Robertson Navel Orange Trees for Sale
Citrus made easy for growers, nurseries, and distributors
The Robertson navel orange tree (Citrus sinensis ‘Robertson’) is a premium early-ripening navel variety ideal for home gardens and patios. Originating in Riverside, California, in 1925 as a natural limb sport of the Washington navel, Robertson navel trees are known for their smaller tree size and heavy production, making them a favorite for home gardeners seeking manageable trees with abundant, high-quality fruit.
Its fruit matures earlier than standard Washington Navel, often ready for harvest in December and January. The oranges are seedless, easy to peel, and exceptionally sweet, with a rich flavor and slight reddish-orange hue to the skin. The fruit often sets in tight clusters, which can result in slight flattening where it touches, but the quality remains excellent. Robertson navels hold well on the tree longer than many other early navels, giving homeowners more flexibility in harvest timing.

How Our Robertson Navel Orange Trees Are Different
Robertson navel orange trees from TreeSource stand out from those offered by many other nurseries because TreeSource is a specialized wholesale citrus grower that produces only certified, disease-free trees under strict USDA and CDFA protocols. All of our Robertson trees are propagated from true-to-type, virus-indexed budwood sourced through the California Citrus Clonal Protection Program (CCPP), ensuring genetic purity and long-term tree health.
TreeSource grafts Robertson navel onto carefully matched rootstocks selected for the customer’s region and growing conditions—whether for commercial nurseries, backyard orchards, or container growing. We offer rootstocks such as Carrizo, C-35, and Flying Dragon trifoliate, each influencing tree size, disease resistance, cold tolerance, and soil adaptability. Many retail nurseries sell only one generic rootstock option, but TreeSource can tailor the tree to the site’s needs.
Another difference is our professional-grade propagation and acclimation process. Trees are grown in greenhouses to protect against pests like Asian citrus psyllid and diseases such as HLB, then hardened off to ensure transplant success. TreeSource trees are also grown to a commercial standard of uniformity and vigor, so buyers receive trees that establish quickly and produce reliably.
In short, while other nurseries may sell Robertson navel oranges, TreeSource delivers a certified, professionally propagated, rootstock-customized, field-ready tree with a clean plant health record, making us a preferred source for serious citrus growers.
