How to Choose Plants for Landscape Microclimates

/in , /by

Every garden has completely different cultivation characteristics, even those located in the same general climate zone. For example, there will be areas where plants will flourish.

Numerous features affect your growing conditions. Structures, walls, fences, and other plants can affect the amount of sun and shade in a garden. There can be hills and hollows in your front yard that may collect cold air. Or, because your property is sloped, you don’t get frost when your neighbors do.

Individual microclimates may differ significantly from the general climate of an area. To be sure you match the right plant choices to your conditions, you need to identify and map these microclimates. Start by walking around your property at different times of day. Observe conditions and take notes.

Choose plants that will thrive

Determine which plants will work in your new garden, and which should be removed or avoided. Outline the canopy area of the plants being retained. Note the name, general size, and health of the plants.

Do any of these plants seem “unthirsty?” Many plants can thrive on less water when they are well established, with deep healthy roots. Old rose bushes and large shade trees are two good examples. These drought-tolerant plants are worth keeping if possible, especially if they are mature.

Note sun and shade patterns

Mark the areas that receive sun all day, and areas that are shaded all or part of the day. Also note which areas receive only partial sun, or a few hours of direct morning sun, midday sun, or late afternoon sun.

In choosing landscaping plants, make sure to select those that are appropriate to the sunlight patterns of the garden. Plants marked as “full sun” will not be happy in full shade, and vice versa. Don’t work against their requirements.

Group plants for similar needs

Group plants with similar water requirements together. Make sure plants with different water needs are not combined. Some sun-loving plants have moderate water needs, and some have very low water needs. If these are mixed together, one will always suffer if the watering routine works for the other types.

Attracting Pollinators to Your Garden

/in , /by

Flowering plants rely on insects, birds, and other creators for pollination. In turn, plants attracting pollinators feed and house beneficial insects like bees and butterflies, and nectar-loving birds like hummingbirds.

Some bugs eat too much, destroying their plant hosts and spreading disease. Other beneficial insects fight off the destructive species, eating them or disrupting their reproductive process.  Birds, bats, and lizards help too, consuming pests both large and small.

Nature provides checks and balances in a garden. You can attract insects and creatures which will help maintain the health of a garden without pesticides.

Choosing a wide diversity of plants in your landscape can help attract helpful insects and predators on a regular basis. They improve the resilience of the garden and reduce the need to use chemicals for pest control.

To attract more garden helpers, create habitat for them. Consider adding a nesting box for bees. Leave a small rock pile for lizards to inhabit. Put a large tree branch in the garden and let it decompose naturally.

Planting a Butterfly Garden

Numerous plants attract pollinators and support the life cycle of butterflies, including the threatened monarch butterfly.  Plant several in the garden to help the larvae and caterpillars as well as the full-grown, nectar-seeking adults. Some good choices:

  • Narrow Leaf Milkweed (Asclepias fascicularis)
  • Island Alum Root (Heuchera maxima)
  • San Miguel Island Buckwheat (Eriogonum grande var. rubescens)
  • Cedros Island Verbena (Verbena lilacina)
  • Island Bush Snapdragon (Gambelia speciosa)

What’s The Buzz?

Not all ground needs to be covered in mulch. Try designating a five to ten square foot patch of open soil around plants for ground-nesting bees and insects, especially if your garden contains San Diego native plants. Succulents don’t like mulch right up against their stems, for example. Create a landscape where plants and pollinators work together

Water Authority Wins Four Awards for Outstanding Projects

/in , /by

The American Public Works Association and American Society of Civil Engineers recently presented the San Diego County Water Authority with four awards for construction projects that exemplified outstanding skill, dedication and collaboration from staff in many departments. All of the projects were underway or completed during the COVID-19 pandemic, and project teams navigated shutdowns, adapted to health and safety restrictions, and overcame many other uncertainties – in addition to typical challenges encountered during construction projects.

1) APWA Project of the Year: Northern First Aqueduct Structures and Lining Rehabilitation

With extensive coordination between the Water Authority’s Asset Management, Operations, Maintenance, Right of Way, Water Resources, Engineering and Public Affairs teams, the First Aqueduct rehabilitation project was completed in early 2021. Significant work had not been performed on the First Aqueduct since the completion of Pipeline 1 in 1947 and Pipeline 2 in 1954. The Operations and Maintenance Teams worked closely with multiple member agencies to ensure no impacts to water deliveries over the extended shutdowns required to reline both Pipelines. These extended shutdowns allowed the Asset Management team to inspect 27 miles of pipeline along the aqueduct using innovative technologies – the first time this had been done in nearly 75 years.

“Since the project included more than 35 work sites spread out over 15 miles, many in rural areas of the county, we collaborated closely between different departments and member agencies to ensure that water service was not disrupted,” said Emma Ward-McNally, Water Authority engineer.

2) APWA Honor Award: Vallecitos 11/Vista Irrigation 12 Flow Control Facility

This new facility replaced the existing Vallecitos 2/Vista Irrigation 1 facility that was built in 1954. The Water Authority’s Operations and Maintenance team worked closely with the Engineering team to develop a construction sequence to build the new facility while maintaining water service to member agencies.

“A meticulous level of detail in the design process allowed for the project to be completed with minimal changes during construction,” said Jim Zhou, Water Authority senior engineer.

3) APWA Honor Award: San Diego 28 Flow Control Facility

The new flow control facility replaced the San Diego 12 flow control facility. The Water Authority’s Right of Way team worked closely with the City of San Diego to acquire property rights for the facility. During construction, electrical and rotating technicians from Operations and Maintenance provided support to ensure that the facility was constructed correctly and that electrical relay protection was coordinated when connecting to San Diego Gas & Electric.

“The new facility repurposed an existing building at the site, but it was forward-looking – the project included the installation of a second pipe train for a future inline hydroelectric turbine,” said Aaron Trimm, Water Authority senior engineer.

4) ASCE Award of Excellence: Pipeline 5 Emergency Repair

After nearby Pipeline 4 was repaired in late 2019, the Asset Management team inspected Pipeline 5 in early 2020, and found it needed repairs as well. Multiple Water Authority departments and teams collaborated to launch the emergency repairs on Pipeline 5, despite the uncertainty of the growing pandemic. The Engineering Contracts group executed five contracts and task authorizations for design, construction and inspection within a few weeks to make the project happen, and the work was completed in April 2020.

“The project was a true team effort that required collaboration from multiple departments to ensure that the emergency repair could be completed even as the region was shutting down due to the pandemic,” said Colin Kemper, Water Authority senior engineer.

Olivenhain Municipal Water District-CWEA-award-water recycling

Recycled Water Facility is Plant of the Year

/in , /by

Olivenhain Municipal Water District’s 4S Ranch Water Reclamation Facility is the California Water Environment Association‘s Plant of the Year.

The District’s Board of Directors accepted the award at its May 19 meeting from California Water Environment Association San Diego section. The Plant of the Year award acknowledges OMWD’s accomplishments in compliance, innovative practices, and cost‐effectiveness.

“Our board is thrilled that 4S WRF has been recognized for industry‐leading procedures and techniques to produce high‐quality recycled water, increase water reliability, and operate safely, effectively, and economically,” said Olivenhain Municipal Water District Vice President Kristie Bruce‐Lane. “We need to focus on keeping water affordable and accessible to everyone. Diversifying California’s water portfolio by investing more in recycled water is a critical strategy in doing so, now and for our future generations.”

Recycled water

OMWD’s 4S WRF can produce up to two million gallons of recycled water each day. This alternative water supply is used for irrigation purposes at schools, parks, golf courses, streetscapes, and homeowner association common areas in the southeastern portion of OMWD’s service area.

“We appreciate the work of CWEA to advocate for realistic regulatory requirements for water agencies, helping us to maintain affordable rates for our ratepayers,” said Lane. “The way to move forward is by working together to create a thriving California that has enough fresh, clean and affordable water for people, food, and the environment alike.”

Proactive maintenace of infrastructure

4S WRF operators inspect and maintain more than 85 miles of sewer collection system pipelines, as well as equipment at the facility, lift stations, a 410-acre-foot storage pond, and a one-million-gallon reservoir. Proactive maintenance is also a priority, helping to avoid costly emergency repairs and ensuring continued wastewater and recycled water services for customers.

This is the second time in three years OMWD has won the San Diego section award. In 2019, 4S WRF was also named California’s “Plant of the Year” by CWEA’s state office.

Founded in 1927, the California Water Environment Association is a nonprofit association of 9,000-plus professionals in the wastewater industry. The association trains and certifies wastewater professionals, disseminates technical information, and promotes sound policies to benefit society through protection and enhancement of our water environment.

Enjoy Urban Farming While Being Water Smart

/in , /by

Many San Diego County native plants and herbs have fruits and leaves you can harvest. They can be mixed into any climate-appropriate planting design. You don’t have to be a farmer to grow and enjoy them in your sustainable landscaping.

For the health of your urban farming crops, consider employing organic growing methods including sheet mulching and integrated pest management. This will ensure the health of your soil, your crops, and the people who eventually eat and enjoy them.

Check local drought ordinances in your area to confirm watering schedules permitted for edibles, which may be more flexible during the most active growing period. Because the San Diego region has a mild, warm climate throughout the year, you can plant most fruiting trees just about any time of the year. Citrus trees generally do best in our area when planted in May or June, but it is possible to plant them earlier or later in the year as long as there is no nighttime frost.

Arrange the urban farming area in your landscaping to take advantage of their irrigation needs in a designated area. If the rest of the landscaping is using minimal water, you can spare extra irrigation for your fruits and vegetables in their specific zone. For all landscaping, irrigate with the most efficient system possible.

Fruitful trees to enjoy

Waterwise Tree Choices for Watersmart Landscaping

/in , /by

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.

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.

Water and Wastewater Scholarship Opportunities Available at National University

/in , /by

The new Waterworks Management Concentration in the Bachelor of Public Administration, offered by National University in partnership with Cuyamaca College, begins its second cohort of courses in August. Two new scholarship opportunities are now available to help prospective students overcome financial barriers and reach new career goals.

Developed in collaboration with regional employers, and driven by the rapidly growing demands for skilled career professionals in the water and wastewater industry, the Bachelor of Public Administration degree with a concentration in Waterworks Management, or BPA degree, allows graduates of the Cuyamaca College Center for Water Studies to transfer directly into National University bachelor’s program after earning their associate’s degree. Transfer scholarships are also available to graduates of other California community colleges.

Scholarship opportunities include:

  • The Opportunity Scholarship, which extends financial assistance to adult learned who are Pell Grant recipients
  • The Fast Track Scholarship, a merit-based award designed to help students complete their degree program by offering a free class for every three classes completed within six months, up to a 25% savings in tuition fees
  • The ADT Scholarship for CA CC Transfer Students

Dr. Joseph Allen, Director of Community College Pathways at National University, holds free live information webinars for prospective students every other Thursday. The next one is scheduled at 5 p.m. on May 20. Registration is free and open to anyone interested in the program. All courses in the program are taught online.

“While you are working from home, you now have digital access to a waterworks management education that can transform your career trajectory,” said Dr. Allen.

Demand for skilled professionals

Protect Your Hillsides and Slopes 

/in , /by

San Diego County features many native canyons, and many homes are located in proximity to a native canyon. Native canyon hillsides near your home should not be disturbed. The more you can adapt your home’s landscaping to Nature’s landscaping, the healthier and more low maintenance it will be.

Your home may have been built on canyon slopes leveled or filled. When planting in previously disturbed or built slopes and hillsides, choose low-water use plants and trees, especially deep-rooted native plant species. Climate-appropriate plants with strong root structures are the best choices. Their powerful root systems can help hold your soil together.

Coarse compost and mulch can be applied directly to hillside and slope surfaces, providing protection from the force of rainfall and shading exposed soils, if your slope is gentle with a 33% grade or less. With occasional and gentle irrigation, mulch will “knit” together.

Compost blankets are another type of erosion control mat applied to the soil surface to protect and preserve it. They can be used alone, with coir mats or other organic-engineered material with biodegradable grids for stabilization. Mats allow water to penetrate through to the underlying soils while retaining loose soil and debris, preventing erosion. You can plant right through them, or use pre-seeded products.

Irrigation tips to help preserve hillsides

Be sure your irrigation plan takes into account hills and slopes to prevent wasting water and erosion. Photo: Pixabay

Prepping Hillside for planting

When preparing a hillside for planting, plan your irrigation before doing any work. Low-volume rotating spray heads are ideal for sloped areas, if the space is large and the groundcover is uniform. Inline emitter drip tubing can also be effective, especially for wider-spaced shrubs and trees.

Water can be applied in repeated short periods over the course of 24 hours so it can be fully absorbed between application times. Runoff, erosion, and efficient deep watering should be factored into all landscaping plans, but especially for hillsides.

NOTE: When using a drip irrigation system, emitters should be placed above the plant basin. Spray systems should have check valves in all lower heads to avoid low point runoff. Irrigation for the top of the slope and bottom of the slope should be on separate valves.
