In a special programme, Monty and the team celebrate the wonder of trees and explore the vital role they play in our gardens and the wider landscape.

Toby Buckland visits a tree project in North London which is all about engaging children with nature, growing and sustainability, while Nick Bailey gives us his ultimate guide to the top trees for your garden.

We visit a ground-breaking project in Staffordshire, which is using living experiments to monitor the crucial part trees play in mitigating climate change, and Arit Anderson finds out how planting more trees can support both humans and the planet.
