Astiria rosea Plant Care

Astiria rosea (Astiria rosea) belongs to the Malvaceae family within the Astiria genus. Astiria rosea is native to Mauritius.

Astiria rosea displays a compact, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Astiria rosea produces large, showy blooms in various colors.

Leaf size: approximately 6 inches.

Water a young or newly planted Astiria rosea 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.

Astiria rosea thrives in full sun to partial shade.

Astiria rosea tolerates temperatures of 65–80°F. Astiria rosea prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Astiria rosea to prevent waterlogging, which leads to root rot and fungal issues.

Feed Astiria rosea every 4 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 full sun to partial shade and well-draining loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Astiria rosea 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.

Astiria rosea 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 Astiria rosea 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.

Astiria rosea 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.

Astiria rosea can be propagated through seeds, stem cuttings.

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