White Macbridea Plant Care

White Macbridea (Macbridea alba) belongs to the Lamiaceae family within the Macbridea genus. White Macbridea is native to four counties in the Florida Panhandle.

White Macbridea displays a low rosette, clumping growth habit, reaching up to 1.5 ft tall with a spread of approximately 1.5 ft. White Macbridea produces showy tubular flowers in shades of pink, purple, or white.

Leaf size: approximately 6 inches.

Water a young or newly planted White Macbridea 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.

White Macbridea thrives in full sun to partial shade.

Macbridea alba tolerates temperatures of 60–80°F. White Macbridea prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for White Macbridea to prevent waterlogging, which leads to root rot and fungal issues.

Feed White Macbridea 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 well-draining sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

White Macbridea 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.

White Macbridea can spread to about 2 ft (0.5 m) and reach about 2 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune White Macbridea 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.

White Macbridea 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.

White Macbridea can be propagated through seeds, division of clumps. Similar propagation techniques also apply to carolina bog mint plant care, which shares the same genus.

White Macbridea 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.

White Macbridea grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. White Macbridea is native to four counties in the Florida Panhandle. In cooler regions, grow White Macbridea as a houseplant or bring it indoors before the first frost.
