A water-smart garden is a landscape designed and maintained to use water efficiently, minimizing waste while still supporting healthy plant growth. This approach involves selecting drought-tolerant plants, optimizing irrigation practices, and using water-conserving techniques.
PLANT SELECTION
-
Drought-tolerant plants: Choosing plants that are well-suited to the local climate and rainfall patterns reduces the need for supplemental watering.
-
Native plants: Native plants are naturally adapted to the local environment and require less water than non-native species.
-
Strategic placement: Grouping plants with similar water needs together can optimize irrigation and reduce overall water consumption.
IRRIGATION OPTIMIZATION
-
Targeted watering: Using drip irrigation, soaker hoses, or smart irrigation systems delivers water directly to the root zone, minimizing evaporation and runoff.
-
Watering deeply and less frequently: This encourages deep root growth, making plants more resilient to dry spells.
-
Avoiding midday watering: Watering in the early morning or evening reduces water loss due to evaporation.
-
Smart irrigation controllers: These systems monitor weather conditions and soil moisture to adjust watering schedules, ensuring plants receive the right amount of water at the right time.
SOIL MANAGEMENT
-
Mulching: A layer of mulch helps retain soil moisture, suppresses weeds, and regulates soil temperature.
-
Soil health: Healthy soil with good drainage and water-holding capacity is essential for plant health and water conservation.
LANDSCAPE DESIGN
-
Rainwater harvesting: Collecting rainwater in cisterns or rain barrels provides a free source of water for irrigation.
-
Swales and berms: These landscape features can help redirect and retain rainwater, improving soil moisture.
-
Reducing lawn size: Replacing turf with drought-tolerant plants can significantly reduce water demand.

CREATE YOUR OWN WATER-SMART GARDEN
Plan Your Design
-
- Sketch your garden layout, noting the sun exposure, plant size, slope, and drainage.
- Consider efficient irrigation using drip lines and smart irrigation controllers.
- Include other structural design elements, if preferred.
Prepare the Area
-
-
- Clear the space of existing vegetation and debris, noting the soil type.
- Improve the soil as needed with compost or fertilizer to support plant health.
- Install a weed barrier and cover the area with native mulch or decomposed granite.
-
Plant and Enjoy!
-
- Consider planting in early spring or fall to allow plant establishment.
