Gardeners’ World, 8.30pm, BBC2

THE hour-long specials of the gardening show continue, and Monty Don has his secateurs at the ready to demonstrate how to tame unruly roses, and also plants a tree. Away from Longmeadow, Nick Macer visits a London garden that has two different microclimates, and Flo Headlam helps to transform grey urban areas in Bristol with vibrant foliage.
