    Does your fertilizer expire or can I use up what I bought last year? Thanks

    Andrea –

    Some fertilizers have an expiration date if they contain mycorrhizae fungi, which is a living organism. However, the NPK portion of your fertilizer does not expire and will continue to provide benefits.
