Is there any reason not to use up last year's still bagged compost if you
add more nutrients?


Or without bothering to do that! Most nutrients do NOT reduce with
time, and the only one I can think of that would is nitrogen, and
then only if the compost has been kept damp. I regularly use such
things 5 and more years old, without trouble and without adding
anything (at least for a short period).

Anyone know where the OP's assumption might have come from? Has it ever
appeared on the bags themselves as a sort of shelf life?
