Glorious Gardens from Above

Christine Walkden's balloon travels over the flattest part of Britain as she descends on Norfolk.

At East Ruston Gardens she helps cut a hole in a hedge and meets Kathryn, a very determined woman. At the Bressingham Gardens, Christine assists in preparing a tree for felling and we discover the fascinating human history of the Norfolk Broads.

Christine Walkden flies above the green expanses of Hampshire, dropping in on two spectacular gardens.

At Mottisfont she meets a gardening veteran who's handing over the reins to his young protegee, and at the Sir Harold Hillier Garden she learns about keeping it in the family. And she climbs into a pair of waders for some very unusual weeding.

Christine Walkden heads to the Scottish county of Aberdeenshire.

Her balloon takes her to Crathes Castle, ancient seat of Scottish nobles, where she learns about the challenges of gardening in an unforgiving climate and meets Doug, whose father left his mark on the estate. And she gets to grips with some smelly skunk cabbage at what claims to be Britain's highest garden, Tillypronie.
