Apostasia wallichii Plant Care

Apostasia wallichii (Apostasia wallichii) belongs to the Orchidaceae family within the Apostasia genus. Apostasia wallichii is native to India, Japan, China, Southeast Asia, New Guinea and northern Australia.

Apostasia wallichii displays an upright, clumping growth habit, reaching up to 1.5 ft tall with a spread of approximately 1 ft. Apostasia wallichii produces small, delicate blooms in various colors.

Leaf size: approximately 6 inches.

Water a young or newly planted Apostasia wallichii 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.

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

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

Loose, well-draining orchid mix with bark and perlite. Good drainage is essential for Apostasia wallichii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Apostasia wallichii 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 bright indirect light and loose, well-draining orchid mix with bark and perlite. Avoid low spots where water collects after rain.

Apostasia wallichii 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.

Apostasia wallichii can spread to about 1 ft (0.3 m) and reach about 2 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Apostasia wallichii 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.

Apostasia wallichii 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.

Apostasia wallichii can be propagated through division, keiki propagation. Similar propagation techniques also apply to leafless orchid plant care, which shares the same genus.

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

Apostasia wallichii grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Apostasia wallichii is native to India, Japan, China, Southeast Asia, New Guinea and northern Australia. In cooler regions, grow Apostasia wallichii as a houseplant or bring it indoors before the first frost.
