The Duke and Duchess of Cambridge are making some delicious changes to the grounds of their home in Norfolk. The couple have hired garden expert Robin Parker to help them plant flower and vegetable gardens at Anmer Hall.

The Sun revealed that Kate hired Robin to help her become a better gardener. "He’s helping her become more self-sufficient. She loves cooking stuff she’s grown," a friend of the duchess said.

"It’s all a bit like Barbara and Tom in BBC TV comedy The Good Life." In the '70s BBC program, Tom and wife Barbara decide to turn their suburban back yard into a farm.

The couple have hired a gardener to help them transform their garden.

It's not only flowers, plants and trees for which Robin has been hired. His duties include looking after swings and climbing frames for Prince George, 2, and eight-month-old Princess Charlotte.

Prince George may even give a helping hand in the garden as the toddler assisted his granddad, Prince Charles, plant two trees in Highgrove House in June.

However, the 47-year-old gardener is tight-lipped on the matter. "Due to the nature of people I work for, I am not allowed to talk about the job," Robin said.

The gardener will also look after swings for the royal children.

The royal couple are spending $3 million on renovations for the house, including an extensive tree-planting program to give the family of four more privacy.

Last year, the couple hired a new housekeeper, Sadie Rice, 34, who had previously worked for Norway's Crown Prince Haakon and his wife, Crown Princess Mette-Marit.

With Sadie, Spanish nanny Maria Teresa Turrion assists with the child care for the two tots as well as looking after the family dog, Lupo.
