Develop a Mulch Master Plan
How much mulch does your landscaping plan need? To develop your mulch master plan and answer this question, you first need to understand the job it will perform in different areas of your watersmart landscaping plan.
- If you want to hold in moisture and keep down weeds: Use three to six inches of mulch on top of the soil
- If you want to maintain your planting beds: Maintain two to four inches of mulch on beds at all times
Master Tip: Keep mulch one to six inches away from plant stems. When mulch crowds them, it can cause plants to rot due to moisture.

For accurate results, check these numbers:
- Square footage of your landscaping
- Thickness of your mulch cover in inches
Take your square footage, multiplied by mulch thickness, and divide this number by 12. The result is the amount of mulch you need in cubic feet.
Example: 891 square feet of land, multiplied by one inch of mulch, divided by 12 = 74.25 cubic feet of mulch.
Avoid these mulch types around plants
Inorganic mulches don’t decompose to feed your soil microbes and keep your plants and garden healthy and thriving. There are also some organic mulches containing dyes or other chemicals. Others such as shredded redwood take a very long time to break down.
Master Tip – These are the types of mulches you should use only in areas without plants:
- Shredded redwood
- Dyed wood mulch
- Decomposed granite
- Gravel
- Rubber pellets
This article is part of a year-long series inspired by the 71-page Sustainable Landscapes Program guidebook. The Water Authority and its partners also offer other great resources for landscaping upgrades, including free WaterSmart classes at WaterSmartSD.org.
‘Mega-Miracle’ Will Be Needed to Overcome Dry February in Los Angeles
February is normally the wettest month of the year in downtown Los Angeles, when 3.8 inches of rain would usually fall. This year, next to nothing has fallen. L.A.’s rainfall to date has been 4.39 inches, less than half of normal for this point, which is 9.71 inches.
Colorado River Study Means It’s Time to Cut Water Use Now, Outside Experts Say
Less water for the Central Arizona Project — but not zero water. Even more competition between farms and cities for dwindling Colorado River supplies than there is now.
More urgency to cut water use rather than wait for seven river basin states to approve new guidelines in 2025 for operating the river’s reservoirs.
That’s where Arizona and the Southwest are heading with water, say experts and environmental advocates following publication of a dire new academic study on the Colorado River’s future. The study warned that the river’s Upper and Lower basin states must sustain severe cuts in river water use to keep its reservoir system from collapsing due to lack of water.
That’s due to continued warming weather and other symptoms of human-caused climate change, the study said.
Water Agencies Disagree on How Much Water San Diego Needs
The San Diego Water Authority thinks the region is going to need way more water over the next few decades, but the smaller agencies that buy water from them aren’t so sure.
Water Authority Helps Farmers Boost Water Efficiency
Agriculture is a rich part of San Diego County’s heritage and a foundational piece of the region’s economy, but it’s not easy to make a go of farming here given the hilly terrain, uneven soils and limited natural water supplies.
That’s where the San Diego County Water Authority comes in. The region’s wholesale water agency has funded more than 2,300 free irrigation system evaluations for farmers on more than 35,000 acres of avocados, citrus, field flowers, and other fruits and ornamentals since 1991.
Water Conservation Garden Growing Strong With New #FreeDayFriday Program
In a normal year, The Water Conservation Garden in east San Diego County provides resources and education for 88,000 children and families annually. Due to the coronavirus pandemic, meeting the Garden’s mission took a little extra effort and creativity.
To remain open after its initial closure and re-opening in June 2020, the Garden now charges a small admission fee. Thanks to the new #FreeDayFriday initiative, supported by a donation match through the Rice Family Foundation, more than $60,000 in contributions now allows the Garden to offer free admission on the second Friday of each month, starting February 12.

The Garden’s elementary school education program featuring Ms. Smarty Plants is now available online for grades K-2 and 3-6, including full lesson plans and video. Safely distanced Family Field Trips are also available for schools, homeschool groups, and individual classes.
“Our garden, not only is it an educational site, but we have classes that coincide with how to make what you see at our garden happens, where to buy the supplies, and how to do it,” said Pam Meisner, director of operations and education and founder of the Ms. Smarty Plants program. “We are the go-to place in San Diego for sowing beauty with low water use plants.”
“We can’t survive without water. But people don’t value that. One of our reasons being here is to show them the value of water and make that part of your life,” added Meisner.
Classes on sustainability, gardening, and art are currently offered online. Professional one-on-one phone or video consultations on water harvesting, and how to set up, retrofit, and maintain your irrigation or landscape are available by reservation through the website at thegarden.org/consultations

A task force of water agencies and municipalities conceived the Water Conservation Garden in response to six years of drought in San Diego County.
Otay Water District, Helix Water District, and Cuyamaca College kick-started the effort in 1990. By 1992, the San Diego County Water Authority, City of San Diego, and Padre Municipal Water District joined the effort, forming the original Water Conservation Authority.
The following year, the Grossmont-Cuyamaca Community College District approved the establishment of a 4.5-acre Water Conservation Garden adjacent to Cuyamaca College.
Helix Water District Demonstration Landscape Blossoms
The plants are thriving at Helix Water District’s demonstration landscape just eight months after the project was completed. The WaterSmart plants at the District’s administration office in La Mesa beautify the neighorhood while inspiring people to install sustainable, WaterSmart landscaping.

“Everything is growing in beautifully,” said Helix Water District General Manager Carlos Lugo. “We started with smaller plants to reduce costs and planned for growth. We’re happy to share this resource with our customers and community.”
Demonstration landscape includes water-wise gardens
The demonstration landscape includes three unique water-wise gardens on the streets around the building, including a Mediterranean garden on University Avenue, a desert landscape on Lee Avenue and a California native landscape along the building’s main entrance on Quince Street. Each garden started with smaller plants of varying colors, flowers and textures.

“The grasses in our native garden are filling in the mulched areas, creating a soft meadow-like appearance,” said Lugo. “We are also seeing the canopies of the Palo Verde trees expanding, and underneath, the succulents and agaves are blanketing the hillside, filling the landscape with color and texture.”

Plants provide wildlife habitat
The plants in all three of the gardens are adapted to San Diego’s climate and need half to a fifth of the water that a traditional lawn needs. In addition to requiring less water, WaterSmart landscapes also require less maintenance and provide habitat for local wildlife like honeybees, birds and butterflies.
In each garden, plant markers provide the name of each plant and a QR code, which when scanned with a smartphone, provide each plant’s name, sun and water needs, mature size and photo.
Customers can also use the district’s interactive webpage to make a list of their favorite plants and download each garden’s design plan. Information on efficient irrigation and rebate programs is also available.

The project was completed in June 2020 and partially funded through a grant from the Metropolitan Water District of Southern California.
Helix Water District provides water treatment and distribution for 277,000 people in the cities of El Cajon, La Mesa and Lemon Grove, the community of Spring Valley and areas of Lakeside – east of downtown San Diego. Helix is also a founding member of The Water Conservation Garden, a nearly six-acre water-wise demonstration garden in El Cajon.
