Hydrozoning is the strategic grouping of plants based on their needs, in order to conserve water. A system like this allows for more efficient irrigation schedules, which better satisfy each plant’s needs, while helping to avoid over- and under-watering.
Water Intensive Zones should be closest to the house, near the water source, and receive more shade.
Drought-Tolerant Zones can be created further from the house, in areas that receive lots of sun and away from trees or lawns that require more water.
You can also create Moderate-Use Zone for plants that require moderate amounts of water and shade.
Whether starting from scratch or just adding one-at-a-time, having a strategy for placing plants in your yard will help you save water and keep bills down.
