Aquilaria secundaria Plant Care

Aquilaria secundaria (Aquilaria secundaria) belongs to the Thymelaeaceae family within the Aquilaria genus. Aquilaria secundaria is native to Bangladesh, Bhutan, India, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, also Thailand.

Aquilaria secundaria displays a tall, slender tree growth habit, reaching up to 30 ft tall with a spread of approximately 10 ft. Aquilaria secundaria produces small, inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Aquilaria secundaria every 7–14 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.

Aquilaria secundaria thrives in partial shade to full sun.

Aquilaria secundaria tolerates temperatures of 65–85°F. Aquilaria secundaria prefers humidity levels of 50–80%. 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 Aquilaria secundaria to prevent waterlogging, which leads to root rot and fungal issues.

Feed Aquilaria secundaria every 8 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.

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

Choose a spot with partial shade to full sun and well-draining sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Aquilaria secundaria is suited to USDA Zone 10b – 12b.

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.

Aquilaria secundaria can spread to about 10 ft (3 m) and reach about 30 ft (9 m) tall. Space plants about 10 ft (3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Aquilaria secundaria 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.

Aquilaria secundaria is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Aquilaria secundaria can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to agarwood plant care, which shares the same genus.

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

Aquilaria secundaria grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Aquilaria secundaria is native to Bangladesh, Bhutan, India, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, also Thailand. In cooler regions, grow Aquilaria secundaria as a houseplant or bring it indoors before the first frost.
