Montanoa atriplicifolia Plant Care

Montanoa atriplicifolia (Montanoa atriplicifolia) belongs to the Asteraceae family within the Montanoa genus.

Montanoa atriplicifolia displays a tall, upright shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Montanoa atriplicifolia produces small, daisy-like white flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Montanoa atriplicifolia 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.

Montanoa atriplicifolia thrives in full sun to partial shade.

Montanoa atriplicifolia tolerates temperatures of 60–80°F. Montanoa atriplicifolia prefers humidity levels of 40–70%.

Well-draining soil mix with added perlite for improved drainage. Good drainage is essential for Montanoa atriplicifolia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Montanoa atriplicifolia 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 soil mix with added perlite for improved drainage. Avoid low spots where water collects after rain.

Montanoa atriplicifolia 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.

Montanoa atriplicifolia 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 Montanoa atriplicifolia 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.

Montanoa atriplicifolia 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.

Montanoa atriplicifolia can be propagated through seeds, stem cuttings.

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