Mountains Inspire Winners of San Dieguito Water District 2023 Landscape Contest

Large trees were the driving force that led Encinitas homeowners to remove grass and create a vibrant, low-water use landscape. The waterwise transformation won the San Dieguito Water District 2023 Landscape Makeover Contest.

Rick and Melanie Cullen had a yard with grass with large shade trees. But the roots of their three large Liquidambar trees were damaging the driveway and the grass, which motivated the couple to remake their landscape.

“San Dieguito Water District is proud to recognize customers like the Cullens, who create beautiful and resilient landscapes while making efficient use of their water,” said Isam Hireish, general manager of San Dieguito Water District.

The Cullens wanted to plant a drought-tolerant, water-wise yard that would be easy to maintain, beautiful, and hold up to their frequent travel schedule.

“My inspiration was to create a water wise, drought-tolerant front yard that also provides us a beautiful yard as if we were in the mountains,” said Melanie Cullen. It started with taking existing small landscape rocks and repurposing them into a natural dry streambed feature.

Plants were selected that would thrive in the coastal San Diego County environment. The invasive Liquidambar trees were replaced by Blue Ice Cypress, Forest Pansy Red Bud, and dwarf Deodar Cedar trees. Colorful drought-tolerant flowering shrubs and perennials including Coastal Woolybush, salvias, echinaceas, Texas primrose, heronsbill, columbine, Grevillea ‘Mt. Tamboritha’ and ‘Sour Grapes’ Penstemon provide habitat for pollinators.

Fragrant ground cover

Grasses including Pennisetum ‘Fireworks’ and Acorus ‘Variegated Sweetflag’ add to the plant palette. Creeping Thyme and trailing Rosemary are used as colorful, fragrant ground cover.

A highlight: one dozen Azaleas create a woodland flower look. Cullen says they bloom when other plants aren’t flowering.

“One might think they are water hogs, but they get the same water as everything else and bloom quite a bit throughout the year,” said Cullen. “It was a matter of choosing the right type of Azalea (Red Bird and Alaska White).”

Drip irrigation system saves water

The Cullens used a drip irrigation system that encircles each plant individually to direct water to the specific plant. They already had a smart irrigation controller which is still in use. A remote moisture sensor was added allowing the homeowners to monitor the ground moisture at the plants and then adjust watering for the yard.

Three to four inches of bark mulch helps retain irrigation, which has worked “extremely well.”

Tapping rain

Melanie Cullen says the irrigation was turned off completely from January through May due to generous rainfall. “Presently, we only need to water once every one to two weeks for 20 minutes,” she said.

“I join our Board of Directors in recognizing the leadership of the Cullens and commend them for taking proactive steps to improve our community’s resilience to a changing climate,” said Isam Hireish, General Manager of San Dieguito Water District. “I encourage all customers to utilize water more efficiently and take advantage of the various water-saving incentives we offer.”

In the months since the landscape makeover, the Cullens report all their original goals were met. “We love sitting in our front now and watching the many hummingbirds that also love our yard,” said Melanie Cullen.

In Los Angeles, the Grass Isn’t Always Greener This Year

Erin Brockovich made her name decades ago as an environmental activist who exposed corporate wrongdoing that polluted drinking water.

So she felt a bit defensive when a television reporter asked how her name landed on a list of water guzzlers during a dire California drought. At one point last year, she received a $1,700 bill for two months of water and fines.

Ms. Brockovich ultimately decided she had to get rid of her lawn, a central part of the backyard oasis she had built over more than two decades living in Agoura Hills, a suburb of large homes with immaculate yards about 40 miles northwest of downtown Los Angeles. She replaced 3,100 square feet of grass with high-tech artificial turf.

Best Options For Turf Removal

Once you’ve finalized your landscaping plans, you’ll have some demolition work ahead of you, including the existing turf you plan to remove or replace. Removing turf presents choices about the best way to accomplish this task. Learn more about turf removal options and understand the steps before you begin.

Reclaiming an area of unwanted turf requires diligence. No matter what method of turf removal is used, plan on routine maintenance, including weeding or herbicide application, as often as every two weeks for the first three months after your take your turf out. Some tenacious warm-season grasses might give you a battle for even longer.

Options for Turf Removal

Natural turf removal. A natural way to remove turf and preserve the soil’s ecology is to strip the turf and water the area for the next two weeks to encourage grass to re-sprout and hand pull all new growth.

Sheet mulching. Rather than removing turf and taking it to the landfill, you can compost it in place. First, remove several inches of turf and soil from the edges near your hardscape. Wet the turf area and cover it with several layers of newspaper. Water again and cover with cardboard. Water again and cover with three inches of shredded mulch.

If you can invest the time, allow several months for the soil microbes to decompose the turf and turn it into friable soil for plants.

Solarization. Another alternative is solarization. This works best in the spring or summer. Turf areas are covered with rolls of plastic. Sun exposure heats the soil and kills the turf and weed seeds. The cover must be airtight with no holes and left in place for six to eight weeks. However, this method will also kill beneficial soil microbes. Using this method, you must follow up and apply compost or other soil amendments to restore the soil’s healthy biology.

Turf removal with herbicide. If you choose to use an herbicide, consult with your local landscape supply store and read the manufacturers’ label for best use practices and safety considerations. Since Bermuda grass and some other grasses are dormant in the winter, they must be treated when actively growing in the remainder of the year (May to October).

Grading. When the turf is removed, you need to grade your property. Set the soil level to direct water away from the house. To help slow down water runoff from your garden, try creating small depressions away from structures, walls, or paving where water is allowed to pool and slowly percolate into the soil. The more you slow the water down or hold it on site, the more you improve water quality in your area and downstream at local beaches.

Reduce runoff. Runoff carries with it soil particles and pollutants. Reduce runoff by using mulch.

Prep For Success

Now that you have removed unwanted turf and other plants, it is time to condition your soil.

Soil amendments should be selected based on your soil analysis recommendations. Till them into the top layer of soil. Compost (15-30% by volume), gypsum, and fertilizer are typical amendments in arid climates like San Diego County.

The goal is to achieve healthy soil containing microbes which feed plants, improve drainage, and increase the natural water holding capacity of the soil.

Most residential water use in San Diego County is used outdoors, primarily to water landscaping. When yards contain a large amount of turf, it can significantly increase overall water consumption. This is why conservation education efforts focus on replacing turf.

By showcasing how beautiful landscapes without grass can be through the WaterSmart Landscape Contest, homeowners can share their creativity and demonstrate how attractive WaterSmart landscaping can be.

“San Diego County homeowners are moving toward beautiful, sustainable landscapes and away from water-intensive lawns as the default choice,” said Joni German, San Diego County Water Authority water resources specialist. “Through ongoing education and through the examples people see around them, homeowners can see that water-efficient landscapes can be beautiful, lush, colorful, and thrive in our region. This contest is a great way to showcase the efforts homeowners regionwide have made to create these incredible outdoor spaces.”

Soil Microbes-your lawn-healthy soil-Conservation Corner

Remove Your Lawn the Healthy Way

The day has come to replace your thirsty, water guzzling grass. Before you remove it, plan your process carefully to leave only healthy living soil as the foundation for a beautiful, thriving new landscape.

Don’t just turn off your irrigation and let your grass turn brown as it dies off. Healthy microbes in your soil will die off along with the lawn. You want to work with those microbes to help create healthy soil for your new plants.

Instead, keep your grass moist until you remove it. It’s also a lot easier to remove fresh, moist grass than to try and pry out dead dry grass and weeds in rock hard, dry soil.

Stay cool and save healthy microbes

It’s tempting to remove your lawn through solarizing. Solarizing is sometimes used as a way to remove grass without chemical treatment. Instead, a covering such as a heavy black plastic tarp is placed over the grass. Sunlight heats the covering, which broils and kills the lawn through high temperatures. This heat also kills existing healthy microbes you need for healthy soil. It’s possible to artificially replace them with compost, but you need to invest in a lot of compost to restore the good microbes when grass is killed off and removed with this method.

When soil is solarized, it’s sterilized. It remains like this for weeks. Worse, it really doesn’t do much good. Opportunistic weeds move in quickly to try and take over the ground. These weeds don’t grow from existing seeds in the soil. These have usually been killed off. But without any competition, new weeds can arrive in a flash, and nothing prevents them from taking over.

Stay loose

If you use heavy equipment to remove your old turf, the equipment’s weight will compact your soil underneath. You need to avoid this. Minimize the use of heavy equipment and use walk-behind equipment with hand tools where possible. Use a tractor or scraper only where necessary.

Avoid tilling your soil. Tilling soil breaks up and kills your soil microbes. Without the microbes, you’re guaranteed to have those weeds pop up for a long time until new soil microbes develop.

Protect your trees planted in areas where the grass is removed. The key is not to damage their roots. Heavy equipment can destroy roots established by a healthy shade tree. Steer clear of the canopy area under the tree’s branches. Its root structure extends all the way out to the drip line at the edge of the leaves. Irrigate your trees generously during the removal process to help minimize root shock.

Save landscape trees from shock

Creating a DIY self-watering bucket will help prevent landscape trees from going into shock after surrounding turf is removed.

When your new sustainable landscaping is installed, your previously existing trees may go into shock when irrigation is reduced overall in your garden. While it’s one of your watersmart landscaping goals, keep the trees watered during the first year after your grass is removed.

A good way to hand water your trees: Punch holes in a five-gallon plastic bucket. Fill the bucket, and set it down at the edge of the tree canopy, and let the water slowly seep into the ground. Repeat the process three to four times to water your beautiful mature trees. This mimics the natural rainfall Mother Nature provides.
