Cannabis trema Plant Care

Cannabis trema (Trema cannabina) belongs to the Cannabaceae family within the Trema genus. Cannabis trema is native to Southeast Asia and Oceania. Cannabis trema is also known as Hemp trema, Poison peach.

Cannabis trema displays a fast-growing small tree growth habit, reaching up to 15 ft tall with a spread of approximately 10 ft. Cannabis trema produces inconspicuous greenish flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Cannabis trema every 7–10 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.

Cannabis trema thrives in full sun to partial shade.

Trema cannabina tolerates temperatures of 60–85°F. Cannabis trema prefers humidity levels of 40–70%.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Cannabis trema to prevent waterlogging, which leads to root rot and fungal issues.

Feed Cannabis trema every 6 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 loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Cannabis trema is suited to USDA Zone 10b – 12b.

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.

Cannabis trema can spread to about 10 ft (3 m) and reach about 15 ft (5 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 Cannabis trema 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.

Cannabis trema is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Cannabis trema can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to poison peach plant care, which shares the same genus.

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

Cannabis trema grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Cannabis trema is native to Southeast Asia and Oceania. In cooler regions, grow Cannabis trema as a houseplant or bring it indoors before the first frost.
