Rose Root Plant Care

Rose Root (Rhodiola rhodantha) belongs to the Crassulaceae family within the Rhodiola genus. Rose Root is also known as Rhodiola.

Rose Root displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Rose Root produces small yellow flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Rose Root every 7–14 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.

Rose Root thrives in full sun to partial shade.

Rhodiola rhodantha tolerates temperatures of 50–75°F. Rose Root prefers humidity levels of 40–60%.

Well-draining sandy soil with added organic matter for moisture retention. Good drainage is essential for Rose Root to prevent waterlogging, which leads to root rot and fungal issues.

Feed Rose Root 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 soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Rose Root is suited to USDA Zone 12a.

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.

Rose Root can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Rose Root 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.

Rose Root is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Rose Root can be propagated through division, seeds. Similar propagation techniques also apply to rhodiola plant care, which shares the same genus.

Rose Root is susceptible to aphids, spider mites, slugs. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Rose Root grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. In cooler regions, grow Rose Root as a houseplant or bring it indoors before the first frost.
