I shall be pleased to see Monty back on GW. He is a passionate gardener, even though he may not be "trained" - as so many people have commented. So he makes mistakes? All gardeners do, professional and otherwise, that's how you learn. Personally, I admire his organic approach to the whole garden. As he's pointed out many times, there's no point in only growing your veg organically whilst spraying everywhere else, a garden is a holistic thing.
However, having said that, I was beginning to warm to Toby. The first year that he fronted GW, I was appalled and thought I'd tuned into a (poor quality) children's gardening programme by mistake. This was not Toby's fault, it was undoubtedly the production team trying to make GW more "modern" and "fun". Nauseating. The following year, when Toby was allowed, it seemed, to do things in his own way, there was a vast improvement and he seemed to blossom.
So, good to have Monty again, but I feel that Toby has been very shabbily treated. I shall miss Alys as well.
