I recently learned about seed saving via a Kickstarter trailer for a documentary entitled, Seeds: The Untold Story. What is seed saving, you say? It's exactly what it sounds like! It is the process of saving seeds for future harvests, a process that has been done for over ten thousands years.
The seed saving practice has been especially crucial in recent years while many plants have increasingly become endangered. In the last century, 94% of seed varieties have been lost. Hard to believe, right? Industrial agriculture following the industrial revolution has played a big role in the demise of this wonderful art.
Check out this trailer for “Seeds: The Untold Story” to learn more about this lost art:
Just like the trailer mentions above, corporate greed in industrial agriculture has created a monopoly over seeds. Corporations prefer crops that ripen all at once, such as hybrid plants, whereas heritage plants ripen unevenly are purer.
How to Start Saving Seeds
The process of seed saving can be very simple, as long as you know your plants. Some common edibles may appear very different when they flower and then go to seed. Leaves change shape; stalks shoot skyward or downward; flowers contrast with leaves. As you become comfortable with recognizing a plant's colors, shapes and sizes, you can start mixing varieties.
To begin saving seeds, you must also become familiar with the life cycle of each plant, as well as how it is pollinated:
The pollination process occurs within each flower, and is not transferred from one flower to another, either on the same plant or between plants.
The wind or an insect carries the pollen and fertilizes one flower to another flower, either on the same or another plant.
An annual plant completes its life cycle, from germination to the production of seed, within one year, and then dies, such as lettuce and tomatoes.
Lettuce produces hundreds of small yellow flowers atop its stalk, the site of feathery little seeds. The seeds are similar to dandelion seeds, having a tiny parachute perfect for riding the wind. The plants can be tipped into a container and shaken to release the seeds.
Tomatoes should be picked when they are really ripe to prevent bacteria from persisting through the seed. In the bottom of a bucket, mush the tomatoes and squish from the pulp as many seeds as possible. Add water, place the lid on the bucket and let ferment for about three days. Hose back into the bucket whatever seeds are still attached to the tomato meat and discard the pulp. The pulp floats but the seeds do not. After the tomato pieces have been rinsed, pause for a few seconds as the last of the seeds sink to the bottom. Pour the liquid out of the bucket and you will find the tomato seeds at the bottom. Pour clean water over the seeds and onto a mesh screen to collect the seeds. Dry!
A biennial plant is harvested as food in their first summer or fall, and do not produce seed until the following year, such as carrots and beats.
Carrots are cross-pollinated by insects and can be harvested in the fall. They often cross with Queen Anne's Lace, so keep it clipped so as not to flower at the same time as the carrot. The flower head on the carrot, or seed umbel, matures unevenly, and is best to harvest when secondary heads have ripe brown seed. This is usually around September of the second year. Heads can be removed as they mature or entire stalks can be cut and cured for a few weeks. Rub off seeds when completely dry and use a screen to remove the chaff.
Beets are cross-pollinated by the wind. Therefore, it is best to raise seed of only one variety each year. In summer, when plants are dry, brown mature seeds are easily stripped by hand from the branches. Beet seeds are actually seed balls, containing up to six seeds each.
Perennial plants both live and bear seed every year. Generally, the top portion of the plant dies in the fall and winter and regrows in the Spring from the same root system. These are typically flowers you will find in your garden. Most of these flowers are cross-pollinated by insects. If you wish to preserve the purity of a certain plant for seed saving, grow only one variety at a time.

Tips to Harvesting Seeds
- After harvesting, allow the seeds to dry for a few more days. The larger the seed, the longer the drying period.
- Spread seeds on plates, screens, wax paper, or newspaper in a breezy place for a few days. They should be rotated and spread out during that time.
- You may dry the seeds in a sun-exposed room, in a non-humid greenhouse or in the sun outside if they are covered or brought in at night to expedite drying.
- Seed should always be stored in cool, dry conditions.
- Temperatures below freezing will not harm seeds if they have been adequately dried. You may also store them in the freezer to prolong their lives.
- Sealing most seeds from air, except for beans and peas which need air circulation, also prolongs the life of the seed.
- Store seeds in airtight tins, glass jars or plastic containers that can be closed to make them moisture proof.
