UC Small Farm Advisor works with grower to push the "Horticultural Envelope"

This article by Matt Kettman was published in the Santa Barbara Independent on October 6, 2015.  UC Small Farm Advisor, Mark Gaskell, has been providing technical assistance to small-scale growers in Santa Barbara and San Luis Obispo counties for more than 20 years.  Sandra Newman has established certified organic blueberries, gooseberries, mulberries, and other specialty crops on her 100 acres of sandy soil and been growing and marketing them successfully for more than a dozen years.

Blueberries, Pinot Noir, Mulberries, and More Thrive at Sandra Newman's Forbidden Fruit Farms Near Lompoc

Story by Matt Kettmann

FRINGE FARMER: Pushing the boundaries of what can grow just 12 miles from the ocean, Sandra Newman is growing wine grapes, blueberries, gooseberries, mulberries, hardy kiwis, and more.
Soon after Sandra Newman purchased 100 acres of sandy hills just east of Lompoc in 2002, she visited a small farms expert in Santa Maria to inquire about planting wine grapes. The property touched the western border of the renowned Sta. Rita Hills wine-growing appellation, many of her neighbors had grapes, and, as a dedicated horticulturalist who studied plant science decades ago at the University of Delaware, Newman figured finicky pinot noir would be a worthy challenge to grow just 12 miles from the ocean.

The advisor, however, asked whether she had money and time to burn. As a widow approaching retirement age, lacking a fortune, and still paying bills through her Orange County–based digital SEC filing service, Newman had neither luxury. “I have a budget,” Newman told me during a visit this past summer to the property. “My daddy didn't buy it for me; my husband didn't buy it for me. I'm probably the only one out here who still has a mortgage.”

So the advisor suggested planting blueberries, which, if they ripened anytime other than when the blueberry market is typically flooded, would deliver nearly instant returns. In went two acres of the shrubs — they ripened exactly at the right times — and Forbidden Fruit Orchards was born. Newman was soon selling her organically grown blueberries to upscale grocers and through farmers' markets from San Francisco to Los Angeles, using the proceeds to grow her property from a few abandoned apple trees into a dynamic estate with multiple buildings.

And she kept planting, from more blueberries (now 8.5 acres) to Pakistani mulberries, avocados, apples, red and pink currants, figs, bananas, gooseberries, and more. Among the more interesting choices are the hardy kiwis (smaller than usual and hairless so that you eat the whole thing, but she's still getting them to flower at the right time), green tea (an experimental project in conjunction with the University of California), and hops for beer, which are tended to by Brian DeBolt and Casey Birthisel of Pacific Valley Hops. Many of these items will be integrated into the menu of the upcoming farm-to-table, four-course dinner at the property on November 7, when Chef Sally Ruhl will unveil many of the ingredients she's posting to Twitter under her handle @SallyRuhl.

With the blueberry cash flow, Newman finally did plant wine grapes in 2007, today amounting to 7.5 combined acres of pinot noir and chardonnay. Some grapes are sold to other vintners, but she makes about 600 or so cases in her souped-up garage under the brand Cebada, named after the canyon. The wines are very light and elegant in a deliberately Old World style; the chard is tight and racy, the pinot requires a bit of bottle age to truly shine (so 2011 is great now), and the 2014 rosé is one of the best pinks I've tried of the vintage. Plenty of others think so, too, as it's rare for me to hear so many wine lovers I know rave about the same brand without any prompting.

You can taste them with an appointment at the farm, or just head to Isabella Gourmet Foods on Figueroa Street in downtown Santa Barbara, where Cebada wines are poured upstairs and Newman's jams, teas, and other products are also sold. To get the most bang out of your $10, try them during Thursday and Friday's Classy Hour, when sips come with small food pairings from 4-6 p.m.

Newman also makes a blueberry wine, further evidence that those tiny berries remain the core strength of Forbidden Fruit Orchards. She's currently tending to bidding wars over the recent harvest, since her bushes reach their prime when the market is most desperate. “We hit a really nice window,” she said, “because Chile is not in and the northern hemisphere is done.”

It's certainly not a stress-free existence, and with so many fruits in the air, Newman admits that “sometimes you just have crazy days.” But she's happy with her 100 acres of sand and the evolving cornucopia of trees, vines, and shrubs. “I just love farming,” said Newman. “I love being able to grow and pick the fruit. It's just a passion.”

No Blues for California Blueberries

Summer is upon us, and nothing quite says summer more than eating freshly picked blueberries or using them in delicious desserts. California blueberry growers can find an additional treat – the newly published UC IPM Pest Management Guidelines for blueberry on the UC IPM web site. California is quickly becoming a top producer of blueberries, and the new guidelines can help with management information on blueberry pests such as thrips, light brown apple moth, and spotted wing drosophila with additional information on pesticides and resistance.

It may be hard to believe but as of 1996, blueberry production was limited to colder states like Washington, Michigan, New Jersey, and Oregon, where naturally acidic soils and winter climates suit the traditional highbush varieties. As recently as 1997, California blueberries were only growing on less than 200 acres across the state. According to the latest CDFA statistics, 2012 continued to show what has been an increasing trend for California blueberries, with more than 40 million pounds harvested, $133 million sold, and plantings in more than 4,700 acres spanning San Joaquin, Tulare, Kern, Ventura, and Fresno counties.

In 1995 the University of California Small Farms Program and cooperating farmers started evaluating low-chill southern highbush varieties in San Luis Obispo and Ventura counties. They found that “low-chill” southern highbush varieties offered the most promise for extended season production on the central coast. By 1997, Kearney Agricultural Center trials found that southern highbush cultivars were also well adapted to the semiarid climate of the San Joaquin Valley. Further evaluations identified the best yielding and flavorful cultivars. Initial and ongoing UC Small Farms studies have escalated California blueberry production swiftly up the learning curve, providing California farmers of small to moderate operations a niche in a very competitive market.

Today, California blueberries are harvested from May through July in the San Joaquin Valley and January through May on the central coast. While consumer demands are on the rise and profits can be excellent, producing and harvesting blueberries in California is expensive. It can run over $10,000 per acre to prepare a field because successful cultivation in many areas necessitates soil and irrigation water acidification and adding tons of mulch per acre. Specialized equipment, labor-intensive pruning, and pests like light brown apple moth, thrips, and spotted wing drosophila can add substantially to cost. Therefore, getting the right information and planning is imperative. While the UC Small Farms Program continues to develop field and market research for blueberry production in California, growers can also turn to the newly published Pest Management Guidelines for blueberries.

Can less water grow better berries?

It might be pouring rain today, but soon enough California will be dry again. As demand for water for a growing urban population and for environmental restoration increases, farmers throughout the state are working to grow crops using as little water as possible, and UC is working with them.

"Water supplies are being constrained. Farmers are facing reduced access to water," said Shermain Hardesty, a UC Cooperative Extension specialist in the Department of Agricultural and Resource Economics at UC Davis.

A team of researchers, led by Hardesty, is in the middle of a three-year investigation into the effects of different irrigation levels on the quality, shelf-life, nutritional content, sensory quality and yield of some delicious annual and perennial crops. They're trying to learn if some of our favorite treats - strawberries, blueberries and blackberries - can be even more tasty if they're grown with less water than usual.

The research involves using some elaborate formulas for determining how much water is needed. UCCE advisor Richard Molinar, working with small farms in Fresno County, is irrigating small plots of strawberries with different amounts of water, some at 125 percent of the normal rate, some at 100 percent, and others at 75 percent and 50 percent of normal. In San Diego County, UCCE advisor Ramiro Lobo is doing similar research on strawberries and blueberries; UCCE advisor Manuel Jimenez is working with blackberries and blueberries in Tulare County; UCCE advisor Aziz Baameur is planting strawberries and blackberries in Santa Clara County, and UCCE advisor Mark Gaskell is studying blackberries in Santa Barbara County.

Once the berries are grown, they need to be tested - and testing means tasting in this project. The research team is holding tasting sessions to let the public judge which berries they prefer. If you've ever tasted a dry-farmed tomato, you might guess the answer. The first tasting session was held at the Davis Farmers' Market in June, with seven more coming soon at farmers' markets and grocery stores around the state.

Taste is a great quality to measure, but only one aspect of the study. Berries are already known for having a high nutrient content, but growing them with less water might give them even higher nutritional value. The team expects to find nutrition density to be highest at the lowest irrigation levels. To test this concept, UCCE specialists Elizabeth Mitcham and Marita Cantwell, experts in postharvest science affiliated with the Department of Plant Sciences at UC Davis, are doing nutritional quality analysis of the berries as they are picked.

Because they have to deal with so many variables, from weather to pests to unexpected competition and volatile prices, farmers are often called gamblers. Because of all these uncertainties, farmers are likely to try to control what they can. Research team member Lawrence Schwankl, a UCCE specialist in the Department of Land, Air and Water Resources at UC Davis, says that many farmers are currently over-watering many crops.

"Over-irrigation is cheap insurance, especially for such high value crops," he said.

He explained that more water tends to grow bigger berries. Since the harvest is not mechanized for berry crops, it takes as much effort to pick a small berry as a large berry, making more efficient use of the pickers' time and filling the basket more quickly if the berries are bigger.

Such a trade-off for the farmers! The public may decide that they prefer smaller berries with more taste, and the scientists may decide that smaller berries are more nutritious, but will it be profitable to grow better berries? It may depend on how much smaller, and on how much less water for how much better nutrition and taste. It may depend on the water rates, says Hardesty. She will be taking all of these variables into account to determine the potential impact on profitability of lower irrigation rates on berries.

The team, which also includes UCCE advisors Michael Cahn in Monterey County and David Shaw in San Diego, will report the results of their study to California farmers in the final year of the project. This project is funded by a California Department of Food and Agriculture Specialty Crop Block Grant.

Western Farm Press runs 1,000-word story on Kearney blueberry event

The annual Blueberry Open House at the UC Kearney Agricultural Research and Extension Center last month warranted lengthy coverage by Western Farm Press.

Freelance writer Dennis Pollock reported that Manuel Jimenez, UC Cooperative Extension advisor in Tulare County, a small-scale farming expert, walked among the mature blueberry plants at Kearney, describing their good points and bad points.

"The perfect blueberry would be one that is big, firm, sweet, easy to harvest and grows in high pH (soil conditions)," he said.

At the event, Richard Molinar, UCCE advisor in Fresno County, small-scale farming, conducted a blueberry tasting, allowing those who attended to vote for their favorite three varieties. He said that variety isn't the only factor impacting flavor.

"Flavor is also affected by weather, soil factors, plant nutrition and irrigation frequency," Molinar said.

Jimenez introduced growers to two new research projects in blueberries:

  • Jimenez and Larry Schwankl, Kearney-based UCCE irrigation specialist in the UC Davis Department of Land, Air and Water Resources, have teamed to study the effects of varying irrigation levels on blueberries.

  • Jimenez has grafted popular blueberry varieties onto the roots of farkleberry (Viccinium abroreum), which has greater tolerance of alkaline soils like those found in the San Joaquin Valley. By reducing or eliminating soil and water acidification, using the alternate rootstock may provide a significant cut in production costs.

UC aims to improve economic viability of California blueberry farms

The farkleberry is related to blueberry, but more tolerant of alkaline soil.
California consumers have grown accustomed to enjoying locally grown blueberries in the last decade. Much of the credit goes to UC Cooperative Extension advisor Manuel Jimenez of Tulare County, who has been studying blueberry production and varieties at the UC Kearney Agricultural Research and Extension Center since 1998.

California’s abundant sunshine enables growers to produce high-quality, very sweet Southern Highbush variety blueberries. But, blueberry plants are difficult and expensive to establish and maintain, in part because of California's soil chemistry.

“Blueberries are adapted to grow in forests, in acidic soils,” Jimenez said. “We’re growing them in a desert in alkaline soil. That requires that we acidify the soil when we establish the crop and continuously acidify the irrigation water – which is very costly.”

For example, a 2009 Blueberry Cost Study produced by UC Davis calculated that equipment needs for acidification - including a storage tank, pump and monitoring kit - amounts to $5,500. In addition, the growers must purchase large quantities of sulfuric acid to add to the soil and irrigation water.

Reducing acidification cost is the goal of a new blueberry trial at Kearney, in which Jimenez has grafted the most common commercial blueberry varieties on the roots of farkleberry plants (Vaccinium arboreum). Farkelberry is a small, stiff-branched evergreen bush that is more tolerant of alkaline soils than blueberries.

So far, the two-month-old plants seem to be growing well in their naturally alkaline soil. The coming years will reveal whether using this technique will improve the economic viability of California blueberry farms and provide California consumers with local, healthful and delicious blueberries at a reasonable cost.

The project is being conducted in collaboration with Oregon State University and Florida State University.
