Sweet peas are a beautiful flower to have in your garden. They bloom early in the spring, produce flowers over a long season, and smell amazing! It is early September now and my sweet peas are finally done for the year. Read on to learn how easy it is to save your sweet pea seeds for beautiful blooms year after year.
When to Harvest Sweet Pea Seeds
Sweet peas seeds are ready to harvest when the pods are fully dry. For me this happens around late August to early September. The pods will turn brown and brittle and you may even be able to hear the seeds rattling around inside.
Make sure you harvest your sweet pea seeds as soon as most of the pods look ready. If you wait too long, the pod will split open and the seeds will scatter on the ground.
How to Harvest Sweet Pea Seeds
Collect the dry pods from the plant and place them on a work surface. With your fingers carefully open up each pod, remove the seeds, and drop them into a small bowl. The seeds should be large, hard, and dark brown or black in color. Discard any seeds that are soft or white because these are not fully mature and will not germinate properly.
When to Plant Your Seeds
Your sweet pea seeds can either be planted in the late summer/early fall if you plan to overwinter them or they can be saved and planted the following spring. Since we rarely have harsh winters here in Oregon, I usually plant my seeds in mid to late September. The peas are able to grow about a foot tall before going dormant for the winter. In the spring they have a head start on the season and start blooming earlier.
Store Your Seeds
If you choose to store your sweet pea seeds keep them in an airtight container. This could be a zip top bag or a mason jar with a tight fitting lid. Keep them in a dark and cool place and plant them in the spring as soon as the soil can be worked.
Hope you get to include these beautiful flowers in your garden again next year. Happy Gardening!
