As the borders at Longmeadow hit their stride, it is time to take stock of what is looking good and what needs replacing. Monty shares his tips on how he keeps his displays going all summer long. There is plenty to do on the vegetable plot too, and things are looking promising in the fruit garden.

Adam Frost meets an extraordinary woman who runs a community project in the centre of Birmingham, while Frances Tophill catches up with her allotment. Joe Swift travels to Devon to a garden which has been designed around a challenging landscape, and Nick Bailey visits the restored Temperate House at Kew Gardens.

Whether there is a heatwave or a downpour, this week Monty has plenty of jobs to be getting on with, from pruning and propagating to planting pots. Adam Frost meets Prince Charles in his garden at Highgrove to talk about the issue of biosecurity, an issue which is of great concern to him and which could have a big effect on our gardens and landscape. Adam also talks to the prince's head forester to find out what gardeners can do to help.

Carol Klein profiles one of our summer stunners for both borders and containers - the agapanthus - and we catch up with Frances Tophill on her shared allotment. We also meet a gardener whose passion for planting has spilled out from his garden onto the roundabout outside his house.
