When to plant
Plant bare-root trees in early spring or fall. Many European plum varieties are self-fertile; Japanese plums need cross-pollinators. Trees bear in 3–5 years. Hardy in zones 3–9 (varies by variety). Annual pruning in late winter maintains an open canopy and removes dead wood.
Soil & site
Well-drained, fertile loam. pH 5.5–6.5. Work in compost before planting. Plums tolerate heavier soils than most stone fruits. Avoid low-lying frost pockets where late spring frosts can damage blossoms. Good air drainage is as important as soil drainage.
Feeding
Moderate feeder. Apply balanced fertilizer in early spring before bud break. Monitor shoot growth — aim for 10–18 inches of new growth per year. More than 18 inches indicates over-fertilizing; less than 8 inches indicates the tree needs more nutrition. Mulch with compost annually.
Common problems
Plum curculio (crescent-shaped scars on fruit — most serious pest in eastern North America). Brown rot (fuzzy brown rot on ripe fruit in wet weather — remove and destroy affected fruit). Black knot fungus (black tar-like swellings on branches — prune well below infection). Aphids. Japanese beetles.
When to harvest
Plums change color when ripe (depending on variety: red, purple, yellow, or blue-black). The flesh yields slightly to gentle thumb pressure near the stem end. A ripe plum separates from the tree with a gentle twist or comes away in your hand when lifted upward. The white bloom (waxy coating) is natural and should be present.
How to harvest
Cup the plum in your hand and give a gentle upward twist — ripe plums release easily. Don't squeeze tightly or you will bruise the fruit. Place (do not drop) into a padded container. Plums do not all ripen at once — check the tree every 2–3 days and harvest what is ready. Some varieties ripen over several weeks.
Storage & use
Fresh at room temperature: ripen for 1–3 days. Refrigerator: up to 2 weeks. Freeze: halve, pit, and freeze on a baking sheet then transfer to bags. Make jam or jelly (plums have natural pectin). Dry into prunes at 135–145 degrees F until shrivelled but not crisp. Can, pickle, or ferment for plum wine.
