Hemmantia webbii Plant Care

Hemmantia webbii (Hemmantia webbii) belongs to the Monimiaceae family within the Hemmantia genus.

Hemmantia webbii displays a tall, upright tree growth habit, reaching up to 15 ft tall with a spread of approximately 8 ft. Hemmantia webbii produces small, inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Hemmantia webbii 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.

Hemmantia webbii thrives in partial to full shade. The optimal light range is 100–500 lux. Avoid placing Hemmantia webbii in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Hemmantia webbii tolerates temperatures of 60–80°F. Hemmantia webbii prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with added organic matter like compost or peat moss. Good drainage is essential for Hemmantia webbii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Hemmantia webbii 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 partial to full shade and rich, well-draining soil with added organic matter like compost or peat moss. Avoid low spots where water collects after rain.

Hemmantia webbii is suited to USDA Zone 13a.

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.

Hemmantia webbii can spread to about 8 ft (2.4 m) and reach about 15 ft (5 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Hemmantia webbii 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.

Hemmantia webbii is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Hemmantia webbii can be propagated through seeds, stem cuttings.

Hemmantia webbii grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. In cooler regions, grow Hemmantia webbii as a houseplant or bring it indoors before the first frost.
