Grass seed should last between 10-18 months from the testing date, without a significant decrease in the germination rate. Grass seed must be stored in a cool, dry place away from heat, moisture, and direct sunlight.
It is best to store the seeds in an airtight container with a tight fitting lid. Do not store seed in your refrigerator or freezer. If you must store your seeds, store them in plastic bags or containers with tight-fitting lids.

Can I store unused grass seed?
Saving grass seed from one year to the next isn’t usually recommended, but it’s possible as long as you have reasonable expectations for how that seed will perform the following season. The longer the seeds are allowed to sit in the ground, the less viability they have. The best way to determine how long grass seeds will last is to look at how well they perform in your area.
If you live in an area with a lot of tall grass, you may want to wait a few years to see if the grass will grow back to its former glory. On the other hand, if your grass is short-lived, it may be a good idea to replant your seedlings as soon as possible.
How can you tell if old grass seed is still good?
Put your seeds in a container of water for a water test. Allow them to sit for 15 minutes. If the seeds sink, they are still viable, but if they float, they are not likely to grow.
Will 10 year old grass seed still germinate?
After the first few years of storage, grass seed germination rates tend to decrease. It is thought that a 10 year old bag of seed would see around 1 in 5 seeds start to grow. Well, if you want to get the most out of your seeds, it’s best to store them in a cool, dark place, away from direct sunlight.
If you live in an area that gets a lot of sunlight, you may be able to grow your seed indoors, but you’ll need to invest in some sort of light-emitting diodes (LEDs) in order to do so. LED’s are much more energy efficient than incandescent bulbs, so they’re a great choice for growing seeds indoors. They’re also much less expensive than CFLs, which are more commonly used for indoor growing.

Is grass seed still good after 2 years?
If stored in a cool, dry place, grass seed can last for two to three years, but you may not get the same results as you would when planting fresh seed. You have to use more seed than normal because the percentage of seeds that will be able to grow decreases as the seed ages.
Grass seed is a good source of nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. It also contains trace amounts of iron, copper, manganese, zinc, chromium, molybdenum, boron, nickel, cobalt, selenium and copper. Grass seed also has a high protein content, making it an excellent food source for poultry, cattle, sheep, goats, horses, swine and poultry.
How Long Can grass seed be stored in a garage?
Grass seed can be kept for two to three years if it’s properly stored. After storage, the rate of germination tends to decrease. For each subsequent year you store the seed, you should expect the initial germination rate to decrease by 10 to 20 percent. The best way to store your lawn seed is to keep it in a cool, dry place away from direct sunlight.
If you are storing your seed indoors, it is recommended that you keep the temperature between 70 and 80 degrees Fahrenheit (21 to 25 degrees Celsius). If your seeds are stored outdoors, they should be kept at a temperature of 60 to 70 degrees F (16 to 21 degrees C) and a relative humidity of 75 to 80 percent.
Can grass seed be stored in garage in winter?
Keep your seed from freezing by storing it in your cool dry basement (not your unheated garage or shed). Place the bags in a plastic tub or metal container to prevent mice from getting to the seeds.
Can I leave grass seed in garage over winter?
Storage conditions do have a major influence of the long-term viability of stored seed. Storing your seed outside in a shed, or garage is not ideal due to the exposure to heat and humidity. If you want to extend your germination time, try storing your seed indoors in a dry area.
Are 20 year old seeds still good?
The truth is that the seeds don’t go away. They lose their viability if they are not properly stored. If you keep the seeds in a cool, dry place, they will keep for decades and will grow when planted. The best way to store your seeds is to keep them in an airtight container with a tight fitting lid. This will prevent the seeds from drying out, which can lead to mold and fungus growth.
You can also store seeds in the refrigerator for up to a year, but keep in mind that the longer you store them, the more likely it is that they will rot. If you are storing seeds for a long period of time, you may want to consider storing them at room temperature instead of in your refrigerator.
Can a seed be too old?
The answer is, yes, seeds will eventually go bad and no longer germinate, but it can take quite a long time. The first thing you need to do is to check the germination rate of your seed packet. If you see that your packet is not growing, then it is probably time to throw it out and start over. Another thing to look out for is the amount of time it takes for the seed to reach maturity.
This can be measured in days, weeks, months or even years, depending on what type of seed you are using. For example, if you use a seed that has been in the ground for a year and a half, it will take a lot longer for it to mature than if it was planted in a couple of days.
