When to Seed Sweet Pea
This annual flower should be transplanted or direct seeded into the garden once all major danger of frost has passed. Unlike many other annuals, sweet peas prefer to germinate in cooler soils. They can be planted several weeks before the last frost date.
Where to Plant Sweet Pea
Choose a spot that gets full sun to partial shade and has loose, well-draining soil. It will require a trellis or something to climb on.
Growing Sweet Pea
Sow seeds one inch deep and three inches apart. This seed will benefit from scarification ahead of planting. If direct seeding, once your seedlings start germinating, thin them to six to 12 inches apart. If your growing location doesn’t have the most nutrient dense soil, mix in plenty of organic matter ahead of planting, or consider fertilizing throughout the growing season.
Harvesting Sweet Pea
Sweet peas are not harvested for food, as all parts of the plant are poisonous. It is grown mainly as an ornamental and is beloved by hummingbirds.
