  • Start With the Conversation That Determines Your Orchard’s Future

    Planting an almond orchard has never been a simple decision. But in today’s margin-tight environment, the choice of rootstock and variety combination is more than an agronomic preference — it is a 20- to 25-year business decision that can shape profitability, harvest efficiency, marketability and long-term risk.

    That was the focus of a grower-facing discussion moderated by Almond Board of California’s Michael Roots, with perspectives from Dave Phippen of Travaille and Phippen, Duarte Nursery’s John Arellano and grower Brandon Ribiero, at the 2026 Almond Crack Out event.

    For growers, the main message was clear. Do not make a planting decision in isolation. A new orchard should begin with a practical, sometimes uncomfortable, conversation about water, soil, rootstock, variety, harvest timing, market demand and, most importantly, economics.

    “Know Your Breakeven Cost Per Pound”

    Ribiero put the economics plainly when he said growers should “know your breakeven cost per pound.”

    That calculation should sit at the center of every planting conversation. Ribiero described it as a simple equation of cost divided by yield. If a grower expects production costs of $3,500 per acre and assumes 2,500 pounds per acre, the breakeven is about $1.40 per pound. If debt, land costs or other obligations push total costs to $4,500 per acre at the same yield, that breakeven rises to $1.80 per pound.

    That difference matters. In a market where prices can move quickly and margins can narrow, the wrong yield assumption, or the wrong rootstock and variety combination for a site, can make an orchard difficult to carry through the low points of the price cycle.

    Ribiero also warned that growers cannot always “save their way to prosperity.” Trimming some costs may help at the margins, but yield is often what moves the breakeven number in a meaningful way. That makes variety performance, rootstock fit and realistic production expectations central to the decision.

    Start With Water, Soil and Site Limitations

    Before selecting a variety, Ribiero said growers should first understand “all things water” — supply, quality and rights. Without water, he noted, the rest of the planting plan loses its foundation.

    From there, the conversation moves to soil. The right rootstock depends on what the site needs most, including vigor, anchorage, salt tolerance, disease resistance, replant tolerance or other characteristics. Prior Almond Board coverage of rootstock selection has emphasized the same point. Growers should identify a site’s limitations first, then select a rootstock that helps address the biggest risks.

    That means soil tests, water quality information, local grower experience and advisor input should all be part of the planning process. Once trees are planted, growers can adjust irrigation and fertility programs, but they cannot easily redo rootstock selection, variety choice or pre-plant soil preparation.

    Bring the Right People Into the Conversation Early

    Roots framed the panel around a gap that often appears in orchard planning. Growers may talk with a nursery early, but the handler is sometimes brought in after planting decisions are already made, or never at all. The panelists encouraged growers to widen the conversation before committing to trees.

    That group should include the nursery, handler, pest control adviser, neighboring growers and other trusted advisors who understand the region. Arellano said a nursery representative should be prepared to answer questions across rootstock, variety, fit for the site and how the planting will work operationally. If he does not have an answer, he said, the next step is finding someone who does.

    Ribiero said he often asks similar questions of different people one-on-one, looking for patterns in the answers. Where the advice is consistent, growers gain confidence. Where there are outliers, that is where the next question should be asked.

    Marketability Should Not Be an Afterthought

    Phippen brought the handler perspective into sharp focus. A variety may look attractive on paper, and a nursery may be able to supply the trees, but the buying public ultimately determines how that almond is valued. Market classification, quality expectations, defects, customer preferences and regional demand all matter.

    For Phippen, that means the marketing team should be part of the decision-making process. They can help growers understand what is moving well, what may be oversupplied and what buyers are asking for. A grower may be able to produce a variety, but the better question is whether the market wants it, and at what price.

    That conversation is especially important because handlers may serve different customers and markets. Quality tolerance, product form, timing and buyer preference can vary. A variety that fits one handler’s program may not be the right fit for another.

    Do Not Overcomplicate the Orchard

    One of Ribiero’s lessons from experience was the value of simplicity. He described a planting with multiple varieties intended to hedge risk around bloom, pollination and market movement. In practice, that complexity created harvest inefficiency without delivering a better return.

    His takeaway for growers was direct. Do not overthink it. A planting plan that is efficient, repeatable and well-matched to the site may provide more long-term value than one built around too many assumptions. Simplicity can reduce operational headaches and make it easier to scale what works.

    Pre-Plant Work Is the Last Chance to Get Some Things Right

    The panel also emphasized the importance of pre-plant groundwork and amendments. Ribiero noted that once an orchard is planted, it is difficult to incorporate materials into the active root zone. If a site needs amendments such as lime, gypsum, sulfur or compost, pre-plant is often the best opportunity to get them where they need to be.

    That point ties directly back to economics. A grower may be tempted to trim development costs up front, but those savings can become expensive if poor preparation limits tree performance for the life of the orchard.

    A Grower’s Pre-Planting Checklist

    • Calculate your breakeven cost per pound using realistic cost and yield assumptions.
    • Confirm water supply, water quality and water rights before moving deeper into planning.
    • Match rootstock to soil conditions, site limitations and long-term orchard goals.
    • Ask your handler how the variety fits current and future market needs.
    • Talk with neighboring growers who have experience with similar soils, water and varieties.
    • Include your PCA, nursery representative, handler and trusted advisors early.
    • Review independent field data and regional trial information where available.
    • Keep the orchard design practical for harvest timing, equipment and labor efficiency.
    • Complete needed soil preparation and amendments before planting.

    The Bottom Line

    Choosing an almond rootstock and variety combination is not just a horticultural decision. It is a business plan, a risk-management strategy and a long-term commitment to a specific site. The most successful planting decisions begin before the nursery order is placed, with honest conversations about what the orchard must produce, what the market will reward and what the grower can afford.

    For growers considering a new planting, Ribiero’s advice is a practical place to start. Know your breakeven cost per pound. From there, every other decision — water, soil, rootstock, variety, marketability and orchard design — should help answer one question.

  • ‘Demo 57 Orchard’ Near Los Banos Showcases 57 Almond Variety and Rootstock Combinations

    A new almond demonstration orchard featuring 57 combinations of varieties and rootstocks has been planted near Los Banos to help growers evaluate planting decisions for the next generation of orchards.

    Known as “Demo 57,” the RPAC Variety & Rootstock Demo Orchard was planted this year adjacent to the RPAC and PAPC facilities, allowing visiting growers to easily walk through the orchard and observe how different combinations perform over time.

    The project was designed so growers can evaluate today’s commercial varieties from prominent tree nurseries alongside newer selections and rootstocks that may shape future almond plantings.

    The orchard was planted in the same year PAPC founder and longtime grower Louie Parreira will celebrate his 100th birthday, a milestone that highlights how much almond production has evolved over the past several generations.  Louie’s son, David Parreira, reflected on how orchards were planted when earlier generations of the family first entered the almond business.

    “When my father and grandfather planted their first almonds, they were on a 24-foot square spacing, about 75 trees per acre. They planted four rows of Nonpareil, then two rows of Mission, then four rows of Nonpareil and two rows of Davey and so on. I don’t think they put much fertilizer on and irrigated only when the trees looked stressed. They were happy to make 500 pounds per acre. Harvest was all by hand and the beekeepers paid the grower to bring bees in so they could make honey. Obviously, almond production has changed a lot!”

    Almond grower and RPAC partner Dennis Soares, who entered the almond industry after two decades in the cotton business, said the industry has changed dramatically since he planted his first orchards.

    “Almond prices were around 75 cents a pound when I planted my first almonds in 1999. Coming from the cotton business, we learned some lessons the hard way about planting the wrong varieties, rootstocks and spacings, like planting Wood Colony at 18-foot spacing.

    “Today plentiful information is available to growers, and making the right decisions is critical when planting a new orchard.  This demo orchard gives growers a chance to see many different combinations and evaluate what might work best for their operation.”

    Soares noted the project also benefits from agronomic support from David Doll, widely known in the industry as the Almond Doctor.

    “Working with David Doll on agronomic support has been invaluable. He provides a tremendous amount of information and stays closely connected with the almond growing community around the world.”

    The project was developed in collaboration with leading nursery partners supplying genetics and planting material.

    John Duarte, President of Duarte Nursery, expressed that “we appreciate RPAC providing nurseries this opportunity to put forward our newest ideas and genetics. For our planting, we included Yorizane high-topped containerized trees on Bright’s Hybrid 5. We believe that this new orchard system will be the highest production and most efficient almond orchard to date. Time will tell. Growers will see it firsthand.”

    “Rootstock selection plays a major role in long-term orchard performance,” said Seana Day, CEO of Dave Wilson Nursery. “Having a demonstration site like this allows growers to compare combinations and better understand how they may perform in commercial plantings. We appreciate RPAC bringing together multiple nursery partners to make this possible.”

    “New almond varieties and rootstocks are coming to market faster than ever, and growers need reliable ways to evaluate them,” said Tom Burchell, owner of Burchell Nursery. “This orchard gives the industry a place to see how different combinations perform side by side in the same environment. We are proud to partner with RPAC on a project that will provide valuable insight for growers across California.”

    In addition to the variety and rootstock trials, the orchard includes a hedgerow planted with ten species of California native plants designed to demonstrate how habitat plantings may support beneficial insects in almond orchards.

    The Demo 57 Orchard is expected to serve as a site for future grower visits and field discussions as the different combinations develop. — Story by RPAC LLC

  • Variety and Neighboring Crops are Predictors of Leaffooted Bug Risk in Almond

    Leaffooted bug is a sporadic pest in almond, but damage can be significant in years when pest pressure is high. The pest may evade early detection by growers and PCAs because it overwinters as adults in vegetation outside of the orchard and tends to colonize the upper tree canopy, rendering it generally out of sight. As a result, pest pressure is often realized after damage has occurred. The damage may vary considerably between almond varieties, adding yet another challenge for diagnosis.

    In Tulare County, heavy leaffooted bug damage was observed in May 2025 in almond orchards surrounded by citrus.  Adult leaffooted bugs (Figure 1A) overwintered in the citrus and then entered the neighboring almond orchards in March and April. By early May, symptoms of infestation included extensive nut drop (Figure 2A) and gummosis on the nuts (Figure 2B). Although the adults were not observed in the orchard, the pest was identified based on the observation of the characteristic egg strands of leaffooted bug (Figure 1B). In orchards with Nonpariel and Aldrich, both varieties were affected; however, the nut drop was more extensive in Aldrich than Nonpareil (Figure 2A).

    The full impact of the pest may not be realized until harvest because the quality of affected nuts remaining on the tree may also be compromised, thus reducing crop value. Nuts that are stung in late April to early July can be severely shriveled, have sunken lesions, or a brown spot depending on how developed the kernel was prior to feeding (Fig. 3, row 2-5).  These nuts stay in the tree, are harvested, and can significantly increase the percentage of nuts classified as inedible during nut quality assessments.  When examining a library sample of damaged kernels at harvest, nuts damaged by leaffooted bug fall into the same category as stink bug damage, as kernels damaged by these two pests are indistinguishable.

    In 2007, UCCE Kern County Farm Advisors David Haviland and Mario Viveros had the opportunity to evaluate the relative susceptibility of 15 almond varieties to leaffooted bug damage. That year, leaffooted bug invaded a Kern County variety trial research block that included 15 varieties planted in replicated, randomized blocks. This unique situation allowed for unbiased evaluation of the performance of varieties under equivalent pest pressure. Results indicated that the average number of aborted nuts per tree ranged from 0 to 33% of the total crop. Additionally, at harvest, the estimated rejects from leaffooted bug damage ranged from 0 to 30% of the harvested yield. Researchers also noted that crop loss varied by variety, with Fritz exhibiting the highest crop loss at 63%, followed by Sonora, Aldrich, Livingston, Monterey and Carmel.  The other varieties in the block had 3% or less total damage from the pest.

    The underlying basis for the differential susceptibility of almond varieties to leaffooted bug is unknown. Damage does not appear to be related to harvest date or shell hardness at harvest. Other factors such as plant volatiles, hull thickness, or shell hardness in April and May when the bugs are present may play a role in varietal susceptibility. Haviland and Viveros also noted that varietal susceptibility is somewhat relative, explaining that Wood Colony exhibited low susceptibility to leaffooted bug in the research plot, but significant damage was reported on Wood Colony in commercial orchards when combined with less susceptible varieties (ie. Nonpariel and Carmel).  These observations indicate that leaffooted bug prefers certain varieties, but in the absence of a preferred variety, the pest will remain in the orchard and feed on the most preferable variety of the less-preferred varieties present in the orchard.

    The 2025 observations in Tulare County, taken in consideration with the 2007 data from the UCCE variety trial suggest that the best way to monitor leaffooted bug is to focus attention on the most susceptible variety in the field. Gummosis and nut drop in the most susceptible variety will serve as an indicator of pest pressure in a given orchard. Growers with Fritz, Sonora, Aldrich, and Livingston should be extra vigilant in monitoring pest pressure.  Haviland and Viveros note that orchards composed of relatively unsusceptible varieties will have characteristically lower risk of leaffooted bug damage. Additionally, growers and PCAs should consider pest pressure from surrounding orchards and landscape plants that may serve as overwintering sites for the adults, thus contributing to the cryptic nature of the pest.

    Management programs for leaffooted bug consist of monitoring for the pest and spraying primarily with pyrethroids, when needed. Pest management guidelines for leaffooted bug and other pests can be found at www.ipm.ucanr.edu and reports of Almond Board of California-sponsored research can be found at https://www.almonds.com/research-database. — By Elizabeth Fichtner, UCCE Farm Advisor, Tulare County, and David Haviland, UCCE Entomology Advisor, Kern County
