Beechgrove Garden is planning for a colourful summer, planting for pollinators and caring for dahlias. Kirsty Wilson and Lizzie Schofield will have the usual half hour of great gardening advice, including a follow-up on how the dahlia tubers planted in pots in April are coming on, and what to do if you want to get some free plants by taking dahlia cuttings.Kirsty is sowing a bed around the viburnum that was moved last autumn, and this new area will be home to plants that are particularly good for pollinators. Calum Clunie will be sending an update from his allotment in Fife, and George Anderson is in Joppa. And it's the start of a garden renovation for a family who have recently moved into a new-build house.
