Christmas holly Plant Care

Christmas holly (Ilex anomala) belongs to the Aquifoliaceae family within the Ilex genus. Christmas holly is native to the Hawaiian Islands and the Marquesas Islands and Society Islands of French Polynesia. Christmas holly is also known as Chinese holly.

Christmas holly displays an upright, dense shrub or small tree growth habit, reaching up to 15 ft tall with a spread of approximately 10 ft. Christmas holly produces small white flowers in clusters, followed by red berries.

Leaf size: approximately 3 inches.

Water a young or newly planted Christmas holly 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.

Christmas holly thrives in full sun to part shade.

Ilex anomala tolerates temperatures of 50–80°F. Christmas holly prefers humidity levels of 40–70%.

Moist, well-draining soil rich in organic matter. Good drainage is essential for Christmas holly to prevent waterlogging, which leads to root rot and fungal issues.

Feed Christmas holly 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 full sun to part shade and moist, well-draining soil rich in organic matter. Avoid low spots where water collects after rain.

Christmas holly is suited to USDA Zone 9b – 11b.

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.

Christmas holly can spread to about 10 ft (3 m) and reach about 15 ft (5 m) tall. Space plants about 10 ft (3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Christmas holly 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.

Christmas holly is frost-tender (hardy to USDA zone 9). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Christmas holly can be propagated through seeds, semi-hardwood cuttings. Similar propagation techniques also apply to european holly plant care, which shares the same genus.

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

Christmas holly grows outdoors in USDA Zone 9b – 11b. It survives winters down to planting zone 9b. Christmas holly is native to the Hawaiian Islands and the Marquesas Islands and Society Islands of French Polynesia. In cooler regions, grow Christmas holly as a houseplant or bring it indoors before the first frost.
