In this article, we’ll show you how to save spinach seeds and enjoy a bountiful harvest year after year.

Planting Spinach and Growing Conditions

Harvesting Spinach Leaves

To encourage seed production, harvest spinach leaves regularly. As the plants grow larger, pick the outer leaves for salads and use the mature leaves in soups or as a side dish. Be sure to leave a few plants untouched to allow them to grow, mature, and flower. This will be essential for seed production.

Allowing Spinach to Flower and Set Seeds

As the season progresses, the female spinach plants will send up flower stalks from the middle of the plant. The male plants may also produce some flowers, but it’s the female plants that will set seeds. Simply let the plants be and enjoy the beautiful flowers.

Harvesting the Seeds

Once the flowers fade, the seeds will begin to set. Allow the flowers to dry on the stalks, and over the next few weeks, the seeds will develop. You’ll notice a mix of different-sized seeds. Keep an eye on them, and when they begin to dry, it’s time to harvest them.

You can either remove the entire flower stalks or let the seeds continue drying on the stems. Just make sure to collect them before they start falling to the ground. Snip the stalks with garden scissors and place them in a paper bag. If seeds start falling, put a paper bag over the seed head, close it, and then cut the stem.

Drying and Storing Spinach Seeds

To ensure the seeds are properly dried, tie a string around the bag and hang it up. Air drying is the easiest method, so allow the bag to hang undisturbed for a couple of weeks.

After the drying process, it’s time to separate the seeds from any remaining plant material. Hold one bowl below the other and pour the seeds from one bowl to the other. The breeze will catch the lightweight leaves and blow them away, while the heavier seeds will fall into the lower bowl.
