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.
