At Longmeadow, Monty Don plants out his tomatoes, continues work in his paradise garden and reveals plans for a new project. At the Malvern Spring Festival, Adam Frost, Carol Klein and Frances Tophill explore the show gardens and highlight the very best of the plants and flowers in the floral marque. The programme also visits a city garden in Peterborough where lack of space has not proved a problem for a couple who have created a woodland garden, and hears from a Cambridgeshire man who has devoted his gardening life to the preservation of rare and heritage plants.
