Golden Shower Tree Plant Care

Golden Shower Tree (Cassia ferruginea) belongs to the Fabaceae family within the Cassia genus. Golden Shower Tree is native to Brazil. Golden Shower Tree is also known as Yellow Cassia.

Golden Shower Tree displays a small to medium-sized tree growth habit, reaching up to 20 ft tall with a spread of approximately 15 ft. Golden Shower Tree produces showy clusters of yellow flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Golden Shower Tree every 7–10 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.

Golden Shower Tree thrives in full sun to partial shade.

Cassia ferruginea tolerates temperatures of 60–85°F. Golden Shower Tree prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Golden Shower Tree to prevent waterlogging, which leads to root rot and fungal issues.

Feed Golden Shower Tree 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 loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Golden Shower 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.

Golden Shower Tree can spread to about 15 ft (4.6 m) and reach about 20 ft (6 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Golden Shower 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.

Golden Shower 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.

Golden Shower Tree can be propagated through seeds, softwood cuttings. Similar propagation techniques also apply to shorthorn senna plant care, which shares the same genus.

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