Masters Larch Plant Care

Masters Larch (Larix mastersiana) belongs to the Pinaceae family within the Larix genus.

Masters Larch displays a tall, conical tree growth habit, reaching up to 60 ft tall with a spread of approximately 20 ft. Masters Larch produces small, inconspicuous cones.

Leaf size: approximately 1 inches.

Water a young or newly planted Masters 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.

Masters Larch thrives in full sun.

Larix mastersiana tolerates temperatures of 0–70°F. Masters Larch prefers humidity levels of 40–70%.

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

Choose a spot with full sun and well-draining loamy 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.

Masters 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.

Masters 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.

Masters Larch can be propagated through seeds, grafting. Similar propagation techniques also apply to european larch plant care, which shares the same genus.

Masters Larch is susceptible to aphids, bark beetles, 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.
