Tree Mallow Plant Care

Tree Mallow (Azanza lampas) belongs to the Malvaceae family within the Azanza genus. Tree Mallow is also known as Malvaviscus lampas.

Tree Mallow displays a fast-growing shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Tree Mallow produces showy, colorful trumpet-shaped flowers.

Leaf size: approximately 8 inches.

Water a young or newly planted Tree Mallow every 5–7 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.

Tree Mallow thrives in full sun to partial shade.

Azanza lampas tolerates temperatures of 60–85°F. Tree Mallow prefers humidity levels of 40–70%.

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

Feed Tree Mallow 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 mix with added compost for nutrients. Avoid low spots where water collects after rain.

Tree Mallow 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.

Tree Mallow 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 Tree Mallow 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.

Tree Mallow 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.

Tree Mallow can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to false mallow plant care, which shares the same genus.

Tree Mallow is susceptible to aphids, whiteflies, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

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