Sam Fenwick explores why peat is such an important carbon store and whether it’s use in compost should be banned. Sam visits a peat bog in the UK and speaks to garden centres in Japan and India, where like many parts of the world gardening boomed during the pandemic. She also heads to Estonia, one of the biggest exporters of peat in the world.
