The show, a celebration of the season's finest fruit, flowers and veg, will be previewed by Presenter Joe Swift on tonight's BBC2's Gardeners' World (1 October).
The programme will follow Joe as he attempts to take his vegetable growing to another level, with the aid of experienced Welsh grower Charlie Maisey.
The question is - will Joe Swift be lifting a Haxnicks' Bell Jar at the end of the competition?
To find out tune in to BBC2 1 October at 7 pm, staying tuned to the RHS web site and to this blog, and our Twitter and Facebook pages to find out the results next week.
Haxnicks are very pleased to be supplying Glass Bell Jars to cover the medals at this year's RHS' Autumn Harvest Show, on this weekend at The RHS Horticultural Halls at Greycoat Street, SW1. Nearest tubes are St James's Park and Victoria.
