Storing seeds in plastic bags is a common practice, but there are some important considerations to ensure their longevity. Firstly, plastic bags should never be placed in direct sunlight as this can quickly kill or damage the seeds. Plastic bags are effective for short to medium-term storage if they are properly sealed to prevent moisture absorption and stored in a cool, dry, and dark location. For long-term storage, it is recommended to use airtight containers such as Mason jars or vacuum-sealed mylar bags, especially for tiny seeds that require more protection from moisture and pests. Proper seed storage methods, including the use of plastic bags, can help extend the lifespan of seeds beyond their sell-by date, saving money and ensuring the availability of favourite varieties.
| Characteristics | Values |
|---|---|
| Storage | Plastic bags are good for short to medium-term storage. |
| Containers | Seeds should be stored in airtight containers to protect them from unwanted moisture, light, and pests. |
| Plastic Bags vs Paper Envelopes | Paper envelopes are good for short-term storage but are best enclosed in an airtight jar with a desiccant. Plastic bags trap sunlight, so they should never be placed in direct sunlight. |
| Moisture | Plastic bags are good for storing seeds in a humid environment as they can be rolled up to squeeze out air before closing. Plastic bags should be stored in a cool, dry location. |
| Temperature | Seeds should be stored at 60-65°F (16-18°C) for collecting seeds for a year. For long-term storage, the temperature should be 40°F (4°C) or lower. |
| Seed Longevity | Proper storage can allow seeds to be used successfully for several years beyond their "sell by" date. Fresh seeds generally exhibit higher vigor compared to old seeds, which can suffer from reduced germination rates. |

Plastic bags are good for short-term storage
Plastic bags are good for the short-term storage of seeds. They are an effective way of protecting seeds from the elements when mailing them to others. However, if used for storage, they should be placed in a jar or another container. Plastic bags should never be placed in direct sunlight as this can kill the seeds.
When using plastic bags to store seeds, it is important to remove as much air as possible from the bag before sealing it. Plastic bags are useful for storing seeds in the freezer, as they take up less space. They can also be used to store seeds in a binder, along with baseball card pages, to keep them organised in a small space.
It is important to note that seeds should be properly dried before being placed in any airtight container, including plastic bags. Seeds should be stored in a cool, dry location, ideally at 60-65°F (16-18°C) for up to a year. If using plastic bags, it is best to place them inside another container, such as a jar or Tupperware, to protect them from light and pests.

Paper envelopes are better for short-term storage
Plastic bags are not ideal for storing seeds. They trap sunlight, so they should never be placed in direct sunlight. Even a short period of exposure can quickly kill or injure the enclosed seeds.
If you are using plastic bags, it is important to remove as much air as possible before sealing. You can also place the envelopes inside a Mason jar or another type of glass container. These containers should be stored in a dark, dry place, such as inside a cabinet or beneath other items that block out the light.
Overall, while plastic bags can be used for seed storage in the short to medium term, paper envelopes are a better option for short-term storage, especially when combined with a jar or box for added protection from light and moisture.

Plastic bags should not be placed in direct sunlight
Plastic bags can be used to store seeds, but there are several factors to consider to ensure the seeds remain viable. Firstly, it is important to note that plastic bags should not be placed in direct sunlight. Sunlight can spur sprouting and cause the natural decay of organic matter, resulting in the spoilage of seeds. Even a short period of exposure to direct sunlight can quickly kill or damage the enclosed seeds. Therefore, it is recommended to store plastic bags containing seeds in a cool, dark location.
To further protect seeds stored in plastic bags from sunlight, they can be placed inside opaque containers such as Tupperware or metal containers. Additionally, it is essential to remove as much air as possible from the plastic bags before sealing them. This helps to extend the lifespan of the seeds by reducing the risk of condensation and moisture buildup. Condensation can occur due to temperature fluctuations, which can damage seeds if the moisture freezes. Therefore, maintaining a cool and dry storage environment is crucial.
The type of seed and the intended storage duration also play a role in the suitability of plastic bags for seed storage. Plastic bags are ideal for short to medium-term storage. For long-term storage, consider using paper envelopes inside Mason jars or airtight boxes. Paper envelopes are more breathable than plastic bags, reducing the risk of moisture buildup. However, they are more susceptible to humidity and should be used in low-humidity environments.
Proper seed storage is essential to maintain seed health and vigour. Fresh seeds generally exhibit higher vigour, and improper storage can lead to reduced germination rates and increased disease susceptibility. By following the recommended storage practices, such as keeping seeds in a cool, dry, and dark location, you can ensure the longevity and viability of your seeds.

Seeds should be stored in a cool, dry location
Plastic bags can be used for storing seeds, but they are not ideal for long-term storage. Zippered plastic bags are good for short to medium-term storage. However, it is important to note that plastic bags should never be placed in direct sunlight as they trap sunlight, which can quickly kill or damage the seeds inside. If you do use plastic bags, it is recommended to roll them up tightly to remove as much air as possible before sealing.
Basements, closets, pantries, kitchen cabinets, office drawers, and even under the bed are all suitable storage locations that typically maintain a consistent temperature and avoid direct sunlight. It is important to avoid areas near air vents, as these can cause significant temperature fluctuations.
In addition to maintaining a cool temperature, it is crucial to ensure that the storage location is dry. Moisture is one of the critical factors influencing seed longevity. The drier the seeds are, the longer they will remain viable. To achieve this, some individuals use airtight containers, such as Mason jars, metal containers, or moisture-proof foil bags, to prevent moisture from reaching the seeds. Desiccants, such as silica gel packets or dry rice, can also be placed inside the storage container to absorb any excess moisture.
By storing seeds in a cool, dry location, you can extend their viability and improve the chances of successful germination when the time comes to plant them.

Plastic bags are useful for mailing seeds
When using plastic bags for seed storage, it is recommended to place them inside another container such as a jar or a box. Plastic bags are useful for storing seeds as they are sealable and can be rolled up to remove as much air as possible, helping to keep the seeds dry. This is important as moisture can cause seeds to lose some dormancy and can damage them if it freezes.
One way to ensure seeds remain dry is to use desiccants such as dry white rice or silica gel packets. These can be placed inside the plastic bags to absorb excess moisture. It is also recommended to store seeds in a cool location, with a temperature of around 60-65°F (16-18°C) for seeds being collected for a year, and 40°F (4°C) or lower for long-term storage.
Plastic bags are a convenient option for mailing and storing seeds, but it is important to take precautions to protect the seeds from sunlight, moisture, and extreme temperatures.
