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.

County Fair Exhibits Delight Visitors with Low-Water Use Landscaping

If you’re ready to move ahead with plans to create a water-efficient landscape, the San Diego County Fair is a good place to start. There are several award-winning examples of creative low-water use and native plant gardens at the fair’s popular Paul Ecke Jr. Garden Show exhibit area. (The San Diego County Water Authority has partnered with the state’s Save Our Water to sponsor a booth at the exhibit area).

This year, the Water Authority sponsored the California Native Plant Society exhibit, which received multiple category awards:

  • First Place, Paul Ecke, Jr. Garden Show Theme Award
  • Edwin Frazee Donated Award for best use of flowering plants
  • San Diego Floral Association for best landscape entry by a non-commercial, non-professional group
  • Master Gardener Association Earth-Friendly Gardening Donated Award
  • Plants of Distinction – four ribbons awarded

Dunn explains how Californians are changing their vision of the ideal home landscape design.

“Our vision of landscapes featuring predominantly turf and a border of hedged plants is changing. In its place, we’re upgrading our landscapes with water wise plants, both native and also waterwise plants from Australia and South Africa. All these plants bring in more color while inviting birds, bees, butterflies, and hummingbirds. All this and less water to help them thrive,” said Dunn.

Dunn says California gardeners are adjusting to the seasonal rhythms of native plants, which may bloom for short periods and then become dormant. “You can plant so that there’s always a stunning showstopper in your garden. It’s about putting the right plant in the right place. It’s changing the way we see landscaping,” explained Dunn.

“Some native plants are beautiful for part of the year, and then they go dormant. That’s how nature works. Like a butterfly, they go through different stages.”

Low-water use gardens suit many design styles

Dunn said low-water-use landscapes offer many different styles to suit individual tastes and needs, similar to interior design styles. “Everyone’s got their look and their style. It’s the same with plants. There are so many options and choices with these plants. There’s something for everybody.

“If you’ve got kids and dogs, you may need grass. But if the only person walking on the grass is the person mowing the grass, you likely don’t need the grass. There are countless beautiful native and California-friendly plants you can place in your garden that will bring you entertainment and joy,” said Dunn.

Fun garden display educates with humor

Dunn won the Edgar Engert Educational Merit award for her own individual display, a whimsical, colorful waterwise plant display she titled the “Groovy Garden.” Dunn called it “a dream come true.”

“It’s all about Flower Power and inviting birds, bees, butterflies, and hummingbirds,” said Dunn. “About 25% of the plants are native.”

In addition to features like a dry streambed, rain chain, and rain barrel to demonstrate rainwater capture, Dunn repurposed colorful thrift store and garage sale finds to educate through imagination and humor and make a lasting impression.

WaterSmart and WaterWise

“I created different rooms including a bedroom, kitchen, living room, and even a bathroom,” said Dunn. “Everything is upcycled including my pink toilet. It is there to remind people that toilet leaks are the number one cause of water loss. One running toilet can flow up to 200 gallons an hour, enough water to fill a pool in four days.”

Dunn used humorous puns with her signage. “My goal is to bring them in with the gorgeous plants and while they’re there, educate them about irrigation, mulch, composting, and more,” she said.

Choosing Your Best Irrigation Method: Spray or Drip

Your choices in irrigation methods come down to spray or drip systems. Spray irrigation emits water in an overlapping pattern. Drip irrigation delivers water directly to the roots of plants. This question is more important than ever during a drought cycle. How do you decide which meets the needs of your landscaping?

The case for spray irrigation

Spray irrigation can be an efficient way to irrigate large landscapes with groundcover or uniform plant materials like lawns or meadows.

Spray systems apply water in gallons per minute, so if you know the application rate of each spray head, the distance between the heads, and the pressure of your system, it is relatively easy to figure out how much water is applied every time you run your irrigation.

Low volume spray heads apply water at about one-third the rate of conventional spray heads. Newer spray irrigation heads have improved spray with heavier droplets more resistant to wind. Landscaping with grade changes using spray heads should have check valves installed to prevent water flowing out of the lower point heads.

Challenges of spray irrigation include narrow areas surrounded by hardscape or irregular patterns. Irregular patterns are particularly challenging because spray irrigation requires head-to-head coverage to be efficient. Odd-shaped areas may be under or overwatered. High-volume spray heads that emit water at a much higher rate than the soil can absorb should be replaced.

The case for drip irrigation

Drip systems apply water in gallons per hour, so they often need to run for longer periods of time than spray systems. But the actual run time must always account for precipitation rate and runoff.

Installation of subsurface systems (under at least two inches of mulch) is the most efficient way to irrigate nearly every type of garden area. Since the tubing is flexible, it can accommodate a variety of irregularly shaped areas or rectangular areas when laid in a grid pattern, and in rings you can easily expand as trees or shrubs grow.

Challenges of drip irrigation include the application of water too quickly for your soil to absorb. This needs to be considered when dripline grids are installed. Drip irrigation operates the most efficiently at low pressure (between 15 and 30 PSI). To achieve optimal performance, pressure regulation either at the valve or at the point of connection of the dripline to the buried lateral lines must be used. It is also essential to install some type of filtering system to keep the emitters from getting clogged.

Smart Landscape Irrigation Tips Save Water

During drought, it’s more important than ever to conserve water used for irrigation. When you follow just a few smart landscaping irrigation tips, you can get the most from every drop of water applied to your landscaping.

Don’t overspray your landscaping

Watch your irrigation while the system is running. Check to make sure sprinkler heads aren’t spraying water onto sidewalks, patios, or structures.

If water is being applied too fast for your soil to absorb, runoff will occur. This needs to be prevented.

Puddling and pooling water may be an indication your water is being applied too fast or too often. Adjust your system until this isn’t happening anymore.

Repairs to broken pipes and sprinkler heads should be made immediately, or your system should be turned off until those repairs can be made.

Eliminate runoff with cycle and soak programming

Watch how quickly runoff happens when running irrigation. This is the maximum run time for your irrigation controller in a particular hydrozone.

Divide the total irrigation minutes recommended for the specific hydrozone condition into shorter blocks of time before runoff starts. For example, if you should irrigate for 15  minutes but runoff starts within five minutes, irrigate in three five-minute cycles. Allow a 30-minute rest period in between irrigation cycles.

Hand watering that works

Hand watering is especially good when your garden is getting established. You can spend more time watching your plants to be sure they are flourishing in the early stages.

When your landscape plants are new, you may need to water more frequently because roots are shallower. Roots on a newly planted one-gallon plant are only four to ten inches deep. This is why it’s a smart idea to plant during the rainy season.

Before hand watering, look at your plants. Do they appear droopy? Is the soil very dry? If so, give the plants a good drink. Don’t water more than two days in a row. Let the soil dry out completely before watering again. Overwatering and underwater symptoms can be similar.

Once your plants are established after the first year, your sustainable garden will  not need watering more than once or twice a month – if at all. Stop watering after the first seasonal rains begin and let nature take over.

The WaterSmart Landscape Contest is an opportunity for homeowners to showcase landscape designs focusing on beautiful alternatives to traditional turf-oriented designs. Entries in the makeover competition are judged on five qualities:

  • Overall attractiveness
  • Appropriate plant selection
  • Design
  • Appropriate maintenance
  • Efficient irrigation methods

Native plants and a natural habitat

Rodriguez and his wife participated in a free Water Authority WaterSmart Landscape Makeover Series course. It provided the foundation allowing them to embrace a design replacing the lawn. They also attended several native plant workshops hosted by the San Diego Chapter of the California Native Plant Society. The family were attracted to gardening with native plants due to their low water and no fertilization needs. They also liked the added benefit of creating a natural habitat for pollinators and birds.

The transformed landscape now includes several manzanitas and large Ceanothus shrubs in the back yard, which reminds Paul Rodriguez of hikes in Mission Trails Regional Park. The front yard adopted a California Coastal Sage scrub garden habitat. It only requires hand watering twice a month during the dry season.

It is a pollinator’s paradise with sages, buckwheats, and verbenas that attract birds and bees. Milkweed provides a food source for endangered Monarch butterflies. Milkweed leaves are the only food monarchs will eat. They also lay eggs on the undersides of the leaves. Striped caterpillars feed on the leaves as they develop.

Waterwise Tree Choices for WaterSmart Landscaping

Trees are the single most valuable addition to your waterwise landscaping. Trees create improved water quality, resulting in less runoff and erosion. They also improve air quality and provide habitat for insects, birds, and animals. Healthy, mature trees are so beneficial, they can add an average of 10% to a property’s overall value.

When thoughtfully placed around buildings, the cooling and insulation created by a tree’s canopy can reduce air conditioning needs by 30%, and can save 20-to-50% of the energy used for heating.

When thoughtfully placed around buildings, the cooling and insulation created by a tree’s canopy can reduce air conditioning needs by 30%, and can save 20-to-50% of the energy used for heating.

Before you choose landscaping trees, research their size at maturity. When you first purchase it, it’s in a 15- or 25-gallon container and it’s hard to imagine it growing above your roofline. But a small tree can become a 30-foot tall tree with a 30-foot wide canopy of branches in a few short years. If you select a large tree species, it could be 70 feet tall and equally as wide.

Ensure tree placement gives you a sufficient distance away from your home or other structures. Small trees (30 feet wide or less at maturity) should be placed no closer than 10 feet. Large trees (70 feet wide or more at maturity) should be planted no closer than 20 feet from a house.
