Slender Dacrydium Plant Care

Slender Dacrydium (Dacrydium gracile) belongs to the Podocarpaceae family within the Dacrydium genus.

Slender Dacrydium displays a pyramidal, conical tree growth habit, reaching up to 50 ft tall with a spread of approximately 20 ft. Slender Dacrydium produces inconspicuous, small male and female cones.

Leaf size: approximately 1.5 inches.

Water a young or newly planted Slender Dacrydium 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.

Slender Dacrydium thrives in full sun to partial shade.

Dacrydium gracile tolerates temperatures of 50–80°F. Slender Dacrydium prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining acidic soil with high organic content. Good drainage is essential for Slender Dacrydium to prevent waterlogging, which leads to root rot and fungal issues.

Feed Slender Dacrydium 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun to partial shade and well-draining acidic soil with high organic content. Avoid low spots where water collects after rain.

Slender Dacrydium 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.

Slender Dacrydium can spread to about 20 ft (6.1 m) and reach about 50 ft (15 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Slender Dacrydium 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.

Slender Dacrydium 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.

Slender Dacrydium can be propagated through seeds, cuttings. Similar propagation techniques also apply to beccari's pine plant care, which shares the same genus.

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

Slender Dacrydium grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. In cooler regions, grow Slender Dacrydium as a houseplant or bring it indoors before the first frost.
