Ask the Expert: 11 Tips for Designing a Water-Conscious Garden


Ask the Expert: 11 Tips for Designing a Water-Conscious Garden

February 26, 2014

With offices in Phoenix, Arizona and Austin, Texas, landscape architect Christine Ten Eyck knows a thing or two about designing in arid landscapes. Lest you think the solution to designing a water-conscious garden is to cover the ground with hardscape and gravel and give up on the plants, we’ve sought out expert advice for fostering lush desert landscapes.

Before pulling out your divining rod and praying for rain, consider implementing her tips for designing a garden in an area where water is scarce:

1. Use low-water native plants and don’t over water. Consider a beautiful low-water succulent garden and plant sedums, agaves, yuccas, and prickly pears.

2. Harvest air conditioner condensate and use to water plants. The beauty of this is that you get the water when you need it: in the summer in hot weather.

3. Use trees as the backbone of the garden. Trees give shade and keep the ground cooler. (Don’t forget to deeply water trees in times of drought.)

4. Build a brimming water feature. Stay away from fountains with jets that tend to lose water to spray. Instead, learn from the Moorish gardens in Spain and build a fountain that uses the least amount of water for the most effect.

5. Harvest rainwater in cisterns or by creating swales. Direct the water you collect to trees and gardens.

6. Use drip irrigation and separate shrub valves from tree valves. Drip irrigation helps maintain optimal soil moisture throughout the season and not just in times of drought.

7. Use permeable pavers and gravel for gathering spaces and driveways. This allows water to penetrate the soil (don’t use plastic underneath).

8. Use mulches and compost on and in soil. Both help retain water.

9. If you have a sloping lot, create check dams with stone or salvaged broken concrete. Check dams slow rainwater when it does come and help the water to percolate into the soil.

10. Create microclimates. Use walls and shade structures to shade sections of the garden from the sun.

11. Shower outside with biodegradable soap. Direct the runoff water toward the plants. Photograph by Terrence Moore.
