Acer oligocarpum Plant Care

Acer oligocarpum (Acer oligocarpum) belongs to the Sapindaceae family within the Acer genus.

Acer oligocarpum displays an upright, spreading tree growth habit, reaching up to 30 ft tall with a spread of approximately 25 ft. Acer oligocarpum produces small inconspicuous flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Acer oligocarpum 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.

Acer oligocarpum thrives in full sun to partial shade.

Acer oligocarpum tolerates temperatures of 0–100°F. Acer oligocarpum prefers humidity levels of 40–70%.

Rich, well-draining soil with plenty of organic matter. Good drainage is essential for Acer oligocarpum to prevent waterlogging, which leads to root rot and fungal issues.

Feed Acer oligocarpum 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 rich, well-draining soil with plenty of organic matter. 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.

Acer oligocarpum can spread to about 25 ft (7.6 m) and reach about 30 ft (9 m) tall. Space plants about 25 ft (7.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Acer oligocarpum 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, 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.

Acer oligocarpum can be propagated through seeds, softwood cuttings. Similar propagation techniques also apply to sugar maple tree plant care, which shares the same genus.

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