Quick answer

For a backyard food garden, buy open-pollinated or heirloom seed if you want to save seed and replant; UMN Extension says these set seed that grows plants very similar to the parent, while seed saved from hybrids does not. Almost all home garden vegetable seed is non-GMO anyway: FDA lists only a few GMO fresh crops, such as some potatoes, summer squash, apples and papayas. Store seeds dry and cool, ideally 32 to 41°F, in sealed glass jars.

Heirloom, open-pollinated and hybrid in plain terms

Type	What UMN Extension says	Save seed?
Open-pollinated	Pollinated by the same variety, sets seed that grows into plants very similar to the parent	Yes
Heirloom	Open-pollinated varieties passed down through generations; open-pollinated can also include newer selections	Yes
Hybrid	A cross between two varieties, sometimes with outstanding vigor, disease resistance and productivity; costs more to produce	Seed is viable, but offspring are unpredictable

UMN names examples: 'Brandywine', 'San Marzano' and 'Big Rainbow' tomatoes and 'California Wonder' peppers are open-pollinated; 'Big Boy', 'Beefmaster' and 'Early Girl' tomatoes are hybrids.

What non-GMO means on a seed packet

• Few GMO garden crops exist: FDA lists potatoes, summer squash, apples, papayas and pink pineapples as the few fresh produce items available in GMO varieties.
• The big GMO crops are farm crops: soybeans, corn, sugar beets, canola and cotton; FDA says GMO varieties made up 92% of corn planted in 2020, mostly for animal feed and ingredients.
• So the label adds little: a packet of heirloom tomato or bean seed was never going to be GMO. Look for open-pollinated, heirloom or hybrid, which tell you more about how the plant grows and whether you can save its seed.
• Non-GMO is not organic: organic is a separate certification; neither label says anything about germination or variety fit for your climate.

Best crops for saving your own seed

• Easiest: UMN lists tomatoes, peppers, beans and peas, which have self-pollinating flowers and seeds needing little or no treatment before storage.
• Harder: biennials like carrots and beets need two growing seasons to set seed.
• Cross-pollinators: corn and vine crops cross easily; UMN notes popcorn can pollinate sweet corn in a nearby garden on a windy day, and insects cross cucumbers, melons, squash, pumpkins and gourds.
• Pick parents carefully: save seed only from the most vigorous plants with the best-tasting fruit, and never from weak or off-type plants.

Harvesting seed, crop by crop

1. Tomatoes: scoop seeds and gel into a jar with water, swirl twice a day, and after the mixture ferments and seeds sink, within about five days, rinse and dry on paper towels.
2. Peppers: leave some fruit on the plant until fully ripe and wrinkling, then remove and dry the seeds.
3. Beans and peas: let pods dry on the plant until seeds rattle, which UMN says can take a month past eating stage, then dry the pods indoors at least two weeks before shelling.

Storing seeds so they last

• Container: UMN recommends tightly sealed glass containers; individual paper packets can go inside one large jar.
• Temperature: 32 to 41°F is ideal, so a refrigerator works.
• Dry: add a small amount of silica gel desiccant, or one to two tablespoons of fresh powdered milk wrapped in tissue, which UMN says absorbs moisture for about six months.
• Label: write the variety and year on every packet so you plant the oldest first.
• Clean seed: UMN warns that tomato bacterial canker can arrive on infected seed; buy from a reputable supplier and save seed only from healthy plants.

A seed supply for food security

A seed collection is a long-term food plan, not a short-term emergency ration: it takes a season to produce food. Start with crops your family eats, in a mix of cool-season greens and roots and warm-season tomatoes, peppers and squash. Plant some every year so you learn your soil and keep fresh seed in rotation.

Questions people ask

What are the best garden seeds for a survival garden?

Open-pollinated or heirloom seed of crops you eat, so you can save seed; UMN lists tomatoes, peppers, beans and peas as the easiest to save.

Are non-GMO vegetable seeds different from regular seeds?

Usually not; FDA lists only a few GMO fresh crops, such as some potatoes, summer squash, apples and papayas.

Can I save seeds from hybrid vegetables?

They produce viable seed, but UMN says the plants will not match the hybrid parent.

How should I store garden seeds?

In sealed glass jars, dry and cool; UMN says 32 to 41°F is ideal, with silica gel to absorb moisture.
