Common Mistakes for Drip Irrigation Installations

by 505 Outside | Oct 7, 2026 | Do It Yourself (DIY), Home Page, Watering and Irrigation, Watering Recommendations

In our hot, arid climate, drip irrigation efficiently waters trees, shrubs and other landscape plants by delivering the right amount directly to roots, promoting healthier plants and reducing waste. The drip systems greatest advantage is flexibility. It’s easy to install and modify a drip system as a landscape grows and changes. However, they can be incredibly wasteful if not installed and maintained correctly. Like many things, it’s easiest to learn from mistakes. We compiled the most common drip irrigation mistakes we see in our Albuquerque landscapes.

Mistake 1: Not installing a drip filter/pressure regulator combination.

Average water pressure in Albuquerque ranges from 45-80 PSI, but drip irrigation systems have been designed to operate best at 25 PSI. All drip systems should have a pressure regulator to reduce the pressure and a filter to screen dirt and debris from water. If you notice drip emitters are popping off or leaking, then the water pressure is too high. Install a drip filter/pressure regulator combination downstream of the valve, immediately after the backflow preventer or vacuum breaker. If your system has a pressure reducer but emitters keep popping out of the ¼-inch distribution tubing then the end of the tubing may have become stretched. If so, cut off a small section of the tubing and reinstall the emitter into the fresh tubing to create a more secure fit.

Mistake 2: Relying on the existing sprinkler heads and sprinkler lines for drip irrigation.

Don’t rely on the old piping when converting sprinklers to drip. Abandon all old PVC and galvanized lateral lines and install sprinkler irrigation directly downstream of the valve assembly and backflow preventer. 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 xeriscape comes from abandoning leaky underground piping and fittings.

Mistake 3: Not burying or covering drip irrigation tubing.

One of the best ways to extend the life of your drip system is to keep it out of direct sunlight and hidden from rodents. Although drip tubing is UV-resistant, prolonged exposure to the sun gradually breaks down the plastic, making it brittle causing it to weaken and leak over time. To protect from the elements, ½” and ¾” distribution tubing should be installed with landscape staples and buried in a 4-6” depth trench and cover with 3-4″ of mulch.

Mistake 4: Going over instead of under retaining wall.

Avoid running drip tubing over the top of retaining walls (or landscape edging) whenever possible. A better option is to install a PVC sleeve beneath the wall before construction. Be sure to cover both ends of the sleeve with tape to prevent soil and debris from entering during construction. When you’re ready to install the irrigation system, simply feed the drip tubing through the sleeve. The sleeve protects the tubing from damage while also providing a convenient pathway for future repairs, replacements or system modifications.

Mistake 5: Runs of ¼-inch distribution line (often called spaghetti tubing) that are too long.

In a perfect world, these smaller tubing lengths wouldn’t exceed 2 or 3 feet between the larger lateral tubing (½-inch or ¾-inch size) and the base of the plant. Keeping ¼-inch distribution tubing short, pinned down with landscape staples, and covered effectively with mulch helps prevent pressure loss from long runs plus reduces the opportunity for physical damage from UV sunlight, rodents or dogs.

Mistake 6: Having unnecessary fittings.

Every fitting creates an opportunity for leaks, compared to a continuous run of tubing. Whenever possible, use a single uninterrupted length of tubing. For example, if the tubing can be gently bent around a corner without kinking, there is no need to install a 90-degree elbow fitting,

Lots of dripline connectors and long runs of ¼” distribution tubing – likely leading to damage and leaks.

Mistake 7: Not using enough landscape pins or staples.

Properly securing irrigation tubing with staples keeps it in place. Temperature fluctuations can cause the lines to expand and contract, which, over time, can allow the tubing to migrate to the surface, exposing it to sunlight and physical damage. Pin down the larger lateral supply line tubing and use at least one landscape pin on each ¼-inch tubing line to prevent the emitter from moving away from the plant’s root zone.

Mistake 8: Insufficient emitters for existing trees and plants.

This problem is most common when a lawn is converted to a xeriscape landscape with drip irrigation. Existing trees may have relied on sprinkler irrigation for many years, allowing their roots to spread throughout the lawn and often well beyond the edge of the canopy. When sprinklers are removed, homeowners or contractors sometimes replace the irrigation with just two or three emitters near the base of a mature tree. This does not provide enough water, and the water is not being applied where the majority of the feeder roots are located. This issue also occurs in newly installed landscapes when plants receive too few emitters; if the emitters are not repositioned, the problem continues as the plants mature. For newly installed landscapes use our Irrigation Guide page 28 to learn how many emitters should be installed per plant.

Mistake 9: Not separating trees and perennials into different irrigation zones.

We often find that customers have their low water use plants and medium water use trees on a single drip irrigation zone. One of the best irrigation practices – called ‘hydrozoning’ is to place trees and desert-friendly plants on separate watering zones. This allows each plant grouped by water need type to receive water according to its specific needs. Established trees typically benefit from deep, infrequent watering once or twice per month, while smaller plants generally require more frequent watering, often two to three times per week during the growing season. Separating these plants into different zones improves water efficiency, promotes healthier root systems and helps prevent both overwatering and underwatering. Occasionally, we come across a single irrigation zone or valve that contains both sprinklers for grass and drip irrigation for plants — this should always be avoided because it results in overwatered plants or underwatered grass.

Mistake 10: Not keeping emitters visible.

When walking through your newly installed landscape, you should be able to see the drip emitters positioned 2 to 3 inches above the mulch or gravel. (Emitters should also be placed on the uphill side of the plant.) Keeping emitters visible during the establishment period makes it much easier to verify that they are working properly and delivering water where it is needed. While they may not be the most attractive feature at first, the emitters will become less noticeable as plants grow and fill in. In a mature landscape, however, they can become hidden by plant growth and groundcover. In this case, the overall appearance and health of the plants provides clues if an irrigation problem exists. When you do need to locate an emitter, try listening when the drip zone first turns on. The sound of water flowing through the emitter can often help you pinpoint its location.

Mistake 11: Using specialty parts that aren’t readily available at most irrigation or hardware stores.

When designing and installing your drip irrigation system, it’s best to use common, readily available parts. Choosing specialized components that are difficult to find or incompatible with standard fittings can lead to frustration, delays in repairs and resulting plant stress when repairs or replacements are needed in the future. We recommend purchasing supplies from irrigation specialty stores, as they offer higher-quality products, stock the same parts from the same manufacturers, and have experts available that can answer your questions. Be selective in the parts you purchase and keep a stash of extra parts in your toolbox so you can make a quick repair and avoid wasted water or stressed plants.

The Dos and Don’ts of Autumn Landscape Maintenance

by 505 Outside | Oct 5, 2026 | Do It Yourself (DIY), Home Page, Watering and Irrigation

Autumn brings many changes to our landscapes and gardens. Certainly, we are enjoying the cooler temperatures and changing light. It is more inviting to spend time outside, and we may find ourselves more inclined to do some of that yardwork that was unbearable in the heat of the summer.

But what is necessary work in the fall garden? Some of us have a tidy streak and find ourselves compelled to rake up the leaves as soon as they begin to fall or cut back the flowers and grasses that mere weeks ago swayed in the breeze and lured in the pollinators. Hold your horses. Your sense of neatness, or perhaps the need to control or tame the wildness going dormant before you, may not be what is best for the garden.

You may have heard the phrase “Leave the leaves.” Increasingly, we are understanding the benefits of letting the fallen autumn leaves lie and, along with that, holding back on some of the pruning, deadheading and raking that may have been your fall garden ritual. There are good reasons to let your landscape and garden remain a bit messy, and science can help you understand why.

Leaves store nutrients for the plant they are attached to throughout the growing season, releasing them into the vascular system as the plant requires. When autumn arrives and leaves fall to the ground, these stored nutrients are slowly released back into the soil, even as the decaying foliage enriches the ground beneath it, adding to the organic profile of the earth and creating systems for all the beneficial microorganisms to flourish. Healthy bacteria, fungi and mycorrhizae thrive in the soil beneath a mulch of decaying organic matter, and the blanketed soil also holds moisture, insulates the soil and reduces the need for supplemental irrigation.

There are also many wildlife benefits to leaving a bit of messiness in the garden over the winter, especially for creatures that may be searching for natural food or nice hiding places to overwinter in, protected from the elements. In addition, there are ornamental benefits. For example, a native grass meadow can take on subtle color shifts, from greys to golds to russet tones, especially if graced with winter precipitation.

If we are fortunate enough to have precipitation in any form, the organic material left in the garden can act as a sort of sponge, soaking up moisture and slowly releasing it into the soil.

For a maintained appearance, rake the leaves and pine needles from patios and walkways if you wish, but let them accumulate and remain as free mulch in your flower beds, under trees and shrubs, on top of organic mulch such as bark or shredded wood, and on the soil surface between grasses in your meadows. You can add any excess to your compost pile if you have it. The exception would be if you had an issue with a fungus, such as powdery mildew. You should dispose of those leaves. If you have gravel or crusher fine mulch, you may want to rake the debris from those surfaces and recycle in appropriate areas of the garden or landscape.

If you have native and ornamental grasses, wait until spring to cut them back. Aesthetically, our plants go through a fall transition fading from red into russet browns and greys. This change signals the changing of the seasons, helping us align with Mother Nature. Erect stems and plump leaves will fade and crumble, setting up a beautiful contrast to the bright green growth of early spring and the tidy appearance after your spring clean-up and cut-back. The faded growth adds visual winter interest to the landscape, seeds for birds and protection for overwintering insects (even butterflies) as well as helping to hold soil moisture. The same goes for perennial flowers, like coneflower, penstemon, gayfeather and bee balm. These plants provide natural winter sustenance for birds and other wildlife and protect the sensitive crown of the plant from potential damage from freezing winter temperatures.

As for fall pruning of shrubs, there are several reasons to hold off on using your hedge trimmers and hand pruners there, too. One reason is that the spent flowers and seed heads on some shrubs such as blue mist spirea or chamisa also provide visual winter interest and food for birds. Some common landscape plants — like autumn sage, Texas sage and lavender as well as herbs like garden sage, rosemary, thyme and oregano — benefit from being left alone in the fall. The older outside growth acts as insulation to the more tender interior of the plant, protecting it from freezing temperatures. If you cut these back in the fall, you may find that winter damage has killed back much of the plant come spring.

There is something peaceful and restorative when looking at a winter landscape. You feel the earth resting after a season of heat and growth, the stored energy in slumber and silence, waiting for the shift in seasons to spring forth in renewal.

Rest with your garden. Let the quiet, meditative nature of the dormant period reset your own seasonal clock. Enjoy the cooler autumn days and the changing of the color, texture and mood of the landscape. Feel the gentle ebb of the need to do something and allow yourself to just sit with the slow season. You deserve a rest, too.

Junegrass, Koeleria macrantha

by 505 Outside | Oct 5, 2026 | Grasses, Home Page, Ornamental Grasses

Type: Evergreen

Exposure: Sun/Shade

Water Use: Medium

Mature Size: 18’ x 18’

Junegrass (also known as prairie Junegrass) is a cool season native perennial bunchgrass that is drought tolerant and grows well in dry soils. It forms clumps of fine textured blue green leaves with spikes of feathery silver seed heads appearing in late spring to early summer and drying to a tan color as the seed matures. Junegrass can self-seed but not aggressively. The clumps are 10-24 inches tall and can grow to a foot across the spreading tops.

Junegrass is considered a low to moderate water use plant, adaptable to many soil types. It prefers well-drained sandy, rocky or dry soil, and does not do well with heavy clay or wet soil. It does not thrive in hot, humid conditions, and can go dormant in the heat of the summer. It is hardy in USDA zones 3-9.

A lovely specimen grass, Junegrass can be grown in containers. It also looks great in mass plantings or in meadows of mixed native grasses like blue grama, side oats grama and Indian rice grass, along with wildflowers such as asters, coneflowers and penstemons.

Like most grasses, maintenance consists of simply cutting the grass back to a few inches close to the base in early spring before new growth begins. Any seed left on the standing plant over the winter can provide food for birds.

This grass has a fine delicate appearance, and the fresh forming seed spikes are striking when the sun catches the small, feathery heads. You may come upon this grass while hiking on a mountain trail in sunny openings between the trees.
