It's the semi-final of The Big Allotment Challenge hosted by Fern Britton. The search continues to find Britain's Best Growers. Five teams are left to battle it out for a place in the final. In this episode their onions and chrysanthemums are laid bare on the show bench for Jim to judge. In their biggest task yet, Jonathan challenges the allotmenteers to create a pedestal that includes chrysanthemums and other flowers from their patch, whilst preserves expert Thane Prince sets them the tough challenge of making well set jellies and smooth fruit butters. Who will leave the allotment for good and who will score on the show bench and make it through to the final with a chance to be named the winners of The Big Allotment Challenge?
