Chiloglottis Plant Care

Chiloglottis (Eriochilus dilatatus subsp. dilatatus) belongs to the Orchidaceae family within the Eriochilus genus. Chiloglottis is native to Western Australia. Chiloglottis is also known as Dilated Bird Orchid.

Chiloglottis displays an upright, clumping growth habit, reaching up to 1.5 ft tall with a spread of approximately 1 ft. Chiloglottis produces small, colorful orchid blooms.

Leaf size: approximately 6 inches.

Water a young or newly planted Chiloglottis 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.

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

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

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

Feed Chiloglottis 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 light and well-draining orchid mix with bark and perlite. Avoid low spots where water collects after rain.

Chiloglottis 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.

Chiloglottis 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 Chiloglottis 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.

Chiloglottis 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.

Chiloglottis can be propagated through division, seed sowing. Similar propagation techniques also apply to chiloglottis plant care, which shares the same genus.

Chiloglottis 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.

Chiloglottis grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Chiloglottis is native to Western Australia. In cooler regions, grow Chiloglottis as a houseplant or bring it indoors before the first frost.
