Monty Don kicks off the gardening year from Longmeadow, sharing his tips for pruning, planting up pots for spring colour and sharing his plans for the coming year. At the National Trust's Packwood House in Warwickshire, the herbaceous borders come under Adam Frost's scrutiny as he finds out how they have been planted for maximum colour and impact. Over the course of this 50th series, Carol Klein will be sharing some of her heroes of gardening. She begins with plantswoman, garden designer and author Beth Chatto.
