Sweet Peas thrive in fertile, organically rich, well-drained soil. Start 2-3 seeds per hole as soon as the soil can be worked (about 4-6 weeks before the last frost date in cooler climates). When the seedlings are 3-4 inches tall, thin to 1 plant every 12 inches. Keep soil moist, watering at the base of the plant to avoid wetting foliage. Knee High Sweet Peas do not need support. The bushy plants will produce long, straight stems with 5-6 inch florets filled with colorful, long-lasting flowers.
In warmer climates sow sweet pea seeds in the fall for beautiful winter and spring blooms.
Extend the flowering season by regularly picking all of the flowers from your Sweet Pea plants. In warm weather Sweet Pea flowers will rapidly develop seed pods (usually within 10-12 days of blooming) that drain energy from the plant and trigger more seed production at the expense of flower production. By picking all of the flowers before the pods develop you'll encourage new flower growth, extend the flowering season, and of course have bountiful, beautiful flowers for display around the house!
For maximum growth plant seeds at the bottom of a 6" trench with soil until the ground is level beneath the growing plants.
Wit & Wisdom: Gather the flowers in the morning when the dew is still on them. This is when their scent is the sweetest. Read The Old Farmer's Almanac Sweet Pea Growing Guide!
Help Your Plants Thrive with Weed Control: Weeds compete with vegetables, flowers and other plants for water, space and nutrients. Give your plants their best life by keeping weeds under control with Organic Weed Barrier Paper, mulch or careful weeding.
