Where have all the worms gone in my garden? How do I use a glasshouse? Can plants survive without being watered for a month?

Kathy Clugston and a team of gardening experts explore the 70 acres of the Royal Botanic Garden Edinburgh, all while digging the GQT postbag to answer your gardening grievances.

Joining Kathy on this extensive tour are ethnobotanist James Wong, garden designer Neil Porteous, and Head of Gardens at Balmoral Kirsty Wilson. They're led around the garden by Head of Collections, David Knott.
