How long does fertilizer last???

Anyone have any I dea how long Mixed nutrients (in water) can be stored? If kept in the dark and capped?

also, any one know how long an opened bottle of say, Alaska fish emulsion big stay "good" for?

I bought Alaska fish emulsion from raleys but this bottle is OMRI-listed. and I know that Alaska fish fertilizer hasn't been omri-listed for a year or more now. It was sealed when I bout it.

Plants love it, I just hope it's "good" and will last now that I've opened it. because there's nothing eles like it that's OMRI-listed.

i think it has a 1-2 yr shelf life....but it depends what kind it is

check the website of the manufacturer to be sure
