Spathiostemon moniliformis Plant Care

Spathiostemon moniliformis (Spathiostemon moniliformis) belongs to the Euphorbiaceae family within the Spathiostemon genus. Spathiostemon moniliformis is native to southern/peninsular Thailand.

Spathiostemon moniliformis displays a tall, upright tree growth habit, reaching up to 10 ft tall with a spread of approximately 5 ft. Spathiostemon moniliformis produces small, inconspicuous flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Spathiostemon moniliformis every 7–10 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.

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

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

Well-draining soil mix with high organic content, such as a mix of peat moss, perlite, and pine bark. Good drainage is essential for Spathiostemon moniliformis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Spathiostemon moniliformis 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 bright indirect light and well-draining soil mix with high organic content, such as a mix of peat moss, perlite, and pine bark. Avoid low spots where water collects after rain.

Spathiostemon moniliformis is suited to USDA Zone 13b.

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.

Spathiostemon moniliformis can spread to about 5 ft (1.5 m) and reach about 10 ft (3 m) tall. Space plants about 5 ft (1.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Spathiostemon moniliformis 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.

Spathiostemon moniliformis 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.

Spathiostemon moniliformis can be propagated through stem cuttings, air layering.

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

Spathiostemon moniliformis grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Spathiostemon moniliformis is native to southern/peninsular Thailand. In cooler regions, grow Spathiostemon moniliformis as a houseplant or bring it indoors before the first frost.
