Xeriscaping
Xeriscaping uses drought-tolerant plants and efficient irrigation to conserve water. Learn principles and benefits of xeriscaped landscapes.
Definition
Xeriscaping is a landscaping approach that focuses on water conservation by using drought‑tolerant plants, efficient irrigation, and soil improvements to reduce the need for supplemental watering. Originating in arid regions, xeriscaping incorporates native plants, mulching, and design strategies that minimize water use while creating attractive outdoor spaces. Homeowners benefit from lower water bills, reduced maintenance, and environmentally friendly gardens. Many municipalities encourage xeriscaping through rebates or incentives, especially in areas prone to drought.
Why It Matters
Landscaping is one of the few home improvements that lowers a recurring bill. Swapping turf for drought tolerant beds cuts summer irrigation sharply, which shows up most east of the Cascades where July and August watering drives the whole utility statement. Check the covenants before you dig, though: many HOAs still require a percentage of living ground cover, and rebate programs will not pay for turf you removed before applying.
Examples
A homeowner in Kennewick converts 1,800 square feet of lawn to native shrubs and gravel and watches an August water bill fall from about $190 to about $70.
A Spokane HOA denies a front yard conversion because the CC&Rs require 60 percent living ground cover, so the owner redesigns around low water fescue and sedum rather than rock.
A utility rebate pays $1 per square foot of removed turf but requires photos and an approved plan first, and the homeowner who ripped out the lawn in April collects nothing.
Tips
File the rebate application and get written approval before removing a single square foot, since nearly every program disqualifies work already completed.
Group plants by water need and put each zone on its own irrigation valve, otherwise the thirstiest plant dictates the watering schedule for the entire yard.
Use three to four inches of mulch over amended soil instead of plastic sheeting under rock; sheeting starves the soil and turns the bed into an oven that kills what you planted.
