How long does grass seed last?

Answer by  ebu (14)

Grass seed will stay good for at least a year and a half to two years, depending on the storage conditions (cool and dry). It will probably stay viable for longer - the only issue is that the germination rate will not be as high as with fresh seed.

Seed packages should show an expiration date. However, depending the grass species, if it is stored in airtight container and away from light and heat it can last for a year or so. When planted, it should sprout within a couple weeks, but if it doesn't it probably isn't good seed. You can plant a "sample" crop ahead.

Shelf life of viable grass seed depends on the storage method. It is best to keep in a cool, dark, and dry place.

The viability of grass seeds depends on two factor: the grass species and storage. If stored in an airtight, fresh, dry place, they remain viable for 1 year or more

Well grass seed can last for up to 3 years in optimal conditions. As long as you are keeping it in a warm climate or a cold one, they will be good to go. You just have to make sure that you do not put them in the heat as this will affect the seeds.
