Smart technology has become popular at homes and businesses because it makes some aspects of daily life easier and more efficient. WaterSense Smart Irrigation Controllers are the Water Authority conservation group’s favorite smart technology.
These types of controllers adjust landscape irrigation schedules using weather data, plant type, soil type and other important factors to help you follow the seasonal watering recommendations.
Pro tip: “One of the advantages of Smart Controllers is that they help the user make good watering decisions during the set up process to ensure a healthy landscape throughout the year,” says Ken Schwartz, branch manager for Neumark Irrigation Supply.
Installing a WaterSense-labeled controller provides the following benefits:
A healthy, beautiful landscape: WaterSense-labeled controllers help landscapes flourish and remain healthy by providing the right amount of water for each plant zone. Underwatered or overwatered landscapes can be unhealthy and unattractive.
Water quality protection: These irrigation controllers reduce water runoff from the landscape, helping to keep local water bodies clean and healthy while avoiding water waste.
Savings of both water and money: WaterSense-labeled controllers help eliminate overwatering, so they may lower water-use expenses and conserve water
Convenience: Properly programmed WaterSense-labeled controllers save end-users the time required to continuously monitor and adjust irrigation schedules in response to changing weather.
Many of these controllers are compatible with mobile devices like tablets and smartphones to allow the user to interact with their irrigation system remotely. The Irrigation Association has assembled a list of smartphone-friendly irrigation controllers. You can find many of these controllers at your local irrigation supply store.
The Water Authority offers residential rebates of 25% up to $100, and commercial rebates of 25% up to $500, for WaterSense Smart Controllers. The rebate can be used for both purchase of the controller and the cost of professional installation. Before purchasing your new controller, make sure to visit the list of qualified WaterSense controllers located in the rebate section.
Look for the WaterSense logo when purchasing your new controller.

Your irrigation system is only as good as its aim. Adjust sprinklers and emitters to make sure they are delivering water to the landscape and not onto rocks, bare earth or pavement.
June is a great time to check and replace any clogged spray nozzles or drip emitters. Remember, each spray head also has its own filter insert that needs checked as well.
Watering Recommendations: Summer is here and so are hotter temperatures! Follow the Water by the Seasons Summer watering recommendations to keep your yard looking healthy. For turf, water 2-3 times per week. Start watering your trees and shrubs 1 time per week to keep them looking good.
Remember, if it rains more than a half inch you can skip your next scheduled watering as there is no need for supplemental irrigation.
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

1st summer
2nd summer
3rd summer
Tree
Desert Willow (Chilopsis linearis)
60 gallon per month
120 gallons per month
400 gallons per month

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.

Service: April’s freeze
may have damaged your irrigation system, so make sure to inspect it for leaks,
or broken sprinkler heads and emitters!
Watering Recommendations: Spring rains are benefitting established landscapes! Follow these watering recommendations to keep your yard looking healthy: for grass (turf), water one-two times per week and for your trees water one-two times per month. To know how much to water, follow our Water by the Seasons spring watering recommendations. Remember, if it rains more than a half inch you can skip your next scheduled watering time as there is no need for supplemental irrigation.
Trees are incredibly valuable and provide a wide array of
benefits, from increasing home values to improving mental health.
Unfortunately, Albuquerque has suffered large losses of trees in the past
decade. It’s more important now than ever to take care of your existing trees.
A common sight on spring evenings is seeing people with
their thumb on the hose, spraying the trunk of a tree. While it’s great to see
people caring for their trees, there is a better way to water them.
Trees have several different types of roots that serve different functions. Fine hair feeder roots are responsible for taking up water. Because these feeder roots are generally located near the tree’s canopy edge, this is where you want to apply water: a little inside and a little outside of the canopy edge.
TREE WATERING TIPS:
1. Hand watering
Turn your hose to a low flow or fast drip, so the water soaks into the soil before running off (try a hose end shut off valve). Set a timer and move the hose to different locations every 20 minutes starting 5 feet from the trunk to just outside the canopy edge. Small to medium trees will require watering at between 12 and 20 locations. Larger trees may need to be watered in sections over a few days.
2. Drip irrigation on desert friendly xeriscape
Growing healthy trees in a desert friendly xeriscape is possible using drip irrigation such as flag emitters. As trees grow, they require more resources in the form of soil rooting space and water. That means that as trees become established, drip irrigation emitters need to be shifted away from the original rootball (at the time of planting) out to the edge of the tree’s canopy. Additionally, the number and size (volume) of emitters needs to be increased as the tree grows. Most people don’t make these adjustments. Consider these strategies instead:
Plant an understory of groundcovers or flowering perennials within and beyond the tree’s canopy. The emitters used to water the groundcover plants will, in turn, water the tree. As the tree becomes larger it may eventually shade out the groundcovers, but the emitters should be kept in place to continue watering the tree.
Consider supplemental watering by hand in dry areas of your yard that are not covered by the drip irrigation system.
A similar strategy is to use professional landscape drip line (often referred to as netafim) in a grid or spirals in and outside of the tree’s canopy. This irrigation material requires less frequent maintenance and can be installed under mulch. As the tree matures, the drip line can be expanded and shifted to support the increasing needs of the tree. Understory plantings can also be used with this type of irrigation material.
3. Using sprinkler irrigation to water trees in a grass lawn
Most lawns in our area require nearly 40 inches of yearly irrigation to look good. So, it makes sense to plant a tree in the lawn to take advantage of all that water. Most of the large, beneficial trees in our city parks are grown like this. However, some species (like cottonwoods) respond to the shallow and frequent lawn irrigation by making shallow roots that protrude above the surface. These surface roots create tripping hazards. Damage to the tree can result from lawn mowers, too. Shallow roots also make the tree more susceptible to drought stress. Encourage tree roots to go deeper by occasionally (one-two times per month) running the lawn sprinklers for three or more cycles for a longer period. This will help to get water down deep, where it will remain in the soil longer and encourage roots to move deeper. Occasional deep watering in lawns also has the added benefit of flushing out salts accumulated from hard water and fertilizer.

Do you want to walk barefoot across cool, soft grass? Especially on those hot summer days? We’d love for you to do that! We also want you to take care of your lawn in a healthy way that saves the most water.
One might assume that proper lawn care begins in the spring
but creating that beautiful lawn can start at any time. Sometimes it’s even better
to start in the fall. Either way, you need to begin with good soil, full of
organic material that will both provide nutrition and help hold in that
moisture. But if you don’t already have that, how do you get it?
First, dethatch your lawnonce a year. Most lawns need this done when the layer of thatch reaches roughly ½” thick. Cool season grasses, such as bluegrass, need to be dethatched in the fall, whereas warm season grasses, such as Bermudagrass, need to be dethatched in the spring.
Aeratingis the second step needed to keep your lawn as healthy and water efficient as possible. If you have an older lawn, or have highly compacted soil, you should aerate twice a year -- once in the spring and again in the fall. If you are aerating, or hiring someone else to do it, run the irrigation first and flag all your spray heads or rotors. This prevents inadvertently creating the need for sprinkler repairs! Aerate the whole lawn one direction and then again perpendicular to the first pass.
Also, regularly sharpen the blades on your mower and set it up as a mulching mower. Your mowing height should be as high as possible to help maintain a healthy lawn and conserve water.
Watering correctly is most important, so maintain your irrigation system year-round, and follow the Water by the Seasons watering recommendations. Check all the filters on each of your spray heads or rotors, then run your system to ensure that all of your spray nozzles or rotors are aligned and aren’t clogged. Repair or replace anything that isn’t working properly. Also check the base of each spray head to make sure you don’t have a leak at the base. The ground will probably be soft and squishy if there is one. To improve efficiency of your system, choose high efficiency sprinkler nozzles (rebates of $2 are available).
One last thing. Kick those shoes off and go enjoy that lawn!
