Santiria tomentosa Plant Care

Santiria tomentosa (Santiria tomentosa) belongs to the Burseraceae family within the Santiria genus. Santiria tomentosa is native to Indonesia, Malaysia, the Philippines, and Singapore.

Santiria tomentosa displays a tall, elegant tree growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. Santiria tomentosa produces small, inconspicuous flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Santiria tomentosa 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.

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

Santiria tomentosa tolerates temperatures of 65–80°F. Santiria tomentosa 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 blend of peat moss, perlite, and pine bark. Good drainage is essential for Santiria tomentosa to prevent waterlogging, which leads to root rot and fungal issues.

Feed Santiria tomentosa 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 blend of peat moss, perlite, and pine bark. Avoid low spots where water collects after rain.

Santiria tomentosa 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.

Santiria tomentosa can spread to about 15 ft (4.6 m) and reach about 30 ft (9 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Santiria tomentosa 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.

Santiria tomentosa 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.

Santiria tomentosa can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to santiria apiculata plant care, which shares the same genus.

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

Santiria tomentosa grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Santiria tomentosa is native to Indonesia, Malaysia, the Philippines, and Singapore. In cooler regions, grow Santiria tomentosa as a houseplant or bring it indoors before the first frost.
