In the final programme from Longmeadow this year, Monty harvests his pumpkins and has plenty of inspiration for jobs we can be getting on with over the coming winter. Frances Tophill travels to Winkworth Arboretum in Surrey to celebrate the season and to explain the science behind the golden and red tones of autumn leaves. For winter inspiration, Adam Frost is at a garden in Doncaster where water, grasses and seedheads all add to the design. There is a second chance to meet twins Stuart and Ian Paton to find out what it takes to grow the biggest pumpkin in the UK. And the team revel in the films of the gardens and gardeners viewers have shared with us this year.
