Fastigate Inga Plant Care

Fastigate Inga (Inga fastuosa) belongs to the Fabaceae family within the Inga genus. Fastigate Inga is native to Brazil, the Caribbean, and Venezuela. Fastigate Inga is also known as Inga fastuosa.

Fastigate Inga displays a tall, spreading tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Fastigate Inga produces small, fragrant white flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Fastigate Inga 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.

Fastigate Inga thrives in full sun to partial shade.

Inga fastuosa tolerates temperatures of 60–85°F. Fastigate Inga prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added organic matter. Good drainage is essential for Fastigate Inga to prevent waterlogging, which leads to root rot and fungal issues.

Feed Fastigate Inga 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 organic matter. Avoid low spots where water collects after rain.

Fastigate Inga is suited to USDA Zone 10a – 12b.

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.

Fastigate Inga 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 Fastigate Inga 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.

Fastigate Inga 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.

Fastigate Inga can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to white inga plant care, which shares the same genus.

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

Fastigate Inga grows outdoors in USDA Zone 10a – 12b. It survives winters down to planting zone 10a. Fastigate Inga is native to Brazil, the Caribbean, and Venezuela. In cooler regions, grow Fastigate Inga as a houseplant or bring it indoors before the first frost.
