seeds directly in deep containers at least 12 inches in diameter, or rectangular window-boxes at least 6-8 inches deep once danger of hard frost is over. Sweet peas grow best in cool weather and can handle light frosts. In mild winter areas, plant in fall weather to overwinter for spring bloom. Always fill planting containers with well moistened, good quality, fresh potting soil before planting seeds 1 inch deep and 2 to 3 inches apart.
Space seedlings 3 to 4 inches apart when they are 2 inches tall, allowing room for plants to mature, but leaving 5 to 6 plants in a 12 inch diameter container.
