This week, Gareth Richards and Guy Barter discuss the science behind autumn colour, why some years are more dazzling than others, and what we can expect to see across the UK this year. RHS Horticultural Advisor Jenny Bowden will share a Love Letter to her favourite tree that promises to shine bright at this time of year and has a distinctive smell that would tempt anyone. We head to northeast Scotland, to explore an RHS Partner Garden - Gordon Castle Walled Garden - to find out what visitors can expect to see at this time of year, and to find out more about the history of one of the UK’s largest kitchen gardens. And we hear from the RHS Garden Wisley trials team about the results of this year's lily-flowered and fringed tulip trial and ask what we should be planting this autumn for a great display next spring.
