Bush Plum Plant Care

Bush Plum (Prunus dumosa) belongs to the Rosaceae family within the Prunus genus. Bush Plum is native to North America.

Bush Plum displays an upright, spreading tree growth habit, reaching up to 20 ft tall with a spread of approximately 15 ft. Bush Plum produces showy clusters of white or pink blossoms.

Leaf size: approximately 4 inches.

Water a young or newly planted Bush Plum every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Bush Plum thrives in full sun to partial shade.

Prunus dumosa tolerates temperatures of 50–90°F. Bush Plum prefers humidity levels of 40–70%.

Well-draining loamy soil with good organic content. Good drainage is essential for Bush Plum to prevent waterlogging, which leads to root rot and fungal issues.

Feed Bush Plum every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with full sun to partial shade and well-draining loamy soil with good organic content. Avoid low spots where water collects after rain.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Bush Plum can spread to about 15 ft (4.6 m) and reach about 20 ft (6 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Bush Plum while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.

Bush Plum can be propagated through softwood cuttings, hardwood cuttings, grafting. Similar propagation techniques also apply to apricot tree plant care, which shares the same genus.

Bush Plum is susceptible to aphids, scale insects, caterpillars. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.
