Inga lacustris Plant Care

Inga lacustris (Inga lacustris) belongs to the Fabaceae family within the Inga genus. Inga lacustris is native to Veracruz state in eastern Mexico.

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

Leaf size: approximately 6 inches.

Water a young or newly planted Inga lacustris 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.

Inga lacustris thrives in full sun to partial shade.

Inga lacustris tolerates temperatures of 60–85°F. Inga lacustris 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 Inga lacustris to prevent waterlogging, which leads to root rot and fungal issues.

Feed Inga lacustris 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.

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.

Inga lacustris 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.

Inga lacustris 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 Inga lacustris 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.

Inga lacustris 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.

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

Inga lacustris 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.

Inga lacustris grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Inga lacustris is native to Veracruz state in eastern Mexico. In cooler regions, grow Inga lacustris as a houseplant or bring it indoors before the first frost.
