Mendoncia puberula Plant Care

Mendoncia puberula (Mendoncia puberula) belongs to the Acanthaceae family within the Mendoncia genus. Mendoncia puberula is native to tropical South America, ranging from Venezuela, Colombia, and Ecuador through northern, central, and southern Brazil.

Mendoncia puberula displays a bushy, spreading shrub growth habit, reaching up to 3 ft tall with a spread of approximately 4 ft. Mendoncia puberula produces tubular flowers in various colors like red, pink, purple, or white.

Leaf size: approximately 6 inches.

Water a young or newly planted Mendoncia puberula 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.

Mendoncia puberula thrives in bright indirect light. Avoid placing Mendoncia puberula in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Mendoncia puberula tolerates temperatures of 65–80°F. Mendoncia puberula prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, fertile soil with added organic matter like compost or peat moss. Good drainage is essential for Mendoncia puberula to prevent waterlogging, which leads to root rot and fungal issues.

Feed Mendoncia puberula every 4 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.

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

Choose a spot with bright indirect light and well-draining, fertile soil with added organic matter like compost or peat moss. Avoid low spots where water collects after rain.

Mendoncia puberula is suited to USDA Zone 13b.

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.

Mendoncia puberula 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 Mendoncia puberula 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.

Mendoncia puberula 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.

Mendoncia puberula can be propagated through stem cuttings, division, seeds. Similar propagation techniques also apply to mendoncia mollis plant care, which shares the same genus.

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

Mendoncia puberula grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Mendoncia puberula is native to tropical South America, ranging from Venezuela, Colombia, and Ecuador through northern, central, and southern Brazil. In cooler regions, grow Mendoncia puberula as a houseplant or bring it indoors before the first frost.
