Water Wise & Whimsy

by Soleil Tranquilli

After years of not quite getting around to designing my own landscape, I finally took the first steps toward a complete renovation in 2009. Eight years later, the renovated yard demonstrates our priorities: water conservation, use of predominantly native plants, reuse of materials, and support of wildlife, especially of pollinators. My home in Elk Grove, CA now showcases principles of ecological design serving as a demonstration garden. We have been featured twice on the sustainable landscape tour “Gardens Gone Native” tour, in the Northern Sacramento Valley of California, as well as my own local sustainable garden tour, Elk Grove Greener Gardens.

Laying the Groundwork

I began the project with sheet mulching in the spring of 2009. The mulch stayed in place for seven years, until the renovation began winter/spring 2015.

Before the renovation, the gardens were overrun with California poppies and Bermuda grass, and water ran from the roof and driveway during storms.

All that long term mulching created a very deep sponge-like soil filled with worms, even though we do have heavy clay to work with.

The new driveway includes permeable paving strips.

Recycled concrete (aka Urbanite) from the old driveway was saved for use in pathways, wall, and steps.

A new micro-patio behind a seat wall planter allows us to view wildlife visiting the raised plantings all year round.

Recycled windshield glass, also called Kryptonite, is incorporated into the wall and other areas for a sparkle of color.

 

 

Planting

Our planting theme was sages and other pollinator favorites, keeping to a low and cool palette. We used swaths of plants as much for visual impact as for pollinator delight. By paying attention to the structural details of the garden, we added color and textural interest that will hold the eye even when the garden is more spare in winter.

Special site considerations included a very persistent Bermuda lawn, heavy clay soils, feral cats, and a mostly shady northern exposure which receives extreme exposure from late afternoon western sun.

A suburban wind tunnel from east to west is managed with close plantings at edges of sidewalk to crowd out weed seed migrations, taller shrubs near the house and patio break wind flows.

Blue Fescue along the driveway will grow together to form a grassy weedblock.

Small trees and larger shrubs create multiple perches and cover for smaller birds, great for observing from the office windows.

Plantings begin to fill in garden beds.

Adding Lighting

An important aspect of the renovated garden is lighting. Although we are still awaiting professional low voltage landscape lighting, we know this will be the icing on the cake. In the meantime, we are field testing low cost solar options as found at Costco and other local sources. While costs are low, we also have found the look, product quality, and length of effect suffer greatly.

One of the low-cost lighting options we are testing.

We selected outdoor lighting that directs the light down, reducing light pollution.

We upgraded the outdoor light fixtures on the house with a lower profile modern design to accent our new landscape. The professional grade lighting is Dark Sky friendly, see darksky.org. Scientific evidence suggests that artificial light at night has negative and deadly effects on many creatures including amphibians, birds, mammals, insects, and plants that we want to invite into our landscape.

River Friendly Landscaping

My landscape design highlights our water management system that slows the water flowing from roofline to gutter. This landscape is located within the Laguna Creek Watershed; stormwater flows into Elk Grove Creek. Rainfall is checked and reabsorbed into the soil via several strategies: bioswales, rain garden, rain barrels, rain chain. In fact, this garden shows no runoff onto the sidewalk until storm events reach about 3″ of rainfall in 24 hours.

A sign in the yard proclaims its river-friendly landscaping.

Water from one roof line flows down a rain chain into the rain garden beyond.

The rain garden is hard at work during a storm. The clay soil allows no runoff, even with storm events of 3” rainfall.

Irrigation makes good use of Netafim grid with .4 emitters and a Water Sage smart controller.

California poppies and Blue Fescue fit the bill for low and very low water use.

A bonus tour of the back side yard reveals a Laundry to Landscape greywater system that we use to grow fruit trees and other moderate water use edibles, as installed by GrowWater.org. Shallow pits deposit water between edible plantings.

Water-wise Hydrozoning

All front yard plants are Water Use for Classification of Landscape Species (WUCOLS) indicating they are low and very low water use, with the exception of plants in pots, rain garden, and side yard edibles.

 

Walnut shells are a local agricultural byproduct that provides a clean, neat, long lasting mulch.

Professionally designed, installed, tweaked, and maintained by California EcoLandscapers, our garden is dedicated to gardening matriarchs Betty, Willa, Clara, and Martha.

Many thanks to all our collaborators and accomplices.
