Pine-leaved Goldenbush Plant Care

Pine-leaved Goldenbush (Ericameria resinosa) belongs to the Asteraceae family within the Ericameria genus. Pine-leaved Goldenbush is native to the northwestern part of the United States, in the states of Washington, Oregon, and Idaho. Pine-leaved Goldenbush is also known as Pineleaf Goldenbush, Aster resinosus, Chrysothamnus resinosus.

Pine-leaved Goldenbush displays an upright, branching shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Pine-leaved Goldenbush produces small yellow flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Pine-leaved Goldenbush every 10–14 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.

Pine-leaved Goldenbush thrives in full sun.

Ericameria resinosa tolerates temperatures of 50–85°F. Pine-leaved Goldenbush prefers humidity levels of 20–60%.

Well-draining sandy soil with low fertility. Good drainage is essential for Pine-leaved Goldenbush to prevent waterlogging, which leads to root rot and fungal issues.

Feed Pine-leaved Goldenbush 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 full sun and well-draining sandy soil with low fertility. Avoid low spots where water collects after rain.

Pine-leaved Goldenbush is suited to USDA Zone 12a.

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.

Pine-leaved Goldenbush can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Pine-leaved Goldenbush 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.

Pine-leaved Goldenbush 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.

Pine-leaved Goldenbush can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to cooper's goldenbush plant care, which shares the same genus.

Pine-leaved Goldenbush is susceptible to aphids, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Pine-leaved Goldenbush grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Pine-leaved Goldenbush is native to the northwestern part of the United States, in the states of Washington, Oregon, and Idaho. In cooler regions, grow Pine-leaved Goldenbush as a houseplant or bring it indoors before the first frost.
