Storing flower seeds in a plastic bag is a viable option, but it depends on the type of seed, the environment, and the duration of storage. Plastic bags are suitable for short to medium-term storage, and thicker freezer bags with stronger seals are preferable to prevent air penetration and moisture accumulation. Seeds should be kept in a cool, dry, and dark location, away from direct sunlight, to maintain their viability and prevent unwanted decay and loss of germination rates.

What You'll Learn
Plastic bags are good for short to medium-term storage
Plastic bags are a good option for storing flower seeds in the short to medium term. They are particularly useful for storing small seed quantities. When using plastic bags, it is important to remove as much air as possible before sealing the bag. Freezer bags are preferable to regular storage bags, as they are made of thicker material and have better zipper seals.
To avoid unwanted decay and loss in germination rates, it is important to keep flower seeds dry during storage. Plastic bags can be useful in this regard, as they can help to protect seeds from unwanted moisture. If humidity or moisture is a problem, placing silica gel packets inside the plastic bag can help to manage excess moisture. However, it is worth noting that some sources recommend against using plastic bags in humid environments.
Light is another important factor to consider when storing flower seeds, as it can spur sprouting and natural decay. Therefore, plastic bags should be stored in a dark, dry place, such as inside an opaque container or cabinet. It is also important to keep plastic bags out of direct sunlight, as they can trap sunlight and potentially damage the seeds.
By following these guidelines, gardeners can effectively use plastic bags for short to medium-term storage of flower seeds. However, for long-term storage, other options such as airtight containers or mason jars may be more suitable.

Freezer bags are better than Ziplock bags
Flower seeds can be stored in plastic bags, paper envelopes, or sealed containers. When storing seeds, it is important to consider the storage environment, the type of seed, and the duration of storage. While Ziplock bags can be used for seed storage, freezer bags offer several advantages that make them a better choice.
Firstly, freezer bags are made of thicker material, which provides enhanced protection for the seeds. The thicker plastic of freezer bags reduces the occurrence of tears and punctures, ensuring that the seeds remain securely enclosed. This feature is especially beneficial if you plan to store the seeds for an extended period or in harsh conditions.
Secondly, freezer bags are specifically designed to prevent freezer burn, a common issue when storing items in the freezer. Freezer burn occurs due to the evaporation of moisture from the food to the outside air, and the thicker plastic of freezer bags helps deter this process. By using freezer bags, you can maintain the quality and freshness of your seeds over a longer period.
Additionally, freezer bags often feature double zipper strength, which provides a more secure seal compared to regular Ziplock bags. This secure seal helps prevent air and moisture penetration, maintaining the integrity of the seeds. The improved zipper also ensures that the seeds do not spill or leak, especially when storing fine and delicate seeds.
Furthermore, freezer bags are generally more durable and can withstand the challenges of long-term storage. They are designed to protect against very low temperatures and harsh environments. This durability means that freezer bags are less likely to fail or degrade over time, ensuring the seeds remain safely stored until you need them.
While Ziplock bags may be adequate for short-term seed storage, freezer bags offer superior protection, durability, and longevity. By choosing freezer bags, you can have peace of mind knowing that your flower seeds are well-protected and preserved for future use.

Store in a cool, dry, dark place
Keeping flower seeds in a cool, dry, dark place is essential for their preservation. The ideal temperature range for storing seeds is between 4° Celsius and 21° Celsius (40° Fahrenheit and 70° Fahrenheit). Avoid exposing seeds to temperatures above 90° Fahrenheit, as this will significantly reduce their viability.
Seeds should be kept in a dry location away from direct sunlight. Light can accelerate germination and reduce viability. Plastic bags are suitable for storing seeds, but they should not be placed in direct sunlight as they trap sunlight, which can harm the seeds. It is also important to ensure that no moisture is trapped inside the bag when sealing it. Press out as much air as possible and make sure the bag is completely closed to prevent moisture from getting inside.
Seeds can be stored in various containers, such as paper envelopes, Mason jars, seed storage boxes, or zip-closure bags. When using paper envelopes, it is recommended to place them inside an airtight jar or container to protect them from moisture and humidity.
Some recommended storage locations include closets, pantries, kitchen cabinets, office drawers, basements, garages, and refrigerators. These locations provide consistent temperatures and protect seeds from direct sunlight and moisture.

Avoid high humidity
When storing flower seeds, it is important to avoid high humidity as it can negatively impact seed viability and seedling vigour. Relative humidity below 60% is recommended for optimal seed storage. To achieve this, there are several measures you can take:
Firstly, choose an appropriate storage location. Avoid storing seeds in areas with high humidity, such as sheds or garages, especially during the summer months when humidity levels tend to be higher. Instead, opt for a cool, dry location with stable temperatures.
Maintain temperature control by ensuring that the storage area remains within the recommended temperature range of 35°F to 40°F (2°C to 4°C). Fluctuations in temperature can be detrimental to seeds, so consistency is key. Avoid placing seeds near heat sources or in direct sunlight, both during storage and transportation.
Use sealed, moisture-proof containers to store your seeds. This helps to maintain low humidity levels and prevent moisture buildup. If using a refrigerator for storage, which can extend the life of your seeds, ensure that the seeds are in sealed containers to mitigate the typically high humidity levels found in refrigerators.
Additionally, before storing your seeds, ensure that they are thoroughly dry. This initial dryness will help maintain low humidity levels during storage. By following these guidelines, you can effectively avoid high humidity when storing flower seeds, thereby increasing their longevity and viability for future planting.

Plastic bags should be kept out of direct sunlight
Plastic bags can be used to store flower seeds. However, it is important to keep them out of direct sunlight. Sunlight can speed up germination and cause a loss of viability. If you are using a plastic bag, it is recommended to use a freezer bag with a good zipper seal, as these are made of thicker material. To further protect the seeds, you can place the plastic bag inside an airtight container such as a jar or recipe card box, and store it in a cool, dry, and dark location.
It is worth noting that plastic bags are not the best option for long-term seed storage. They are more suitable for short to medium-term storage. For long-term storage, consider using moisture-proof containers such as sealed cans or jars, and store them in a refrigerator or deep freezer.
Additionally, the longevity of seeds depends on various factors such as the storage environment, the seed type, and the intended storage period. Some seeds have a naturally shorter lifespan than others. For example, parsnip seeds only have about a 50% chance of sprouting after being stored for a year.
To extend the life of your seeds, it is crucial to reduce humidity. Relative humidity below 60% is ideal for seed storage. Avoid storing seeds in humid environments, as this can negatively impact their viability. Exposure to temperatures above 90 degrees Fahrenheit will also decrease the likelihood of future germination.
In summary, while plastic bags can be used for storing flower seeds, they should be kept out of direct sunlight and used in conjunction with airtight containers for optimal seed longevity.
