Calycolpus australis Plant Care

Calycolpus australis (Calycolpus australis) belongs to the Myrtaceae family within the Calycolpus genus. Calycolpus australis is native to the State of Minas Gerais in Brazil.

Calycolpus australis displays a compact, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Calycolpus australis produces small white or pink flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Calycolpus australis every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Calycolpus australis thrives in bright indirect light. Avoid placing Calycolpus australis in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Calycolpus australis tolerates temperatures of 60–80°F. Calycolpus australis prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added organic matter like compost or peat moss. Good drainage is essential for Calycolpus australis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Calycolpus australis every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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 bright indirect light and well-draining loamy soil with added organic matter like compost or peat moss. Avoid low spots where water collects after rain.

Calycolpus australis is suited to USDA Zone 13a.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Calycolpus australis can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Calycolpus australis 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 shrub in one year.

Calycolpus australis 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.

Calycolpus australis can be propagated through softwood cuttings, air layering.

Calycolpus australis is susceptible to aphids, 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.

Calycolpus australis grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Calycolpus australis is native to the State of Minas Gerais in Brazil. In cooler regions, grow Calycolpus australis as a houseplant or bring it indoors before the first frost.
