Three-lobed Louiseania Plant Care

Three-lobed Louiseania (Louiseania triloba) belongs to the Rosaceae family within the Louiseania genus. Three-lobed Louiseania is native to China.

Three-lobed Louiseania displays a compact, spreading shrub growth habit, reaching up to 3 ft tall with a spread of approximately 4 ft. Three-lobed Louiseania produces small, fragrant white or pink clustered blooms.

Leaf size: approximately 4 inches.

Water a young or newly planted Three-lobed Louiseania 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.

Three-lobed Louiseania thrives in full sun to partial shade.

Louiseania triloba tolerates temperatures of 60–75°F. Three-lobed Louiseania prefers humidity levels of 40–60%.

Rich, well-draining loamy soil with added compost for nutrients. Good drainage is essential for Three-lobed Louiseania to prevent waterlogging, which leads to root rot and fungal issues.

Feed Three-lobed Louiseania 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.

Choose a spot with full sun to partial shade and rich, well-draining loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Three-lobed Louiseania is suited to USDA Zone 13a.

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.

Three-lobed Louiseania can spread to about 4 ft (1.2 m) and reach about 3 ft (1 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 Three-lobed Louiseania 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.

Three-lobed Louiseania 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.

Three-lobed Louiseania can be propagated through softwood cuttings, division of offsets, seeds.

Three-lobed Louiseania 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.

Three-lobed Louiseania grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Three-lobed Louiseania is native to China. In cooler regions, grow Three-lobed Louiseania as a houseplant or bring it indoors before the first frost.
