Singaporandia macrophylla Plant Care

Singaporandia macrophylla (Singaporandia macrophylla) belongs to the Rubiaceae family within the Singaporandia genus.

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

Leaf size: approximately 4 inches.

Water a young or newly planted Singaporandia macrophylla 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.

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

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

Rich, well-draining potting mix with added peat moss and perlite. Good drainage is essential for Singaporandia macrophylla to prevent waterlogging, which leads to root rot and fungal issues.

Feed Singaporandia macrophylla 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 rich, well-draining potting mix with added peat moss and perlite. Avoid low spots where water collects after rain.

Singaporandia macrophylla 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.

Singaporandia macrophylla 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 Singaporandia macrophylla 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.

Singaporandia macrophylla 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.

Singaporandia macrophylla can be propagated through stem cuttings, air layering, division.

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