Vitex longisepala Plant Care

Vitex longisepala (Vitex longisepala) belongs to the Lamiaceae family within the Vitex genus. Vitex longisepala is native to Peninsular Malaysia.

Vitex longisepala displays a small tree or large shrub growth habit, reaching up to 15 ft tall with a spread of approximately 10 ft. Vitex longisepala produces showy spikes of purple, blue, or white flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Vitex longisepala 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.

Vitex longisepala thrives in full sun to partial shade.

Vitex longisepala tolerates temperatures of 50–90°F. Vitex longisepala prefers humidity levels of 40–70%.

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

Feed Vitex longisepala 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.

Vitex longisepala is suited to USDA Zone 12a.

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.

Vitex longisepala 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 Vitex longisepala 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.

Vitex longisepala is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Vitex longisepala can be propagated through softwood cuttings, hardwood cuttings. Similar propagation techniques also apply to chaste tree plant care, which shares the same genus.
