Argophyllum lejourdanii Plant Care

Argophyllum lejourdanii (Argophyllum lejourdanii) belongs to the Argophyllaceae family within the Argophyllum genus. Argophyllum lejourdanii is native to a part of north eastern Queensland, Australia.

Argophyllum lejourdanii displays a compact, bushy shrub growth habit, reaching up to 2.5 ft tall with a spread of approximately 2.5 ft. Argophyllum lejourdanii produces small white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Argophyllum lejourdanii 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.

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

Argophyllum lejourdanii tolerates temperatures of 65–75°F. Argophyllum lejourdanii prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining sandy soil mix with added peat moss and perlite. Good drainage is essential for Argophyllum lejourdanii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Argophyllum lejourdanii 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with bright indirect light and well-draining sandy soil mix with added peat moss and perlite. Avoid low spots where water collects after rain.

Argophyllum lejourdanii is suited to USDA Zone 13b.

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.

Argophyllum lejourdanii can spread to about 3 ft (0.8 m) and reach about 3 ft (1 m) tall. Space plants about 3 ft (0.8 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Argophyllum lejourdanii 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.

Argophyllum lejourdanii 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.

Argophyllum lejourdanii can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to argophyllum cryptophlebum plant care, which shares the same genus.

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

Argophyllum lejourdanii grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Argophyllum lejourdanii is native to a part of north eastern Queensland, Australia. In cooler regions, grow Argophyllum lejourdanii as a houseplant or bring it indoors before the first frost.
