Gardeners' World : Season 49 Episode 14

Whilst celebrating the glory of summer flowers at Longmeadow, Monty has plenty of tips, from pruning and propagation techniques for different types of clematis to troubleshooting problems with roses. Carol Klein wades through streams and marshes to show us how gardeners can emulate nature when choosing the right water plants for our gardens, and we visit Norfolk to revel in an extraordinary collection of iris.
