Does Grass seed go bad? - Page 2

 
Grass seed....  That covers alot of territory.

I've kept some unused 50 lb bag of winter rye in the garage in the original
container, it was never cold enough here in S. Texas to use this year.
Mostly dry and hot here, garage is very dry but usually cool.  No critters
around.

Just bought some bermuda (sahara variety) and seeded alot of bare areas.
Used half the 15 lb. bag.  Storing in same location in original container.

Think both will be alright for a few years or so for myself.  Yourself?
Devil's in details.  Which, of course, wasn't provided.  Am not surprised.

 A lot depends on how it's stored.   Leaving it in a garage, where it's
exposed to heat and humidity, is not a good place.   It will last a lot
longre stored in a cool, dry place.   I put mine in a closed garbage
can, with a container of the dessicant moisture absorbing stuff inside
and keep it in the basement.

The germination rate will decline slowly over time.  I've stored it for
several years and gotten good results.   If you have enough of it,
prior to using it, I would count out 50 seeds, plant them in a
container, and then count how many germinate.   Then you can adjust how
much to put down.
