The research for the perfect replacement for peat

The research for the perfect replacement for peat is far from over, but many peat-free growing media have already been in use for decades. So what are the main options? Coir, which is made from the long fibres in the outer husks of coconuts, has been used for decades in growing media and is currently the most widely used peat-free alternative, says Jackson. "It's the close first cousin to peat in properties, and it's been used enough that there's familiarity with how to use it to grow plants."
