Hairy Crape Myrtle Plant Care

Hairy Crape Myrtle (Lagerstroemia tomentosa) belongs to the Lythraceae family within the Lagerstroemia genus. Hairy Crape Myrtle is native to Indochina, including in Yunnan (China), Vietnam, Laos, Thailand, and Cambodia. Hairy Crape Myrtle is also known as Woolly Crape Myrtle.

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

Leaf size: approximately 4 inches.

Water a young or newly planted Hairy Crape Myrtle 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.

Hairy Crape Myrtle thrives in full sun to partial shade.

Lagerstroemia tomentosa tolerates temperatures of 60–90°F. Hairy Crape Myrtle prefers humidity levels of 40–70%.

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

Feed Hairy Crape Myrtle 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.

Hairy Crape Myrtle 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.

Hairy Crape Myrtle 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 Hairy Crape Myrtle 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.

Hairy Crape Myrtle 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.

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