Overview:In the final programme of the Beechgrove 40th anniversary series, Jim and George batten down the hatches and prepare plants for winter. Brian gives the alpine garden an autumn clean and adds some new tiny bulbs to the miniature alpine landscape. Chris makes the most of the season by showing how to have plants for free for next year. With Halloween approaching, George visits a spookily good pumpkin farm at Arnprior, and he tries his hand at some terrifying chainsaw pumpkin-carving.
