In a special programme coming from York Gate in Leeds, Adam Frost, Rachel de Thame and Frances Tophill celebrate a garden for all seasons and tackle some seasonal jobs for September. 

In London, we meet a head gardener who fell in love with horticulture at a very young age, while plantsman Jamie Butterworth pays a visit to the magnificent walled garden at Scampston Hall. There’s also a man in Norfolk with a lifelong passion for breeding hibiscus.
