How long does fertilizer keep?
Specifically, the timed-release pellets. I have some Nutricote and some Peters in the shed that have been there for, oh, 2 to 4 or more years. The shed is under the deck in a corner formed by the house, so it's shaded and somewhat protected, but it has no climate control.
Will the temperature extremes have taken enough of a toll on the fertilizer that I should just chuck it? There's not that much left, but I hate to waste it if it's still OK.
