Give oaks water once a month

Even though California's majestic oak trees are generally considered drought tolerant, the last four years of well-below-average rainfall are taking a toll, reported the Sierra Sun Times.

"In some parts of the state, oaks are being deprived of water for as long as nine months, creating extreme water stress," said Greg Giusti, a forest and wildlands advisor for UC Agriculture and Natural Resources. Giusti is headquartered in the UC ANR Cooperative Extension office in Mendocino County. 

Giusti and Kris Randal, the UC Master Gardener coordinator for Mariposa County, suggest that California residents with oaks on their property give the trees a good soaking once a month during the summer.

The water should be applied around the drip line - the area below the outstretched branches - but not near the trunk. A permeable soaker hose is an ideal tool for slow application over the wide area. Allow the water to run until it has soaked down to a depth of 12 to 18 inches, which can be detected with a long probe such as a screwdriver. "If it comes up with signs of moisture at the tip, you're good," the article says.

Randal said it is important to let the soil dry out completely between waterings, because oaks are susceptible to root fungus that can grow in warm, damp soil.

Even if water is unavailable and the leaves begin to turn brown or fall, the experts suggest waiting for spring before considering removing the tree.

"If you tree leafs out, it's still alive," Randall said. "And in this drought, give it extra time to leaf out."

Take a short jaunt in Mariposa to see a treasure of California native plants

A path along Mariposa Creek where UC ANR Master Gardeners have planted native species.
A half-block from the highway that brings thousands of tourists to Yosemite National Park each year, the UC Agriculture and Natural Resources (UC ANR) Master Gardeners landscaped a short and scenic hiking path that provides the perfect break on a long drive.

The quarter-mile-long Mariposa Creek Parkway runs parallel to State Route 140 (Main Street in downtown Mariposa) on Stroming Road between Eighth and Sixth streets. Along the path, the Master Gardeners created the California Native Plant Demonstration Garden, which includes dozens of beautiful, drought-tolerant plants labeled for easy identification.

The path, which follows a short stretch of Mariposa Creek, was designed to increase appreciation for native flora and encourage Californians to consider “going native” in their own landscapes, said Kris Randal, coordinator of the Master Gardener program for UC ANR Cooperative Extension in Mariposa and Merced counties. Water shortages associated with the ongoing California drought are also driving interest in landscaping with native plants.

“Many natives are drought-tolerant, adapted to local soils, and rarely need fertilizers or pesticide treatments,” Randal said. “With some care and irrigation to get them started, they create a beautiful natural setting that brings pollinators and wildlife into your backyard.”

Randal was an advocate for native plants even before joining UC ANR. As a community educator for the Resource Conservation District in Mariposa County, she coordinated the transformation of a weedy parking lot around the district's building on the Mariposa Fairgrounds into a beautiful display of plants and wildflowers that occur naturally in the surroundings.

She did the same thing in her own Mariposa yard, bringing in and nursing the plants that flourish in natural areas.

“After I planted native brush and wildflowers, it was a joy for me to watch diversity come into my yard. Plant it, and they will come,” Randal said.

Randal suggests growing California native plants, even over native plants from other parts of the world with Mediterranean climates – such as Australia, Chile and South Africa – which also are often recommended because of their low water needs.

The California natives, she said, support local wildlife and pollinators, have historical and cultural importance, and save time and expense while adding beauty and ecological health to the environment. Native plants attract native bees, butterflies and hummingbirds and provide seeds, nuts and fruits for other native birds and wildlife. Native plants promote soil health by supporting flora and fauna that flourish underground.

“There's all kinds of magic going on under the soil,” Randal said.

As a first step toward converting to native landscaping, Randal suggests finding a natural area close to home and visiting it every few weeks to see what is growing, and what is blooming. Take notes and consult a plant guide or the Internet to identify the plants.

“It sounds like a lot of work, but it's not,” Randal said. “It's fun.”

This task is particularly convenient for Mariposa County residents, where the UC ANR Master Gardeners planted a wide array of beautiful native plants in one place.

Under the auspices of UC ANR Cooperative Extension, Master Gardeners are trained by UC ANR academics in research-based and sustainable gardening and landscaping practices. They become volunteer educators for non-commercial gardeners. In Mariposa County, a significant amount of volunteer time goes into tending the native plant garden.

In early spring, one of the first deciduous shrubs to leaf-out on the pathway is California buckeye. The leathery, pear-shaped fruits contain seeds that are easily sprouted, or they can be used in dried flower arrangements.

Along the trail, visitors will find California fuchsia, known by many as a natural hummingbird feeder. Blue elderberry, columbine and manzanita also attract hummingbirds to the demonstration garden.

Randal points out soap root, which looks like a grouping of long spindly leaves growing from the ground. Native Americans used pulp from the bulb to make a soapy lather, and they used the fibrous and hairy husks of the bulb to make small brushes to whisk out acorn shell debris from grinding holes.

One of Randal's favorite natives, she said, is a low creeping sage. The fragrant plant forms a low mat as big as 10 feet across with blue-violet flowers May to June. “This is great in a pine forest where it will get afternoon shade,” Randal said.

A lovely shrub known as Ceanothus blue jeans produces profuse powder-blue clustered flowers. The tall evergreen provides a colorful show of flowers with no care or irrigation. Western redbud explodes with magenta blossoms in the spring. Native Americans used the branches for basket weaving and made a red dye from the bark. Red Twig dogwood produces beautiful white blooms in early summer, and its bright red branches are a unique display in the winter.

“Growing native plants help you appreciate your surroundings and feel more connected to the natural world,” Randal said. “It attracts more life and that's why many of us garden.”
