Lecythis ampla Plant Care

Lecythis ampla (Lecythis ampla) belongs to the Lecythidaceae family within the Lecythis genus. Lecythis ampla is native to Central and South America.

Lecythis ampla displays a tall canopy tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Lecythis ampla produces large showy flowers with unique shape and color.

Leaf size: approximately 12 inches.

Water a young or newly planted Lecythis ampla 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.

Lecythis ampla thrives in partial to full sun.

Lecythis ampla tolerates temperatures of 65–85°F. Lecythis ampla prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, rich loamy soil with added organic matter for moisture retention. Good drainage is essential for Lecythis ampla to prevent waterlogging, which leads to root rot and fungal issues.

Feed Lecythis ampla 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 to full sun and well-draining, rich loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Lecythis ampla is suited to USDA Zone 11a – 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.

Lecythis ampla 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 Lecythis ampla 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.

Lecythis ampla is frost-tender (hardy to USDA zone 11). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Lecythis ampla can be propagated through seeds, air layering. Similar propagation techniques also apply to lecythis barnebyi plant care, which shares the same genus.

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

Lecythis ampla grows outdoors in USDA Zone 11a – 12b. It survives winters down to planting zone 11a. Lecythis ampla is native to Central and South America. In cooler regions, grow Lecythis ampla as a houseplant or bring it indoors before the first frost.
