The programme pays a visit to the RHS Malvern Spring Festival to see this year's hottest garden designs and the season's must-have plants. Carol Klein, Joe Swift and Adam Frost explore the event, sampling the best from the floral marquee and show gardens. Meanwhile, at Longmeadow, Monty Don plants herbaceous perennials for summer colour and gives timely advice on how to care for carnivorous plants. Plus, Frances Tophill catches up with the growing trend for greening up indoor spaces with house plants.
