In this special edition one-off episode, the heir to the throne allows cameras into the Highgrove garden to discuss his love of nature and what we can do to protect our native plant and tree species.
Having helped transform the Highgrove garden from the unkept plot it was 40 years ago, to the verdant, picturesque space it is now, the Prince is something of a green-fingered expert.
Charles also warns Brits not to bring plants back from abroad to avoid the spread of foreign disease, reveals his own gardening failures and discusses the Action Oak charity which focuses on protecting our beloved oak tree.
He also discusses the measures taken to protect the plant-life within the Duchy of Lancaster estate which covers a rather substantial 53,000 hectares over 23 countries.
Other features of the episode also include how to prune, propagate and plant, no matter the weather.
