We join Blackshaw Head Optimistic Gardeners - aka Gardeners With Altitude - near Hebden Bridge, West Yorkshire.
Pippa Greenwood, Bob Flowerdew and Christine Walkden form the panel. Eric Robson is the chairman.
We also introduce the fourth GQT listener whose gardening projects we will mentor and revisit over the coming months. Part of our Listeners' Gardens series.
