As spring gets well underway, Monty Don adds to his collection of fritillaries at Longmeadow with pot-grown plants, as well as sowing some from seed. He also recommends other wildflowers which would thrive in the garden. Carol Klein meets Matt Bishop, who explains why he is attracted to later flowering varieties of daffodils and demonstrates how he is using them to breed new ones. Rachel de Thame shows a viewer how to get to grips with pruning an overgrown shrubbery, and divides and plants easy perennials for a blaze of summer colour. Back at Longmeadow, Monty celebrates the versatility of the euphorbia, which will bring colour, form and longevity to all areas of the garden from full sun to dry shade, and begins work on planting a variety of ornamental vegetables, such as ruby chard and red cabbage.
