Willowleaf Conebush Plant Care

Willowleaf Conebush (Leucadendron salicifolium) belongs to the Proteaceae family within the Leucadendron genus. Willowleaf Conebush is native to the Western Cape.

Willowleaf Conebush displays an upright, bushy shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Willowleaf Conebush produces small colorful bracts surrounding the flower head.

Leaf size: approximately 4 inches.

Water a young or newly planted Willowleaf Conebush 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.

Willowleaf Conebush thrives in full sun to partial shade.

Leucadendron salicifolium tolerates temperatures of 50–80°F. Willowleaf Conebush prefers humidity levels of 40–70%.

Well-draining acidic soil mix with added sand and perlite. Good drainage is essential for Willowleaf Conebush to prevent waterlogging, which leads to root rot and fungal issues.

Feed Willowleaf Conebush 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.

Choose a spot with full sun to partial shade and well-draining acidic soil mix with added sand and perlite. Avoid low spots where water collects after rain.

Willowleaf Conebush 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.

Willowleaf Conebush 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 Willowleaf Conebush 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.

Willowleaf Conebush 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.

Willowleaf Conebush can be propagated through seeds, cuttings. Similar propagation techniques also apply to galpin's leucadendron plant care, which shares the same genus.

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

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