Lagerstroemia duperreana Plant Care

Lagerstroemia duperreana (Lagerstroemia duperreana) belongs to the Lythraceae family within the Lagerstroemia genus. Lagerstroemia duperreana is native to Indochina, including in southern Vietnam, Laos, Thailand, and Cambodia.

Lagerstroemia duperreana displays a small to medium-sized tree growth habit, reaching up to 20 ft tall with a spread of approximately 15 ft. Lagerstroemia duperreana produces showy clusters of pink, purple, white, or red flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Lagerstroemia duperreana every 7–10 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.

Lagerstroemia duperreana thrives in full sun to partial shade.

Lagerstroemia duperreana tolerates temperatures of 60–90°F. Lagerstroemia duperreana prefers humidity levels of 40–70%.

Well-draining, slightly acidic soil with good organic content. Good drainage is essential for Lagerstroemia duperreana to prevent waterlogging, which leads to root rot and fungal issues.

Feed Lagerstroemia duperreana 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.

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

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

Lagerstroemia duperreana 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.

Lagerstroemia duperreana can spread to about 15 ft (4.6 m) and reach about 20 ft (6 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 Lagerstroemia duperreana 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.

Lagerstroemia duperreana 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.

Lagerstroemia duperreana can be propagated through seeds, softwood cuttings. Similar propagation techniques also apply to crepe myrtle plant care, which shares the same genus.

Lagerstroemia duperreana is susceptible to aphids, scale insects, powdery mildew. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Lagerstroemia duperreana grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Lagerstroemia duperreana is native to Indochina, including in southern Vietnam, Laos, Thailand, and Cambodia. In cooler regions, grow Lagerstroemia duperreana as a houseplant or bring it indoors before the first frost.
