Soapberry Plant Care

Soapberry (Sapindus saponaria) belongs to the Sapindaceae family within the Sapindus genus. Soapberry is native to the Americas. Soapberry is also known as Western soapberry, Jaboncillo.

Soapberry displays a tall, upright tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Soapberry produces small white or yellow flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Soapberry 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.

Soapberry thrives in full sun to partial shade.

Sapindus saponaria tolerates temperatures of 60–85°F. Soapberry prefers humidity levels of 40–70%.

Well-draining loamy soil mix with added compost for nutrients. Good drainage is essential for Soapberry to prevent waterlogging, which leads to root rot and fungal issues.

Feed Soapberry 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 loamy soil mix with added compost for nutrients. Avoid low spots where water collects after rain.

Soapberry 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.

Soapberry 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 Soapberry 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.

Soapberry 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.

Soapberry can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to indian soapberry plant care, which shares the same genus.

Soapberry 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.

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