Ascarina coursii Plant Care

Ascarina coursii (Ascarina coursii) belongs to the Chloranthaceae family within the Ascarina genus. Ascarina coursii is native to Madagascar.

Ascarina coursii displays a small tree or shrub growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Ascarina coursii produces small, inconspicuous flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Ascarina coursii 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.

Ascarina coursii thrives in partial to full shade. The optimal light range is 100–500 lux. Avoid placing Ascarina coursii in direct, harsh sunlight for extended periods, as this can scorch the foliage.

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

Rich, well-draining soil with high organic content. Good drainage is essential for Ascarina coursii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Ascarina coursii 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.

Choose a spot with partial to full shade and rich, well-draining soil with high organic content. Avoid low spots where water collects after rain.

Ascarina coursii 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.

Ascarina coursii 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 Ascarina coursii 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.

Ascarina coursii 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.

Ascarina coursii can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to new zealand jasmine plant care, which shares the same genus.

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

Ascarina coursii grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Ascarina coursii is native to Madagascar. In cooler regions, grow Ascarina coursii as a houseplant or bring it indoors before the first frost.
