In the documentary, the King also discussed the importance of rescuing rare cultivated plants, something he has showcased at Highgrove.
While walking around the gardens he has nurtured since 1980, he says: “I wanted to find ways of ensuring that you could rescue all these threatened heritage varieties.
“Everything, all the vegetables, potatoes, cauliflower, peas, beans … I mean, a lot of them were being just abandoned.
“So, I did my utmost to have as many rare breeds here as possible to demonstrate how valuable they are, because it was concentrating on just a few varieties makes us unbelievably vulnerable, as we’re finding, to disease and everything else.”
The monarch has also restored the gardens on the 20,000-acre Sandringham estate in Norfolk, creating a topiary garden, a thistle-shaped maze with a sundial as a centrepiece.
