Ashoka Tree Plant Care

Ashoka Tree (Saraca asoca) belongs to the Fabaceae family within the Saraca genus. Ashoka Tree is also known as Sorrowless Tree, Sita Ashok.

Ashoka Tree displays a medium-sized tree, spreading canopy growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Ashoka Tree produces clusters of small, fragrant yellow or orange flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Ashoka Tree 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.

Ashoka Tree thrives in full sun to partial shade.

Saraca asoca tolerates temperatures of 60–85°F. Ashoka Tree prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, rich loamy soil with added organic matter like compost or peat moss. Good drainage is essential for Ashoka Tree to prevent waterlogging, which leads to root rot and fungal issues.

Feed Ashoka Tree every 4 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 full sun to partial shade and well-draining, rich loamy soil with added organic matter like compost or peat moss. Avoid low spots where water collects after rain.

Ashoka Tree 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.

Ashoka Tree can spread to about 20 ft (6.1 m) and reach about 30 ft (9 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Ashoka Tree 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.

Ashoka Tree 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.

Ashoka Tree can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to ashoka tree plant care, which shares the same genus.

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

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