So how do they do it? Beginning a year in advance, they begin with designs (which change every year) and scale models. Then, the day before the flowers are installed, rolled turf is placed between the floral patterns. 700,000 flowers are packed in tight (300 per meter/sq!), without any soil used at all! The flowers actually create their own microclimate. And how long does this take? It takes 100 gardeners four hours to put together this giant, living "paint by number". How awesome is that?
