Rivers, tanks and aquifers

The Water

Murray–Darling politics at kitchen-table scale, tanks that do not breed mosquitoes, and creeks that still remember rain.

A productive vegetable garden with dense beds, foliage and narrow paths

The Water

Drought-ready gardens that still look like a garden

A dry-climate garden does not have to be gravel and a single sculptural agave. Hydrozoning, mulch, honest plant choices and a tank can keep a backyard looking inhabited through a restriction summer, without pretending the hose is a climate strategy.
