Maytime in Chelsea. English summertime arrived - as usual - with howling wind and gusts of rain. But the Chelsea Flower Show must go on. So 150,000 gardeners crowded into the biggest marquee in the world. They inspected everything, from orchids to aspidistras, and spent £280,000 in orders in four days. Esther Rantzen and a Man Alive team were there behind the scenes - and well before the scenes: with the man who froze his daffodils, and the General who grows dwarf pomegranate trees. They saw the Queen - and an East End Parks superintendent. They found mystery, drama, excitement and suspense - and the largest strawberry in the world: all at this year's Chelsea Flower Show.
