Congratulations 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 Garden for the Senses
What once was a sandy empty lot in the NW has now become a garden that provides food, attracts birds and other pollinators and stimulates the five senses. “The flowers smell great through the seasons, we grow vegetables that we use on our plates,” say homeowners Adam and Meagan Henrie, who like the balance of having aesthetically pleasing and functional areas in the garden.
The Henrie’s accessed online resources, including 505Outside.com, to help decide which plants to incorporate into their garden. During trips to local garden centers, they identified plants that were thriving in their neighborhood. They chose low-maintenance, drought-tolerant plants and installed a drip and spray irrigation system using the latest technology. Local irrigation supply stores helped them choose irrigation system components and come up with a design for the irrigation system that they could follow.
When they planted new trees, they turned to the Water Authority and took advantage of the Treebate from the Water Authority. This rebate program also helps them with costs for tree maintenance.
“We love that our oasis attracts pollinators like birds, bees, butterflies, and also other wildlife like rabbits and roadrunners,” say Meagan.
100’s of Pollinators Can’t be Wrong!
The landscape around Elliott house in the NE used to be a sea of gravel, but now it is recognized by the Fish and Wildlife Backyard Refugee Program. During the past several years, Elliott has spent time transforming his yard into a habitat that attracts insects and wildlife.
“I wanted a yard that will change through the seasons and has a diversity of local drought-tolerant native plants,” he explains. “My goal was to add plants that will attract pollinators, so I started with the ones that were growing in the wild.”
Elliott learned about plants by doing lots of research, including reading information on the Albuquerque Native Plant Society’s website, accessing a list of plants from the Backyard Refugee Program, and visiting the store Plants of the Southwest. His goal was to have a lush, diverse and sustainable landscape that benefits wildlife and does not depend on supplemental water outside of rainwater.
Like the Henrie’s, Elliott has taken advantage of the Water Authority’s Treebate when planting new trees.
“I love all the pollinators, diversity of plants, and my learning journey along the way. Now I get to educate and share my experience with others,” says Elliott, who hopes his yard is an inspiration to his friends and neighbors.
Low Water Paradise
With the goal of reducing water usage, the owners of this home in the Northeast Heights first turned their attention to the property’s big, hardly-used front lawn. Once they learned about the Xeriscape rebate from the Water Authority, they immediately called to get more information and help with choosing plants that would enhance their property.
The transformation started by renting a sod cutter to remove the lawn as part of the Desert Friendly Xeriscape Conversion Rebate. They were able to save the turfgrass and transplant it to their son’s yard.
Landscape professionals were hired to create a design and install the swale, plants, and drip irrigation system. It only took one week to transform the 880-square-foot front yard from a high-water use turf lawn to a desert-friendly xeriscape with a diversity of plants that are supported by rain and drip irrigation.
Because of the transformation, the homeowners earned an $880 credit on their water bill! An extra benefit came when they participated in the Treebate program. Now, the homeowners take pride in their yard, which has attracted pollinators and interest from neighbors. They also are learning how to maintain and care for their new plants so their landscape will continue to bring enjoyment in the years ahead
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.
AfterAfter
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.
The most important part of watering is figuring out how deep you need to water your plants. Once you figure that out, you can easily follow our chart that tells you how often to water.
Here are six simple steps to figuring out your watering depth:
Step 1: Water your landscape for the usual amount of time. If it’s the first time you’re watering, start with the number of minutes found in this Irrigation Advice Chart.
Step 2: Wait 24 hours after watering so the water has a chance to percolate into the soil.
Step 3: Grab a measuring tool, such as an 18” depth screwdriver, soil probe, barbecue skewer or 24” long piece of rebar, and probe your tool into an area you didn’t water to check the soil resistance. Next, go to an area that you watered the day before. Push the probe in until it stops. It should go in fairly easily. Don’t try to push it in further once it stops because you can accidentally break a pipe. Mark the spot it went into with your finger, tape or a permanent marker. Pull out the probe and measure the number of inches. Those inches represent your current watering depth. Using the Seasonal Watering Recommendations chart you can find out the depth you need for your type of plant.
Step 4: Adjust your watering time to correctly determine the watering depth. Did you only water 4” but needed a 12” watering depth? If so, then add more time to your watering schedule and perform the test again. Did you water 24” but only needed 18”? If so, then subtract time from your watering schedule. Water again and wait 24 hours to retest.
Step 5: Once you figure out the amount of time you need to water so the water penetrates to the correct soil depth, you are set.
Step 6: Set your controller for the correct amount of time. Use our handy Seasonal Watering Recommendations chart to see how often you’ll need to water your plants.
Don’t overthink it. Our local, desert-friendly plants (native and adaptive plants typically found in our local nurseries) usually thrive in our native soil.

We are living in a time when our climate is going through rapid changes. Winter days have gotten warmer, and very cold nights are decreasing in number. The decrease in snowpack and early snowmelt that volatilizes before it soaks into the soil are creating drier watersheds, which are vulnerable to fires that can affect our water quality. Reduced snowpack affects streamflow. In order to take care of our Albuquerque landscapes, we need to rely on groundwater. When there’s a lack of precipitation, groundwater recharge is adversely affected. Less precipitation also means drier soils with little reserve moisture to maintain existing vegetation. Even if precipitation amounts don’t diminish, warmer temperatures affect evaporation rates from plant leaves and add to water stress. Supplemental irrigation demand is going to surge to maintain healthy landscapes. We need to implement adaptation strategies, like proper plant selection and smart watering methods, to make climate-ready landscapes a reality in Albuquerque.
We can prepare our landscapes for hotter summer daytime temperatures and warmer winters by following these strategies:
Shade surfaces: Plant trees and large shrubs against walls and near concrete to buffer sunbaked paving and cool walls that absorb heat during the day. By doing this, temperatures can be reduced by five degrees in urban areas.
Plant climate-ready trees: Check out the Climate Ready Tree list. This science-based list of trees that are most likely to survive our changing climate was put together by a diverse group of plant professionals. In mid-century, Albuquerque is projected to become as hot as El Paso, Texas. By the end of this century, our climate will become like present-day Tucson, Arizona.
Mulch everything:Mulchinsulates plant roots from both heat and cold, reducing moisture loss from the soil by evaporation, feeding beneficial soil microorganisms that enhance plant growth and improving soil health. Install 3-4” of mulch over bare dirt to reduce weeds, to enrich the soil and around all new plants to retain the moisture.
Remove or reduce turfgrass lawns: Lawns require 40 inches of water a year, compared with the 8 inches that Albuquerque gets. The greatest value of a cool- season turf is its resilience as a play surface, so if you aren’t regularly using it, consider removing it or installing a low-water grass or meadow.
Incorporate smart irrigation practices: Smart irrigation devices like smart controllers adjust the watering times based on local weather, thus saving water. Drip irrigation delivers water directly to plants. Efficient rotary spray heads reduce water use by 30% or more compared with regular spray heads.
By using these climate-ready practices, it will take less water to create a greener city, support wildlife and keep our community cooler.

One of the biggest obstacles holding homeowners back from removing their high-water turfgrass and installing xeriscape is believing that setting up the irrigation system is difficult. Luckily, it is not as hard as you may think.
If you have an automatic irrigation spray system, you already have an existing valve and, most likely, an AVB backflow preventer. It may look something like this.
Desert Friendly Xeriscape with spray to drip conversion.
The first thing to do before converting to drip is to get the valves checked out by a professional to make sure they are in working order. When you know they’re fine, add a pressure regulator filter combo just past the existing valve and backflow preventer. Then attach ¾”polyline, snaking it around the yard to the new plants and inserting flag emitters at each plant.
The existing underground piping and spray heads are no longer needed. Simply remove all the existing spray heads. There is no need to dig up any existing pipe.
You may have seen the spray-to-drip retrofit kits locally available and wonder if this is a good approach. We don’t recommend this approach because studies show that nearly half of the water saved from converting a lawn to a healthy xeriscape comes from abandoning leaky underground piping and fittings. A Sprinkler system’s lifespan is less than 20 years. If you are not sure how old your system is, or if it is older than 10 years, it’s best to not rely on old underground piping. Since sprinklers typically run for 8-12 minutes and drip often runs for 45-60 minutes, if you have a leak in your old sprinkler piping and it is now part of the drip system you could be wasting a ton of water – negating the savings from getting rid of your thirsty lawn.
Drip irrigation tubing is very inexpensive per foot and only needs to be in a shallow trench. Properly converting to drip irrigation is not as expensive as many people think, while converting your sprinklers to drip the cheap and easy way with a retrofit kit is likely to cost more in the long run.Contact AskAnExpert@abcwua.org to learn more.
