Planting & Care

Sow sweet pea seeds outdoors in early spring, as soon as the soil can be worked, or start indoors 4-6 weeks before the last frost. Soak seeds in water for 24 hours before planting to improve germination. Plant seeds about 1 inch deep and 2-3 inches apart. Provide a trellis or support for the vines to climb. Keep the soil evenly moist but not waterlogged. Mulch to retain moisture and suppress weeds. Fertilize lightly when plants are young. Deadhead spent flowers to encourage continued blooming.

Sweet peas prefer cool weather and may stop blooming in hot summer temperatures. In warmer climates, plant in fall or early spring for best results. Monitor for pests like aphids and diseases such as powdery mildew, and provide good air circulation.
