We’re looking forward to watching The Queen’s Garden on Christmas Day for a fascinating insight into the royal gardens.

Alan Titchmarsh is given behind-the-scenes access to the 39-acre grounds at Buckingham Palace over the course of a year and uncovers lots of secrets and intriguing facts along the way.

As the greenery changes with each passing season, Alan investigates the history of the estate.

In the first episode of the two-part series the presenter starts his journey at the summer garden party.

Whilst the 8,000 people invited to the bash enjoy the festivities, Alan heads off to look for wild spaces of the foliage inhabited by nature.

He also meets beekeeper John Chapple who harvests honey on the Buckingham Palace land.

As Alan continues to delve into the past, we find out some interesting details about the history of the gardens. We can’t believe that it was once a part of Henry VIII’s hunting ground!

The Queen’s Garden continues on into late summer, where Alan visits the Rose Garden and its 18th century summer house.

Seeing how the greenery evolves when the autumn arrives is a lovely sight and the events held on the grounds change too.

There’s a special football match taking place so the lawn has to be carefully prepared ahead of the game.

Alan also chats to deputy gardens manager Claire Midgley-Adam as she tries to save a very special tree. The historic shrub was planted by George VI, the Queen’s father.

Soon Christmas arrives and it’s time to decorate the palace with beautiful flowers.

Royal florist Sharon Gaddes-Croasdale is assisted by Alan when she adorns the house with festive holly and mistletoe. We bet it looks stunning!
