Obelixx, I too feel that the Geoff Hamilton years were the high point, but I didn't really care for Alan if I'm honest. The programme seemed to go from 'here's a great little tool you can make for yourself by recycling an old.....' to 'you can get one of these from your local garden centre'. But then that era - the late 90s and early naughties seemed to be about quick fixes - garden makeovers, unlikely paint colours, an army of bought in plants and ornaments and decking and ponds that must have cost a bomb - lots of weird impractical designs. I like Monty though - I'm not sure the common touch means much to me, but I prefer my gardening shows without too much ego, and I feel that what Monty has in common with Geoff is the fact that both are there for the plants, not the chat shows or book deals. My fondest memory of Geoff was him telling us how to make stones for a rockery by burying concrete in plastic sheeting. I liked the experimentation. What I like about Monty is his use of language - his narration on the French garden series painted pictures with words, and both he and Carol Klein have an infectious enthusiasm. I do still enjoy GW a lot. Oh and Nigel the dog is a star.
My memories of GQT are of Fred Loaves, Bill Sowerbutts and Professor Alan Gemmel of Keele University! Which is probably enough to date anyone. I was just reading that Beechgrove is going to come to England in the next series - I hope that will not be disappointing to those north of the border, but it is an indication of its charm and unique place in the hearts of gardeners that it is spreading its wings a bit. I expect that they have taken on board the point that by staying in Scotland they are a bit behind the rest of the country.
