Description Combination plum trees are built for growers who want more from less space. By grafting multiple compatible plum varieties onto a single root system, this tree delivers staggered harvests, built-in pollination support, and a broader flavor experience without the need for multiple plantings. Each 3-in-1 Combination Plum includes three varieties selected from a proven group of mostly Japanese plums, often one European-type variety included for contrast. The result is a guaranteed extended harvest window—an important advantage since Japanese plums are best enjoyed fresh and do not store for long. By spreading ripening across early, mid, and later-season varieties, this combination allows you to harvest at peak eating quality for well over a month rather than all at once, making the most of fresh, tree-ripened fruit. Regular pruning keeps the tree balanced and productive, allowing each grafted variety to contribute evenly. For home orchards, small yards, and growers who enjoy diversity, combination plums offer one of the most efficient ways to extend harvest season and flavor range. Overview Three plum varieties grafted onto one tree Designed for small spaces and efficient home orchards Extended harvest window through staggered ripening Semi-dwarf growth habit for easier pruning and care Cross-pollination between grafts improves fruit set Varieties Included Each tree will include three of the following varieties. Exact combinations vary by year and availability. Beauty — Early-ripening Japanese plum with sweet, juicy flesh and bright flavor. Burbank — Classic Japanese plum with mild sweetness and soft, juicy texture when fully ripe. French — Traditional European-type plum valued for dense flesh and processing quality. Italian — Renowned European prune plum; sweet, firm flesh excellent fresh or dried. Santa Rosa — Highly aromatic Japanese plum with sweet-tart flavor and tropical notes. Shiro — Yellow Japanese plum with honeyed sweetness and low acidity. Growing Details Latin Name: Prunus domestica / Prunus salicina (variety dependent)Site and Soil: 1/2 day to full day of sun; well-drained soilChill Requirement: Approx. 400–700 hours depending on varieties includedHardiness: USDA Zone 5–9Rootstock: Krymsk 1 (semi-dwarf)Bearing Age: 1–3 yearsSize at Maturity: Typically maintained at 10–14 ft tall and wide with pruningFlowering Time: Early to mid floweringRipening Time: Early through late seasonPollination: Self-fertile overall; cross-pollination between grafts improves yieldPests & Diseases: Standard plum considerations; good airflow and pruning are importantYield: highly productive once established; thinning recommended Additional Notes Grower’s Insight: Combination plums are ideal for growers who want variety without planting multiple trees. Managing balance between grafts is key—annual pruning keeps all varieties productive. Regional Insight: Performs well across temperate regions, including the Pacific Northwest, where mixed plum types benefit from moderate summers and extended harvest windows. Fruit size and ripening sequence may vary slightly by climate and heat accumulation. Thin fruit to prevent limb strain and improve overall quality. Explore more plums in our collection: Plum Trees
