Myrciaria alagoana Plant Care

Myrciaria alagoana (Myrciaria alagoana) belongs to the Myrtaceae family within the Myrciaria genus. Myrciaria alagoana is native to the state of Alagoas in the east of Brazil.

Myrciaria alagoana displays a small tree or shrub growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Myrciaria alagoana produces small white or pink fragrant flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Myrciaria alagoana every 7–10 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.

Myrciaria alagoana thrives in full sun to partial shade.

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

Well-draining acidic soil with high organic content. Good drainage is essential for Myrciaria alagoana to prevent waterlogging, which leads to root rot and fungal issues.

Feed Myrciaria alagoana 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 acidic soil with high organic content. Avoid low spots where water collects after rain.

Myrciaria alagoana 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.

Myrciaria alagoana can spread to about 8 ft (2.4 m) and reach about 10 ft (3 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Myrciaria alagoana 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.

Myrciaria alagoana 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.

Myrciaria alagoana can be propagated through seeds, cuttings. Similar propagation techniques also apply to borinquen myrtle plant care, which shares the same genus.

Myrciaria alagoana is susceptible to fruit flies, caterpillars. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Myrciaria alagoana grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Myrciaria alagoana is native to the state of Alagoas in the east of Brazil. In cooler regions, grow Myrciaria alagoana as a houseplant or bring it indoors before the first frost.
