Hydrozones: split your garden to irrigate better
Hydrozone planning assigns the right amount of water to each area and is one of the most effective ways to save water.
What a hydrozone is
A hydrozone groups plants with similar water demand, exposure and soil conditions into one independently controlled zone.
Typical residential hydrozones
A practical split is high demand turf, medium demand shrubs/perennials, and low demand Mediterranean plants.
How many zones you need
For many homes, 3-4 zones are enough to capture most efficiency gains without overcomplicating installation.
Map them before installing
Defining boundaries on a map makes it easier to verify coverage and run-time strategy before buying components.
