It's a tale of high summer and mid-winter at Beechgrove Garden this week. Kirsty is checking on her hot border, designed to be a riot of colour in high summer. Meanwhile, Calum is at his allotment in Leven, where he is planting potatoes to serve up for Christmas dinner. Back at Beechgrove, Scott demonstrates how to prune a rambling rose.

Carole Baxter presents the latest Back to Basics feature, and she's talking about the many bugs, blights and diseases that can attack plants: what they are, what damage they can do, and how best to stop them.

Diana Yates and Calum Clunie are also at the garden. Diana reviews her own 'vertical garden' area at Beechgrove that demonstrates planting ideas for those with small gardens and balconies.
