Trigynaea triplinervis Plant Care

Trigynaea triplinervis (Trigynaea triplinervis) belongs to the Annonaceae family within the Trigynaea genus. Trigynaea triplinervis is native to Ecuador.

Trigynaea triplinervis displays a small tree, spreading canopy growth habit, reaching up to 15 ft tall with a spread of approximately 10 ft. Trigynaea triplinervis produces small, fragrant yellow flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Trigynaea triplinervis 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.

Trigynaea triplinervis thrives in partial shade to full sun.

Trigynaea triplinervis tolerates temperatures of 60–85°F. Trigynaea triplinervis 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 like compost or leaf mold. Good drainage is essential for Trigynaea triplinervis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Trigynaea triplinervis 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 partial shade to full sun and well-draining loamy soil with added organic matter like compost or leaf mold. Avoid low spots where water collects after rain.

Trigynaea triplinervis 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.

Trigynaea triplinervis can spread to about 10 ft (3 m) and reach about 15 ft (5 m) tall. Space plants about 10 ft (3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Trigynaea triplinervis 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.

Trigynaea triplinervis 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.

Trigynaea triplinervis can be propagated through seeds, stem cuttings.

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