Sohnreyia excelsa Plant Care

Sohnreyia excelsa (Sohnreyia excelsa) belongs to the Rutaceae family within the Sohnreyia genus. Sohnreyia excelsa is native to the rainforests of the Amazon basin, and was discovered in 1911 by botanical explorer Ernst H.

Sohnreyia excelsa displays a compact, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Sohnreyia excelsa produces small white fragrant flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Sohnreyia excelsa every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Sohnreyia excelsa thrives in full sun to partial shade.

Sohnreyia excelsa tolerates temperatures of 60–85°F. Sohnreyia excelsa prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter. Good drainage is essential for Sohnreyia excelsa to prevent waterlogging, which leads to root rot and fungal issues.

Feed Sohnreyia excelsa every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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. Avoid low spots where water collects after rain.

Sohnreyia excelsa is suited to USDA Zone 13a.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Sohnreyia excelsa can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Sohnreyia excelsa 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 shrub in one year.

Sohnreyia excelsa 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.

Sohnreyia excelsa can be propagated through seeds, stem cuttings.

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

Sohnreyia excelsa grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Sohnreyia excelsa is native to the rainforests of the Amazon basin, and was discovered in 1911 by botanical explorer Ernst H. In cooler regions, grow Sohnreyia excelsa as a houseplant or bring it indoors before the first frost.
