Reusing Seed Envelopes - What To Do With Old Seed Packets

Seed holders: Simply reuse seed packets for their intended use. If you collect seeds at the end of the growing season, save those packets for an easy way to keep them separate and identified. You can seal the packets into sandwich bags or plastic containers for storage.

Can you use expired seed packets?

So, will expired seeds grow? Yes. Plants grown from expired seed packets will grow to produce healthy and fruitful harvests, just as their younger counterparts.

How do you store unused seed packets?

If you're creating your own seed bank, store seeds in their original packages if possible, or in a labeled envelope (include the date) in a jar or a cookie tin with a tight-fitting lid, protected from light and moisture. Cool temperatures are recommended.

What can I do with unused seeds?

Never leave leftover seed packets outside in the garden or garage or in an unheated outdoor shed, because high humidity and dampness will ruin them. A sealed mason jar or freezer-weight ziplock bag is an ideal storage container. Keep seeds dry and in your coolest room. Plan to use them the next season.

How long are flower seed packets good for?

To keep the seeds cool (ideally, below 50 degrees), some people store them in a jar in their refrigerator or freezer. Seeds in good condition and stored properly will last at least one year and, depending on the plant, may last two to five years.

Will 20 year old seeds grow?

There is a good chance that those old seed packets will have a high percentage of seeds that will germinate just fine. Most seeds, though not all, will keep for at least three years while maintaining a decent percentage of germination. And even a group of very old seeds may have 10 or 20 percent that still sprouts.

Is it worth planting out-of-date seeds?

I'm not necessarily recommending out-of-date seeds as being better than, or even as good as, fresh seed. Old seed often has sporadic or very slow germination, and sometimes the plants which do grow are a bit weak and wobbly. But there are many good reasons to keep hold of those old packets.

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 moisture trapped will cause the seed to mold and ruin the sample. The bag should always be kept in a dry place.

How do you store seed packets long term?

For long-term storage—or if you don't have a basement or cupboard with consistent temperatures—consider freezing (completely dry) seeds in a glass jar. The refrigerator is second-best, since temperatures aren't as consistent there. This part is so important for keeping the quality of seeds!

How do you store seeds for years?

Store seeds in tightly sealed glass containers. You can store different kinds of seeds, each in individual paper packets, together in a large container. Keep seeds dry and cool. A temperature between 32° and 41°F is ideal, so your refrigerator can be a good place to store seeds.

How do you know if vegetable seeds are still good?

There are two easy tests you can take to check to see if there is life left in your old seeds. Water test: Take your seeds and put them in a container of water. Let them sit for about 15 minutes. Then if the seeds sink, they are still viable; if they float, they most likely will not sprout.

How do I preserve seeds for next year?

A dark closet in a cooler part of the house or a dry, cool basement are both good spaces to store seeds for a year or two. Once properly dried, seeds can also be sealed in airtight containers and stored in the refrigerator or freezer for several years. The seeds of some crops are naturally longer lived.

When should I buy seeds for next year?

Therefore, you could (and probably should) start buying your seeds around January and February! Buying your seeds sooner than that wouldn't hurt either. Keep in mind that some plants will not transplant well and should not be started indoors.

What is the importance of shelf life in seeds?

Seeds more than a year or two old may not germinate well or at all, particularly if they have not been stored properly. Some seeds, even after a year of proper storage, may not produce the number of plants you expect or need.

How long do seeds last in freezer?

Longer Term Storage

Only seeds are stored in the freezer and it is opened only a couple of times a year, so temperature swings are minimized. The freezer is usually run at about -15F. Most seeds will last a minimum of 5 years with certain hardy varieties lasting 20+ years!

What seed takes the longest to germinate?

A date palm seed some 2000 years old – preserved by nothing more than storage in hot and dry conditions – has germinated, making it the oldest seed in the world to do so. The ancient seed was found along with several others in the 1960s in the Masada fortress on the edge of the Dead Sea in Israel.

Do heirloom seeds expire?

Depending on the type of seed and its quality, you may be able to store them and use them next year or the year after. In fact, some seeds, if properly stored, can be viable even after ten years.

How do seeds die?

Seeds Freeze

Planting too early or when hard frosts come through after planting can result in the seeds freezing and dying. Sometimes this is also caused by improper seed storage in the off season.
