Guanandi Plant Care

Guanandi (Cariniana legalis) belongs to the Lecythidaceae family within the Cariniana genus. Guanandi is native to the Atlantic forest of south-eastern Brazil. Guanandi is also known as Jequitiba-rosa.

Guanandi displays a tall canopy tree growth habit, reaching up to 100 ft tall with a spread of approximately 50 ft. Guanandi produces small, inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Guanandi 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.

Guanandi thrives in full sun to partial shade.

Cariniana legalis tolerates temperatures of 65–85°F. Guanandi prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with added organic matter like compost or leaf mold. Good drainage is essential for Guanandi to prevent waterlogging, which leads to root rot and fungal issues.

Feed Guanandi 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 rich, well-draining soil with added organic matter like compost or leaf mold. Avoid low spots where water collects after rain.

Guanandi 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.

Guanandi can spread to about 50 ft (15.2 m) and reach about 100 ft (30 m) tall. Space plants about 50 ft (15.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Guanandi 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.

Guanandi 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.

Guanandi can be propagated through seeds, air layering. Similar propagation techniques also apply to guanandi plant care, which shares the same genus.

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

Guanandi grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Guanandi is native to the Atlantic forest of south-eastern Brazil. In cooler regions, grow Guanandi as a houseplant or bring it indoors before the first frost.
