Xeriscaping Doesn't Mean ZERO Scaping

Xeriscape is a landscape design emphasizing little to no water usage and is a realistic alternative to traditional landscaping in any climate. Low water use landscaping does not mean one is limited to cacti, succulents, and rocks. Instead, it involves designing a landscape that utilizes low-water plants and reduces turf. Other benefits of xeriscape include reduced yard maintenance and reduced water bills while attracting wildlife to your yard. 

The most vital part of your xeriscape plan is ensuring that watering and irrigation zones are laid out efficiently. A successful xeriscape relies on minimized water usage through efficient irrigation methods. A drip system can deliver water directly to a plant’s roots deep within the soil, reducing evaporation and allowing us to water with less frequency.   

Turf uses large amounts of water. By limiting, or eliminating, turf in your landscape planning, you can significantly cut down on water usage. Turf areas will be irrigated differently than border areas containing flowers and shrubs. Flowers and shrubs can utilize a drip system using less water while turf requires irrigation or sprinkling using significantly more water. 

Now it is time to decide where to place everything, choose low water usage plants, shrubs, and trees. Drought-tolerant species can withstand Idaho’s dry conditions. Arrange plants with similar water requirements together. Some recommendations for drought-tolerant plants include Sagebrush (Artemisia tridentata) and Penstemon. Wavy-leaf oak and Mountain Mahogany are examples of drought-tolerant trees. Make choices that will provide pops of color in your yard throughout the year.

Before planting, you must enhance the soil quality to retain moisture. Soils in the Treasure Valley tend to be heavy with clay. Add organic matter, compost, and mulch to improve the soil and enhance water retention. The use of mulch can also aid in weed abatement. Plastic and other non-porous materials are not recommended for use in the garden for keeping down weeds.

Finally, you may also want to add rocks and boulders for visual interest. Often, rocks are arranged in such a way that it appears there is a dry stream bed running through the yard.

Regularly maintain your xeriscape by pruning, weeding, and adjusting irrigation as needed. Watering early in the morning reduces the amount of water lost to evaporation. Early morning irrigating also reduces the risk of disease because plants have time to dry out during the day.
