Duarte Nursery

What Duarte Nursery does

Duarte Nursery, Inc. is a family-owned permanent crops nursery headquartered in Hughson, California, self-described as the largest in the United States. Founded in 1988 and now in its third generation of family ownership under brothers John and Jeff Duarte, the company produces containerized fruit and nut trees, clonal rootstocks, and winegrape vines for commercial growers across the West Coast. Core product lines include almond varieties (with the USDA-released Yorizane self-fertile almond as a flagship), VigorClone clonal pistachio rootstocks, clonal walnut rootstocks, and the UberVine winegrape vine system (which is being discontinued after 2025).

The company's underlying technology is built around a state-of-the-art tissue culture laboratory (Dry Creek Laboratory) that produces millions of micropropagated starts annually, enabling clonal reproduction of superior plant genetics, virus elimination, and in-vitro selection for salt and drought stress tolerance. This laboratory capability underpins a 100% containerized production system designed to minimize soil-borne pathogen exposure and enable year-round delivery. Duarte holds multiple US Plant Patents covering proprietary clonal rootstocks and varieties, and validates performance through third-party UCCE Regional Variety Trials.

Duarte generates revenue through direct one-time sales of nursery stock to commercial permanent crop growers, distributed via a six-representative field sales team covering California's major growing regions, a toll-free phone line, and an inside sales email channel. The company also markets through annual industry events including Friends Day (1,000+ guests) and Yorizane Field Days. Customer relationships span individual commercial almond, pistachio, walnut, and winegrape growers as well as enterprise accounts including Blue Diamond Growers. Pricing is quote-based and not publicly disclosed, with strategic partnerships with the Almond Board of California, UCCE, and the GEM Alliance reinforcing industry positioning.
