Picramnia bullata Plant Care

Picramnia bullata (Picramnia bullata) belongs to the Picramniaceae family within the Picramnia genus.

Picramnia bullata displays a tall, slender tree growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. Picramnia bullata produces small clusters of inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Picramnia bullata 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.

Picramnia bullata thrives in full sun to partial shade.

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

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Picramnia bullata to prevent waterlogging, which leads to root rot and fungal issues.

Feed Picramnia bullata 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 sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Picramnia bullata 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.

Picramnia bullata can spread to about 15 ft (4.6 m) and reach about 30 ft (9 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Picramnia bullata 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.

Picramnia bullata 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.

Picramnia bullata can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to bitterwood plant care, which shares the same genus.

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

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