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.

It's the first Beechgrove Garden of September, and although autumn is knocking on the garden gate, there is still lots to do for Kirsty Wilson and Calum Clunie.

Kirsty is dealing with the dahlias and showing us how to take hydrangea cuttings. Meanwhile, Calum is reviewing the clover lawn he sowed earlier in the year and catching up on the sweet corn planted in the polytunnel.

Carole has another instalment of Back to Basics, which this week features a look at plants that would suit a seaside location, and George Anderson is back on his allotment in Joppa.
