Old compost

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.


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