Modern appliances make the ancient practice of seed-saving simpler. Warm, light, moist and oxygen cause seeds to grow, but the opposite conditions prevent them from growing in the future. Vacuum sealing the seeds in a plastic bag and storing them in the freezer is a great way to preserve your seeds for years to come.

What is the best way to store seeds for long term?
Store seeds in tightly sealed glass containers. In a large container, you can store different kinds of seeds in individual paper packets. The seeds should be kept dry and cool. It’s a good idea to store your seeds in your refrigerator at a temperature between 32 and 41F.
If you don’t have a refrigerator, you can keep your seed packets in an airtight container in the refrigerator for up to two weeks. If you are storing seeds for a long period of time, such as a year or more, it is best to refrigerate the packets.
Do seeds need oxygen in storage?
This experiment confirmed that seeds can survive perfectly well without oxygen when they are in a dry state as respiration is not active under such conditions. Seeds do require oxygen when moist as they are then respiring. Research is ongoing to find out how much water is needed for seeds to survive in the dry air. Seeds can be stored for long periods of time in airtight containers.
They can also be kept at room temperature for up to a year. However, it is important to keep the temperature of the air in which the seeds are stored at a minimum of 20°C (68°F) to prevent the germination of germinated seedlings. This is because a seedling can only survive for a few days if it does not have access to oxygen.
Can you freeze seeds to preserve them?
Freezing seeds does not harm them, and can greatly extend their lifespan if done properly. All seed banks freeze their seeds for long term storage. A blast of warm humid air on frozen seeds can cause them to rot, which is a greater concern with freezing.
Frozen seeds should be stored in a cool, dark, dry place, away from direct sunlight. They should not be placed in the refrigerator or freezer for extended periods of time. Seeds should also be kept in airtight containers to prevent them from drying out.
Can I store seeds in Ziploc bags?
Seed should be kept in a paper bag or envelope. Never store seed in a plastic bag or air tight container. The sample will be ruined by the trapped moisture. The bag needs to be kept in a dark place. Do not store the bag in direct sunlight.
How do you store seeds for decades?
Place the envelope in a plastic zip bag and close it, squeezing out as much air as possible. You can vacuum seal them with a Food- saver. The seeds will not be disturbed if you put the bag in the back of the freezer. Your seed will last up to a year if you keep it in a cool place.
If you want to store your seeds for a longer period of time, you can place them in the refrigerator for about a week or two. This will keep them from drying out and will also help them to germinate.
Will 20 year old seeds germinate?
Even seeds that are thousands of years old can germinate. The older the seed, the less energy it has left in storage, and proper pre-treatment is essential. It’s difficult to grow seeds from annual plants because they aren’t often designed to last many years.
The answer depends on several factors, including how old the plant is, how long it’s been in the ground and how much sunlight it gets each day.
If a plant has been growing for a long time, it may not be able to grow new leaves or flowers, but it can still produce seeds, which can then be sown into the soil to produce new plants.
