Escalating food prices, and all that land out back? Put the two together and turning your place into an edible garden is a no-brainer. But even if you’re squeezed into a concreted corner or you’re halfway up a towerblock, there’s still room for some horticultural creativity. Agricultural skyscrapers are on the rise (as it were) but while city-planners develop a coherently green strategy, it’s all about self-expression. Snake some vines over your balcony or up the wall. Let your potted plants grab onto windows and railings. Make your city come alive!
