Ahead of the coronation weekend, there is a slight royal theme to the work going on at Beechgrove Garden. Carole Baxter and Calum Clunie will be planting delphiniums, reportedly one of the favourite flowers of HM King Charles III. Elsewhere in the garden, Carole starts to refresh the planting in the Garden for Wildlife with a selection of varieties known to help pollinators and other species. Calum replants some of his underperforming roses from the end of last year, and Brian Cunningham sends another report on the work he is doing at his garden in Perthshire. And there is the next in Beechgrove's Back to Basics skills guide.
