Plum Tree

European plum (Prunus domestica) is a deciduous fruit tree with showy white flowers in spring and edible stone fruit. North Carolina State Extension describes a broad range of fruit colors and a mature height and width of about 10–20 feet, so individual cultivars can differ substantially. ## Site and Fruit Plant in full sun in fertile, moist soil with good drainage. The species profile lists USDA hardiness zones 4a–9b and notes that European plums bloom later than other plums, which can help in colder regions. Fruit is typically blue or black in the species profile, though named cultivars may have other colors. ## Maintenance Keep the root zone evenly moist during establishment and fruit growth, but avoid poor drainage. Prune to maintain a well-lit framework and remove damaged branches. Inspect foliage and fruit for common insect and disease problems; good air circulation and careful cleanup help maintain a productive tree. European plum cultivars vary in fruit color, size, flavor, and ripening season, so local cultivar choice can extend the harvest and suit fresh eating or cooking.
