I guess it's horses for courses. I like Monty Don's thoughtful demeanour - I think he puts gardening in context - although I agree, I'd like to see a bit more practical content and more on growing technique. I also think the programme suffers from MD being on his own mostly at 'Longmeadow' - more dialogue between presenters would liven things up. Personally I loathed the Toby-led show - nothing to do with the poor man himself, but the change in direction and format that the Beeb had obviously decided on which and the producers and presenters had to comply with. I think Toby & co were stitched up in that respect. But I hated all those silly DIY projects - like giant planters working out at about £800 apiece - that no normal gardener could afford, and I felt the whole programme was severely dumbed down. I'm sure Alys will pop up again somewhere on telly soon, good plantswoman that she appears to be, with her fresh and environmentally-friendly approach. Perhaps the show's bosses felt she was too similar to Carol in terms of contribution - and the viewers love Carol with her vast knowledge, down-to-earth attitude and huge enthusiasm for plants.
Just goes to show, doesn't it, you certainly can't please all the people all the time?
