Hey all. This may be a real dumb question: Does compost go out of date. I have a bag of potting compost in the shed now for about 2 years its dry and clean i was gonna use it to pot some tomatoes or salad leaf or something would it still be ok to use. Many thanks.......TGG.

The nutrient balance in it can change - nitrogen, for example, can go up. Rather than throw it, or use it as mulch to improve garden soil, mix half and half with some fresh compost and use it.
