Walk the Line: A mid-summer check of your irrigation system

by 505 Outside | Jul 31, 2026 | Do It Yourself (DIY), Home Page, Maintenance, Summer, Water Conservation, Watering and Irrigation, Xeriscape

Up to 50% of outdoor water use is wasted due to lack of service. In just 15 minutes, a broken sprinkler could waste about 225 gallons of water. To put that in perspective, that’s more than the daily water needs for 3 Albuquerque homes.

If that broken sprinkler is set to run in the middle of the night, it could easily go a full week unnoticed, which would end up wasting 1575 gallons of water. That’s as much water as most Albuquerque residents use over an entire month during the winter. What if your leak goes unnoticed until you receive your next water bill? There goes 6300 gallons. If you’re like many of our customers and don’t pay much attention to your water bill due to auto payments, that broken sprinkler could run for an entire irrigation season unnoticed, wasting over 50,000 gallons of water. This one broken sprinkler can waste more water than what it takes to supply a home for a year. Consider the amount of water wasted citywide by that broken sprinkler along with all the other broken sprinklers, leaky pipes, and poorly programmed systems, and you can understand why it’s important for all of us to promptly address water waste issues in our landscapes.

Make the time to “walk the line”. While your system is running, walk the perimeter of your property and check your system. Do this a minimum of once a month for sprinkler systems. If you have a drip system, check it more often as they’re more susceptible to damage. If your system is over 20 years keep an eye on it as components are going to fail more frequently on older systems.

When you walk the line, it’s important to use all your senses, not just your eyes. Pay attention to the feel of the surface you’re walking on. If you feel a squishy spot below your feet, you probably have a subsurface leak. Also, listen, your brain is remarkably good at picking out sounds that are out of place, and can lead you to a leak.

Monthly Walk the Line Checks:

Leaks:

Sprinkler System Leaks: Quickly catching leaks will save plants and money. A broken sprinkler head is easy to identify. Less easy to see and often overlooked is a cracked pop-up spray nozzle (see photo). It’s important to know how your sprinklers look when they’re distributing water as intended, so if one starts spraying water differently from the rest, notice it and inspect it more.

Leaks from sprinkler head and cracked nozzle.

The good news is that replacing sprinkler heads and nozzles is easy. All you have to do is unscrew the old one to remove it and then screw in the new one. Just remember to replace them with the exact same brand part and model. Putting in the wrong part can result in distributing the wrong amount of water on your turf. This will cause brown spots either from your grass dying because it’s not getting enough water or from fungus because it’s getting too much. Unfortunately, most homeowners’ responses to brown spots is to apply more water. But remember, symptoms of over and under watering can look similar.

Make your life easy and keep the correct spare parts for your system on hand. If you’re uncertain, consider taking what you have to your local irrigation supply store for help with finding the right match.

When you purchase your new sprinkler parts, ask about high efficiency nozzles and pressure regulating spray bodies to upgrade your system. We offer Irrigation Efficiency Rebates for this equipment. However, do not mix and match traditional spray sprinklers with newer high efficiency options, they do not deliver water at the same rate. So, if you replace one sprinkler with an upgrade, you need to also upgrade at least the rest of the sprinklers in that zone and then make sure you adjust your sprinkler run time for the new rate at which water is applied with efficient nozzles.

Drip System Leaks:

If you have a drip system we recommend that you walk the line more often. Drip systems are easy to install and maintain, but they’re also easily damaged. One of the more common problems we see is cracked or punctured polyline tubing.

This is an inexpensive and easy fix. A small hole can be patched by inserting a “goof plug”. And a larger hole or crack can be repaired with a repair coupling, just make a clean cut and connect the two pieces with the correct size coupling. It’s a good idea to always keep goof plugs and the right sized couplings on hand if you have a drip system. A tackle box can be useful for all the parts. After the repair, run the system and observe the zone running to make sure the repair was successful and that you don't have other leaks.

Another common issue with drip systems is missing emitters. This is also an easy and inexpensive fix. You just need to pop on a new emitter with a replacement that delivers water at the same rate as the old one.

If you are frequently loosing emitters it's highly likely that the pressure in your drip zone needs to be reduced. Each drip valve should have a pressure reducer installed to match the pressure the parts were designed for (15-30psi). If yours doesn’t, consider installing one ASAP. Hold on to your receipt so you can apply for our irrigation efficiency rebate for pressure reduction within 90 days of the purchase or service.

Valve Assembly Leaks:

The picture of the left shows a valve box filled with water due to valve assembly leaks and the picture on the right shows a backflow preventer leaking due to an old or broken washer.

When you’re walking the line turn on the system then start at the valve assembly. This is where the whole irrigation system begins. It includes a valve (which is usually inside a valve box under a green or brown plastic cover) and a backflow preventer. The valve opens to turn on the water supply to the irrigation system and you should not see water in the valve box. Leaks often start gradually and they may not be immediately obvious so it’s a good idea to open the lid and look for water in the valve box when you’re doing your monthly system inspection. The valve assembly needs to include a backflow preventor. The backflow preventer is what prevents contaminated water from your landscape from siphoning back into your home’s water supply.

Valve box and backflow preventers.

If you are uncertain of whether or not you have a backflow preventer or you can’t locate your valves, you can always reach out to us through our “Ask an Expert” email us at AskAnExpert@abcwua.org

Other Water Leak Clues:

Even when your system isn’t running, there are clues you can look out for that can alert you to leaks and broken sprinklers. If you see ponds in your turf or in the street in front of your house, you might have leak. Other clues to look out for are things like algae growing on the sidewalk, or popped off sprinkler heads lying in the grass.

Another great visible leak clue is sediment flow. When water flows, it moves soil with it. So, if you see sediment around a sprinkler head like in the picture at right, or flowing across the sidewalk like in the top center, it’s a good sign that there is a leak below the surface.

Finally, one of the best clues you have is your water bill. If you notice an unusual jump in your bill, it’s a good idea to check your irrigation system for leaks. There is also a free online water use tracking tool we offer called HomeConnect, which allows users to view nearly real time data on their water use. With HomeConnect, you can view your water use down to the hour which allows you to familiarize yourself with your daily water use patterns so you can catch abnormal usage before it drives up your water bill. Set your water use thresholds so you can get alerts via email or text if your use goes above a set limit, this can also help avoid property damage at a rental or if you’re out of town.

Sprinkler Aim: Check for Efficient Alignment, Proper Throw, Consistency

When you’re walking the line on your sprinkler system, check that your heads are spraying water onto the grass not pavement or other areas that don't need water. If you see overspray, you can usually fix it pretty easily by adjusting the throw radius. How you do this will depend on the type and brand of sprinkler you have. Some sprinkler nozzles require a special adjustment tool, so if you need one, make sure you have it handy when you walk the line.

Now with some grass it’s impossible to avoid overspray, like narrow strips next to pavement like you see here. These are fantastic opportunities for a Desert Friendly Xeriscape Conversion. This rebate gives customers $3 per square foot for transforming their unwanted or inefficient grass to a healthier xeriscape that contains plants, trees, mulch and drip irrigation.

Another important aspect of checking your aim is looking for overflow. If you see water seeping off the grass, that tells you that the water isn’t soaking into the soil anymore, and no more water should be applied. This can usually be fixed by cutting back the time on your irrigation controller. Now if your grass needs more water than what can be applied before it starts running off, you can program your controller to a “cycle and soak” pattern. To determine the run times run your sprinklers until you see water is about to overflow. Then turn the sprinklers off, let it soak in for about half an hour, and run it again to meet your turf irrigation requirements. This is an excellent practice to help your grass develop a healthy and more drought tolerant root system, and it ensures that all of the water you’re paying for is benefiting your grass instead of being wasted in the street (which can result in a fine). Report Water Waste

Another solution for overflow is to replace all your spray nozzles with high efficiency rotating sprinkler nozzles, which we offer a rebate for. These nozzles apply water at a slower rate than traditional nozzles, giving water time to infiltrate to the root zone.

You should also make sure your sprinklers haven’t sunk or tilted. Take a close look and make sure that the outer radius of your sprinkler is throwing to the head of its neighbor what we call head to head coverage. And make sure that all the sprinkler throw patterns look consistent. The even distribution of water on your turf will help you avoid brown spots and uneven growth.

It’s very difficult to grow turf on a hill, the top can receive 2x as much water as the bottom. High efficiency nozzles and cycle and soak can help but, you’ve got another excellent candidate for a Desert Friendly Xeriscape Conversion rebate.

Clogs:

Automatic valves, drip emitter, end cap, basket filter.

Clogs in the system can be another cause of water waste. When sediment and debris collect in your system, water doesn’t get to the plants. And what do we tend to do when we see the plants struggle? Turn up the run times. That’s not going to help your plants.

If you have a drip system, before you turn it on for your monthly check, take one minute and open the valve box cover, unscrew the filter, which you can see in the picture up top, and clear out any debris you find. If you don’t see a filter, it's a good idea to get one installed. Once you turn the system on, inspect your emitters to make sure water is flowing as it should and clear any clogs that you identify. On the green-topped emitter pictured on the bottom left, this is easily done by rotating the flag and removing it from the main body of the emitter, place your finger over the hole to flush it (if the system is running) and replace the flag. Other types of emitters need to be replaced if clogged. It’s also a good idea to flush your line during your monthly check, which is done by removing the end cap while the system is running. If you don’t have an end cap, they are super easy to install and we recommend installing one to make maintenance easier.

To identify clogs in a sprinkler system, look for sputtering sprinklers. If you look closer and don’t see a cracked nozzle, you probably have a clogged filter basket. To fix this, simply turn off the system, unscrew the nozzle, pull out the basket filter and wash out the debris.

Controller:

Controller

Our monthly service tip is to click through your controller settings on your timer. With this you’re looking out for a couple of things.

First, make sure that your settings haven’t unexpectedly changed as power surges and weather events can disrupt your controller's programming. If you’ve installed a fresh backup battery at the start of the season, which we recommend, you shouldn’t have to worry about a power failure wiping out your programming.

Another issue we come across is mystery programming. Controller programming is often not intuitive and sometimes well-intentioned people accidentally program a system to run the same zone multiple times, which ends up wasting water. If you have questions about programming your controller, email AskAnExpert@abcwua.org.

Most importantly, check that your controller is set appropriately for the season. You should not be watering the same in October as you were in June. If you need guidance on watering schedules, check out our Water by the Season charts.

Now if making regular adjustments isn’t something you’d realistically do, you can purchase a Smart Controller which will figure it all out for you. These are wifi enabled devices that will calculate how much water your landscape needs based on local weather conditions and make the necessary adjustments for you. We've calculated that if everybody in our service area adjusted their sprinklers for the seasons we would easily meet our water conservation goals. We’ll give you 25% off up to $100 rebate back on your water bill for installing one.

Check out our Irrigation Efficiency Guide.

Best Practices and Common Mistakes:

A quick note about your mid-summer check. Make sure you’re adjusting for plant growth. If you have a drip system, move your emitters to the edge of the plant’s root ball, or drip line. You want to avoid the situation where the emitter is placing water directly onto the trunk of established trees and plants.

With sprinkler systems, maintain the vegetation so it doesn’t interfere with the streams of water. Trim back plants for sprinkler clearance. And when it comes to grass height if the grass is too tall it will block the sprinkler. If it’s too low, your grass doesn't shade its roots and can dry out quickly making it susceptible to drought stress. Aim for grass height between 3-4” Check vegetation around irrigation.

If you suspect you’ve got a problem with your irrigation system and you’d like help troubleshooting it, you can always contact us through “AskanExpert” and we can walk you through it or even come out to your property for an irrigation consultation.

Keeping Cool This Summer While Saving Water

by 505 Outside | Jul 2, 2026 | Do It Yourself (DIY), Maintenance, Outdoor Living, Summer, Water Conservation

Over 40% of Albuquerque homeowners use evaporative coolers, while the rest use some type of refrigerated air system. Today’s evaporative coolers (also known as swamp coolers) provide a practical, energy-efficient way to cool air in the low humidity climates found throughout New Mexico. Evaporative cooling isn’t a new concept. In fact, it’s the oldest known method of cooling hot, summer air to make living spaces more comfortable. Ancient Egyptians hung wet material so the wind could blow through it to create a cooling effect. In an evaporative cooler, warm air is cooled as it passes through porous pads that are kept moist by water dripping on their upper edges. A blower wheel pulls outside air through the wet pad, and the cool, humidified air is then circulated through the house. In the process of cooling the air, evaporative coolers provide an additional benefit of removing dust and pollen that can cause allergies and asthma attacks.

Evaporative coolers are very effective, particularly when the relative humidity (the moisture content of the air) is low. An evaporative cooler works best during the hottest time of the day, because relative humidity drops quickly as temperature increases. Studies show that a typical evaporative cooler uses only about one-third the energy of a refrigerated air conditioner,

The big question is how much water do swamp coolers use? Water requirements for an evaporative cooler will vary with the size of the house, its orientation toward the sun, window area, type of landscaping, proximity to hard surfaces and other structures, temperature preferences of the occupants, local climate, how many hours the cooler runs, and water quality.

In an average weather year, a 1,500-square-foot home in Albuquerque might use 7,250 gallons (based on the evaporative cooler running 1,130 hours). In an unusually warm year, these water requirements would be significantly higher. Virtually all models of evaporative coolers now available recirculate the water that drips from the pads, resulting in an efficient use of water. (Older, less water-efficient evaporative coolers might not have a pan to catch and recirculate water. If so, excess water shall be directed to plant material. Or replace the old cooler with a recirculating one.)

Some coolers have a “bleed-off valve” to drain a portion of the recirculating water to prevent excessive mineral buildup on the porous pads. Bleed-off water can increase overall evaporative cooler water use by 50% or more, which could increase total evaporative cooler water use to 11,000 gallons in Albuquerque. A more water efficient alternative to continual bleed-off is a “dump pump,” which empties the cooler pan at regular intervals to reduce mineral buildup.

Waterwise Tips for Evaporative Coolers

Instead of turning on your cooler when it’s 79 degrees outside, wait until it is 85 degrees. Your cooler will use 50% less water.
Turn on the water pump a few minutes before turning on the fan to give the cooler pads a chance to become saturated.
Open a window 1-2 inches in the rooms you want to cool. This will draw cool air into the rooms and give warm air a chance to escape.
In the evenings or when it’s not quite so hot outside, run your cooler fan without running the water pump. You’ll get nice, cooling airflow without using any water at all!
Also run just the fan on rainy and high humidity days when your evaporative cooler is significantly less efficient.
To keep your cooler from wasting water, check it for leaks monthly during the summer season. Take a look at its filters, pads, pump and reservoir. Replace your cooler pads at least once every summer, preferably twice — or aim to clean them with soap and water.
Install a digital thermostat. Digital thermostats allow you to use much less water than you would otherwise because once your home gets to your desired temperature, it will automatically shut off.

Additional tips to keep your home cool, harvest water and reduce energy use

Direct any water from a refrigerated air conditioner or mini split condenser toward plants.
Servicing your refrigerated air conditioner by performing general maintenance such as replacing or cleaning air filters can lower energy consumption by up to 15%. Add a calendar reminder for the first day of spring to check your air conditioner’s evaporator coil. This should be cleaned annually to ensure the system is performing optimally.
Cooling your home with ceiling fans will allow you to comfortably raise your thermostat about 4 degrees. In the summer, fans should turn counterclockwise so air pushes downward, circulating the cooler air in the room and making the home feel cooler. Make sure to turn off ceiling fans when house is empty.
Window treatments or coverings such as blinds, shades and films can help reduce the heat when temperatures rise. Close blinds and curtains on the East, West and South sides when nobody is home to keep the sun from heating up the house.
Air loss through ducts can lead to high energy costs, accounting for nearly 30% of a cooling system’s energy consumption. By sealing and insulating your ducts, you can lower your energy bills.
Avoid using heat-producing appliances like clothes dryers, dishwashers, stoves and ovens during the hottest part of the day. Use your grill for cooking and hang dry your clothes.

How to Get Gravel Out of Your Yard

by 505 Outside | Sep 2, 2025 | Blog, Do It Yourself (DIY), Maintenance

Maybe you recently moved into a house that has never been updated — think avocado tile in the bathroom and shag carpet in the sunken living room. You look outside and the theme continues — a sea of gravel and railroad ties. As with interiors, home exterior fashions and landscaping styles change over time. We once thought of gravel as low maintenance and tidy, but now are finding out isn’t the best choice as far as sustainability and community health. Thankfully, through the efforts of local designers, tree experts and Water Authority resources, there is a sea change in understanding the problems that gravel, weed fabric and plastic sheeting can cause in our neighborhoods.

Gravel soaks up heat and radiates it back into the neighborhood, warming up the city. We’ve also found out that gravel and weed fabric don’t discourage weeds, instead their seeds and dust settle on top, sprouting in no time. This leaves few options other than using herbicides, because pulling them can be difficult once they’re rooted in the weed fabric, and using a hoe is difficult in gravel larger than crusher fines. Additionally, tree and plant roots need two things: water and oxygen, neither of which permeate through old weed fabric clogged with silt. Wanting to install some flowering xeric plants near your new front door? That’s going to be a challenge — moving the rock out of the way, cutting the weed fabric and finding a way to install drip irrigation under the existing weed fabric and rock. Perhaps you’d like to invite pollinators to your new yard? Well, our native (and solitary) ground nesting bees won’t find a home in your yard because they can’t burrow through the weed fabric or rock to nest in the soil.

But all hope is not lost. Whether you’re aiming to remove all the gravel, just take out some around existing trees to improve their health or make your outdoor living space cooler and be sure water is soaking though the old weed fabric (or worse, plastic), there is help.

If you have a limited budget and time but want to do some good, use a piece of rebar to poke holes in the weed fabric around your existing plants. This will ensure they can use some of our precious rainfall and allow for oxygen exchange.

Have an existing tree that’s suffocating in heat absorbing rock? Time to grab the wheelbarrow and a shovel. If you’re removing small sections at a time, start with areas with the dripline of the tree. Here is where weed fabric is actually useful: In good condition it can make the gravel removal easier. Lift up the fabric carefully, using it to form the rock into piles that can be scooped up more easily. A square end shovel can be useful here because it’s less likely to rip the fabric underneath as you work. If you need to remove large rock like cobble, I recommend sitting on a protective pad and doing it by hand. Have a 5-gallon bucket or wheelbarrow right next to you to put it in. Some homeowners construct a basic wooden frame out of two-by-fours and wire mesh to make a screen to separate the gravel from dirt. Size it to fit over your wheelbarrow so you can transport the dirt more easily.

Albuquerque’s three convenience centers accept about two wheelbarrows full of rock (or dirt and concrete). Be sure not to take too much because you may be turned away. For larger amounts, you can try the Sandoval County Landfill in Rio Rancho or Southwest Landfill on Albuquerque’s southwest mesa; be sure to call first to confirm they will accept it. Alternatively, many homeowners are looking for gravel for erosion control under downspouts so try placing a FREE add on Craigslist, Facebook Marketplace or Nextdoor. It will most likely get picked up in no time.

Now if your whole yard is full of gravel, you’ll probably need to call in someone who is better equipped, someone with a skid steer (Bobcat). Front yards are easier, but backyards can usually be done with a smaller machine if access is limited.

The obvious question to follow is, what’s next? We recommend wood chips spread to a depth of 4 inches. This mulch (without weed fabric) helps improve the soil over time and allows the tree and plant roots to breath. It also cools the environment a few degrees compared to rock. Several suppliers in the Albuquerque area sell mulch, and they all deliver. They’ll be happy to tell you how much you need if you know the dimensions. Additionally, several places offer free or discounted mulch. Call up large tree removal companies and see if they have any or head to the East Mountain Transfer Station in Tijeras and pick up a cubic yard for $5. There is also a great website called ChipDrop that connects tree service companies with homeowners who want mulch — you may have to wait a while for the stars to align but it’s totally free.

As in most fields, change is slow. Older ways of thinking permeate the landscape industry, but some steps in the right direction (like wood chips instead of gravel) can make a difference over time.

Why We Hate to Love the Bermuda Lawn

by 505 Outside | Jul 30, 2025 | Blog, Lawn Care, Maintenance, Planting, Watering and Irrigation

If you have heard of Bermuda grass or live in one of the older areas of Albuquerque, just the name might make you flinch or grimace. The reason it gets a bad rap is because it is dormant in winter, it spreads like crazy into garden beds and can magically appear out of a dirt mess after monsoon season.

You may be surprised to hear that some of us actually like Bermuda grass lawns. In fact, I’ve even planted the grass in my backyard. I’ll take you through the pros and cons and why I’ve come to love the Bermuda grass lawn. It can be the right plant for the right space to fill the right need.

Many homeowners would like turfgrass but feel irresponsible watering a lawn in the arid Southwest. The key to choosing a turfgrass is to determine the one most suited to the specific needs of your landscape The Water Authority is not anti-lawn that is efficiently irrigated and physically used and enjoyed. Bermuda grass cultivars are one means of having a traffic/play/dog tolerant surface that uses half the amount of water of a traditional cool season lawn

According to the “turf research lab” at New Mexico State University (NMSU), “Certain turf characteristics, such as climate adaptation, water use, traffic tolerance, color, quality, maintenance requirements, and available resources, are all factors that need to be considered when selecting a turf species. Climatic adaptation and traffic tolerance, which largely determine the future use of the turf area, are the two most important factors. Many problems encountered in maintaining turfs can be attributed directly to selecting the wrong turfgrasses for Albuquerque’s difficult growing conditions and to the lack of resources, especially water, that homeowners and professional turf growers face in the state.” This means that understanding how much traffic (kids and dogs playing) and our very dry local climate are how we should be selecting turf grass species not what the big box store happens to have in stock.

There are two different categories of turfgrasses: cool season and warm season. Common Cool season grasses are Kentucky Bluegrass, Perennial Ryegrass and Tall Fescue. These are cold tolerant, green most of the year and hold up to extensive foot traffic. But they use a lot of water, up to 50” a year If efficiently irrigated. The water authority frequently has many customers (especially commercial customers) that water grass 80-100” per year! in a town that only gets an average 8” of precipitation. Common warm season grasses are Bermuda grass, Blue Grama and Buffalo Grass. Warm season grasses have a shorter growing season. This means they green up in mid spring, are low maintenance and require less water than cool season grasses. But blue grama and buffalo grass can’t take extensive foot and paw traffic plus they go dormant in the winter.

In my case, I had an existing native buffalo and blue grama grass lawn. It had always been perfect for our home. It’s native, low water use, easy to maintain and beautiful to look at. Fast forward to three kids and two dogs later. I was noticing wear and tear in certain areas of my lawn from two large dogs leaving run paths and kids playing soccer. I’m a professional landscape architect and knew Bermuda grass is a prolific spreader but in this case, I was actually looking for a grass to take over and fill in around the heavily accessed places in my yard. I found a species that could meet both my needs called Cynodon hybrida Dog Tuff ™ Grass Plugs, originally from High Country Gardens. There are many cultivars available check out the many options researched by NMSU. It is a Bermuda grass hybrid perfect for high traffic and play areas. It has excellent durability in yards with dogs. Once established, it is highly weed resistant, deep rooted and provides a soft, cushioned feel for bare feet.

The grass itself “produces an extensive system of creeping rhizomes and stolons commonly called runner roots that often have a scaly appearance. It also produces fibrous roots at the stem nodes. Bermuda grass reproduces through seed and vegetatively through rhizomes and stolons,” according to NMSU, allowing it to spread with just a little bit of water, around 20” a year. I find that it rarely needs mowing because of the traffic we give it. I mow it about twice a summer to the highest setting my mower goes around 4”.

The data on this grass comes from NMSU, which has turf study sites in Las Cruces and Farmington. A few key points from their study sites mentions that “Bermudagrass (Cynodon dactylon) is similar to Kentucky bluegrass in its tolerance to traffic and turfgrass recuperative capabilities after stress or damage, but it appeared to be more aggressive than Kentucky bluegrass during hot weather in mid-summer.” NMSU evaluated five different varieties of bermudagrass, Guymon, Riviera, Wrangler, and Yukon, at both their northern NM and southern NM sites. “Riviera was given higher quality ratings than the other varieties due to finer leaf blades. Being a warm-season grass, the bermudagrasses required less irrigation to exhibit a quality comparable to the cool-season grasses.”

The shocking reason homeowners don’t like Bermuda grass is that it can become a troublesome weed, especially in southern NM, so it is wise to separate this grass from garden areas with a dry, unirrigated buffer strip, concrete mow strip at least 8”x 8” or other barrier. I like to design a concrete walk, patio or edger around these grass areas.

When placed strategically in a landscape this water friendly, high traffic, low mow grass is a winner in my book.

I’ve Xeriscaped My Yard, Now What?

by 505 Outside | Jun 30, 2025 | Blog, Design, Maintenance, Water Conservation, Watering and Irrigation, Xeriscape

Your new xeric plants are in, and everything is looking good. What do you need to do to keep it that way? Start by looking at your irrigation controller. It may be programmed to apply water too frequently and/or for too long in order to get the plants started. If you hired a contractor, they may have set the controller to water every day because it’s easier than getting a call about a plant that doesn’t look great.

Many desert-friendly plants and trees evolved to survive on very little precipitation but also to make the most of abundant rainfall when it does happen. They’ll store the water in their roots or grow larger (and produce more seed for dry years) than they would with only adequate water. A xeriscaped yard doesn’t automatically “save” water — it is up to the homeowner to do the actual water saving by adjusting their irrigation controller. My dog would be “happier” if I fed her as much as she wanted, but it’s wasteful (among other things) to do so. Watering your desert-friendly plants too much may cause them to outgrow the space they were designed for, which might mean pruning them more than they need so they don’t grow against the house or over a path or outcompete other plants. Overwatering also creates lush, tender growth that is more attractive to pests and susceptible to frost damage.

A recent study in Arizona found that xeriscaped yards didn’t have reduced water usage because the homeowners applied the same amount of water as they would for a traditional yard with a lawn and non-natives.

Here are steps you can take to make sure you’re watering correctly for your new landscape and keeping your plants healthy:

Reduce the number of emitters if needed: The best way to do this is by cutting off the drip emitter and installing a “goof” plug in the end of the ¼ inch tubing. This is preferable to trying to pull the ¼” coupler out from the larger line, which creates a larger hole that can’t be easily plugged.

Check your irrigation controller: You’ll want to keep the soil moist around the newly installed perennials, shrubs and trees for the first week, and that might mean watering every day if it’s above 90 degrees. After the first week, switch to watering every other day. Then on week three, switch to twice a week. Exceptions would be for cacti, which I would soak once when planting and then water once a week for the first month before tapering off to once or twice a month until established. (Perennials / grasses - 8-10 weeks, Shrubs - 1 year, Trees - 1-3 years.)
Check that drip emitters are working properly, especially if a plant looks wilted: Drip emitters often get clogged after a repair is made in the larger ½” or ¾” poly tubing. If you’re using “flag”-shaped emitters and one is not flowing, you’ll want to grasp the body of the emitter while you turn the top “flag” shape counterclockwise 90 degrees to allow the top to separate from the rest. You should do this while the zone is running so that you can see if any emitters aren’t working and so that the water pressure can clear the clog. Once you’ve twisted off the top, you should have a strong flowing stream of water coming out. Hold your finger over the water stream, forcing it into the drip outlet, which clears the clog.

If you’re using “button”-shaped emitters and one is clogged, you’ll need to cut it off and replace it. Don’t try to pull it off the ¼” tubing, just cut it off and plug in a new one so that the barbed insert has fresh (not stretched out) tubing to fit into.

Keep up with plant growth: As your desert-friendly plants grow larger, you can move the emitters farther away from the base of the plant and add new ones if needed; larger plants require more water. There are several ways to do this. You can poke a new hole in the nearby larger poly tubing, insert a ¼” coupler, run an additional ¼” line to the plant and add an emitter. However, if the main poly line is more than a couple of feet away, install a ¼” “T” in the spaghetti tubing and go from there. It saves time and means fewer holes in the main poly line. Remember, when installing ¼” couplers into the main poly, always poke the hole in the side, not the top; that way if you step on them by accident, they won’t break off. Also, if your plants are on a slope, the emitter should be on the uphill side, so water flowing downhill will cover more of the root zone. Check that water wells are still in place and holding water around the plant.

Inspect your trees: Check the leaves for any insect damage and the underside of leaves for insect infestations. Also make sure the mulch or gravel isn’t covering up any of the tree trunk above the root flare, which traps moisture that can cause decay or rot. Particularly in fruit trees, this can also allow detrimental insects access to the trunk where they could bore into it.
Check the soil around the base of your plants: Often during initial watering, the soil will settle into the planting hole and can expose the root ball, which causes it to dry out quickly. If you observe or suspect this, kneel in front of the plants, move the mulch out of the way and scrape the surrounding soil back around the plant to cover up the root ball. Then replace the mulch and reposition the drip emitter as necessary.
Learn the common or scientific names of your plants: If you don’t have a list, plant tags or a detailed landscape plan, some newer smart phones have a plant identifier built into the camera app (no need to remember the app store password and download another app). The closer you can get to the plant — showing leaves, branch shapes and flowers (if any) — the better the app will work. The phone (as we all know) can be wrong, but it will give you a place to start. Alternatively, send an email with photos to askanexpert@abcwua.org and we can help you identify

Once you know the plant names you can look them up in our xeriscape guide to reacquaint yourself with their water needs and mature sizes. Need help remembering the plant names? Often the plants themselves can tell you. Is it a catmint? Rub the leaves and smell the minty aroma. Turpentine bush? Lemony pine smell, for sure. Maybe it’s the shape of the leaves. Fernbush? Examine the leaves closely and see how they resemble an actual fern from a rainier climate.

Recognizing Water Stress in Trees

by 505 Outside | Jun 30, 2025 | Blog, Maintenance, Tree Care, Watering and Irrigation

As a landscape professional, one question I’ve always dreaded is, “How much should I water this tree?” Honestly, there are so many variables that giving a blanket answer is fanciful. More than likely, a part of the answer is, “More than you are now!” Trees are big plants with lots of leaves, and they can transpire a lot of water. That water is “lost” while the leaves are making sugars via photosynthesis, so trees have a high water demand.

If supply doesn’t keep up with demand, the tree gets stressed. How do you know if your tree needs more water? Learning to recognize signs of water stress can help you stay on top of your trees’ needs. There are some common symptoms and situations that may indicate that they are thirsty.

Water stress can be long-term (chronic) or sudden (acute). Chronic drought stress occurs commonly, as many irrigation systems are set up to be adequate for a newly planted tree. As that tree grows, though, it has more leaves and needs more water. Adding emitters and covering more ground is key to keeping up with the growth. Acute drought stress is less common; it happens when a tree suddenly loses most or all of its water supply, which up to that point was adequate. Finally, most rare of all, water stress can happen from too much water in the soil.

Chronic drought stress occurs when trees haven’t had enough water for some months or years. These trees will have smaller than normal leaves, and those leaves will be sparser in the canopy than normal for that species. They may be off-color, not as vibrantly green as normal. Often, there is dieback in the small, outer branches and twigs.

Annual growth will slow down. Evidence of this can be seen in small diameter branches if you can identify the ring scars that mark the annual growth segments. Ring scars are lines that circle all the way around the twig; they are not bud scars that form at each dormant bud and do not circle the twig. If annual growth segments are shorter last year than the year before, something bad is going on.

*The short distance between these ring scars indicates a year of poor growth. This may have been the year it was planted, as that is stressful to trees.*

In conifers, we see similar evidence — smaller and fewer needles and shorter growth segments. Often, pine needles will brown out from their tips, maybe just a little or maybe halfway. Conifers keep their leaves for several years, so partially browned needles can really slow down growth potential as the brown part isn’t making sugars. Chronically drought stressed conifers abound in New Mexico forests. They are more susceptible to bark beetle attacks than unstressed trees. Combine beetle-killed trees with very dry trees and wildfire becomes a huge concern.

Acute drought stress might happen when a trench cuts through the root system, such as with a new sewer line is installed. Acutely stressed trees tend to have sudden yellowing and then drying of leaves, maybe just on one side of the tree (the trench side, for example). Acute stress is hard for the tree to recover from.

In either chronic or acute stress situations, leaves may develop brown and dead edges. Termed “marginal browning,” this happens when excess salt in soil water gets deposited at the furthest edge of the leaf, building up to toxic levels. Leaves will often turn pale and then yellow during mid-season, well before fall temperatures normally trigger that.

*Yellowing of leaves can be a sign of stress.*

How about those few trees getting too much water? In some ways, symptoms can mimic too little water. When the soil is very wet, roots stop functioning due to lack of oxygen. This is of most concern for dryland conifers like juniper and pine. Usually, it is linked to an irrigation system that only has emitters at the base of the tree that run often. The tree doesn’t have the fine root mass near the trunk to take up the water, so the soil remains wet. Fungal diseases are likely to pop up, leading to root death and then tree death. Another symptom of overly wet soils shows up in leaves on deciduous trees like cottonwood — oedema. These are corky scars on the surface of the leaf.

You can reduce tree stress with proper irrigation. Trees seem to do well when irrigation is deep, broad and not too frequent. Watering every day is actually not helpful, especially when right at the base of the tree. Cover the soil with an organic mulch to keep the soil cool and the moisture available to your trees.
