Save the seeds from some of your garden vegetables to replant again! Here's our seed-saving guide for beginners.

Below is a general rundown of how to gather and treat the most commonly-saved garden seeds. (If you haven't read our primer on seeds, you may wish to review the article, "Start Saving Those Vegetable Seeds" first.)

Tomatoes and Cucumbers

Because tomatoes and cucumbers have seeds that are coated with a gel, the first step is to remove it by fermentation. The process smells bad, however, so don't do it in an enclosed room in the house. Follow these steps:

  1. Squeeze or spoon the seed mass into a waterproof container (glass, jar, plastic, or deli container).
  2. Add enough water to equal the volume of the seed mass, and put the container in a warm spot out of direct sunlight.
  3. Stir the contents at least once a day.
  4. In a couple of days, the viable seeds will sink to the bottom and bad seeds and debris and white mold will float to the surface.
  5. Wait five days for all the good seeds to drop, then rinse away the gunk at the top.
  6. Wash the seeds in several changes of water, and lay them out in a single layer on a glass or plastic plate or screen.
  7. Put the plate in a warm place until the seeds are fully dry, which can take several weeks.

Peppers

  1. Cut peppers open to find the seeds in a mass on the central stem.
  2. Brush them off the stem onto a plate or screen.
  3. Put seeds aside to dry.

Squashes

  1. When squashes are ready, break them open and remove the seeds.
  2. Hold the seeds under running water, rubbing them between your fingers to remove any stringy material and membrane.
  3. Then lay them out on a plate or screen to dry.

Melons

  1. For watermelons, simply rinse the seeds under running water to remove any traces of flesh or membrane. For cantaloupe and musk melon, seeds will have more fibers and membrane attached to them. Wash this off, rubbing the seeds between your fingers to remove as much as the debris as you can.
  2. Then put the seeds in a container of water, and the good seeds will sink to the bottom.
  3. Remove what comes to the top, give the good seeds another rinse, and dry them on a plate or screen.

Peas and Beans

  1. Pick the brown bods from the vines and remove the seeds, which will require about six weeks of air-drying. One way is to put them in loosely woven baskets and stir them once a day.
  2. If frost or other inclement weather threatens legumes that are ripe but not dry, pull up the vines by the roots, and hang the plants upside down in a warm area, such as your basement or barn. The pods will draw energy from the plants for another few days, which will increase the seed viability.

Other Pods

Radishes, lettuce, and Chinese greens also produce seeds in pods after the plant has flowered. With these vegetables, too, it is best to let the pods dry on the plant.

These plants, however, tend to dry from the bottom up, a few pods at a time. The dry ones are prone to shattering and spreading their seed all over the ground, so either bag the seed heads—literally putting a paper bag tied at the base over the plants to capture the seeds—or pick the dry pods on a daily basis.  Old nylons or row-cover materials work well for bagging, because you can see what's going on with the pant.

Storage

Once your seeds are completely dry, they can be stored in any suitable containers and kept in a cool, dry area.

  • For large seeds, such as beans, you can recycle the cardboard canisters that certain snack foods come in.
  • For small seeds, such as pepper and tomatoes, washed-out pill bottles work well.

Seeds will remain viable for up to 15 years, depending on type. You can extend their viability by freezing them, especially if you have a zero-degree freezer. Properly dried and frozen seeds will remain viable for at least 40 years!

Correct me if I'm wrong, but

Correct me if I'm wrong, but I don't think this works for most garden veggies because they are probably hybrids. It's like trying to breed mules. One more reason to plant heirloom varieties.

Correct, save seeds only from open-pollinated or heirloom varieties, never from hybrids (which are very common from local garden stores). See more here:
