In these long, hot days of summer, especially if the summer rains don’t come, many plants really suffer from a lack of water. By incorporating native and very adapted plants into the landscape, we can still have attractive landscapes that don’t require a lot of irrigation, maybe even none in a good year!
These native plants are sometimes referred to as “luxury consumers." Their evolution, in an arid climate that occasionally has wetter years, has given them the ability to subsist reasonably well on low water. When there is an abundance of water, they take advantage of it and really grow. This kind of luxury growth may happen only every few years. In really dry years, they will lose some outer canopy. This adaptability helps them survive and even thrive in our natural landscape.
Among the plants that fit into this category are trees, shrubs, and native grasses: desert willow, Apache plume, three-leaf sumac, four-wing saltbush, chamisa, turpentine bush, and Mexican thread grass. There are others of a similar nature; native plants that really don’t need regular abundant water. Cactus is another type of plant that is easily over-watered. You might even end up killing it with too much water, as its roots rot away in constantly moist soil. If cacti don’t die, they may end up taking over a space.
One of the great aspects of xeric plants is that they are low maintenance. Small trees and shrubs live happily for years without needing pruning. Single stands of attractive, waving silky-looking grass seed heads don’t become a billowing menace when they quickly spread beyond the designed zone.
These plants should be irrigated regularly the year of planting but should be weaned to a lean water budget before they get too used to luxury living. A luxury level of irrigation should be saved for fruit trees and shade trees — plants that actually need that amount of water and produce fruit and shade.
To help save water, look for water harvesting opportunities in your landscape, especially when deciding where to plant. Where does water come off the roof, and where does it go on the ground? If you can redirect that roof water to a high spot that will flow into the yard — and maybe even contour the yard in shallow, subtle ways to get that water to spread out and slow down and sink in — then you can take advantage of the water by planting strategically along the flow line.
Mulches are a great water-saving step for native trees and shrubs. Rock is too hot for most things, except for ocotillo and some cacti, so use coarse chipped tree waste. Some local tree companies offer free mulch. Keep sunlight off bare ground around the plants and you will slow down evaporation from the soil while reducing the ambient air temperature enough to make a difference to the plants living out there all day, every day.
As far as shearing goes, this kind of pruning creates very tight outer canopies with lots of leaves (the resulting growth that follows previous cutting), usually in a simple geometric shape. Native plants that have less dense outer canopies end up having a higher water budget due to the excess foliage grown by shearing the canopy. A natural form could have the same overall size but with a more open, interesting branching framework supporting a more natural leaf density, and all of that on less water. It’s best to let the plant’s nature express itself through the form it grows without a lot of interference and to prune strategically to highlight well-placed branch systems and balanced mass.
Congrats to the ten winners of our first annual Water Authority Desert Friendly Landscape Contest! Thank you for sharing your beautiful gardens with us. They will be an inspiration for others to make the switch to desert-friendly landscapes.
A transformation from an unhealthy-looking, high-water use turfscape to a colorful xeriscape medley.
Before
This family was ready to change out their high-water and high-maintenance front lawn grass to a desert-friendly landscape. Their new low-water and low-maintenance yard features 94 desert-friendly xeriscape plants. They worked with a professional company on the design, to remove the sod and to install the drip system and new plants. Plants were selected from the Xeriscape Guide provided by their contractor.
After
By transforming their yard to a xeriscape, they were able to save a total of 156,000 gallons of water within the first year and get a $1,300 rebate from the Water Authority for the conversion. They saved even more money because the contractor was able to reuse existing irrigation valves to convert the spray to a drip system. The best part, they say is “the variety of colors from the plants and the birds and butterflies the landscape attracts”. They also receive many compliments from neighbors and friends, which makes them feel proud.

Talk about creating a diverse and lush yard! This desert-friendly landscape has all the right elements.
As a retired landscape architect Richard Bumstead had the pleasure of designing and installing his own landscape during the beginning of the pandemic. Like many Albuquerque yards, his front yard located in the center of the city was covered with junipers and gravel. Removing them opened up a large area, creating a blank slate and the opportunity to diversify his landscape. Having spent most of his career in Chicago, Richard was not very familiar with the local plants. He read many New Mexico plant books, including Judith Phillips, “Growing the Southwest Garden” and the “Down to Earth” guide from Albuquerque Master Gardeners. The staff at Plants of the Southwest and Jericho were also a big help as he prepared his landscape plan. His visible front yard is now full of native pollinator plants along with three trees that are local favorites: Pinon Pine, Desert Willow and New Mexico Locust.
Richard waters his established plants once a month in the winter and only once a week during the irrigation season. He says the key to having a good-looking landscape is to prepare the soil and water plants to the right depth.
Since he has a more protected backyard, Richard was able to add many shade-loving plants as well as foraging plants like strawberries, rhubarb, tomatoes, an apricot tree and a variety of herbs. Find his extensive plant list here.

From Bermuda Grassland to a Desert Friendly Landscape!
Geri Martinez’s property, which is located in one of the older areas of town surrounded by large established trees, had the kind of yard that’s typically found in Albuquerque’s UNM and Ridgecrest neighborhoods. It was covered in Bermuda grass and had a large mulberry tree. Geri was ready to refresh the front yard of her 60+ year-old home. With the help of a landscape designer, she came up with a planting design plan.
After
Geri, an avid DIY’er, installed her own plants and irrigation system. To help her figure out what to plant and how to set up the irrigation system, she read local publications from nurseries, attended workshops and used a professional landscape design to determine plants locations.
Geri loves sitting outside and watching the birds and bees that are attracted to her landscape. Saving water has been her goal. She’s not only reduced her front yard water use but also the amount of water she uses indoors. She has low-flow fixtures inside the home and utilizes rain barrels to supplement her landscape’s irrigation during the rainy season. Geri is proud to have a visually-appealing landscape that conserves water.
This low-growing native shrub is an excellent choice for compact spaces in the desert- friendly garden. The texture of its soft fern-like leaves contrasts well against desert accent plants. Dark green leaves are covered with an abundance of small purple flowers in late summer through early fall. A native to the Chihuahuan desert, it is much beloved by native pollinators. Minimum maintenance is required — just an occasional trim at the edges if it starts to get leggy. Plant in well-drained areas and avoid overwatering.
This spectacular native wildflower is everblooming with a profusion of large, bright yellow, four-petaled flowers. Its narrow gray-green foliage gives the plant a lacy look in the garden. Calylophus thrives in the heat and grows well in a wide range of soils, as long as they’re well drained. This tough plant is the star of any dryland rock garden or xeriscape. Giving it a good shearing before the growing season starts in late spring will keep it looking tidy and loaded with flowers.
