Keep them dry and they should be good indefinitely.

On the other hand, if you use anything like organic fertilizer, that should all go down before the winter. It can get buggy by spring.

Good point. Corn in particular, or anything edible, don't keep that around. I kept a bag of corn cobs in the garage over winter for squirrels and found a good amount of it stashed in every nook and cranny of my tractor engine. I fired it up in the spring to mow and after a few minutes it started smelling like popcorn. Apparently some creature hauled it out of the bag a little at a time and stashed it there. Took me a whole day to take the engine out of the tractor, take all the tins off, clean it up and put it back in.

That's a pain! Good to know, thanks for the tips!
