In the final programme from Longmeadow this year, Monty harvests his pumpkins, plants bulbs in a pot and has plenty of jobs we can be getting on with over the coming weeks.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. The team takes inspiration from RHS Harlow Carr and has a look at their winter borders and the plants which will add interest and drama to gardens over the coming months.There is a second chance to meet a woman who has inspired a generation of young people and taught them gardening skills from her garden in the West Midlands, and the show revisits Hampshire twins Stuart and Ian Paton to find out what it takes to grow record-breaking pumpkins.
