Mediterranean (semi-arid) gardening is undergoing a forced transition with climate change bringing it closer to desert conditions in certain southern regions with prolonged, intense summer heat.
Half the book covers hints on methods of irrigation, pruning, fertilizer and watering needs (less is more) and on choosing plants for micro-climates in the garden in shade, under trees, and winter protection, as well as selections for year-round colour.
The plant section contains lists of trees, shrubs, ground cover plants, vines, cacti and succulents, grasses and palms which are described with photographs. Many will be familiar to seasoned Mediterranean gardeners but there are also lesser-known suggestions.
Having gardened years ago in the southernmost region of Catalan France (42°N), I was able to grow a fascinating array of unfamiliar plants, succulents and hardy desert specimens from Mexico and Australia, notably suited to the harsh summers, many of them appearing in this book. Interestingly, several of the varieties did not survive when I moved to the Côte D’Azur, one degree further north, 15 years ago, to a then gentler climate. But that was then. Global heating is forcing southern gardeners to rethink their planting and Noelle Johnson has the experience to offer valuable pointers.
