Spring reminder, as people start to think about gardening: NEVER buy compost with peat it in (inexplicably still on sale). If it does not say "peat free" in big letters, do not buy it. Peat is incredibly valuable in peat bogs, for rare biodiversity and as a carbon store. Don't put it on your garden!
