Atalantia simplicifolia Plant Care

Atalantia simplicifolia (Atalantia simplicifolia) belongs to the Rutaceae family within the Atalantia genus.

Atalantia simplicifolia displays a small tree, spreading canopy growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Atalantia simplicifolia produces small white fragrant flowers.

Leaf size: approximately 3 inches.

Water a young or newly planted Atalantia simplicifolia 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.

Atalantia simplicifolia thrives in full sun to partial shade.

Atalantia simplicifolia tolerates temperatures of 55–85°F. Atalantia simplicifolia prefers humidity levels of 40–70%.

Well-draining loamy soil with added sand and organic matter. Good drainage is essential for Atalantia simplicifolia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Atalantia simplicifolia 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 loamy soil with added sand and organic matter. Avoid low spots where water collects after rain.

Atalantia simplicifolia is suited to USDA Zone 12b.

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.

Atalantia simplicifolia 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 Atalantia simplicifolia 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.

Atalantia simplicifolia is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Atalantia simplicifolia can be propagated through seeds, cuttings. Similar propagation techniques also apply to box-leaf atalantia plant care, which shares the same genus.

Atalantia simplicifolia is susceptible to citrus leaf miner, citrus psyllid, scale insects. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Atalantia simplicifolia grows outdoors in USDA Zone 12b. It survives winters down to planting zone 12b. In cooler regions, grow Atalantia simplicifolia as a houseplant or bring it indoors before the first frost.
