Leucaena magnifica Plant Care

Leucaena magnifica (Leucaena magnifica) belongs to the Fabaceae family within the Leucaena genus.

Leucaena magnifica displays a fast-growing small tree growth habit, reaching up to 20 ft tall with a spread of approximately 15 ft. Leucaena magnifica produces small white or pink flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Leucaena magnifica every 4–7 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.

Leucaena magnifica thrives in full sun to partial shade.

Leucaena magnifica tolerates temperatures of 60–90°F. Leucaena magnifica prefers humidity levels of 40–70%.

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

Feed Leucaena magnifica 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 good organic content. Avoid low spots where water collects after rain.

Leucaena magnifica 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.

Leucaena magnifica 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 Leucaena magnifica 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.

Leucaena magnifica 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.

Leucaena magnifica can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to red leadtree plant care, which shares the same genus.

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

Leucaena magnifica grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. In cooler regions, grow Leucaena magnifica as a houseplant or bring it indoors before the first frost.
