Steps to Retrofit a Typical Nevada Lawn Into a Drought Garden
Nevada is a place of dramatic landscapes and limited water. Converting a conventional, water-hungry lawn into a drought-tolerant garden lowers water use, reduces maintenance, and creates a landscape more in tune with regional climate. This guide walks through practical, step-by-step actions — from site assessment to plant selection, irrigation design, installation, and maintenance — with concrete measurements, techniques, and decisions you can apply to a typical yard in Nevada.
Why Retrofit? Nevada Climate and Water Realities
Nevada’s climate ranges from high desert to Mojave lowlands. Annual precipitation is low, summers are hot, and evaporation rates are high. Municipal water utilities and local conservation programs encourage reducing outdoor water use because lawns are often the largest single consumer of household water in arid regions.
Retrofits deliver multiple benefits:
-
Reduce water bills and irrigation demand.
-
Lower maintenance time and costs.
-
Improve biodiversity and habitat for pollinators.
-
Comply with local water restrictions and qualify for rebate programs.
Regional Differences: Northern vs Southern Nevada
Northern Nevada (higher elevation, cold winters) can support different plants and may have a shorter growing season and colder soil temperatures. Southern Nevada (Las Vegas area, Mojave Desert) faces higher summer heat and lower rainfall, so choose plants that tolerate extreme summer heat. Microclimates within your property (shade from buildings, north-facing slopes, reflective heat pockets) also matter.
Step 1: Survey, Goals, and Regulations
A successful retrofit starts with a clear assessment and goals. Take time to map and document the site.
Inventory and site analysis
-
Note sun exposure by the hour (full sun, partial shade, full shade).
-
Identify slope and drainage: does water run off quickly or pool?
-
Map existing irrigation lines, valves, and backflow devices.
-
Check soil type by digging small test pits in several locations: sandy, loamy, or clayey; watch for caliche or hardpan layers.
-
Record mature height/width of plants you want to keep.
HOA, municipality, and permit issues
-
Verify homeowner association design rules before removing turf or changing front-yard appearance.
-
Check city/county requirements for irrigation backflow prevention, greywater, and rain-harvesting systems.
-
Ask your local water utility about rebate programs for turf removal and smart irrigation controllers.
Step 2: Design Principles for Drought Gardens
Design with water-efficiency, aesthetics, and function in mind. Key principles:
-
Group plants by water needs (hydrozoning) so each irrigation zone serves similar species.
-
Use native and well-adapted plants to minimize supplemental water once established.
-
Favor permeable hardscape to allow infiltration and reduce runoff.
-
Provide deep, infrequent irrigation to encourage deep rooting.
-
Reserve small irrigated areas for edible gardens or social spaces.
-
Start with a base plan showing zones: low-water (xeric) turf alternatives, shrub beds, tree placements for summer shade, and pathways.
Plant selection strategies
Choose plants with different roles: structural trees, mid-layer shrubs, low groundcovers, and accent succulents. Examples of categories and typical choices for Nevada climates:
-
Trees for shade and vertical structure: desert willow, native mountain mahogany, palo verde (in southern regions).
-
Shrubs and perennials: sage species, Artemisia, Penstemon, Salvia species, Russian sage, rabbitbrush.
-
Succulents and agaves: Agave species, yucca, Hesperaloe (red yucca).
-
Groundcovers and grasses: native bunchgrasses, low sage, kurapia alternatives or native alternatives instead of high-water lawn.
-
Seasonal color: desert marigold, penstemon, lupine (where appropriate).
Avoid overplanting densely; give plants room to mature to reduce long-term pruning and replacement.
Step 3: Removing Turf and Preparing Soil
Removing grass is one of the most labor-intensive parts of the retrofit. Choose a method based on scale, budget, and timeline.
-
Mechanical removal: Rent a sod cutter to slice and roll turf. This leaves soil ready for replanting and reduces weed seed incorporation.
-
Solarization: Cover lawn with clear plastic for 6-8 weeks in summer to kill turf and weeds in place. Works well in high heat regions but requires time.
-
Sheet-mulching: Layer cardboard or thick paper over turf, cover with several inches of compost and mulch. This kills grass and builds soil but takes weeks to months.
-
Herbicide: Chemical turf removal is effective but must be used carefully and in accordance with label instructions and local rules.
Soil preparation after removal:
-
Perform a soil test (pH and basic nutrients). Nevada soils often run alkaline and may contain salts or caliche. Soil test helps decide amendments.
-
For topsoil improvement, incorporate 2-3 inches of compost across planting areas and cultivate to 4-6 inches depth. Do not overdo organic matter in desert soils; aim to improve structure while preserving native drainage.
-
If caliche or hardpan is present, excavate planting pockets or amend with coarse material and compost to encourage root penetration.
-
Correct pH slowly: elemental sulfur lowers pH over time; gypsum helps sodic soils but will not lower pH.
Step 4: Irrigation Strategy and Installation
Efficient irrigation is critical. Replace pop-up lawn sprinklers with microirrigation (drip) or low-flow bubblers for planting areas, and resist using sprinklers for non-turf beds.
-
Group plants by water need into irrigation zones: high, moderate, low.
-
Use low-pressure drip tubing or 1/4-inch microtubing with emitters. Typical emitters are 0.5, 1, 2, or 4 gallons per hour (gph).
-
Use pressure regulators and a filter on the main line to protect emitters.
-
Install a backflow preventer as required by code.
-
Consider a smart controller that adjusts schedules based on local evapotranspiration or weather inputs.
Practical emitter layout examples:
-
Shrub and perennial beds: use 1 gph emitters spaced 12-18 inches along a 1/2-inch drip line. Adjust spacing to soil type (wider spacing in clay, tighter in sand).
-
Trees: place two to four 2 gph emitters outside the rootball near the dripline to encourage lateral root growth. For larger trees add more emitters or use a drip ring.
-
Groundcovers or dense plantings: use 0.5-1 gph emitters every 12 inches or a dripline with built-in emitters.
Irrigation scheduling guidelines:
-
New transplants: water deeply at planting, then for the first few weeks water more frequently for establishment, slowly lengthening intervals.
-
Established xeric shrubs: deep soak once every 2-4 weeks in summer depending on heat and plant type; reduce in cooler months.
-
Trees benefit from deep, infrequent irrigation to 12-18 inches of soil moisture. Use a soil probe or moisture meter to verify wetting depth.
Example math for run times:
- If a shrub requires 8 gallons to wet its root zone and you use two 2 gph emitters (4 gph total), run time = 8 gallons / 4 gph = 2 hours per irrigation event.
Step 5: Planting and Mulching
Correct planting technique and mulching maximize survival and minimize water use over time.
-
Planting depth: set the root ball so the top of the root flare is at or slightly above the finished soil surface. Do not bury stems.
-
Loosen circling roots; score or tease root mass to encourage outward growth.
-
Backfill with native soil amended with a modest amount of compost (up to 20 percent by volume). Avoid creating a deep pocket of uncompacted fluffy material where roots can sit.
-
Water in slowly after planting to settle soil and eliminate air pockets. Form a shallow basin to direct water to the root zone.
Mulching:
-
Organic mulches (wood chips, bark) at 2-3 inches depth reduce evaporation, moderate soil temperature, and suppress weeds.
-
Leave a clearance of 2-3 inches between mulch and plant stems to prevent rot and pest hiding places.
-
Inorganic mulches (decomposed granite, gravel) can be used for decorative areas; keep depth to 1-2 inches and consider a weed-barrier fabric only where necessary.
Water-wise Maintenance and Pruning
A drought garden is low-maintenance, not no-maintenance.
-
Inspect irrigation lines for leaks and emitter clogs seasonally.
-
Adjust controllers seasonally and after storms; reduce runtimes in winter.
-
Renew organic mulch annually and top-dress planting areas every 1-3 years.
-
Prune to maintain plant structure and remove dead wood; prune at appropriate times for each species.
-
Fertilize sparingly; many drought-tolerant plants do not require heavy feeding. Use slow-release, low-nitrogen formulas only where deficiency is evident.
-
Monitor for pests and disease and use targeted, least-toxic controls where possible.
Step 6: Hardscape, Permeability, and Rain Harvesting
Incorporate hardscape elements that reduce heat and increase function.
-
Use permeable pavers or gravel paths to maintain infiltration.
-
Consider dry creek beds or swales to manage runoff and direct roof water to planting basins.
-
Rainwater harvesting: install rain barrels or tanks to capture roof runoff for landscape irrigation. Verify local regulations for storage and connection to irrigation systems.
-
Greywater systems can irrigate subsurface plantings in some jurisdictions; follow local code and best practices.
Budget, Timeline, and Common Pitfalls
Budget and timing vary with yard size and choices. Rough ranges:
-
DIY turf removal and basic soil prep: $0.50 to $2.00 per square foot for equipment rental and disposal.
-
Professional turf removal and disposal: $1 to $4 per square foot.
-
Drip irrigation materials: $200 to $600 for an average yard DIY, more for larger and more complex systems.
-
Plant costs: $8 to $50+ per plant depending on size and species. Trees and larger shrubs cost more.
-
Hardscape, mulch, and labor can add several thousand dollars if professionally installed.
Timeline:
