Some seeds can last for a couple of years, while others can last longer.
They don’t exactly expire but the germination rates can decline.
Here’s what to know when using seeds from previous seasons.
What Do The Dates On Seed Packets Mean?
And you’ll find more information on your seed packet than just a date.
Seeds with high germination rates may have been collected a few years prior.
“Many seeds can be sown after the date as long as they are stored properly.
Dates provide information when germination is highest, which provides a better success rate when sowing seeds.
for a better success rate when sowing seeds.
Why Do Seed Packets Have Dates?
Dates are included on seed packets to help consumers make informed decisions.
It’s also the law.
Seeds are regulated at the state and federal levels.
The Federal Seed Act regulates how seed packets are labeled and promoted across states.
State laws are often stricter than federal laws, too.
State laws can also require seed packets to include when germination tests were done.
“Most states follow a 12-month window for germination testing,” says Key.
“Every seed packet over 1 pound must list the germination rate and test date on the label.”
What Are the Factors That Affect Seed Viability?
Seed viability equates to a seed being able to produce a plant.
The quality of a seed when they are harvested plays an important role for seed viability and germination.
Seeds can be dried out or lighter in color.
The good news is there is a method to detect if seeds are likely to germinate.
“If very few seeds germinate, then viability is likely to be low as well.”
On average, seeds can be sown over several growing seasons.
You’ll need a paper towel, water and a receptacle or plastic bag.
Seed packets will state how long it takes for the seed to germinate.
“For instance, a tomato should germinate in 7 days at room temperature,” says Turner.
Once the seeds have germinated, count them.
“The ideal environment is cool and dry: around 3545F and 3545% humidity,” says Key.
Experts recommend an ideal place to store seeds in your home that might not be on your radarthe fridge.
“Storing seeds in an airtight ziplock bag in the refrigerator is a great option,” says Key.
ensure seeds are in an airtight container, especially when placing them in the refrigerator.
Moisture and warmer temperatures can create the ideal conditions for seeds to start germinating.
