Spiraeanthemum katakata Plant Care

Spiraeanthemum katakata (Spiraeanthemum katakata) belongs to the Cunoniaceae family within the Spiraeanthemum genus. Spiraeanthemum katakata is native to Fiji.

Spiraeanthemum katakata displays a compact, spreading shrub growth habit, reaching up to 3 ft tall with a spread of approximately 4 ft. Spiraeanthemum katakata produces small clusters of white or pink flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Spiraeanthemum katakata 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.

Spiraeanthemum katakata thrives in partial shade to full sun.

Spiraeanthemum katakata tolerates temperatures of 60–80°F. Spiraeanthemum katakata prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with added compost for nutrients. Good drainage is essential for Spiraeanthemum katakata to prevent waterlogging, which leads to root rot and fungal issues.

Feed Spiraeanthemum katakata 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 partial shade to full sun and rich, well-draining soil with added compost for nutrients. Avoid low spots where water collects after rain.

Spiraeanthemum katakata is suited to USDA Zone 13a.

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.

Spiraeanthemum katakata can spread to about 4 ft (1.2 m) and reach about 3 ft (1 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Spiraeanthemum katakata 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.

Spiraeanthemum katakata 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.

Spiraeanthemum katakata can be propagated through softwood cuttings, air layering. Similar propagation techniques also apply to spiraeanthemum graeffei plant care, which shares the same genus.

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

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