Essential Guide to Water-Wise Gardening in California
Water-wise gardening in California isn’t just a trend—it’s a necessity. California’s climate is no stranger to long dry seasons, severe droughts, and water restrictions.
With over 60% of the state experiencing drought conditions in any given year, it’s becoming more and more difficult for residential, commercial and institutional property owners alike to justify water-intensive landscapes.
So what if you could choose a landscape that thrives because of these conditions, not in spite of them? And incorporates fire-resistant landscaping elements?
One of the gardens we’ve designed at Water Efficient Gardens
Water-efficient gardens are beautiful alternatives that naturally require less water. But water-wise gardening goes beyond saving water. It supports local ecosystems, reduces maintenance costs and water bills, and creates stunning, climate-resilient outdoor spaces.
This guide walks you through the basics of how to design a garden that flourishes under California’s unique environmental conditions—using proven strategies, native plants, and efficient watering systems.
Whether you're starting from scratch or converting an existing lawn, you’ll find practical steps and inspiring ideas to make your garden more sustainable—and stunning.
Water-wise gardening is a landscaping approach that minimizes water use through smart design, drought-tolerant plants, and efficient irrigation. It’s not about sacrificing beauty—it’s about creating vibrant, climate-adapted gardens that thrive with less.
Again, water-wise gardening in California isn’t just a smart idea—it’s a necessary response to the state’s ongoing water challenges.
Examples of residential & institutional water-wise gardens we’ve designed
According to the California Department of Water Resources, the state experiences some form of drought almost every year, with long-term climate models predicting increasingly erratic rainfall patterns and hotter summers.
This puts immense strain on both municipal water supplies and residential landscaping practices.
Traditional turf lawns and water-thirsty ornamentals simply aren’t built for this environment. In fact, a study cited in the EPA's Research Report on Turfgrass Allowance, found that traditional turfgrass landscapes can consume approximately 55.8 gallons of water per square foot per year.
In contrast, a well-designed water-wise garden can reduce outdoor water use by 50 to 70%—without sacrificing beauty.
The Benefits Go Beyond Saving Water
Adopting water-wise gardening techniques offers multiple long-term advantages:
● Lower water bills: Outdoor irrigation accounts for up to 50% of residential water use in California.
● Less maintenance: Native and drought-tolerant plants require less mowing, pruning, and fertilizing.
● Eco-friendly landscaping: Native gardens support biodiversity by providing habitat for local pollinators and birds.
● Fire resilience: Many native plants are naturally fire resistant and/or adapted to fire-prone environments.
● Compliance with evolving regulations: As legislation like AB 1572 moves toward banning nonfunctional turf (in commercial & institutional properties for now, including HOAs), converting to a water-wise garden future-proofs your landscape.
Water-Wise vs. Xeriscaping: What’s the Difference?
Both approaches focus on reducing water use, but water-wise gardening is typically more flexible and aesthetically diverse than xeriscaping, which often emphasizes stark, arid visuals.
Water-wise gardening allows for lush, layered landscapes using regionally adapted plants, vibrant flowers, and creative design elements.
Pro Tip from UC ANR: “Design your water-wise garden to mimic natural plant communities in your region for maximum resilience and minimal upkeep”.

Water-Wise Garden Design Fundamentals: Soil, Planting, and Layering Techniques
Planning a water-wise garden in California starts with design choices. So let’s get into designing your water-wise garden. Good design maximizes water efficiency from the ground up—literally. Therefore, first is the soil preparation.
Soil preparation is key to water retention and a foundation to water-wise gardening. Start by testing your soil texture and drainage through your local UC Cooperative Extension or a DIY jar test.
Incorporate compost or organic mulch to improve water-holding capacity, especially in sandy or clay-heavy soils.
Next, group plants by water needs—a principle called hydrozoning. This allows you to customize irrigation zones and avoid overwatering. Use native species as anchor plants and surround them with companions that thrive in similar moisture conditions.
Layering your garden with tall trees, mid-height shrubs, and low-growing groundcovers improves water efficiency by creating shade and reducing evaporation.
This also mimics the structure of native plant communities– an approach recommended by the California Native Plant Society to support biodiversity, improve root zone hydration, and long-term garden health.

Best Water-Wise Plants for California Gardens
Choosing drought-tolerant plants that thrive in California is central to building a successful water-wise garden. Native plants have evolved to survive dry summers and are typically the best performers.

Even vegetable gardens can be water-wise. Try:
● Tomatoes, peppers, and squash – use mulch to conserve moisture.
● Herbs like rosemary, sage, and thyme – naturally drought-tolerant.

Water-Saving Irrigation Techniques
Smart irrigation systems are the backbone of any water-wise garden.
Drip irrigation delivers water directly to plant roots, minimizing evaporation. When paired with smart controllers that adjust for rainfall and seasonal changes, homeowners can save up to 50% more water compared to traditional sprinklers.
Mulch
Mulch, especially organic mulch like shredded bark or leaf litter, can reduce evaporation by 70%, suppress weeds, and regulate soil temperature. Apply 2–4 inches around plants, keeping a few inches clear of stems.
For extra conservation, consider rainwater harvesting. Rain garden is one of the most effective ways to harvest and reuse rainwater. It is a depression area that is connected to a downspout. When it rains, instead of running off, rainwater will flow into the rain garden, watering plants, growing a habitat for wildlife, and filtering out the pollutants before it goes to underground water. Find out more information about rain garden.
Another way is to use rain barrels or cisterns. They can be installed under downspouts, and swales or rain gardens can capture runoff to irrigate your landscape naturally.
Note: Rainwater harvesting is legal and encouraged in California under the Rainwater Capture Act. If you live outside California, be sure to check your state or local guidelines, as regulations can vary.
