Copál Plant Care

Copál (Protium confusum) belongs to the Burseraceae family within the Protium genus. Copál is native to southeastern Mexico, Guatemala, Belize, Honduras, Nicaragua, Costa Rica, and Panama.

Copál displays a tall tree, upright growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. Copál produces small, inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Copál 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.

Copál thrives in full sun to partial shade.

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

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

Feed Copál 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 full sun to partial shade and well-draining soil mix with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Copál 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.

Copál can spread to about 15 ft (4.6 m) and reach about 30 ft (9 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Copál 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.

Copál 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.

Copál can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to bursera attenuata plant care, which shares the same genus.

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

Copál grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Copál is native to southeastern Mexico, Guatemala, Belize, Honduras, Nicaragua, Costa Rica, and Panama. In cooler regions, grow Copál as a houseplant or bring it indoors before the first frost.
