As Albuquerque area homeowners convert their high-water-use turf grass to desert friendly xeriscapes, many are opting for wood chip mulch rather than gravel or other aggregate, which can be hot and allow weeds to pop up.
The Water Authority checked in on two recent xeriscape conversion projects. These homeowners chose the DIY option for their front yards to save money. With all the resources available online, it has become easier to find how-to information on installing landscapes. The design, on the other hand, can be more difficult, and one of the homeowners chose to hire a professional. The other homeowner checked in with her mom who is an avid gardener, looked over resources from the library, and used online videos to pull together the design they wanted.
“I like the yard so much more now than the lawn we had before. The lawn would be pleasant about one or two days a month, and otherwise just felt like a chore and a needless expense. We’re lucky to live very close to a park, with a much nicer lawn than ours ever was, so when we want to play Frisbee or do ‘lawny’ things, we just walk the half a block to the park,” one homeowner said.
“While it took some labor to kill the grass, dig holes for the plants, install irrigation and lay down mulch, now when I look at my yard I no longer think, ‘Ugh, we need to weed/mow/fertilize/whatever.’ Now, I feel more joyful seeing all the different plants growing, and I’m always out there checking on my little plant friends.”
The other homeowner was motivated to create a landscape that “made more sense with the desert environment, used less water, helped provide habitat for pollinators and had a more natural look.”
Both homeowners chose to use wood chip mulch because it is extremely affordable and easy to install. They knew the advantages of mulch from their research and from seeing yards in their neighborhoods that use mulch. One of the added benefits, according to both homeowners, is attracting pollinators and other wildlife. “I see a lot more insects; I especially notice the bees,” one said. “There’s a family of roadrunners in our neighborhood, and they’re spending more time in our yard than they used to.”
Wood chip mulch is made up of chipped trees. This is a long-lasting mulch that decomposes slowly over bare dirt, retains moisture and is superior to other mediums at suppressing weeds. Most wood mulches available on the market are chipped flat and are consistent in shape and size. These are great in areas that receive foot traffic as they compact down to a firm surface.
Both homes installed a 3- to 4-inch layer of organic mulch over bare dirt. That depth is effective at stopping sunlight from reaching annual weed seeds, thereby preventing weed germination. The homeowners noted that mulch was easy to install and much less expensive than gravel, and they found that the mulch also was much cooler than the hot gravel.
“The main things we have noticed with the mulch are weed control and how well it retains water,” one homeowner said. “There are very few weeds that seem be able to germinate and make it through the mulch barrier. The weeds that do come up are actually very easy to remove by hand (my preferred method for weeding) because there is no artificial weed barrier or rocks to dig out.”
The advice both homeowners would like to pass along to other folks looking to DIY their yards is to give yourself plenty of time and tackle the project in small parts.
“I think the most important thing was breaking the project down into manageable tasks, and then figuring out the best order of those tasks. I also made some mistakes, so being adaptable to changes and adding tasks was key. I definitely needed the six-month extension in addition to the initial six-month period allowed; it took me about nine months total to complete the work.”
The other homeowner took almost a year to complete their project, but they now are basking in compliments from their neighbors.

Additional Facts on Mulches:
Wood chip mulch insulates 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. This makes the soil more sponge-like and better able to hold water. By installing 3-4 inches of mulch over bare dirt, weeds are reduced, the soil is enriched and new plants retain more moisture.
Another benefit of organic mulches is that they can visually accommodate a little bit of leaf litter, reducing the need for constant raking and clean-up. A thin top dressing of mulch added every two to three years keeps the landscape looking fresh and replaces the material that has broken down to sustain the soil. Organic mulches are lightweight, making them easy to transport in a wheelbarrow and spread with a rake.
Mulches are available in bags from most local garden centers (avoid the dyed ones as the colors will fade) and in bulk from several retailers in the Albuquerque area. When you buy from local bulk retailers, you are supporting the recycling of local organic materials that may otherwise end up in a landfill and contribute to greenhouse gas emissions. Buying bulk also means less plastic! Mulch is sometimes available at no cost from local tree trimming companies. In addition, Bernalillo County offers free mulch to residents who load it themselves at the East Mountain Transfer Station. County staff can load the mulch in your vehicle with a tractor for a $5 charge. The county also will deliver 30 cubic yards of mulch for $60, plus $2 a round trip mile for delivery. Mulches are a renewable resource that will improve landscape health and conserve water.
In areas of higher wind exposure or periodic inundation with water, use a wood chip mulch that is irregularly shaped and sized as the pieces will knit together better. This type of mulch can include recycled yard waste and tree trimmings as well as commercially available, locally processed wood products.

As homes around the Greater Albuquerque Area are converting their high-water-use turf grass to desert friendly xeriscapes, many are choosing to use wood chip mulch instead of gravel or other aggregate, which can be hot and allow weeds to pop up.
The Water Authority checked in on some recent xeriscape conversion projects. Two West Side homeowners with small backyards shared their grass transformation stories with 505Outside. Both homes had grass and gravel landscape. The decision to convert to a desert friendly xeriscape was an easy one, as one homeowner commented, “While I liked having grass, I couldn’t justify the water it took to keep the lawn healthy. I do enjoy not having to mow and feel much better about saving water.”
Both homeowners chose to use wood chip mulch. One homeowner learned through their contractor that shredded wood chip mulch is cooler than gravel and retains moisture around the plants. The second homeowner was used to the idea of mulch from their time living in New England.

The homeowners noted that mulch was easy to install and much less expensive than gravel, and they noticed that the mulch also was much cooler than the hot gravel. For these West Side homeowners, wind was their biggest concern. However, after living with the mulch for over a year, it’s only blown around a little bit and has been easy to sweep back into the garden.
One surprise for these homeowners has been the increase in wildlife. “We see whiptail lizards and ground feeding birds like robins, thrashers and roadrunners foraging for insects in the wood mulch.” Both agreed they do not miss mowing a lawn, plus they love the bonus of a low water bill. The Water Authority rebates were a huge incentive to make the change. There was definitely a learning curve for these first-timers to using a drip irrigation system, but it’s been easier than they thought, and their landscapes are low maintenance overall.

The Albuquerque metro area has a wide variety of landscapes. These include desert friendly landscapes, lush pollinator friendly xeriscapes and wildscapes or prairie plantings where native grasses and wildflowers bring the feel of a prairie to a yard and attract wildlife. Rain gardens are specifically designed to make the most of natural precipitation, while edible landscapes have garden beds or edible plants interspersed throughout them. Efficient turfscapes have smaller areas of turfgrass and diverse plantings. Conventional turfscapes, with large areas of cool-season grasses and high-water-use foundation shrub plantings, are no longer considered desert friendly landscapes. The term “desert friendly” now describes a variety of landscapes that include beautiful, diverse plantings with increased resiliency achieved through efficient watering.
Wildscapes or prairie plantings take advantage of natural landscape techniquess and plant choices that attract wildlife. These types of landscapes include native warm-season grasses and a mix of native and adaptive plants, including wildflowers.
A wildscape may be designed to rely more heavily on natural precipitation to sustain established plants than a xeriscape. Both natural precipitation and temporary irrigation are needed at first. Establishment in the grass areas often takes three years and possibly longer for trees. Monitoring and removing weeds is critical during this early period. Wildscapes also require less frequent yet deeper watering than a regular cool season turfgrass lawn.
Pro Tips for Irrigation of Wildscapes:
• Consider a mix of high-efficiency sprayers or rotors (for the native grass area) and drip irrigation or inline dripline (for shrubs and trees) on separate zones. Specific zones can be turned off after the plantings are firmly established.
• If you are using rotors or spray irrigation in native grass areas, make sure they will clear the tall grass. Use rotors with a high angle of throw or 12-inch to 18-inch pop-up sprayers.
• Leave the irrigation system in place, even if the plan is to rely on natural precipitation, so supplemental watering is available during times of extreme heat or drought.

This fruit tree thrives against a hot wall with southern exposure. Beautiful orange flowers appear in the spring. After lots of pollination work by bees, pomegranates trees are covered with uniquely shaped fruit. This stunner needs only 4 feet of space because it has upright growth. During harvest time in the fall, it puts on a yellow foliage show then goes dormant for the winter. Pomegranate trees take about two growing seasons to fully set deep roots and produce fruit.
As homeowners around the Greater Albuquerque area are converting their high-water use turfgrass areas to desert-friendly xeriscapes, many are choosing to use wood chip mulch instead of gravel, which can be hot, expensive and also very good at cultivating weeds. Gravel can use up to as much as 60% of the materials cost of a landscape transformation project.
The Water Authority checked in on some recent xeriscape conversion projects that use wood chip mulch. One of these homes was built in the 1950’s and is located in the near NE Heights, an area where the original landscapes for homes consisted of both front and backyards with Bermuda grass and large elm trees. The homeowners wanted to remove the grass in both the front and back of the house and create desert-friendly xeriscapes while retaining their mature trees. They became fans of wood chip mulch many years ago while living in Florida. “Wood chip mulch is easy to maintain,” explains the homeowner. "I do nothing to it except occasionally blow out whatever drifts into the swales and top dress it every couple of years with a thin layer of new mulch. Not only does it reduce the evaporation of moisture from the soil, it helps keep our property much cooler than rock because it doesn’t retain heat or reflect the intense light we get here. I also think the mulch along with the trees helps dull the sounds of the city.”
The mulch, which is laid down 3” to 4” deep, makes weeding much less of a task. Fewer things germinate in the mulch and when things do – in particular, the zillions of elm seeds that drop every spring — all that’s needed is to rake back the mulch layer, let it dry out for a day or so, and then rake it back into place. The seedlings dry up, die and become part of the mulch layer. The hardest part of the project, according to the homeowner, was removing the Bermuda grass. Due to the nature of its rooting system, the grass was completely eradicated before beginning the installation process. In this situation, the homeowner used an herbicide treatment to eradicate the grass. Since there are many options for eradication, we invite homeowners to take advantage of our free, ask-an-expert email service, AskAnExpert@abcwua.org, if you have questions about what type of lawn you have or any other questions about xeriscape transformations.
It’s been two years since their yard transformation. The homeowners say they noticed changes in the wildlife in their yard almost immediately. Fruit-bearing shrubs and wildflowers are allowed to go to seed, which means there are food sources for pollinators and birds most of the year as well as more cover in which critters can take shelter.
Since these homeowners moved to Albuquerque from a subtropical area, they did note that the one big lesson has been how much patience is required when undertaking a project like this in our desert environment. “The first year, most of what had been planted survived the winter, but a lot of things didn’t show much growth,” explains the homeowner. “I was a little frustrated. But this spring, things just burst forth – partially because of the amount of rain, but also because it simply takes that long for things to really establish a root system that can sustain significant growth.”
Sitting in their yard is more enjoyable now, say the homeowners, as the cooler landscape makes the outdoors more comfortable. They continue to learn from their landscape, picking up a few new irrigation drip skills along the way. They receive many positive comments from neighbors and are proud that their yard is an example of a healthy, sustainable and low-water use desert-friendly landscape.
