Symplocos shilanensis Plant Care

Symplocos shilanensis (Symplocos shilanensis) belongs to the Symplocaceae family within the Symplocos genus. Symplocos shilanensis is native to Taiwan.

Symplocos shilanensis displays an upright, spreading shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Symplocos shilanensis produces small, fragrant white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Symplocos shilanensis 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.

Symplocos shilanensis thrives in partial shade to full sun.

Symplocos shilanensis tolerates temperatures of 50–85°F. Symplocos shilanensis prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining acidic soil with high organic content. Good drainage is essential for Symplocos shilanensis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Symplocos shilanensis 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 partial shade to full sun and well-draining acidic soil with high organic content. Avoid low spots where water collects after rain.

Symplocos shilanensis is suited to USDA Zone 12a.

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.

Symplocos shilanensis can spread to about 4 ft (1.2 m) and reach about 6 ft (2 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 Symplocos shilanensis 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.

Symplocos shilanensis is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Symplocos shilanensis can be propagated through seeds, softwood cuttings. Similar propagation techniques also apply to white sourwood plant care, which shares the same genus.

Symplocos shilanensis 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.

Symplocos shilanensis grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Symplocos shilanensis is native to Taiwan. In cooler regions, grow Symplocos shilanensis as a houseplant or bring it indoors before the first frost.
