Pseudoxandra williamsii Plant Care

Pseudoxandra williamsii (Pseudoxandra williamsii) belongs to the Annonaceae family within the Pseudoxandra genus. Pseudoxandra williamsii is native to Peru.

Pseudoxandra williamsii displays a compact, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Pseudoxandra williamsii produces small, fragrant white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Pseudoxandra williamsii every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Pseudoxandra williamsii thrives in partial shade to full sun.

Pseudoxandra williamsii tolerates temperatures of 65–80°F. Pseudoxandra williamsii prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

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

Feed Pseudoxandra williamsii every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with partial shade to full sun and rich, well-draining soil with organic matter. Avoid low spots where water collects after rain.

Pseudoxandra williamsii is suited to USDA Zone 13b.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Pseudoxandra williamsii can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Pseudoxandra williamsii 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 shrub in one year.

Pseudoxandra williamsii 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.

Pseudoxandra williamsii can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to pseudoxandra leiophylla plant care, which shares the same genus.

Pseudoxandra williamsii is susceptible to 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.

Pseudoxandra williamsii grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Pseudoxandra williamsii is native to Peru. In cooler regions, grow Pseudoxandra williamsii as a houseplant or bring it indoors before the first frost.
