Plum plum Plums are hardy, productive stone fruit trees suited to much of Sweden. European plum (Prunus domestica) dominates in home gardens with cultivars like 'Opal' and 'Victoria'; Japanese plum (P. salicina) needs warmer sites and reliable pollinators. Choose a sunny, sheltered position with good air movement to reduce spring frost damage and disease. Rootstocks determine tree size and hardiness: vigorous seedling or St. Julien A for larger, hardy trees; Pixy for smaller, earlier-bearing trees on sheltered sites. Most cultivars thrive in zones 1–4; the hardiest selections manage zone 5, and a few local varieties may stretch to mild parts of zone 6 in protected sites. Expect bloom in spring and harvest from August to late September depending on cultivar and site. Growing conditions LightFull sun (at least 6–8 hours of direct light daily). Soil typeDeep, well-drained loam enriched with organic matter; avoid waterlogging and high water tables. Water requirementModerate. Keep evenly moist during establishment and fruit swell; deep water in dry spells. Nutrient requirementModerate.
