Monty, Joe and Carol are joined at Berryfields by Sarah Raven for another indulgent hour of gardening. It's all about colour as Monty and Sarah plant up the green garden with foliage, flowers and texture, Joe injects some structure and seasonal colour into the dry garden, Carol is planning for hot summer purples and oranges in her garden of seeds and cuttings, and Sarah shows how to grow the rich hues of late-summer flowers.
