Will 2year old John Innes compost, in an unopened bag, still be good to use. It has been kept dry and out of the sun.

    Yes.

    Did you think that the nutrients might've disappeared into thin air?

    No, but have had such mixed advice, so I thought best to ask here. Thank you.

    I'm interested in what other advice you've heard.

    At worst it will still make good soil conditioner.

    Thank you. Someone said how do you know how old it is when you buy it early in the season!

    Interesting. I've heard too that you should use compost as soon as possible and not store it for years.

    The carbon and nitrogen are still in the bag, it doesn't just disappear. Unless there's another reason why "people" say it should be used asap? I'd be interested to read any science on this.

    Thank you for sound scientific advice, weather looks good too, so outside and busy today.

    IMHO, worst case scenario is you'll have to feed plants earlier than usual
