Nissolia nyctitans Plant Care

Nissolia nyctitans (Machaerium nyctitans) belongs to the Fabaceae family within the Machaerium genus. Nissolia nyctitans is native to Brazil and Argentina.

Nissolia nyctitans displays a tall tree, spreading canopy growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Nissolia nyctitans produces small clusters of fragrant white or pink flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Nissolia nyctitans 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.

Nissolia nyctitans thrives in full sun to partial shade.

Machaerium nyctitans tolerates temperatures of 60–85°F. Nissolia nyctitans prefers humidity levels of 40–70%.

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

Feed Nissolia nyctitans 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.

Nissolia nyctitans 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.

Nissolia nyctitans can spread to about 20 ft (6.1 m) and reach about 30 ft (9 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 Nissolia nyctitans 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.

Nissolia nyctitans 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.

Nissolia nyctitans can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to machaerium chambersii plant care, which shares the same genus.

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

Nissolia nyctitans grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Nissolia nyctitans is native to Brazil and Argentina. In cooler regions, grow Nissolia nyctitans as a houseplant or bring it indoors before the first frost.
