This year the show has a special focus the apple. The Two Thirsty Gardeners (Richard Hood and Nick Moyle) will demonstrate how to make homebrewed cider with recipes from their new book Brew it Yourself, and cultivars from RHS Garden Wisley will be for sale.
From 23-24 October the RHS London Shades of Autumn Show in Westminster will celebrate autumn colour, again featuring specialist nurseries and expert talks.
Among the exhibits, Petersham Nurseries will hold workshops on how to create the trendy Japanese kokedama - houseplants with rootballs wrapped in moss and hung from the ceiling.
The show will also feature an exhibit on the Garden Bridge project, giving visitors the chance to learn more about the project's development.
