The Chelsea Flower Show, dubbed the Olympics of Gardening by the gang here in the office, comes to an end this weekend, with the crowds gathering to buy up most of the plants that were used to create some truly spectacular gardens. Alan Titchmarsh is back for one final show this eve, and will be sitting down to chat about the week that was with Joe Swift and Nicki Chapman. And, of course, there's a very important award to be handed out, with the winner of the Royal Horticultural Society People's Award being revealed.
