Leaves are falling in the Beechgrove Garden but that's not necessarily a bad thing as Jim uses them to make lovely leaf mould. He also shows the steamy secrets of his new hot box composter. Carole makes her last visit to Mieke and family in rural Aberdeenshire where they are gardening on a budget and this week they learn how to shred material to make economical but pretty paths. Jim knows very well that gardening is good for you but this week it's especially so as he marks the 10th anniversary of Trellis, which is designed to support therapeutic gardening as he visits a really restorative nursery and garden, Solstice, in Banchory-Devenick.
