I've been a few times and hope to go again....it's good to see plant combinations, see new hybrids, talk to growers and experts, pick up catalogues wander around the gardens ( I like the Yorkshire one too) etc. It also acts as a competition for nurseries and organisations and is an enjoyable day. Since I'm an RHS member I can get tickets if I remember to apply early in the year. ( which I often don't ) The only problem is that you really do have to get there as early as possible and head straight for the bit you want to see most, ( the main marquee in my case ) otherwise it gets horribly crowded. I would like to see the show gardens have less of a fantasy aspect and more that can be translated to an average suburban garden, but there are always the small gardens for that. It's a good, but tiring, day out if you are interested. Maybe next year ?
