My personal view on the Chelsea Flower Show.
I first went about 10 years ago and really did not enjoy it. It was hugely crowded and more full of people who wanted to see and be seen than were really interested in gardening. Lots of dressing up and ogling at celebrities. The show gardens seemed to me to be more about architectural design than planting.
I'm involved with the charity WaterAid and this year was invited to volunteer at one of the show gardens which the charity was involved with on the theme of rainwater harvesting and coping with the challenges of climate change. My wife and I did some shifts on the Tuesday and Wednesday, both RHS members days, giving out leaflets and talking to them about the garden. This was great fun despite terrible weather on both days, talking to lots of different people, most of them at least a bit interested in the garden.
We had some time away from the garden to look around and I did notice a definite movement in the style of the gardens, away from an emphasis on structures and much more emphasis on the planting. The WaterAid garden was hugely impressive (I admit a possible bias here!) but I also enjoyed several of the other gardens, both the main show gardens and the various smaller ones.
Would I go again as a paying customer? Probably not, but I might take up a free or discounted ticket if I was going to be in the area. I still believe that the RHS shows and the permanent gardens provide a more interesting day out.
