White Ehretia Plant Care

White Ehretia (Ehretia alba) belongs to the Boraginaceae family within the Ehretia genus.

White Ehretia displays a small tree or shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. White Ehretia produces small white or pink tubular flowers in clusters.

Leaf size: approximately 3 inches.

Water a young or newly planted White Ehretia 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.

White Ehretia thrives in full sun to partial shade.

Ehretia alba tolerates temperatures of 60–85°F. White Ehretia prefers humidity levels of 40–70%.

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

Feed White Ehretia 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.

White Ehretia 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.

White Ehretia can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune White Ehretia 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.

White Ehretia 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.

White Ehretia can be propagated through seeds, semi-hardwood cuttings. Similar propagation techniques also apply to anacua plant care, which shares the same genus.

White Ehretia 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.

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