C5 digs into “The Great Garden Challenge” from Crackit

British commercial television network Channel 5 is prepping a six-part gardening competition series from London-based TV prodco Crackit Productions.

The Great Garden Challenge (w/t), features eight teams in head-to-head competition vying to win the title of Great Garden Challenge Champion and the opportunity to exhibit their garden at the Royal Horticultural Society’s Garden Wisley.

In the first four episodes, the contestants compete in heats with two pairs of professional garden designers facing off to transform identically sized spaces while on a strict budget and a 48-hour deadline.

At the end of each heat episode, both spaces are visited by the shows judges, Carol Klein and Mark Gregory, who assess the gardens according to Royal Horticultural Society criteria for a good garden, which includes the design and how they’ve planned the space, as well as construction and landscaping, and more.

Four winning pairs from the heats go through to the semi-finals before moving into the grand final. In the final episode, the remaining two pairs of garden designers will be tasked with creating a show garden for the RHS’s flagship site, Garden Wisley in Surrey. Wisley’s curator, Matthew Pottage, will guest judge and help crown Britain’s Best Garden Challenge champions.

Klein and Gregory are joined by garden designer Diarmuid Gavin and broadcaster Nicki Chapman as show judges.

All the garden spaces used in the competition challenges are created for deserving causes, the network said.

Elaine Hackett and Jason Wells serve as executive producers for Crackit Productions.

The Great Garden Challenge will premiere on Channel 5 in 2019.
