Pequi Plant Care

Pequi (Caryocar glabrum) belongs to the Caryocaraceae family within the Caryocar genus. Pequi is native to South America. Pequi is also known as Souari Nut.

Pequi displays a tall canopy tree growth habit, reaching up to 60 ft tall with a spread of approximately 30 ft. Pequi produces small, fragrant yellow flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Pequi 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.

Pequi thrives in full sun.

Caryocar glabrum tolerates temperatures of 65–85°F. Pequi 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 for nutrients. Good drainage is essential for Pequi to prevent waterlogging, which leads to root rot and fungal issues.

Feed Pequi every 8 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 and well-draining loamy soil with added organic matter for nutrients. Avoid low spots where water collects after rain.

Pequi is suited to USDA Zone 13b.

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.

Pequi can spread to about 30 ft (9.1 m) and reach about 60 ft (18 m) tall. Space plants about 30 ft (9.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Pequi 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.

Pequi 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.

Pequi can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to caryocar amygdaliferum plant care, which shares the same genus.

Pequi is susceptible to 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.

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