Silver-leaf Heeria Plant Care

Silver-leaf Heeria (Heeria argentea) belongs to the Anacardiaceae family within the Heeria genus.

Silver-leaf Heeria displays a small tree or shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Silver-leaf Heeria produces small clusters of white or pink flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Silver-leaf Heeria 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.

Silver-leaf Heeria thrives in full sun to partial shade.

Heeria argentea tolerates temperatures of 60–85°F. Silver-leaf Heeria prefers humidity levels of 40–70%.

Well-draining sandy soil mix with added organic matter for nutrients. Good drainage is essential for Silver-leaf Heeria to prevent waterlogging, which leads to root rot and fungal issues.

Feed Silver-leaf Heeria every 6 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.

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

Silver-leaf Heeria 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.

Silver-leaf Heeria can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Silver-leaf Heeria 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.

Silver-leaf Heeria 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.

Silver-leaf Heeria can be propagated through seeds, stem cuttings.

Silver-leaf Heeria 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.

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