Skimmia japonica subsp. arisanensis Plant Care

Skimmia japonica subsp. arisanensis (Skimmia japonica var. arisanensis) belongs to the Rutaceae family within the Skimmia genus. Skimmia japonica subsp. arisanensis is native to Taiwan, Japan.

Skimmia japonica subsp. arisanensis displays a compact, rounded shrub growth habit, reaching up to 3 ft tall with a spread of approximately 3 ft. Skimmia japonica subsp. arisanensis produces clusters of small, fragrant white or pink flowers.

Leaf size: approximately 3 inches.

Water a young or newly planted Skimmia japonica subsp. arisanensis every 7–14 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.

Skimmia japonica subsp. arisanensis thrives in partial shade to full shade. The optimal light range is 100–500 lux. Avoid placing Skimmia japonica subsp. arisanensis in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Skimmia japonica var. arisanensis tolerates temperatures of 50–70°F. Skimmia japonica subsp. arisanensis prefers humidity levels of 40–60%.

Well-draining, acidic soil with high organic matter content. Good drainage is essential for Skimmia japonica subsp. arisanensis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Skimmia japonica subsp. arisanensis 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 shade and well-draining, acidic soil with high organic matter content. Avoid low spots where water collects after rain.

Skimmia japonica subsp. arisanensis is suited to USDA Zone 7a – 9b.

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.

Skimmia japonica subsp. arisanensis can spread to about 3 ft (0.9 m) and reach about 3 ft (1 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Skimmia japonica subsp. arisanensis 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.

Skimmia japonica subsp. arisanensis is hardy down to USDA zone 7a, so once established it can stay outdoors through winter in that zone and warmer ones.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown shrubs need extra protection: roots in a pot freeze much more easily than roots in the ground.

Skimmia japonica subsp. arisanensis can be propagated through seeds, semi-hardwood cuttings. Similar propagation techniques also apply to japanese skimmia plant care, which shares the same genus.

Skimmia japonica subsp. arisanensis 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.

Skimmia japonica subsp. arisanensis grows outdoors in USDA Zone 7a – 9b. It survives winters down to planting zone 7a. Skimmia japonica subsp. arisanensis is native to Taiwan, Japan.
