There are many factors that influence your heirloom seed selection decision-making process, including:

  • Purpose of use
  • Growing climate
  • Garden area
  • Your own tastes
  • Your gardening skills

Most heirloom vegetables have been developed for variety. For example, some sweet potato varieties were developed to bring a sweeter taste, several produce larger-size tubers, and others can stay fresh for longer than supermarket hybrids.

You should determine the soil type of your garden, the type of climate, how much time you’re willing to take care of them, and your knowledge about gardening.

Next, list out the heirloom vegetables that you want to grow, then learn about their growth requirements to find out the ones suited to you.

Choose Heirloom Seeds

On the seed packet, look for either the abbreviation “OP” – which means Open Pollinated – or the term “heirloom”.

These seeds are not necessarily heirlooms because you can save your own heirloom seeds from normal breeds as long as they are purebreds.

Avoid choosing:

  • GMO seeds – which are bred in a lab using gene splicing or other modern biotechnology techniques, and they can’t produce seeds

  • Any seed packet that has the abbreviation “F1” – which means the first generation that was deliberately crossed by humans from two different varieties of plants. And, you can’t save seeds from these hybrid plants.

Harvest And Save Seeds

You must let the fruit/tuber ripen on the plant before plucking or digging in for the seeds. The sweet point of harvesting seeds varies between species.

Some vegetables have the point of harvesting the seeds coinciding with the point they're ready to be consumed, such as melons and peppers.

How To Save Heirloom Seeds

Seeds after harvesting should be dried out before being stored. There are many ways to dry seeds, such as using dedicated equipment, sunlight, or a fan.

Seeds should be laid in a thin layer on a dry and clean surface. You can line a layer of dry paper plate or newspaper underneath to speed up the process.

Choose a dry and air-ventilated spot to dry your heirloom vegetable seeds.

After drying, seeds should be stored in sealable plastic bags or air-tight containers in cool temperature conditions (in a freezer or a fridge). This method is for long-term storage.

Or, if you intend to store them for a short time before seedling, keep the seeds in envelopes, glass jars, or plastic bags and store them in room temperature condition.

With a small-size garden, it is highly recommended to grow just one variety at a time.

If you still want to grow more varieties of a species, plant them separately in an enclosure greenhouse to isolate your plants from outside aid. Then, hand pollinates. If you don’t have a greenhouse, bag individual flowers and hand pollinate.

Another solution is to plant each variety in a separate screened cage and hand pollinate.
