In our changing climate, water is becoming a precious resource. For many communities, municipal water restrictions are now commonplace, requiring innovative approaches to landscaping and gardening. One solution is xeriscaping, derived from the Greek word for “dry,” which employs drought resistant plants and water conservation measures to limit the use of irrigation in landscaping.

Xeriscapes do not follow a specific design but apply a set of principles to determine the most efficient and pleasing layout based on the climate and topography.

    Planning and Design

    In order to work in harmony with the natural features of the land, a detailed plan is essential. A xeriscape plan differs from traditional landscaping plans in that it attempts to adapt to the existing features and climate, rather than forcing change through watering or amending.

    Start by making a scale drawing of your yard and its existing features. Be sure to include your house, driveways, walkways, patios, trees, planting beds, spigots, downspouts, buried cables and drains. Take note of the slope of the land, sunlight and shade, and which areas tend to be wet, dry, windy, hot, humid, or cool.

    The next step is deciding how you want to use your yard. Pencil in any new features, such as a vegetable garden, an area for pets, or a shady spot for relaxing. The final step is determining which types of plants are best suited for each area and how they will receive water.

    Improve Soil

    If you are using only native plants, soil amendments may be unnecessary, and some plants actually thrive in poor soils. For most plants, however, a nutrient-rich, well-drained soil is essential to hold in moisture without drowning the plants. For flower beds, work 1 to 2 inches of compost into 6” or more of soil. Deeper planting holes for trees and shrubs should have compost or organic matter added as well. If your soil is particularly compact with clay, consider a drainage amendment such as Perma Till.

    Minimize Grass

    Rethink the concept of a traditional “lawn” since traditional turf grass requires a lot of water. Limit grass to walking and play areas, and consider the use of mulched or naturalized areas, along with patios and walkways, as alternatives. Do not plant grass where grass does not like to grow! Choose drought-tolerant grass suitable for your climate—such as zoysia, Bermuda, or buffalo grass—and plant during rainy seasons to minimize watering.

    Choosing Plants

    Using plants native to your area reduces the need for fertilizer, soil amendments, and irrigation. Xeriscaping uses the principle of “plant zoning,” in which plants are grouped according to water, light, and soil needs. This minimizes water waste and makes maintenance much easier. If you love certain plants that require lots of water, group them together close to a water source such as a drainage area or downspouts to make use of rainwater runoff.

    As much as possible, choose plants that are drought and heat tolerant, particularly for dry sunny areas. Instead of irrigating an entire bed, tuck in containers for a splash of color, and water them by hand.

    Mulch

    Using a layer of mulch around plants increases moisture retention and helps keep roots cool. See Using Mulch in Your Garden.

    Watering

    If there are areas that require extra irrigation, install drip systems or soaker hoses that conserve water by targeting specific plants. Avoid sprayer-type irrigation systems that waste water through evaporation and misting. Install water collection systems, such as rain barrels, close to plantings with higher water needs. Water after 9 p.m. and before 9 a.m. to reduce evaporation. Water less frequently but more deeply to encourage stronger roots that can withstand drought.

    Maintenance

    Xeriscapes require less maintenance than traditional gardens, because the detailed planning ensures that each plant will be naturally suited to the area. Nevertheless, routine weeding, pruning, irrigating, and fertilizing (if needed) are necessary to keep plants healthy and to reduce competition for nutrients and moisture.

    Xeriscaping Tips

      • Check your local ordinances to find out if there are any restrictions on watering or turf installation. Some communities change the water restrictions throughout the season, depending on rainfall and temperatures.
      • Research your area’s annual natural rainfall, particularly in recent years, so that you can choose plants with similar water needs.
      • Research your region’s native plants – they will be naturally well-adapted to your climate and soil. Check with your local agricultural extension service for a list of plants native to your area.
      • Dig a few “test” holes to get a sense of the soil makeup of your yard. You’d be surprised how it can vary over a relatively small area.
      • Have your soil analyzed to determine needed soil amendments and to place plants according to soil requirements. Again, your local agricultural extension service is a great resource. Soil analysis will tell you the pH value, current levels of major nutrients, and recommendations for soil amendment.
    • Redefine how you interact with your patch of earth. Rather than trying to conquer or rehabilitate problem areas, work with the land’s natural habits to create a low-maintenance landscape that thrives on its own resources.
