Did You Know?
1. In order to save corn seeds, it is important to choose heirloom or open-pollinated varieties, as hybrid corn seeds do not reliably produce the same quality or characteristics in the next generation.
2. The “Three Sisters” planting technique, used by Native American tribes for centuries, involves growing corn, beans, and squash together in the same plot. The corn provides a natural structure for the beans to climb, while the beans fix nitrogen in the soil, benefiting the corn, and the squash acts as a natural groundcover to suppress weeds.
3. Corn seeds can remain viable for up to five years if stored in a cool, dry place. However, the germination rate might decrease over time, so it’s a good practice to test a sample of the seeds each year to ensure viability.
4. Contrary to popular belief, corn, as we know it today, was not naturally occurring in the wild. It was selectively bred by indigenous peoples in Mesoamerica thousands of years ago from a humble grass called teosinte.
5. To save corn seeds, it is crucial to select the healthiest, most vigorous cobs for seed collection. It is recommended to choose cobs that have fully matured on the plant and show no signs of disease or insect damage.
Importance Of Choosing Open-Pollinated Corn Varieties
Corn is a popular crop for beginners and offers an excellent opportunity for seed saving. To ensure true reproduction, it is crucial to choose open-pollinated corn varieties. These varieties, such as heirlooms, allow for natural pollination by wind, insects, or other environmental factors. Hybrids, on the other hand, which are crossbreeds of different corn varieties, are not suitable for seed saving as their offspring will not remain true to the parent plant.
By selecting open-pollinated corn varieties, gardeners can preserve the unique traits and characteristics of the specific variety. These traits may include taste, texture, color, or even resistance to certain pests or diseases. Preserving these traits not only helps maintain diversity in our food system but also empowers gardeners to develop their own unique strains over time.
Isolating Corn For Proper Seed Saving
Corn is primarily wind-pollinated, requiring careful isolation from other varieties to prevent unwanted cross-pollination. Cross-pollination happens when pollen from a different corn variety fertilizes the silks of the desired variety, leading to hybridization and loss of desired characteristics.
To avoid cross-pollination, it is recommended to create physical barriers or time isolation between different corn varieties. Physical barriers can be achieved by planting different corn varieties at a distance or using tall barriers like hedges or buildings to disrupt wind movement. Time isolation involves planting corn varieties that flower at different times, preventing overlapping during the critical pollination period.
Taking necessary precautions to isolate corn varieties maintains the purity and consistency of saved seeds.
Selecting The Best Plants For Seed Saving
When saving corn seeds, it is essential to select the best plants to improve variety characteristics and ensure the production of high-quality offspring. Look for plants that exhibit desirable traits such as:
- Good ear size
- Kernel color
- Disease resistance
- Overall vigor
Start by observing the corn plants throughout their growing season, noting any differences in growth, yield, or resilience. Pay attention to how well the plants resist common pests or withstand adverse weather conditions. By selecting the best plants with these desirable traits, gardeners can gradually improve the variety over time.
After identifying the best plants, mark them with colorful ribbons or other visual indicators. This step will help ensure that the seeds harvested come from the selected plants, contributing to the ongoing improvement of the corn variety in subsequent seasons.

Harvesting And Drying Methods For Corn Seeds
To save corn seeds, harvest them at the right time – when the corn reaches full maturity and has completely dried on the plant. Look for signs that indicate the corn is ready for harvesting, such as dried husks and kernels that are hard and dry to the touch.
Once harvested, corn seeds require further drying to prevent mold during storage. There are three common methods for drying corn seeds:
-
Pulling back the husks but not removing them: This method allows air circulation while protecting the kernels from pests. Hang the husk-exposed cobs in a dry, well-ventilated area.
-
Removing the husks entirely and hanging the cobs in mesh bags: This method exposes the entire cob surface to air, facilitating faster drying. Hang the mesh bags containing the corn cobs in a cool, dry area.
-
Laying the cobs out on a rack or screen: This method allows for maximum airflow around the cobs, promoting even drying. Place the drying rack or screen in a well-ventilated place away from direct sunlight.
Regardless of the chosen method, it is essential to shake the drying bags or turn the cobs on the rack every couple of days. This action ensures that all the cobs receive equal exposure to air, resulting in uniform drying of the seeds.
Maintaining Genetic Diversity In Saved Corn Seeds
Maintaining genetic diversity in saved corn seeds is crucial to provide resilience against diseases, pests, and climate extremes. To achieve this, it is recommended to save a minimum of 500 seeds from at least 10% of the corn plants in your garden. By selecting seeds from a diverse range of plants, you ensure that a wide range of genetic material is preserved.
Saving seeds from a sufficient number of plants helps prevent inbreeding depression—a decline in vigor and adaptability caused by limited genetic diversity. The more seeds saved from a larger population of corn plants, the greater the chances of retaining valuable traits and allowing for adaptation to different environmental conditions.

Storing And Preserving Corn Seeds For Future Planting
Once the corn seeds are fully dry and clean, they are ready for storage. Using airtight containers, such as Mason jars, will protect the seeds from moisture and pests, ensuring their viability for future planting.
It is crucial to store the seeds in a cool and dark location to maintain their quality. Excessive heat, light, and moisture can decrease seed viability. A cool basement, pantry, or refrigerator are suitable options for storing corn seeds.
Label each container with the corn variety name and the year of harvest. This information helps ensure that the seeds retain their identity, making it easier to select specific varieties for planting in the future.
By following these simple yet vital steps, gardeners can independently save and preserve corn seeds, contributing to a sustainable and diverse food system.
- Use airtight containers
- Store in a cool and dark location
- Label containers with variety name and harvest year.
