How to Collect and Save Seeds



Why go to the bother of collecting all those tiny seeds? The first reason is thriftiness. No need for anything in your garden to go to waste. Compost, recycle, and re-use. The second reason is frugality.
Why buy new plants every year when you can grow your own for free? Even further, why buy unproven plants or seeds when you know the ones you are collecting from did well and obviously flourished in your yard.

Another reason to collect seeds is to ensure the propagation of heirloom varieties and rare, native plants that are not available through other means. Commercial growers and catalogs will often only carry the most popular plants and seeds. By collecting seeds from particular flowers and edibles, you are safe-guarding the future of these species. You are guaranteeing we will have a wide variety of genetic diversity in our future and not just the current “top growers.”

The final reason to collect seeds is to trade them. You may have 100s of Cleome seeds and another gardener has 100s of Poppy seeds. Why not trade a few hundred with each other? Again, you are getting new plants for free or close to it. Seed trading is a whole world unto itself. There are online groups, pen pal lists, and clubs for seed swapping.

Seed collecting is easy. Just wait until the end of the growing season when your current flowers form seedpods. Check on them every few days. They are ready when the pods are dry, brittle, and just ready to open. Don’t wait too late or they’ll break open on their own and cast their seeds to the wind. Pick a day with little breeze and no rain. Go out in mid-morning, after the sun has dried out the air and dewdrops from the leaves. Take a piece of paper and put it under the seed heads then shake them gently. Be sure the seeds are thoroughly dry before you put them in tightly closed jars or zipper-closed baggies. Label them right away and store them in a cool, dark, and dry place.

That last step is the most important. Label them with the date and variety. Be specific as possible. Next spring you’ll be very glad you did – as many seeds look alike. The date is important as you will want to use up your seeds the next growing season or two.

A side note on seed collecting: not all plants can be propagated from seed. Many plants that you buy are hybrids or sterile. If you have hybrid flowers and vegetables, they may produce seeds. However, the seeds will often not produce offspring that is “true” to the parent plants. In other words, the seeds from hybrids are often a different variety than the plant you originally purchased and they are often inferior in quality.

A simple way to get started is to collect seeds from your common annual flowers that open-pollinate: zinnias, marigolds, forget-me-nots, four-o-clocks, cosmos, cleome, and sunflowers. Then, as your gardening skills grow, move on to perennials and biennials.

So take a few minutes this harvest season to collect those plant seeds and you’ll be all set next spring for a bountiful crop of new blooms.

  1. I offered a seed donation program for about 10 years of OP, heirloom, organic seeds all across Georgia in hope of teach schools and community gardens to start saving seeds. I got no response. so I shut it down. We do not have a seed lending library or real seed swap in the Atlanta area. I would love to start one. I am a 501(c)(3).
