It’s summer! This is the garden’s harshest and most challenging season of the year, Southern California’s gardening equivalent to winter in most parts of the country.
Pay close attention to how much, how long and how often to water different kinds of plants in your garden.
Your goal is to water just right — not too much, not too little — for each.
The slope of a 1920s La Mesa home went from a drab lawn to lush floral color with climate-appropriate plants, winning recognition from the Helix Water District as the runner-up in its 2023 WaterSmart Landscape Contest.
A new state task force charged with investigating the local effects of the drought-depleted Colorado River and recommending legislation to respond to the water crisis met for the first time this week.
Members representing different river interests who gathered for the first meeting on July 31 shared hope that they would find common ground as they collaborate on possible policies, tools and solutions to help respond to the Colorado River, which has been depleted by a 20-year megadrought, climate change and overuse.
We’re living in a pivotal moment in history, on the cusp of either sinking into a dark period of growing poverty, accelerating ecological destruction, and worsening conflict, or moving forward to a new age of equity, sustainability, and stewardship of the only planet in the universe where we know life exists. I believe a positive future is not only possible, but inevitable, but solving our current crises and moving along the path to that desired future will require new, concerted, and sustained efforts.

The contest promotes beautiful, water-efficient landscapes and rewards people for their inspiring gardens. Joanna and Larry Henning created the country garden with climate-appropriate plants.
The Hennings bought the property in La Mesa‘s historic downtown area in 2017. Its landscape was covered in weeds and poorly maintained trees. The couple wanted a new landscape that would fill in the expansive slope and be water efficient while staying true to the character of their home.

Planting an area this large with new plants can be expensive. But the couple were creative and resourceful, sourcing their plants for the new landscape design. Larry Henning used succulent cuttings from friends and family to plant most of their new landscape.
They supplemented the landscape with carefully chosen specimen plants, including protea, sages, and plumeria. These choices create the landscape’s variety of interesting shapes and colors. Five years after starting the project, even the slowest growing plants are fully grown and have transformed the landscape.

The landscape uses water efficiently to provide enough water for the plants to flourish without waste. Watering schedules are controlled using a smart weather-based irrigation controller. It automatically adjusts for rain and weather changes. Plants receive water from inline drip irrigation with pressure-compensating drip emitters.
Pressure compensation is essential for sloped landscapes because it maintains even watering rates all along the slope and prevents overwatering areas at the bottom of the landscape, where pressure is higher. Mulch covers the drip system, which protects the soil and slows evaporation.

The landscape delivers ample curb appeal. From the street, trees frame the landscape, filled with shades of green and pops of color. Viewers can also see agave, cacti, and dozens of other succulents. Many display long cones of flowers. From the front patios, the garden provides a tranquil space for the family to enjoy.
District officials selected the landscape for special runner-up recognition due to its impressive transformation and efficient use of color and irrigation.
Helix Water District holds its landscape makeover contest annually. Entries are accepted starting every February through mid-May. For entry information, go to landscapecontest.com.

Santee homeowners Edie and Tate Thomas created a beautiful landscape with California native plants to save water, beautify their home, and support the region’s wildlife. Their effort won the 2023 Padre Dam Municipal Water District landscape makeover contest.

In 2018, the couple began working on their makeover project. Edie Thomas is an architect, and Tate Thomas is a contractor. They took advantage of their building and design skills by creating a topography to capture and preserve the rainwater falling on their yard.
Their landscape is irrigated through underground rock ravines that collect rainwater in a rock-lined underground cistern reservoir which flows water to plants through gravity. They also buried large unglazed clay pots in their yard called ollas, which have above-ground access points to refill them with water. Plants wrap their roots around the porous ollas, which seep water out as needed, watering the plants with minimal water loss.
Edit Thomas advises other homeowners to do the same with their landscape topography.
“I always recommend people visualize a single drop of rainwater falling at the highest point of your landscape,” she said. “Watch where gravity takes that raindrop and plan your landscape around that flow.”
The pair also use drip irrigation about once a month along with occasional hand watering during extended dry periods.

Long nature walks and information from the California Native Plant Society inspired the Thomas’s to use native plants for most of their landscape, mixing colors and texture to be visually appealing. They have been richly rewarded with an ecosystem of butterflies, caterpillars, bees, birds, and bunnies. They describe their design concept as “playful chaos.”
The sidewalk in front of the garden is designed to be a community space for those walking by. The large California Coastal Live Oak provides shade to the retaining wall, designed as a place to sit and rest. Visitors can browse through books from the couple’s Little Free Library. Water-efficient herbs growing in the planter boxes under the tree are offered to those who pass by.
Edie and Tate Thomas spend most evenings on their patio, enjoying the space and watching their ecosystem thrive. They look forward to watching the plants grow and mature in the coming years and even decades.
“It’s so rewarding to see people come by and rest in the shade or take some rosemary for their dinner,” said Edie Thomas. “I love that we get to give a small square of land back to nature and that our neighbors enjoy it as much as we do.”

More than a year after instituting the strictest water conservation orders Los Angeles has ever seen, the L.A. Department of Water and Power announced Monday that it was loosening watering rules for its 4 million customers. Effective immediately, all Angelenos can return to three-day-a-week watering schedules after being placed on two-day-a-week limits in June 2022, the agency said.
Free water use surveys offered through the Metropolitan Water District of Southern California provide both residential and commercial customers with recommendations to improve landscape and indoor water use efficiency. The surveys are available throughout Southern California, including San Diego County.
Free water use surveys offered through the Metropolitan Water District of Southern California provide both residential and commercial customers with recommendations to improve landscape and indoor water use efficiency. The surveys are available throughout Southern California, including San Diego County.
The San Marcos Unified School District took advantage of the opportunity for water use surveys at 17 of the district’s school sites. It is among the largest single regional customer survey to date.
Austin Black, water conservation specialist for WaterWise Consulting, oversees the audit project.
“We are auditing the irrigation system of all of the schools with more than one acre of landscape area [for this project],” said Austin. “The survey tests all the different irrigation zones, looking at the type of landscape and plant material, and weather factors. We take all that data and calculate potential water savings based on our recommendations.”
Recommendations may include converting to drip irrigation, installing smart controllers, and replacing grass with a WaterWise landscape with a more efficient watering system.

Surveyors also adjust existing sprinklers for maximum efficiency and compile a list of repairs and upgrades to improve water use efficiency.
“In our effort to be good stewards of all resources used by the district, the decision to participate was an easy one,” said Ted Norman, SMUSD executive director of maintenance and operations. “We will review all our options and implement as many of the recommendations as we can. It’s a win for everyone.”

In one example, the audit report provided to the district for the San Marcos Elementary School estimates that implementing the recommended water-saving measures can reduce landscape water use by approximately 252,000 gallons. Project cost savings are $1,363 annually. If similar savings are achieved at 17 schools, this reflects significant net savings to taxpayers.
“We will submit the reports, and the district can make the changes as they wish,” said Black. “The goal is to create water savings for the entire district and the [water] agency as well.”
MWD can assign a consultant to work with SMUSD and other customers after the audit is completed to help prioritize changes recommended in the survey. The consultant services are free.

Homeowners can also take advantage of free surveys. Residential surveys look at both indoor and outdoor home water use.
“It’s a comprehensive survey checking for leaks and ways we can make the household more efficient,” said Black.
Along with irrigation improvements, the residential audit reviews the replacement of inefficient plumbing fixtures and other simple adjustments.
