I too watched about 3 minutes of the Flower Pot gang programme and had the same opinion as the majority.
Will definately try Beechgrove either on IPlayer or sky.
I read the GW mag each month and really enjoy Joe's articles on garden design. HEY! BBC - How about making a programme based on Joe's articles where he visits REAL gardens who use the same principles that he writes about in his articles? No expensive contractors to pay, just go to a real-life garden where I am sure the owner will be thrilled to show the viewer around, discuss design, materials used, planting for various aspects and conditions?
PS - Will definately expect a concept/ideas fee if this is taken up!!!
