How to Properly Store Corn Seeds for Future Planting Success

As gardening enthusiasts, it’s always a great feeling to harvest your own vegetables. But what do you do with the seeds of the plants that have grown? Well, if you’re planning on growing corn again next year, it’s important to store its seeds properly in order to ensure good germination rates.

Here are some steps and tips on how to store corn seeds for next year:

Harvesting Corn Seeds

First things first, you need to ensure that the corn is ready for harvesting. In general, this means waiting until the ears have fully matured and dried out on the stalk. You can check by peeling away a small part of the husk and examining its kernels – they should be hard and completely dry.

Once you’ve determined that your corn is ready for seed collection, cut down each ear carefully using pruning shears or scissors. Be sure to leave enough stem attached so that each ear can be hung up easily for drying.

Drying Corn Seeds

The most important step in storing any type of seed is making sure they are thoroughly dry before keeping them in storage containers. This prevents mold growth and ensures higher germination rates when planting season rolls around again.

To dry your harvested corn ears:

1. Cut off any remaining leaves from each ear.
2. Tie string or twine around each ear’s stem.
3. Hang them up somewhere airy where there won’t be any risk of getting wet or damaged (e.g., garage).
4. Wait until all kernels are completely dry – this may take several weeks depending on temperature/humidity levels in your area.

Shelling Corn Seeds

Once all ears have been dehydrated entirely, remove their kernels using one of two methods:

– Twist individual cobs gently while holding over a large container/bucket
– Rub multiple cobs together within a sack/pillowcase to loosen kernels

After all the kernels have been obtained, separate any that appear damaged or discolored. You can also use a strainer to sieve out smaller debris.

Storing Corn Seeds

Finally, it’s time to store your corn seeds in containers that will keep them safe until next year’s planting season. Here are some tips on how you can do this:

– Use airtight glass jars or thick plastic bags with zip locks.
– Label each container clearly so you know what type of seed is inside and when it was harvested.
– Store in a dark, cool place like a basement or cupboard (ideally around 40°F/4°C).
– Check every few months for signs of moisture damage/mold growth and discard any affected seeds.


To ensure maximum germination rates for growing corn next year, these steps should be followed carefully – harvesting mature ears at the right time, drying them thoroughly before shelling their kernels, and storing those seeds correctly in air-tight containers labeled by harvest date. This process may take some effort but is worthwhile for producing healthy crops over extended seasons. Happy seed saving!
