With drought conditions predicted to continue for the foreseeable future, we’re likely to water more often this spring and summer. Make every drop count – and keep us on track to meet our conservation goals – by performing routine maintenance to maximize your sprinkler system’s efficiency.
Monthly
Check for leaks by inspecting water lines, sprinklers, emitters, and other components. Look for wet spots in the landscape and listen for hissing to help locate issues.
Your irrigation system is only as good as its aim. Adjust sprinklers and emitters to make sure they’re delivering water to the landscape and not onto rocks, bare earth, or pavement.
Replace damaged parts immediately with identical or equivalent parts. This ensures uniform coverage and optimal system efficiency.
Locate and clean any clogged equipment.
Use water meter and historical data to help reveal hidden leaks.
Check to make sure irrigation controller is set appropriately for the season
Spring
As the watering season gets underway, check your irrigation system for leaks and clogged, broken, or missing sprinkler heads and emitters.
An outdated irrigation system can waste time, water, and money. Consider installing a new WaterSense-labeled, “smart” irrigation controller to take the guesswork out of scheduling (rebates available).
Set the controller for watering frequency, start times, and duration per zone per program.
Replace the back-up battery in the controller.
Test the manual shut-off or isolation valve.
Check the water pressure in each irrigation zone.
Check and clean filters, wherever they are in the system.
Check and clean the filter screen in each sprinkler body. Adjust the rotor arc or spray pattern to eliminate water waste.
Test heads to make sure they are delivering consistently and efficiently.
Inspect all drip emitters (look for wet zones after running a complete cycle). Unclog or replace any that are malfunctioning.
Early Summer
Adjust controller for the appropriate seasonal setting.
Adjust sprinklers and emitters to make sure they’re delivering water to the landscape and not onto rocks, bare earth, or pavement.
Check and clean filters, wherever they are in the system.
Inspect all drip emitters (look for wet zones after running a complete cycle). Unclog or replace any that are malfunctioning.
As plants grow bigger, move the emitters to the edge of each plant’s root ball or drip line to encourage further root development.
Fall
Adjust controller for the appropriate seasonal setting.
Test the manual shut-off or isolation valve.
Check and clean filters, wherever they are in the system.
Inspect all drip emitters (look for wet zones after running a complete cycle). Unclog or replace any that are malfunctioning.
Winter
Guard your irrigation system against freezing temperatures by draining pipes and tubing and properly winterizing your system.
When temperatures are below 40 degrees Fahrenheit, discontinue automatic watering and turn on systems manually or hand water as needed.
In an arid city like Albuquerque, trees and the urban forest are even more important than in places with more moisture. Trees provide shade and habitat, and help cool the urban landscape. To sustain a healthy canopy trees require special care given the arid climate, ongoing drought, and warming temperatures. This year’s hot, dry conditions highlight the need for New Mexicans to take even more care of their trees – and to plan for which species will grow best in increasingly warm conditions. This was especially true this past September when a windstorm wreaked havoc on trees throughout the city.
In collaboration with Our Land New Mexico, a local environmental show on NMPBS, we are sharing a short (7 minute) episode they did about the urban forest in Albuquerque.
The episode discusses how the vitality of a city can be measured in part by the health of its trees and plant life. There is also evidence that tells us how exposure to nature provides emotional and social benefits, lowers stress levels and encourages more community engagement in residential settings.
We encourage you to take care of your trees to support our urban forest and if you are adding a new tree email AskAnExpert@abcwua.org with questions. Local tree experts around the Southwest, including conservation staff from the Water Authority, with the guidance of the Nature Conservancy, have put together a climate-ready tree list that includes trees that will thrive in our current and future climate.

September days can have widely varying temperatures, with some days getting into the 90s, but we can count on nights being longer and cooler. This means that plants do not need to be watered as often. Ramping down how often you water your yard is a great way to save money on your water bill and keep plants happy.
After spending the summer putting energy into growing leaves, flowers, and fruit, plants use the fall to store water and energy in their roots for winter survival and spring growth. Proper watering supports this activity.
Ramping down your irrigation does not mean you should stop watering altogether. If you have a lawn, cut back to two days per week. Cut back to two times a month for mature trees (4 times a month for younger trees).
Water Authority customers have been inspired to convert their turf to sustainable, resilient xeriscapes that save water, time and money and provide habitat for wildlife and pollinators for many reasons. Below are some of our favorites:
“We just didn’t see the point of maintaining and paying to water the grass in the front yard. No matter how much we water and fertilize, the front lawn never looks good, and we don’t want to be the last house on the block with a not-so-great lawn.”
“Now that the kids are out of the house and we no longer have dogs, we don’t want to have such a high water-use landscape that requires weekly maintenance. We want to do our part in saving water for future generations and create a beautiful patch of nature in our backyard, especially now that we’re into birdwatching.”
“We may downsize someday, and our realtor said that having a beautiful low water use landscape is a good selling point.”
“We just moved to Albuquerque from another part of the country where grass grows easily, and we spent several hours a week mowing and weeding. We are done with mowing. We want a landscape that is regionally appropriate, with native and low water use plants and trees.”
“Our irrigation system seems to always need repair, and the grass never really looks that great.”
“We needed to replace our sewer line which meant digging up the front yard. It seemed like a good time to ditch the grass and convert it to a low maintenance landscape with new drip irrigation.”
Qualifying conversion projects by Water Authority residential customers may receive $1.00 per square foot of converted turf grass. This rebate has a specific application process. Only projects that have completed the application and passed inspections will qualify for the rebate. For more information visit our rebates page.
Pro Tip: Are you ready to convert your lawn to a xeriscape? Here is what local landscape contractor Tyson Hafler, owner of Southwest Horticulture, wants you to know before you start.
“Make sure you start with a green lawn. It is important to have a green lawn for two reasons. Water Authority needs to see a currently cared for, in good living condition green lawn to quality for the rebate. A live, green lawn is much easier and speedier to get rid of than a brown, dry, dead and dying lawn.”

Our urban forest (yes, the trees in your landscape are part of a forest) provides so many benefits too us – cooling, increased home values, beauty, and better mental health just to name a few.
Here’s what you can do to help keep your members of our urban forest as healthy as possible.
1. Water your trees to a depth of about two feet, because 95% of the tree’s roots are in the first two feet of soil. To check if you are getting down to that two-foot optimum, insert a long screwdriver or soil probe into the soil around your tree a day after watering to determine the depth the water has reached. Adjust your watering time, if needed, to reach that two-foot goal.
2. Water your trees a little inside and outside of the canopy edge (the outer ring of the tree’s leaves) because that is where the roots that take in water are located.
4. Check your trees for signs that they aren’t getting enough water: wilted leaves early in the morning, scorched leaf edges, twig die-back from the top down or a sparse leaf canopy.
5. Take advantage of rainwater by directing downspouts or canales toward existing trees. Consider planting new trees in lower areas to take advantage of captured moisture.
6. Surround your trees with 4-6 inches of organic mulch. Organic mulch helps to retain soil moisture, keeps soil temperatures more consistent, and keeps weeds out. Additionally, over time it loosens compacted soil, adds organic matter, and slowly adds nutrients to the soil. Note: organic mulch does not include bark (sometimes called ‘bark nuggets’ or ‘deco bark”). Use actual wood chips like what comes out of an arborist’s woodchipper. Many tree services offer wood chips for free and several local businesses sell wood chip mulches in bulk.

The amount of water needed and where that water should be applied changes as woody plants (such as trees, shrubs and vines) get larger. Woody plant material has two types of roots, stabilizing roots and feeder roots. Both types of roots do just what their name implies. Stabilizing roots are thick and dense to keep the plant in place and support its weight. Feeder roots are super fine and grow more like a net to take in water and nutrients. Feeder roots expand out as the plant grows.
Some woody plants require more water as they mature, but more desert-friendly species may not require extra water or may even be able to survive without supplemental irrigation once established. Perennials normally do not need to have expanded watering the same way woody plants do as they mature.
Some examples of this:
Plant Type
Plant
1st summer
2nd summer
3rd summer
Tree
Desert Willow (Chilopsis linearis)
60 gallon per month
120 gallons per month
400 gallons per month
Shrub
Butterfly Bush (Buddleia davidii)
60 gallon per month
70 gallon per month
100 gallon per month
Desert-Friendly Shrub
Chamisa (Ericameria nauseosa)
20-30 gallons per month
20-30 gallons per month
Usually possible to remove from irrigation
Vine
Trumpet Vine (Campsis radicans)
40 gallons per month
60 gallons per month
100 gallons per month
Woody Groundcover
Prostrate Sumac (Rhus trilobata)
20-30 gallons per month
40 gallons per month
60 gallons per month
For those plants that do have increased irrigation needs as they mature here are three easy ways to apply the right amount of water in the right place depending on the type of irrigation you are using.
Drip Emitters – Move the drip emitters out to stay in line with the outer edge of the plants leaves where the feeder roots will be. Increase the number of emitters watering the plant too, placing them evenly around the outer perimeter of the plant.
Netafim (in-line professional drip line) – this is typically installed in rings around the plant and additional rings can be added as the plant grows larger. Netafim can also be laid out in a grid pattern, particularly when being installed around an already established plant.
Hand-watering – Build and maintain a watering well at the outer edge of the plant perimeter. As the plant grows, increase the size of the well.
