Newtonia erlangeri Plant Care

Newtonia erlangeri (Newtonia erlangeri) belongs to the Fabaceae family within the Newtonia genus. Newtonia erlangeri is native to Kenya, Somalia, and Tanzania.

Newtonia erlangeri displays a tall, upright tree growth habit, reaching up to 15 ft tall with a spread of approximately 8 ft. Newtonia erlangeri produces small clusters of white or pink flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Newtonia erlangeri 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.

Newtonia erlangeri thrives in full sun to partial shade.

Newtonia erlangeri tolerates temperatures of 60–85°F. Newtonia erlangeri prefers humidity levels of 40–70%.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Newtonia erlangeri to prevent waterlogging, which leads to root rot and fungal issues.

Feed Newtonia erlangeri 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun to partial shade and well-draining loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Newtonia erlangeri is suited to USDA Zone 13a.

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.

Newtonia erlangeri can spread to about 8 ft (2.4 m) and reach about 15 ft (5 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Newtonia erlangeri 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.

Newtonia erlangeri is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Newtonia erlangeri can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to nan plant care, which shares the same genus.

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

Newtonia erlangeri grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Newtonia erlangeri is native to Kenya, Somalia, and Tanzania. In cooler regions, grow Newtonia erlangeri as a houseplant or bring it indoors before the first frost.
