I have bought too much seed compost, if the bag remains unopened and I store it in a dry warm place, will the nutrients in it last to next year?
I mix mine in with the MPC for use in potting on.
funny how things turn around.
I'm old enough to remember the scare stories about NOT buying JI compost as it was depleting the loam beds in Surrey and we should all switch to peat based composts.
I thought compost for sowing seed was intentionally low in nutrients anyway - so I wouldn't be too worried about that aspect of storing it. You should be ok as long as the bag is intact - it is a bit of a nightmare rehydrating compost which has completely dried out - only suitable for use as a soil improver really.
Great, thanks all
Why buy seed compost? I have never used it, only use multi purpose and never had a failure.
