Golden Larch Plant Care

Golden Larch (Pseudolarix amabilis) belongs to the Pinaceae family within the Pseudolarix genus. Golden Larch is native to eastern China, occurring in small areas in the mountains of southern Anhui, Zhejiang, Fujian, Jiangxi, Hunan, Hubei and eastern Sichuan, at altitudes of 100–1,500 m (328–4,921 ft).

Golden Larch displays a pyramidal, conical tree growth habit, reaching up to 60 ft tall with a spread of approximately 20 ft. Golden Larch produces insignificant, monoecious.

Leaf size: approximately 3 inches.

Water a young or newly planted Golden Larch 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.

Golden Larch thrives in full sun to partial shade.

Pseudolarix amabilis tolerates temperatures of 0–90°F. Golden Larch prefers humidity levels of 40–70%.

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

Feed Golden Larch 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 partial shade and well-draining, acidic soil with good organic content. 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.

Golden Larch can spread to about 20 ft (6.1 m) and reach about 60 ft (18 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.

Golden Larch needs little pruning. Remove dead, damaged or crossing branches in late winter or early spring.

Don't cut back into old, bare wood: conifers in the pine family rarely sprout new growth from it. To keep a denser shape, trim only the soft new shoots in late spring.

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.

Golden Larch can be propagated through seeds, grafting.

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