Myrmecophila humboldtii Plant Care

Myrmecophila humboldtii (Myrmecophila humboldtii) belongs to the Orchidaceae family within the Myrmecophila genus.

Myrmecophila humboldtii displays an epiphytic, clumping orchid growth habit, reaching up to 2 ft tall with a spread of approximately 2 ft. Myrmecophila humboldtii produces showy, fragrant blooms in various colors.

Leaf size: approximately 12 inches.

Water a young or newly planted Myrmecophila humboldtii 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.

Myrmecophila humboldtii thrives in bright indirect to filtered sunlight. Avoid placing Myrmecophila humboldtii in direct, harsh sunlight for extended periods, as this can scorch the foliage.

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

Loose, well-draining orchid mix with bark and sphagnum moss. Good drainage is essential for Myrmecophila humboldtii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Myrmecophila humboldtii 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.

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

Choose a spot with bright indirect to filtered sunlight and loose, well-draining orchid mix with bark and sphagnum moss. Avoid low spots where water collects after rain.

Myrmecophila humboldtii 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.

Myrmecophila humboldtii can spread to about 2 ft (0.6 m) and reach about 2 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Myrmecophila humboldtii 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.

Myrmecophila humboldtii 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.

Myrmecophila humboldtii can be propagated through division, back bulbs. Similar propagation techniques also apply to giant-petaled orchid plant care, which shares the same genus.

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

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