False rusty plum Plant Care

False rusty plum (Prumnopitys ferruginoides) belongs to the Podocarpaceae family within the Prumnopitys genus. False rusty plum is native to New Caledonia. False rusty plum is also known as False rusty pine.

False rusty plum displays a tall, conical tree growth habit, reaching up to 50 ft tall with a spread of approximately 20 ft. False rusty plum produces small, inconspicuous flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted False rusty 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.

False rusty plum thrives in partial to full shade. The optimal light range is 100–500 lux. Avoid placing False rusty plum in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Prumnopitys ferruginoides tolerates temperatures of 50–75°F. False rusty plum prefers humidity levels of 40–70%.

Well-draining, acidic soil with high organic content. Good drainage is essential for False rusty plum to prevent waterlogging, which leads to root rot and fungal issues.

Feed False rusty plum every 8 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 partial to full shade and well-draining, acidic soil with high organic content. Avoid low spots where water collects after rain.

False rusty plum is suited to USDA Zone 10a – 11b.

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.

False rusty plum can spread to about 20 ft (6.1 m) and reach about 50 ft (15 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune False rusty 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.

False rusty plum is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

False rusty plum can be propagated through seeds, semi-hardwood cuttings.

False rusty plum is susceptible to spider mites, scale insects. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.
