A look back over the past year to some of the best bits of our gardening podcasts. In March we met the staff and inmates at HMP Hull to find out how an award-winning prison garden has helped transform lives behind bars. Plus garden writer Sally Nex charts her quest for a plastic-free plot, and we discover what curators, editors and other RHS staff members are most looking forward to horticulturally in 2020.
