Horticulturalist Christine Walkden makes an exciting discovery in her garden and shows her neighbour Louise the joys of developing a garden over time.

It's June, and there's a hosepipe ban in place. But Christine is determined not to let her plants die. She digs over her beds and prepares the garden for summer, while also finding time to head north.

Despite Christine's best efforts, her plants are wilting under the summer sun. But never one to shirk a challenge, she takes on a 60ft long and 12ft high overgrown hedge armed only with secateurs.

Christine prepares to lead a horticultural tour to China, leaving care of the garden to her neighbours.

As autumn falls, Christine prepares the garden for winter and bets Reg that her tomatoes ripen indoors.
