Stinking Juniper Plant Care

Stinking Juniper (Juniperus foetidissima) belongs to the Cupressaceae family within the Juniperus genus. Stinking Juniper is also known as Fetid Juniper.

Stinking Juniper displays an upright, conical tree or shrub growth habit, reaching up to 20 ft tall with a spread of approximately 10 ft. Stinking Juniper produces small cones rather than traditional flowers.

Water a young or newly planted Stinking Juniper every 14–21 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.

Stinking Juniper thrives in full sun to part shade.

Juniperus foetidissima tolerates temperatures of 0–100°F. Stinking Juniper prefers humidity levels of 30–60%.

Well-draining sandy soil with good aeration. Good drainage is essential for Stinking Juniper to prevent waterlogging, which leads to root rot and fungal issues.

Feed Stinking Juniper every 8 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 part shade and well-draining sandy soil with good aeration. Avoid low spots where water collects after rain.

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.

Stinking Juniper can spread to about 10 ft (3 m) and reach about 20 ft (6 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 Stinking Juniper 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.

Water deeply in late autumn before the ground freezes — evergreens keep losing water through their needles all winter, 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 trees need extra protection: roots in a pot freeze much more easily than roots in the ground.

Stinking Juniper can be propagated through seeds, cuttings, layering. Similar propagation techniques also apply to common juniper plant care, which shares the same genus.

Stinking Juniper is susceptible to spider mites, scale insects, juniper twig blight. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.
