Episode 8

Monty is busy this week as the garden bursts into colour. Woody herbs such as thyme and sage don’t thrive in his clay soil, so he’s sowing seeds to ensure a steady supply. He’s planting grasses in the new Woodland Garden and creating a colourful pot for shade, and there's advice on what to do with this year’s daffodil bulbs.

Carol Klein proves that small can be both beautiful and delicious, creating a modest border devoted to vegetables and weaving it together with flowers to provide year round colour. And Advolly Richmond heads to Fife to uncover the story of the first pink cupped daffodil, bred in the early 1900s and still growing today thanks to two passionate plantswomen.

There’s a visit to a specialist nursery in Somerset. With help from the Royal Botanic Gardens, Kew, they are preparing to exhibit trees fit for a changing climate at the RHS Chelsea Flower show. And it's all aboard a houseboat that's jam-packed with plants.
