1. Understanding Sweet Peas Sweet peas, with their enchanting fragrance and vibrant colors, have been grown by gardeners for generations. Originating from the Mediterranean region, these climbing plants are scientifically known as Lathyrus odoratus. They are annuals, meaning they complete their life cycle in one growing season.
2. Choosing Your Seeds There's a vast array of sweet pea varieties to choose from. Whether you prefer the pastel shades or the bold and bright ones, there's a sweet pea for every palette. Look for seeds at your local garden center or online. We like to source from small farms for our seeds, and we offer a selection in our online store as well.

3. Sowing Seeds Sweet peas thrive in cooler temperatures, so it's best to start them early in the season. You can sow them directly in the ground or start them indoors if your area experiences late frosts. Here's a quick how-to:
- Soak the seeds overnight to soften their hard outer coating or use the pre-sprouting method like we do, pictured above.
- Plant them about an inch deep in well-draining soil.
- Space the seeds about 2-3 inches apart.
4. Location, Location, Location Choose a sunny spot for your sweet peas. They love at least 6 hours of sunlight a day. However, their roots prefer cool, moist soil, so consider mulching around the base to retain moisture and regulate soil temperature.
5. Support System Sweet peas are climbers, so they'll need something to cling to. Install trellises, netting, or even some sturdy strings for them to twine around. This support should be in place at planting to avoid disturbing the roots later.
6. Watering and Feeding Keep the soil consistently moist, especially during dry spells. Avoid overhead watering to keep the foliage dry and reduce the risk of disease.
7. Pinching for Bushier Plants When your sweet pea plants are about 6 inches tall, pinch out the tips. This encourages bushier growth and more blooms.
8. Pests and Problems Watch out for pests like aphids and mildew. Regular inspections and good air circulation around your plants will help keep these issues at bay. We find the best way to avoid these problems is excellent soil health and planting shrubs and trees on our farms that attract birds.
9. Harvesting the Blooms Sweet peas are excellent cut flowers. The more you cut, the more they bloom! Regular harvesting also prevents them from going to seed, prolonging the flowering period. Cut flowers weekly and fill your house with these beautiful fragrant flowers and give bouquets to family and friends to keep your plants producing.

Sweet peas will fill your garden with a sweet scent and a burst of color that's sure to become a haven to escape to throughout the spring and early summer, at the end of the season you can allow the sweet peas to go to seed and collect the full and dry pods to save seed for next year.
Growing sweet peas is not just about beautifying your garden; it's about creating a space of joy and tranquility you can escape to every day. So, grab those seeds and let the magic of sweet peas transform your garden space this season.
