How do I store seed packets?

store seed packet correctly

It is important to store seed packets properly to maintain their viability and ensure successful germination when you’re ready to plant them. Here are some guidelines for storing seed packets:

Cool and dry location

Seeds should be stored in a cool, dry place. Moisture and heat can reduce their viability. Aim to store seed packets at temperatures between 32°F (0°C) and 50°F (10°C). Avoid storing seeds in areas with high humidity, such as basements or bathrooms.

Make sure your seed storage container has a tight fitting lid

Place the seed packets in a containers with a tight lid to protect them from moisture and pests. Make sure the containers are clean and dry before use.

Get Labelling when you store seed packets

If you have harvested seeds, Clearly label each container with the name of the seeds, the date they were purchased or collected, and any other relevant information, such as the plant variety or special instructions. Our Chester & Cooke seed harvest envelopes are great for collecting seeds. Storing seeds in paper envelopes is a good options for the seeds health.

Store Seed Packets in the Dark

Store the seed storage containers in a dark place. Exposure to light can reduce seed viability for some plant varieties. So using Glass jars isn’t a good idea.


Organise your seed packets when storing them

If you have multiple seed packets, consider organising them by plant type or sowing season. This will make it easier to find the seeds you need when the time comes. Using our Seed Divider cards in your Seed storage container is really helpful, you can either organise by date of sowing colour or any other system you may choose. From £7 for a set of 3 (which can be purchased here) for the main section of our box or £9 for the front section (which can be purchased here) . These are a nice little treat for any gardening friend.

Store seed packets and organise them into date or type.

Moisture control

To further protect seeds from moisture, you can add desiccant packets or silica gel sachets to the containers. These absorb moisture and help maintain seed quality. – we provide these for free in our Chester & Cooke seed box.

Monitoring your seed packets regularly

Check your stored seeds periodically to ensure they remain dry and free from pests or mold. Remove any damaged or rotten seeds to prevent contamination.


Refrigeration or freezing (optional)

For long-term storage, some seeds benefit from refrigeration or freezing. However, not all seeds tolerate cold temperatures, so it’s important to research the specific requirements for each plant variety. If you choose this method, place the seed packets in airtight bags or containers to prevent moisture condensation when removing them from the fridge or freezer.

Remember that seed viability can decrease over time, even with proper storage. It’s a good idea to periodically test the germination rate of older seeds before relying on them for a large planting.

I hope you have learnt how to store your seed packets in the best way. I have carefully designed my seed box so that it stores seed packets in the most viable way and is large enough for a professional gardeners seed collection. You can shop my Chester & Cooke gardening range HERE.
