Guarea casimiriana Plant Care

Guarea casimiriana (Guarea casimiriana) belongs to the Meliaceae family within the Guarea genus. Guarea casimiriana is native to Peru.

Guarea casimiriana displays a tall tree, spreading canopy growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Guarea casimiriana produces small clusters of white or cream-colored flowers.

Leaf size: approximately 8 inches.

Water a young or newly planted Guarea casimiriana 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.

Guarea casimiriana thrives in partial shade to full sun.

Guarea casimiriana tolerates temperatures of 60–85°F. Guarea casimiriana prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with added compost for nutrients. Good drainage is essential for Guarea casimiriana to prevent waterlogging, which leads to root rot and fungal issues.

Feed Guarea casimiriana 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 rich, well-draining soil with added compost for nutrients. Avoid low spots where water collects after rain.

Guarea casimiriana 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.

Guarea casimiriana 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 Guarea casimiriana 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.

Guarea casimiriana 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.

Guarea casimiriana can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to guarea carapoides plant care, which shares the same genus.

Guarea casimiriana 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.

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