Season 1 2015

The competition starts at RHS Harlow Carr in Harrogate, where the designers are given four days, a 3x4m plot and a limited budget to create a show garden in the Cottage Garden style - a mini Chelsea. They are sent to a local wholesale nursery to source their plants and are helped and mentored throughout the process by Joe, who won a gold medal at Chelsea in 2012.

The five remaining designers are sent to the impressive Sudeley Castle in Gloucestershire, where they have to create formal gardens on a 4x4m plot. They have just four days to complete their garden and being a formal garden, they have to include a piece of topiary - a two metre-high yew hedge that they have shaped themselves.

Only four designers remain and this time they have come to Painswick Rocco Gardens in the heart of the Cotswolds. This week they have to create conceptual gardens which will showcase their creativity and impress judges RHS judge James Alexander Sinclair and Chelsea gold winner Ann Marie Powell.

The three finalists go to the RHS Headquarters in Wisley where they have five days and their biggest budget yet to create a show garden that will prove they are a worthy of winning the biggest prize in gardening - to design a garden on the Main Avenue at this year’s RHS Chelsea Flower Show.
