Royal fans have gone into meltdown after learning that Prince Charles shakes hands with every tree he plants 'to wish it well'.

Taking to Twitter, the researchers behind the popular British comedy quiz show QI said that the Prince of Wales, 70, finishes each tree-planting ceremony by offering a handshake to one of the branches.

Clarence House has confirmed to FEMAIL that it is indeed a tradition of the royal's, and it's one of 70 facts about the heir to the throne published on his personal website.

It will come as no surprise to fans of the green-fingered prince who famously said in a 1986 interview that he makes his garden grow by talking to the plants.

‘I just come and talk to the plants, really – very important to talk to them. They respond,' he said.

Responding to the latest revelation, one person wrote: 'I think that's quite lovely,' as another said: 'That’s the most British thing I’ve ever heard.'

'That's surprisingly cute of him', a third added, while one person joked: 'I don't be-leaf it!'

The Prince of Wales' website documents his antics, writing: 'After planting each tree, HRH gives a branch a friendly shake to wish them well.'

The move - which is one of the 70 facts about the royal to be published on his personal website - was quickly praised by social media users

Charles' love for the countryside and its nature is well known, with the royal famously admitting he gives his plants a little verbal encouragement.

During a 1986 interview, the green-fingered heir to the throne, a champion of organic and sustainable farming, said: 'I just come and talk to the plants, really – very important to talk to them. They respond.'

He later confessed during a special 25th anniversary edition of BBC1’s Countryfile, that he not only chats to them but also trains them.

When asked if he still spoke to his plants, Charles joked self-deprecatingly: ‘No, now I instruct them instead.’

The heir apparent often works on his own patch of land, Duchy Home Farm in Gloucestershire.

Previously speaking in a BBC documentary, Prince Charles said: 'As I get older, all I really long for is to plant trees. I hope it will be quite amusing for George as they grow up and he grows up.'

And in 1985, when it was still a relatively new concept, Charles decided to convert the Duchy Home Farm into a completely organic farming system.
